+# OpenSpec Project
+
+This document provides instructions for AI coding assistants on how to use OpenSpec conventions for spec-driven development. Follow these rules precisely when working on OpenSpec-enabled projects.
+
+This project uses OpenSpec for spec-driven development. Specifications are the source of truth.
+
+See @openspec/AGENTS.md for detailed conventions and guidelines.
+<!-- OPENSPEC:END -->
+
+## Complexity Management
+
+**Default to minimal solutions:**
+- Propose <100 lines of new code for features
+- Prefer single-file implementations until proven insufficient
+- Avoid frameworks, abstractions, and optimizations without clear justification
+- Choose boring, well-understood patterns over novel approaches
+
+**Question requests for complexity:**
+- Caching? → Ask for performance data and targets
+- New framework? → Suggest plain code first
+- Extra layers? → Start with the thinnest viable design
+
+**Justify complexity with data:**
+- Performance metrics showing current solution is too slow
+- Concrete scale requirements (e.g., >1000 users, >100MB data)
+- Multiple proven use cases requiring an abstraction
+
+## Package Manager
+Always use pnpm (NOT npm or yarn) for all Node.js package management:
+- Install dependencies: `pnpm install`
+- Add packages: `pnpm add [package]`
+- Run scripts: `pnpm run [script]`
+
+## Git Commits
+Use conventional commits with these rules:
+- Format: `type(scope): subject` (e.g., `fix: resolve auth error`, `feat(api): add user endpoint`)
+- Keep commit messages to ONE line only - no body or footer
+- Common types: feat, fix, docs, style, refactor, test, chore
+- Never add co-authorship lines or attribution

-# Comprehensive Retrospective: Creating an OpenSpec Change Proposal
-
-## Executive Summary
-
-This document consolidates learnings from creating the `bulk-validation-interactive-selection` change proposal for OpenSpec. The process revealed critical gaps in documentation, unhelpful error messages, and areas where the system could be more user-friendly. While OpenSpec's core functionality works correctly, the user experience for creating changes needs significant improvement.

-
----
-
-## Errors Encountered
-
-### Error 1: Misunderstanding Delta Structure
-**Error Message:** `✗ [ERROR] deltas: Change must have at least one delta`
-
-**What Happened:**
-Initially attempted to define deltas directly in the `proposal.md` file using markdown sections like:
-```markdown
-### Delta: Add validate-all command
-**Type**: Feature addition
-**Effort**: Small (< 100 lines)
-```
-
-**Root Cause:**
-Fundamental misunderstanding of how OpenSpec processes deltas. Deltas are derived from spec files in the change's `specs/` directory, not from the proposal itself.
-
-**Discovery Process:**
-- Examined `ChangeParser` class in `/src/core/parsers/change-parser.ts`
-- Found that `parseDeltaSpecs()` method looks for spec files in `specs/` subdirectory
-- Learned that deltas are extracted by comparing spec files against existing specs
-
-### Error 2: Missing Operation Prefix in Section Headers
-**Error Message:** `✗ [ERROR] deltas: Change must have at least one delta`
-
-**What Happened:**
-Created new spec files with standard `## Requirements` headers instead of operation-prefixed headers.
-
-**Root Cause:**
-Failed to understand that ALL spec files in a change need operation prefixes (`ADDED`, `MODIFIED`, etc.) in their section headers, regardless of whether they're new specs or modifications.
-
-**Discovery Process:**
-- Created new specs with `## Requirements` → No deltas detected
-- Changed to `## ADDED Requirements` → Deltas detected successfully!
-- Realized creating new specs works perfectly fine once properly formatted
-
-**Important Clarification:**
-OpenSpec fully supports creating new specs. They appear as ADDED operations in the deltas. My initial analysis incorrectly suggested this was a limitation, but it was actually just a formatting issue.
-
-### Error 3: Improper Scenario Formatting
-**Error Message:** 
-```
-✗ [ERROR] deltas.0.requirements.0.scenarios: Requirement must have at least one scenario
-✗ [ERROR] deltas.1.requirements.0.scenarios: Requirement must have at least one scenario
-```
-
-**What Happened:**
-Formatted scenarios as bullet lists under a bold "Scenarios:" label:
-```markdown
-**Scenarios:**
-- **WHEN** executing command
-- **THEN** expected behavior
-```
-
-**Root Cause:**
-OpenSpec's parser expects scenarios to be defined as level 4 headers (`####`) with specific formatting:
-```markdown
-#### Scenario: Descriptive scenario name
-
-- **WHEN** executing command
-- **THEN** expected behavior
-```
-
-**Discovery Process:**
-- Checked parsed JSON output: `npx openspec change show bulk-validation-interactive-selection --json`
-- Saw `"scenarios": []` empty array despite having scenario content
-- Examined working spec files and found the `#### Scenario:` header pattern
-
-### Error 4: File Path Confusion
-**Initial Confusion:**
-Wasn't clear whether to create specs that would become part of the main `openspec/specs/` or just define them in the change.
-
-**Resolution:**
-Learned that changes can:
-1. Create new specs (they start in `changes/{change-name}/specs/` and move to `openspec/specs/` when archived)
-2. Modify existing specs (by creating a spec file with the same name as one in `openspec/specs/`)
-3. The validation system detects both patterns and creates appropriate deltas
-
----
-
-## System Issues vs User Errors
-
-### System Issues / Bugs
-
-#### 1. Unhelpful Error Messages ⚠️
-**Issue:** `✗ [ERROR] deltas: Change must have at least one delta`
-
-**Why This Is a System Problem:**
-- Error message provides no guidance on HOW to create deltas
-- Doesn't mention that deltas come from `specs/` subdirectory
-- Doesn't explain the required section headers
-- A better error would be: "No deltas found. Ensure your change has a specs/ directory with .md files containing sections like '## ADDED Requirements'"
-
-#### 2. Silent Scenario Parsing Failures ⚠️
-**Issue:** When scenarios were formatted incorrectly, they were silently ignored
-
-**Why This Is a System Problem:**
-- Parser silently returns empty scenarios array instead of warning
-- No validation error explaining the format issue
-- User gets "Requirement must have at least one scenario" without knowing their scenarios exist but aren't parsed
-
-**Evidence:**
-```json
-{
-  "text": "The CLI SHALL provide a top-level `show` command with interactive selection.",
-  "scenarios": []  // Silent failure - scenarios existed but weren't parsed
-}
-```
-
-#### 3. No Validation for Proposal Structure During Creation
-**Issue:** System allows creating invalid proposals without early feedback
-
-**Why This Is a System Problem:**
-- No scaffolding or template commands
-- No incremental validation as you build
-- Must fully create the change before discovering structural issues
-
-### User Errors (My Mistakes)
-
-#### 1. Trying to Define Deltas in Proposal.md
-- Incorrectly assumed deltas could be inline in the proposal
-- System correctly expects deltas in separate spec files
-
-#### 2. Using Wrong Section Headers
-- Used `## Requirements` instead of `## ADDED Requirements`
-- Convention is documented in existing changes, but I didn't examine carefully
-
-#### 3. Wrong Scenario Format
-- Used bullet lists instead of `#### Scenario:` headers
-- Made assumptions instead of checking existing patterns
-
-### Gray Areas
-
-1. **Documentation gaps** - While examples exist, there's no comprehensive "How to Create a Change" guide
-2. **Lack of tooling** - No scaffolding commands to create properly structured changes
-
----
-
-## Documentation Gaps Analysis
-
-### Critical Gaps in openspec/README.md
-
-#### 1. Scenario Format - COMPLETELY MISSING ⚠️
-**What README Shows:** No scenario examples at all
-
-**What's Actually Required:**
-```markdown
-#### Scenario: Descriptive name
-- **WHEN** condition
-- **THEN** expected outcome
-- **AND** additional outcomes
-```
-
-**Impact:** This was the biggest struggle. The README mentions requirements but never shows how to write scenarios. Without this, requirements fail validation.
-
-#### 2. Complete Spec File Example - MISSING
-**What README Shows:** Only fragments
-
-**What's Actually Needed:** A complete working example showing:
-- Full spec file structure
-- Proper requirement format
-- Scenario formatting
-- All required elements
-
-#### 3. Validation Commands - NOT MENTIONED
-**Missing from README:**
-- `npx openspec change validate <change-name>`
-- `npx openspec change show <change-name> --json`
-- The `--strict` flag for catching warnings
-
-#### 4. Delta Detection Explanation - INCOMPLETE
-**What's Missing:**
-- WHERE the system looks for specs (specs/ subdirectory)
-- THAT deltas are automatically extracted
-- HOW to debug when deltas aren't detected
-- WHAT error messages mean
-
-### Misleading Documentation
-
-#### "Store only the changes" - MISLEADING
-**Line 145:** `# - Store only the changes (not complete future state)`
-
-**Problem:** This suggests storing diffs or partial content. In reality, you need:
-- Complete requirements in their final form
-- Full scenario definitions
-- The entire requirement text
-
-### Documentation That Was Helpful
-1. Delta section headers (`## ADDED Requirements`) - clearly documented
-2. Directory structure - excellent visualization
-3. When to create proposals - well defined
-
----
-
-## Key Learnings
-
-### 1. OpenSpec's Delta Detection Algorithm
-The system follows this process:
-1. Scans `openspec/changes/{change-name}/specs/` directory
-2. For each spec file found, parses for delta sections (`ADDED`, `MODIFIED`, `REMOVED`, `RENAMED`)
-3. Creates delta objects with operation type, affected spec, and requirements
-4. Validates that at least one delta exists for the change to be valid
-
-**Important:** Creating entirely new specs is fully supported! New specs use `## ADDED Requirements` and appear as ADDED operations in the deltas.
-
-### 2. Spec File Structure Requirements
-Valid spec files must follow this structure:
-```markdown
-# Spec Title
-
-## [ADDED|MODIFIED|REMOVED|RENAMED] Requirements
-
-### Requirement: Clear requirement statement
-
-The requirement description using SHALL/SHOULD/MAY.
-
-#### Scenario: Scenario name
-
-- **WHEN** condition
-- **THEN** expected outcome
-- **AND** additional outcomes
-```
-
-### 3. Change Proposal Structure
-A valid change must have:
-- `## Why` section - explaining the motivation
-- `## What Changes` section - summarizing the changes
-- `specs/` directory with properly formatted spec files containing deltas
-- Each delta must have at least one requirement with at least one scenario
-
-### 4. Validation Commands Are Essential
-```bash
-# Basic validation
-npx openspec change validate {change-name}
-
-# Strict validation (recommended)
-npx openspec change validate {change-name} --strict
-
-# Debug delta detection
-npx openspec change show {change-name} --json | jq '.deltas'
-```
-
----
-
-## Recommendations
-
-### High Priority (System Bugs to Fix)
-
-1. **Improve Error Messages**
-   - Add actionable guidance to error messages
-   - Example: "No deltas found. Check: 1) specs/ directory exists, 2) Files use ## ADDED Requirements headers, 3) Each requirement has #### Scenario: sections"
-
-2. **Add Warnings for Malformed Content**
-   - Warn when scenarios exist but aren't properly formatted
-   - Show which line/file has the issue
-
-3. **Add Delta Detection Debugging**
-   - Command like `openspec change debug-deltas {change-name}`
-   - Show which files were scanned, what was found, what was rejected
-
-### Medium Priority (Documentation Improvements)
-
-1. **Add Complete Working Example to README**
-   - Full change proposal with all files
-   - Properly formatted specs with scenarios
-   - Show the validation output
-
-2. **Add Troubleshooting Section**
-   - Common errors and their solutions
-   - How to debug delta detection
-   - Scenario formatting requirements
-
-3. **Add Validation Best Practices**
-   - When to use `--strict`
-   - How to use JSON output for debugging
-   - Common validation patterns
-
-### Low Priority (Developer Experience)
-
-1. **Add Scaffolding Command**
-   ```bash
-   openspec change scaffold {change-name}
-   ```
-   - Creates proper directory structure
-   - Includes template files with correct formatting
-   - Adds example scenarios
-
-2. **Add Interactive Creation Wizard**
-   - Guide users through change creation
-   - Validate as they go
-   - Suggest fixes for common issues
-
-3. **Add Auto-fix Capability**
-   - `--fix` flag to correct common formatting issues
-   - Convert bullet list scenarios to proper headers
-   - Add missing operation prefixes
-
----
-
-## Conclusion
-
-The OpenSpec system works correctly for its intended design, but the user experience for creating changes needs significant improvement. The core issues stem from:
-
-### System Issues
-- **Unhelpful error messages** that don't guide users to solutions
-- **Silent parsing failures** that provide no feedback about malformed content
-- **Lack of debugging tools** to understand what went wrong
-
-### Documentation Issues
-- **Critical formatting requirements missing** (especially scenario format)
-- **No complete working examples** showing all required elements
-- **Validation commands not documented** despite being essential
-
-### User Issues
-- **Incorrect assumptions** about how the system works
-- **Not examining existing patterns** carefully enough
-- **Trying to shortcut** instead of following established conventions
-
-### The Path Forward
-
-With better error messages, complete documentation, and basic tooling support, most of the errors encountered could be prevented. The system's delta-centric approach is powerful and ensures changes are atomic and trackable, but it needs to be more discoverable and user-friendly.
-
-The most impactful improvements would be:
-1. Adding scenario format documentation to the README
-2. Improving error messages with actionable guidance
-3. Creating a scaffolding command for new changes
-
-These changes would transform OpenSpec from a system that works correctly but is hard to use, into one that actively helps developers succeed.

 # OpenSpec
 
-A specification-driven development system for maintaining living documentation alongside your code.
+OpenSpec aligns humans and AI coding assistants with spec-driven development so you agree on what to build before any code is written. **No API keys required.**
 
-## Installation
+## Why OpenSpec?
 
-```bash
-npm install -g openspec
+AI coding assistants are powerful but unpredictable when requirements live in chat history. OpenSpec adds a lightweight specification workflow that locks intent before implementation, giving you deterministic, reviewable outputs.
+
+Key outcomes:
+- Human and AI stakeholders agree on specs before work begins.
+- Structured change folders (proposals, tasks, and spec updates) keep scope explicit and auditable.
+- Shared visibility into what's proposed, active, or archived.
+- Works with the AI tools you already use: custom slash commands where supported, context rules everywhere else.
+
+## How It Works
+
+```

+└────────────────────┘
+
+1. Draft a change proposal that captures the spec updates you want.
+2. Review the proposal with your AI assistant until everyone agrees.
+3. Implement tasks that reference the agreed specs.
+4. Archive the change to merge the approved updates back into the source-of-truth specs.
 ```
 
-## Quick Start
+## Getting Started
+
+### Supported AI Tools
+
+#### Native Slash Commands
+These tools have built-in OpenSpec commands. Select the OpenSpec integration when prompted.
+
+| Tool | Commands |
+|------|----------|
+| **Claude Code** | `/openspec:proposal`, `/openspec:apply`, `/openspec:archive` |
+| **Cursor** | `/openspec-proposal`, `/openspec-apply`, `/openspec-archive` |
+
+#### AGENTS.md Compatible
+These tools automatically read workflow instructions from `openspec/AGENTS.md`. Ask them to follow the OpenSpec workflow if they need a reminder. Learn more about the [AGENTS.md convention](https://agents.md/).
+
+| Tools |
+|-------|
+| Codex • Amp • Jules • OpenCode • Gemini CLI • GitHub Copilot • Others |
+
+### Install & Initialize
+
+#### Prerequisites
+- **Node.js >= 20.19.0** - Check your version with `node --version`
+
+#### Step 1: Install the CLI globally
 
 ```bash
-# Initialize OpenSpec in your project
+npm install -g @fission-ai/openspec@latest
+```
+
+Verify installation:
+```bash
+openspec --version
+```
+
+#### Step 2: Initialize OpenSpec in your project
+
+Navigate to your project directory:
+```bash
+cd my-project
+```
+
+Run the initialization:
+```bash
 openspec init
-
-# Update existing OpenSpec instructions (team-friendly)
-openspec update
-
-# List specs or changes
-openspec spec list        # specs (IDs by default; use --long for details)
-openspec change list      # changes (IDs by default; use --long for details)
-
-# Show differences between specs and proposed changes
-openspec diff [change-name]
-
-# Archive completed changes
-openspec archive [change-name]
 ```
 
-## Commands
+**What happens during initialization:**
+- You'll be prompted to select your AI tool (Claude Code, Cursor, etc.)
+- OpenSpec automatically configures slash commands or `AGENTS.md` based on your selection
+- A new `openspec/` directory structure is created in your project
 
-### `openspec init`
+**After setup:**
+- Primary AI tools can trigger `/openspec` workflows without additional configuration
+- Run `openspec list` to verify the setup and view any active changes
 
-Initializes OpenSpec in your project by creating:
-- `openspec/` directory structure
-- `openspec/README.md` with OpenSpec instructions
-- AI tool configuration files (based on your selection)
+### Create Your First Change
 
-### `openspec update`
+Here's a real example showing the complete OpenSpec workflow. This works with any AI tool. Those with native slash commands will recognize the shortcuts automatically.
 
-Updates OpenSpec instructions to the latest version. This command is **team-friendly** and only updates files that already exist:
+#### 1. Draft the Proposal
+Start by asking your AI to create a change proposal:
 
-- Always updates `openspec/README.md` with the latest OpenSpec instructions
-- **Only updates existing AI tool configuration files** (e.g., CLAUDE.md, CURSOR.md)
-- **Never creates new AI tool configuration files**
-- Preserves content outside of OpenSpec markers in AI tool files
+```text
+You: Create an OpenSpec change proposal for adding profile search filters by role and team
+     (Shortcut for tools with slash commands: /openspec:proposal Add profile search filters)
 
-This allows team members to use different AI tools without conflicts. Each developer can maintain their preferred AI tool configuration file, and `openspec update` will respect their choice.
+AI:  I'll create an OpenSpec change proposal for profile filters.
+     *Scaffolds openspec/changes/add-profile-filters/ with proposal.md, tasks.md, spec deltas.*
+```
 
-### `openspec spec`
+#### 2. Verify & Review
+Check that the change was created correctly and review the proposal:
 
-Manage and view specifications.
+```bash
+$ openspec list                             # Confirm the change folder exists
+$ openspec validate add-profile-filters     # Validate spec formatting
+$ openspec show add-profile-filters         # Review proposal, tasks, and spec delta
+```
 
-Examples:
-- `openspec spec show <spec-id>`
-  - Text mode: prints raw `spec.md` content
-  - JSON mode (`--json`): returns minimal, stable shape
-    - Filters are JSON-only: `--requirements`, `--no-scenarios`, `-r/--requirement <1-based>`
-- `openspec spec list`
-  - Prints IDs only by default
-  - Use `--long` to include `title` and `[requirements N]`
-- `openspec spec validate <spec-id>`
-  - Text: human-readable summary to stdout/stderr
-  - `--json` for structured report
+#### 3. Refine the Specs
+Iterate on the specifications until they match your needs:
 
-### `openspec change`
+```text
+You: Can you add acceptance criteria for the role and team filters?
 
-Manage and view change proposals.
+AI:  I'll update the spec delta with scenarios for role and team filters.
+     *Edits openspec/changes/add-profile-filters/specs/profile/spec.md and tasks.md.*
+```
 
-Examples:
-- `openspec change show <change-id>`
-  - Text mode: prints raw `proposal.md` content
-  - JSON mode (`--json`): `{ id, title, deltaCount, deltas }`
-  - Filtering is JSON-only: `--deltas-only` (alias: `--requirements-only`, deprecated)
-- `openspec change list`
-  - Prints IDs only by default
-  - Use `--long` to include `title` and counts `[deltas N] [tasks x/y]`
-- `openspec change validate <change-id>`
-  - Text: human-readable result
-  - `--json` for structured report
+#### 4. Implement the Change
+Once specs look good, start implementation:
 
-### `openspec diff [change-name]`
+```text
+You: The specs look good. Let's implement this change.
+     (Shortcut for tools with slash commands: /openspec:apply add-profile-filters)
 
-Shows the differences between current specs and proposed changes:
-- Displays a unified diff format
-- Helps review what will change before implementation
-- Useful for pull request reviews
+AI:  I'll work through the tasks in the add-profile-filters change.
+     *Implements tasks from openspec/changes/add-profile-filters/tasks.md*
+     *Marks tasks complete: Task 1.1 ✓, Task 1.2 ✓, Task 2.1 ✓...*
+```
 
-### `openspec archive [change-name]`
+#### 5. Archive the Completed Change
+After implementation is complete, archive the change:
 
-Archives a completed change:
-- Moves change from `openspec/changes/` to `openspec/changes/archive/`
-- Adds a date prefix to the archived change
-- Updates specs to reflect the new state
-- Use `--skip-specs` to archive without updating specs (for abandoned changes)
+```text
+AI:  All tasks are complete. The implementation is ready.
 
-## Team Collaboration
+You: Please archive the change
+     (Shortcut for tools with slash commands: /openspec:archive add-profile-filters)
 
-OpenSpec is designed for team collaboration:
+AI:  I'll archive the add-profile-filters change.
+     *Runs: openspec archive add-profile-filters*
+     ✓ Change archived successfully. Specs updated. Ready for the next feature!
+```
 
-1. **AI Tool Flexibility**: Each team member can use their preferred AI assistant (Claude, Cursor, etc.)
-2. **Non-Invasive Updates**: The `update` command only modifies existing files, never forcing tools on team members
-3. **Specification Sharing**: The `openspec/` directory contains shared specifications that all team members work from
-4. **Change Tracking**: Proposed changes are visible to all team members for review before implementation
+Or run the command yourself in terminal:
+```bash
+$ openspec archive add-profile-filters  # Archive the completed change
+```
+
+**Note:** Tools with native slash commands (Claude Code, Cursor) can use the shortcuts shown. All other tools work with natural language requests to "create an OpenSpec proposal", "apply the OpenSpec change", or "archive the change".
+
+## Command Reference
+
+```bash
+openspec list               # View active change folders
+openspec view               # Interactive dashboard of specs and changes
+openspec show <change>      # Display change details (proposal, tasks, spec updates)
+openspec validate <change>  # Check spec formatting and structure
+openspec archive <change>   # Move a completed change into archive/
+```
+
+## Example: How AI Creates OpenSpec Files
+
+When you ask your AI assistant to "add two-factor authentication", it creates:
+
+```
+openspec/
+├── specs/
+│   └── auth/
+│       └── spec.md           # Current auth spec (if exists)
+└── changes/
+    └── add-2fa/              # AI creates this entire structure
+        ├── proposal.md       # Why and what changes
+        ├── tasks.md          # Implementation checklist
+        ├── design.md         # Technical decisions (optional)
+        └── specs/
+            └── auth/
+                └── spec.md   # Delta showing additions
+```
+
+### AI-Generated Spec (created in `openspec/specs/auth/spec.md`):
+
+```markdown
+# Auth Specification
+
+## Purpose
+Authentication and session management.
+
+## Requirements
+### Requirement: User Authentication
+The system SHALL issue a JWT on successful login.
+
+#### Scenario: Valid credentials
+- WHEN a user submits valid credentials
+- THEN a JWT is returned
+```
+
+### AI-Generated Change Delta (created in `openspec/changes/add-2fa/specs/auth/spec.md`):
+
+```markdown
+# Delta for Auth
+
+## ADDED Requirements
+### Requirement: Two-Factor Authentication
+The system MUST require a second factor during login.
+
+#### Scenario: OTP required
+- WHEN a user submits valid credentials
+- THEN an OTP challenge is required
+```
+
+### AI-Generated Tasks (created in `openspec/changes/add-2fa/tasks.md`):
+
+```markdown
+## 1. Database Setup
+- [ ] 1.1 Add OTP secret column to users table
+- [ ] 1.2 Create OTP verification logs table
+
+## 2. Backend Implementation  
+- [ ] 2.1 Add OTP generation endpoint
+- [ ] 2.2 Modify login flow to require OTP
+- [ ] 2.3 Add OTP verification endpoint
+
+## 3. Frontend Updates
+- [ ] 3.1 Create OTP input component
+- [ ] 3.2 Update login flow UI
+```
+
+**Important:** You don't create these files manually. Your AI assistant generates them based on your requirements and the existing codebase.
+
+## Understanding OpenSpec Files
+
+### Delta Format
+
+Deltas are "patches" that show how specs change:
+
+- **`## ADDED Requirements`** - New capabilities
+- **`## MODIFIED Requirements`** - Changed behavior (include complete updated text)
+- **`## REMOVED Requirements`** - Deprecated features
+
+**Format requirements:**
+- Use `### Requirement: <name>` for headers
+- Every requirement needs at least one `#### Scenario:` block
+- Use SHALL/MUST in requirement text
+
+## How OpenSpec Compares
+
+### vs. Kiro.dev
+OpenSpec groups every change for a feature in one folder (`openspec/changes/feature-name/`), making it easy to track related specs, tasks, and designs together. Kiro spreads updates across multiple spec folders, which can make feature tracking harder.
+
+### vs. No Specs
+Without specs, AI coding assistants generate code from vague prompts, often missing requirements or adding unwanted features. OpenSpec brings predictability by agreeing on the desired behavior before any code is written.
+
+## Team Adoption
+
+1. **Initialize OpenSpec** – Run `openspec init` in your repo.
+2. **Start with new features** – Ask your AI to capture upcoming work as change proposals.
+3. **Grow incrementally** – Each change archives into living specs that document your system.
+4. **Stay flexible** – Different teammates can use Claude Code, Cursor, or any AGENTS.md-compatible tool while sharing the same specs.
+
+Run `openspec update` whenever someone switches tools so your agents pick up the latest instructions and slash-command bindings.
+
+## Updating OpenSpec
+
+1. **Upgrade the package**
+   ```bash
+   npm install -g @fission-ai/openspec@latest
+   ```
+2. **Refresh agent instructions**
+   - Run `openspec update` inside each project to regenerate AI guidance and ensure the latest slash commands are active.

-
-## Notes
-
-- The legacy `openspec list` command is deprecated. Use `openspec spec list` and `openspec change list`.
-- Text output is raw-first (no formatting or filtering). Prefer `--json` for tooling-friendly output.
-- Global `--no-color` disables ANSI colors and respects `NO_COLOR`.
+- Install dependencies: `pnpm install`

+# OpenSpec Instructions
+
+Instructions for AI coding assistants using OpenSpec for spec-driven development.
+
+## TL;DR Quick Checklist
+
+- Search existing work: `openspec spec list --long`, `openspec list` (use `rg` only for full-text search)
+- Decide scope: new capability vs modify existing capability
+- Pick a unique `change-id`: kebab-case, verb-led (`add-`, `update-`, `remove-`, `refactor-`)
+- Scaffold: `proposal.md`, `tasks.md`, `design.md` (only if needed), and delta specs per affected capability
+- Write deltas: use `## ADDED|MODIFIED|REMOVED|RENAMED Requirements`; include at least one `#### Scenario:` per requirement
+- Validate: `openspec validate [change-id] --strict` and fix issues
+- Request approval: Do not start implementation until proposal is approved
+
+## Three-Stage Workflow
+
+### Stage 1: Creating Changes
+Create proposal when you need to:
+- Add features or functionality
+- Make breaking changes (API, schema)
+- Change architecture or patterns  
+- Optimize performance (changes behavior)
+- Update security patterns
+
+Triggers (examples):
+- "Help me create a change proposal"
+- "Help me plan a change"
+- "Help me create a proposal"
+- "I want to create a spec proposal"
+- "I want to create a spec"
+
+Loose matching guidance:
+- Contains one of: `proposal`, `change`, `spec`
+- With one of: `create`, `plan`, `make`, `start`, `help`
+
+Skip proposal for:
+- Bug fixes (restore intended behavior)
+- Typos, formatting, comments
+- Dependency updates (non-breaking)
+- Configuration changes
+- Tests for existing behavior
+
+**Workflow**
+1. Review `openspec/project.md`, `openspec list`, and `openspec list --specs` to understand current context.
+2. Choose a unique verb-led `change-id` and scaffold `proposal.md`, `tasks.md`, optional `design.md`, and spec deltas under `openspec/changes/<id>/`.
+3. Draft spec deltas using `## ADDED|MODIFIED|REMOVED Requirements` with at least one `#### Scenario:` per requirement.
+4. Run `openspec validate <id> --strict` and resolve any issues before sharing the proposal.
+
+### Stage 2: Implementing Changes
+1. **Read proposal.md** - Understand what's being built
+2. **Read design.md** (if exists) - Review technical decisions
+3. **Read tasks.md** - Get implementation checklist
+4. **Implement tasks sequentially** - Complete in order
+5. **Mark complete immediately** - Update `- [x]` after each task
+6. **Approval gate** - Do not start implementation until the proposal is reviewed and approved
+
+### Stage 3: Archiving Changes
+After deployment, create separate PR to:
+- Move `changes/[name]/` → `changes/archive/YYYY-MM-DD-[name]/`
+- Update `specs/` if capabilities changed
+- Use `openspec archive [change] --skip-specs` for tooling-only changes
+- Run `openspec validate --strict` to confirm the archived change passes checks
+
+## Before Any Task
+
+**Context Checklist:**
+- [ ] Read relevant specs in `specs/[capability]/spec.md`
+- [ ] Check pending changes in `changes/` for conflicts
+- [ ] Read `openspec/project.md` for conventions
+- [ ] Run `openspec list` to see active changes
+- [ ] Run `openspec list --specs` to see existing capabilities
+
+**Before Creating Specs:**
+- Always check if capability already exists
+- Prefer modifying existing specs over creating duplicates
+- Use `openspec show [spec]` to review current state
+- If request is ambiguous, ask 1–2 clarifying questions before scaffolding
+
+### Search Guidance
+- Enumerate specs: `openspec spec list --long` (or `--json` for scripts)
+- Enumerate changes: `openspec list` (or `openspec change list --json` - deprecated but available)
+- Show details:
+  - Spec: `openspec show <spec-id> --type spec` (use `--json` for filters)
+  - Change: `openspec show <change-id> --json --deltas-only`
+- Full-text search (use ripgrep): `rg -n "Requirement:|Scenario:" openspec/specs`
+
+## Quick Start
+
+### CLI Commands
+
+```bash
+# Essential commands
+openspec list                  # List active changes
+openspec list --specs          # List specifications
+openspec show [item]           # Display change or spec
+openspec diff [change]         # Show spec differences
+openspec validate [item]       # Validate changes or specs
+openspec archive [change]      # Archive after deployment
+
+# Project management
+openspec init [path]           # Initialize OpenSpec
+openspec update [path]         # Update instruction files
+
+# Interactive mode
+openspec show                  # Prompts for selection
+openspec validate              # Bulk validation mode
+
+# Debugging
+openspec show [change] --json --deltas-only
+openspec validate [change] --strict
+```
+
+### Command Flags
+
+- `--json` - Machine-readable output
+- `--type change|spec` - Disambiguate items
+- `--strict` - Comprehensive validation
+- `--no-interactive` - Disable prompts
+- `--skip-specs` - Archive without spec updates

+
+## Creating Change Proposals
+
+### Decision Tree
+
+```
+New request?
+├─ Bug fix restoring spec behavior? → Fix directly
+├─ Typo/format/comment? → Fix directly  
+├─ New feature/capability? → Create proposal
+├─ Breaking change? → Create proposal
+├─ Architecture change? → Create proposal
+└─ Unclear? → Create proposal (safer)
+```
+
+### Proposal Structure
+
+1. **Create directory:** `changes/[change-id]/` (kebab-case, verb-led, unique)
+
+2. **Write proposal.md:**
+```markdown
+## Why
+[1-2 sentences on problem/opportunity]
+
+## What Changes
+- [Bullet list of changes]
+- [Mark breaking changes with **BREAKING**]
+
+## Impact
+- Affected specs: [list capabilities]
+- Affected code: [key files/systems]
+```
+
+3. **Create spec deltas:** `specs/[capability]/spec.md`
+```markdown
+## ADDED Requirements
+### Requirement: New Feature
+The system SHALL provide...
+
+#### Scenario: Success case
+- **WHEN** user performs action
+- **THEN** expected result
+
+## MODIFIED Requirements
+### Requirement: Existing Feature
+[Complete modified requirement]
+
+## REMOVED Requirements
+### Requirement: Old Feature
+**Reason**: [Why removing]
+**Migration**: [How to handle]
+```
+If multiple capabilities are affected, create multiple delta files under `changes/[change-id]/specs/<capability>/spec.md`—one per capability.
+
+4. **Create tasks.md:**
+```markdown
+## 1. Implementation
+- [ ] 1.1 Create database schema
+- [ ] 1.2 Implement API endpoint
+- [ ] 1.3 Add frontend component
+- [ ] 1.4 Write tests
+```
+
+5. **Create design.md when needed:**
+Create `design.md` if any of the following apply; otherwise omit it:
+- Cross-cutting change (multiple services/modules) or a new architectural pattern
+- New external dependency or significant data model changes
+- Security, performance, or migration complexity
+- Ambiguity that benefits from technical decisions before coding
+
+Minimal `design.md` skeleton:
+```markdown
+## Context
+[Background, constraints, stakeholders]
+
+## Goals / Non-Goals
+- Goals: [...]
+- Non-Goals: [...]
+
+## Decisions
+- Decision: [What and why]
+- Alternatives considered: [Options + rationale]
+
+## Risks / Trade-offs
+- [Risk] → Mitigation
+
+## Migration Plan
+[Steps, rollback]
+
+## Open Questions
+- [...]
+```
+
+## Spec File Format
+
+### Critical: Scenario Formatting
+
+**CORRECT** (use #### headers):
+```markdown
+#### Scenario: User login success
+- **WHEN** valid credentials provided
+- **THEN** return JWT token
+```
+
+**WRONG** (don't use bullets or bold):
+```markdown
+- **Scenario: User login**  ❌
+**Scenario**: User login     ❌
+### Scenario: User login      ❌
+```
+
+Every requirement MUST have at least one scenario.
+
+### Requirement Wording
+- Use SHALL/MUST for normative requirements (avoid should/may unless intentionally non-normative)
+
+### Delta Operations
+
+- `## ADDED Requirements` - New capabilities
+- `## MODIFIED Requirements` - Changed behavior
+- `## REMOVED Requirements` - Deprecated features
+- `## RENAMED Requirements` - Name changes
+
+Headers matched with `trim(header)` - whitespace ignored.
+
+#### When to use ADDED vs MODIFIED
+- ADDED: Introduces a new capability or sub-capability that can stand alone as a requirement. Prefer ADDED when the change is orthogonal (e.g., adding "Slash Command Configuration") rather than altering the semantics of an existing requirement.
+- MODIFIED: Changes the behavior, scope, or acceptance criteria of an existing requirement. Always paste the full, updated requirement content (header + all scenarios). The archiver will replace the entire requirement with what you provide here; partial deltas will drop previous details.
+- RENAMED: Use when only the name changes. If you also change behavior, use RENAMED (name) plus MODIFIED (content) referencing the new name.
+
+Common pitfall: Using MODIFIED to add a new concern without including the previous text. This causes loss of detail at archive time. If you aren’t explicitly changing the existing requirement, add a new requirement under ADDED instead.
+
+Authoring a MODIFIED requirement correctly:
+1) Locate the existing requirement in `openspec/specs/<capability>/spec.md`.
+2) Copy the entire requirement block (from `### Requirement: ...` through its scenarios).
+3) Paste it under `## MODIFIED Requirements` and edit to reflect the new behavior.
+4) Ensure the header text matches exactly (whitespace-insensitive) and keep at least one `#### Scenario:`.
+
+Example for RENAMED:
+```markdown
+## RENAMED Requirements
+- FROM: `### Requirement: Login`
+- TO: `### Requirement: User Authentication`
+```
+
+## Troubleshooting
+
+### Common Errors
+
+**"Change must have at least one delta"**
+- Check `changes/[name]/specs/` exists with .md files
+- Verify files have operation prefixes (## ADDED Requirements)
+
+**"Requirement must have at least one scenario"**
+- Check scenarios use `#### Scenario:` format (4 hashtags)
+- Don't use bullet points or bold for scenario headers
+
+**Silent scenario parsing failures**
+- Exact format required: `#### Scenario: Name`
+- Debug with: `openspec show [change] --json --deltas-only`
+
+### Validation Tips
+
+```bash
+# Always use strict mode for comprehensive checks
+openspec validate [change] --strict
+
+# Debug delta parsing
+openspec show [change] --json | jq '.deltas'
+
+# Check specific requirement
+openspec show [spec] --json -r 1
+```
+
+## Happy Path Script
+
+```bash
+# 1) Explore current state
+openspec spec list --long
+openspec list
+# Optional full-text search:
+# rg -n "Requirement:|Scenario:" openspec/specs
+# rg -n "^#|Requirement:" openspec/changes
+
+# 2) Choose change id and scaffold
+CHANGE=add-two-factor-auth
+mkdir -p openspec/changes/$CHANGE/{specs/auth}
+printf "## Why\n...\n\n## What Changes\n- ...\n\n## Impact\n- ...\n" > openspec/changes/$CHANGE/proposal.md
+printf "## 1. Implementation\n- [ ] 1.1 ...\n" > openspec/changes/$CHANGE/tasks.md
+
+# 3) Add deltas (example)
+cat > openspec/changes/$CHANGE/specs/auth/spec.md << 'EOF'
+## ADDED Requirements
+### Requirement: Two-Factor Authentication
+Users MUST provide a second factor during login.
+
+#### Scenario: OTP required
+- **WHEN** valid credentials are provided
+- **THEN** an OTP challenge is required
+EOF
+
+# 4) Validate
+openspec validate $CHANGE --strict
+```
+
+## Multi-Capability Example
+
+```
+openspec/changes/add-2fa-notify/
+├── proposal.md
+├── tasks.md
+└── specs/
+    ├── auth/
+    │   └── spec.md   # ADDED: Two-Factor Authentication
+    └── notifications/
+        └── spec.md   # ADDED: OTP email notification
+```
+
+auth/spec.md
+```markdown
+## ADDED Requirements
+### Requirement: Two-Factor Authentication
+...
+```
+
+notifications/spec.md
+```markdown
+## ADDED Requirements
+### Requirement: OTP Email Notification
+...
+```
+
+## Best Practices
+
+### Simplicity First
+- Default to <100 lines of new code
+- Single-file implementations until proven insufficient
+- Avoid frameworks without clear justification
+- Choose boring, proven patterns
+
+### Complexity Triggers
+Only add complexity with:
+- Performance data showing current solution too slow
+- Concrete scale requirements (>1000 users, >100MB data)
+- Multiple proven use cases requiring abstraction
+
+### Clear References
+- Use `file.ts:42` format for code locations
+- Reference specs as `specs/auth/spec.md`
+- Link related changes and PRs
+
+### Capability Naming
+- Use verb-noun: `user-auth`, `payment-capture`
+- Single purpose per capability
+- 10-minute understandability rule
+- Split if description needs "AND"
+
+### Change ID Naming
+- Use kebab-case, short and descriptive: `add-two-factor-auth`
+- Prefer verb-led prefixes: `add-`, `update-`, `remove-`, `refactor-`
+- Ensure uniqueness; if taken, append `-2`, `-3`, etc.
+
+## Tool Selection Guide
+
+| Task | Tool | Why |
+|------|------|-----|
+| Find files by pattern | Glob | Fast pattern matching |
+| Search code content | Grep | Optimized regex search |
+| Read specific files | Read | Direct file access |
+| Explore unknown scope | Task | Multi-step investigation |
+
+## Error Recovery
+
+### Change Conflicts
+1. Run `openspec list` to see active changes
+2. Check for overlapping specs
+3. Coordinate with change owners
+4. Consider combining proposals
+
+### Validation Failures
+1. Run with `--strict` flag
+2. Check JSON output for details
+3. Verify spec file format
+4. Ensure scenarios properly formatted
+
+### Missing Context
+1. Read project.md first
+2. Check related specs
+3. Review recent archives
+4. Ask for clarification
+
+## Quick Reference
+
+### Stage Indicators
+- `changes/` - Proposed, not yet built
+- `specs/` - Built and deployed
+- `archive/` - Completed changes
+
+### File Purposes
+- `proposal.md` - Why and what
+- `tasks.md` - Implementation steps
+- `design.md` - Technical decisions
+- `spec.md` - Requirements and behavior
+
+### CLI Essentials
+```bash
+openspec list              # What's in progress?
+openspec show [item]       # View details
+openspec diff [change]     # What's changing?
+openspec validate --strict # Is it correct?
+openspec archive [change]  # Mark complete
+```
+
+Remember: Specs are truth. Changes are proposals. Keep them in sync.

-# OpenSpec Instructions
-
-This document provides instructions for AI coding assistants on how to use OpenSpec conventions for spec-driven development. Follow these rules precisely when working on OpenSpec-enabled projects.
-
-## Core Principle
-
-OpenSpec is an AI-native system for change-driven development where:
-- **Specs** (`specs/`) reflect what IS currently built and deployed
-- **Changes** (`changes/`) contain proposals for what SHOULD be changed
-- **AI drives the process** - You generate proposals, humans review and approve
-- **Specs are living documentation** - Always kept in sync with deployed code
-
-## Start Simple
-
-**Default to minimal implementations:**
-- New features should be <100 lines of code initially
-- Use the simplest solution that works
-- Avoid premature optimization (no caching, parallelization, or complex patterns without proven need)
-- Choose boring technology over cutting-edge solutions
-
-**Complexity triggers** - Only add complexity when you have:
-- **Performance data** showing current solution is too slow
-- **Scale requirements** with specific numbers (>1000 users, >100MB data)
-- **Multiple use cases** requiring the same abstraction
-- **Regulatory compliance** mandating specific patterns
-- **Security threats** that simple solutions cannot address
-
-When triggered, document the specific justification in your change proposal.

-
-### Capability Organization
-
-**Use capabilities, not features** - Each directory under `specs/` represents a single, focused responsibility:
-- **Verb-noun naming**: `user-auth`, `payment-capture`, `order-checkout`
-- **10-minute rule**: Each capability should be understandable in <10 minutes
-- **Single purpose**: If it needs "AND" to describe it, split it
-
-Examples:
-```
-✅ GOOD: user-auth, user-sessions, payment-capture, payment-refunds
-❌ BAD: users, payments, core, misc
-```
-
-## Key Behavioral Rules
-
-### 1. Always Start by Reading
-
-Before any task:
-1. **Read relevant specs** in `specs/[capability]/spec.md` to understand current state
-2. **Check pending changes** in `changes/` directory for potential conflicts
-3. **Read project.md** for project-specific conventions
-
-### 2. When to Create Change Proposals
-
-**ALWAYS create a change proposal for:**
-- New features or functionality
-- Breaking changes (API changes, schema updates)
-- Architecture changes or new patterns
-- Performance optimizations that change behavior
-- Security updates affecting auth/access patterns
-- Any change requiring multiple steps or affecting multiple systems
-
-**SKIP proposals for:**
-- Bug fixes that restore intended behavior
-- Typos, formatting, or comment updates
-- Dependency updates (unless breaking)
-- Configuration or environment variable changes
-- Adding tests for existing behavior
-- Documentation fixes
-
-**Complexity assessment:**
-- If your solution requires >100 lines of new code, justify the complexity
-- If adding dependencies, frameworks, or architectural patterns, document why simpler alternatives won't work
-- Default to single-file implementations until proven insufficient
-
-### 3. Delta-Based Change Format
-
-Changes use a delta format with clear sections:
-
-```markdown
-## ADDED Requirements
-### Requirement: New Feature
-[Complete requirement content in structured format]
-
-## MODIFIED Requirements  
-### Requirement: Existing Feature
-[Complete modified requirement (header must match current spec)]
-
-## REMOVED Requirements
-### Requirement: Old Feature
-**Reason for removal**: [Why removing]
-**Migration path**: [How to handle existing usage]
-
-## RENAMED Requirements
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-Key rules:
-- Headers are matched using `normalize(header) = trim(header)`
-- Include complete requirements (not diffs)
-- Use standard symbols in CLI output: + (added), ~ (modified), - (removed), → (renamed)
-
-### 4. Creating a Change Proposal
-
-When a user requests a significant change:
-
-```bash
-# 1. Create the change directory
-openspec/changes/[descriptive-name]/
-
-# 2. Generate proposal.md with all context
-## Why
-[1-2 sentences on the problem/opportunity]
-
-## What Changes  
-[Bullet list of changes, including breaking changes]
-
-## Impact
-- Affected specs: [list capabilities that will change]
-- Affected code: [list key files/systems]
-
-# 3. Create delta specs for ALL affected capabilities
-# - Store only the changes (not complete future state)
-# - Use sections: ## ADDED, ## MODIFIED, ## REMOVED, ## RENAMED
-# - Include complete requirements in their final form
-# Example spec.md content:
-#   ## ADDED Requirements
-#   ### Requirement: Password Reset
-#   Users SHALL be able to reset passwords via email...
-#   
-#   ## MODIFIED Requirements
-#   ### Requirement: User Authentication
-#   [Complete modified requirement with new password reset hook]
-specs/
-└── [capability]/
-    └── spec.md  # Contains delta sections
-
-# 4. Create tasks.md with implementation steps
-## 1. [Task Group]
-- [ ] 1.1 [Specific task]
-- [ ] 1.2 [Specific task]
-
-# 5. For complex changes, add design.md
-[Technical decisions and trade-offs]
-```
-
-### 5. The Change Lifecycle
-
-1. **Propose** → Create change directory with delta-based documentation
-2. **Review** → User reviews and approves the proposal
-3. **Implement** → Follow the approved tasks.md (can be multiple PRs)
-4. **Deploy** → User confirms deployment
-5. **Update Specs** → Apply deltas to sync specs/ with new reality (IF the change affects system capabilities)
-6. **Archive** → Move to `changes/archive/YYYY-MM-DD-[name]/`
-
-### 6. Implementing Changes
-
-When implementing an approved change:
-1. Follow the tasks.md checklist exactly
-2. **Mark completed tasks** in tasks.md as you finish them (e.g., `- [x] 1.1 Task completed`)
-3. Ensure code matches the proposed behavior
-4. Update any affected tests
-5. **Keep change in `changes/` directory** - do NOT archive in implementation PR
-
-**Multiple Implementation PRs:**
-- Changes can be implemented across multiple PRs
-- Each PR should update tasks.md to mark what was completed
-- Different developers can work on different task groups
-- Example: PR #1 completes tasks 1.1-1.3, PR #2 completes tasks 2.1-2.4
-
-### 7. Updating Specs and Archiving After Deployment
-
-**Create a separate PR after deployment** that:
-1. Moves change to `changes/archive/YYYY-MM-DD-[name]/`
-2. Updates relevant files in `specs/` to reflect new reality (if needed)
-3. If design.md exists, incorporates proven patterns into `specs/[capability]/design.md`
-
-This ensures changes are only archived when truly complete and deployed.
-
-### 8. Types of Changes That Don't Require Specs
-
-Some changes only affect development infrastructure and don't need specs:
-- Initial project setup (package.json, tsconfig.json, etc.)
-- Development tooling changes (linters, formatters, build tools)
-- CI/CD configuration
-- Development dependencies
-
-For these changes:
-1. Implement → Deploy → Mark tasks complete → Archive
-2. Skip the "Update Specs" step entirely
-
-### What Deserves a Spec?
-
-Ask yourself:
-- Is this a system capability that users or other systems interact with?
-- Does it have ongoing behavior that needs documentation?
-- Would a new developer need to understand this to work with the system?
-
-If NO to all → No spec needed (likely just tooling/infrastructure)
-
-## Understanding Specs vs Code
-
-### Specs Document WHAT and WHY
-```markdown
-# Authentication Spec
-
-Users SHALL authenticate with email and password.
-
-WHEN credentials are valid THEN issue JWT token.
-WHEN credentials are invalid THEN return generic error.
-
-WHY: Prevent user enumeration attacks.
-```
-
-### Code Documents HOW
-```javascript
-// Implementation details
-const user = await db.users.findOne({ email });
-const valid = await bcrypt.compare(password, user.hashedPassword);
-```
-
-**Key Distinction**: Specs capture intent, constraints, and decisions that aren't obvious from code.
-
-## Common Scenarios
-
-### New Feature Request
-```
-User: "Add password reset functionality"
-
-You should:
-1. Read specs/user-auth/spec.md
-2. Check changes/ for pending auth changes
-3. Create changes/add-password-reset/ with:
-   - proposal.md describing the change
-   - specs/user-auth/spec.md with:
-     ## ADDED Requirements
-     ### Requirement: Password Reset
-     [Complete requirement for password reset]
-     
-     ## MODIFIED Requirements
-     ### Requirement: User Authentication
-     [Updated to integrate with password reset]
-4. Wait for approval before implementing
-```
-
-### Bug Fix
-```
-User: "Getting null pointer error when bio is empty"
-
-You should:
-1. Check if spec says bios are optional
-2. If yes → Fix directly (it's a bug)
-3. If no → Create change proposal (it's a behavior change)
-```
-
-### Infrastructure Setup
-```
-User: "Initialize TypeScript project"
-
-You should:
-1. Create change proposal for TypeScript setup
-2. Implement configuration files (PR #1)
-3. Mark tasks complete in tasks.md
-4. After deployment, create separate PR to archive
-   (no specs update needed - this is tooling, not a capability)
-```
-
-## Summary Workflow
-
-1. **Receive request** → Determine if it needs a change proposal
-2. **Read current state** → Check specs and pending changes
-3. **Create proposal** → Generate complete change documentation
-4. **Get approval** → User reviews the proposal
-5. **Implement** → Follow approved tasks, mark completed items in tasks.md
-6. **Deploy** → User deploys the implementation
-7. **Archive PR** → Create separate PR to:
-   - Move change to archive
-   - Update specs if needed
-   - Mark change as complete
-
-## PR Workflow Examples
-
-### Single Developer, Simple Change
-```
-PR #1: Implementation
-- Implement all tasks
-- Update tasks.md marking items complete
-- Get merged and deployed
-
-PR #2: Archive (after deployment)
-- Move changes/feature-x/ → changes/archive/2025-01-15-feature-x/
-- Update specs if needed
-```
-
-### Multiple Developers, Complex Change
-```
-PR #1: Alice implements auth components
-- Complete tasks 1.1, 1.2, 1.3
-- Update tasks.md marking these complete
-
-PR #2: Bob implements UI components  
-- Complete tasks 2.1, 2.2
-- Update tasks.md marking these complete
-
-PR #3: Alice fixes integration issues
-- Complete remaining task 1.4
-- Update tasks.md
-
-[Deploy all changes]
-
-PR #4: Archive
-- Move to archive with deployment date
-- Update specs to reflect new auth flow
-```
-
-### Key Rules
-- **Never archive in implementation PRs** - changes aren't done until deployed
-- **Always update tasks.md** - shows accurate progress
-- **One archive PR per change** - clear completion boundary
-- **Archive PR includes spec updates** - keeps specs current
-
-## Capability Organization Best Practices
-
-### Naming Capabilities
-- Use **verb-noun** patterns: `user-auth`, `payment-capture`, `order-checkout`
-- Be specific: `payment-capture` not just `payments`
-- Keep flat: Avoid nesting capabilities within capabilities
-- Singular focus: If you need "AND" to describe it, split it
-
-### When to Split Capabilities
-Split when you have:
-- Multiple unrelated API endpoints
-- Different user personas or actors
-- Separate deployment considerations
-- Independent evolution paths
-
-#### Capability Boundary Guidelines
-- Would you import these separately? → Separate capabilities
-- Different deployment cadence? → Separate capabilities
-- Different teams own them? → Separate capabilities
-- Shared data models are OK, shared business logic means combine
-
-Examples:
-- user-auth (login/logout) vs user-sessions (token management) → SEPARATE
-- payment-capture vs payment-refunds → SEPARATE (different workflows)
-- user-profile vs user-settings → COMBINE (same data model, same owner)
-
-### Cross-Cutting Concerns
-For system-wide policies (rate limiting, error handling, security), document them in:
-- `project.md` for project-wide conventions
-- Within relevant capability specs where they apply
-- Or create a dedicated capability if complex enough (e.g., `api-rate-limiting/`)
-
-### Examples of Well-Organized Capabilities
-```
-specs/
-├── user-auth/              # Login, logout, password reset
-├── user-sessions/          # Token management, refresh
-├── user-profile/           # Profile CRUD operations
-├── payment-capture/        # Processing payments
-├── payment-refunds/        # Handling refunds
-└── order-checkout/         # Checkout workflow
-```
-
-For detailed guidance, see the [Capability Organization Guide](../docs/capability-organization.md).
-
-## Common Scenarios and Clarifications
-
-### Decision Ambiguity: Bug vs Behavior Change
-
-When specs are missing or ambiguous:
-- If NO spec exists → Treat current code behavior as implicit spec, require proposal
-- If spec is VAGUE → Require proposal to clarify spec alongside fix
-- If code and spec DISAGREE → Spec is truth, code is buggy (fix without proposal)
-- If unsure → Default to creating a proposal (safer option)
-
-Example:
-```
-User: "The API returns 404 for missing users but should return 400"
-AI: Is this a bug (spec says 400) or behavior change (spec says 404)?
-```
-
-### When You Don't Know the Scope
-It's OK to explore first! Tell the user you need to investigate, then create an informed proposal.
-
-### Exploration Phase (When Needed)
-
-BEFORE creating proposal, you may need exploration when:
-- User request is vague or high-level
-- Multiple implementation approaches exist
-- Scope is unclear without seeing code
-
-Exploration checklist:
-1. Tell user you need to explore first
-2. Use Grep/Read to understand current state
-3. Create initial proposal based on findings
-4. Refine with user feedback
-
-Example:
-```
-User: "Add caching to improve performance"
-AI: "Let me explore the codebase to understand the current architecture and identify caching opportunities."
-[After exploration]
-AI: "Based on my analysis, I've identified three areas where caching would help. Here's my proposal..."
-```
-
-### When No Specs Exist
-Treat current code as implicit spec. Your proposal should document current state AND proposed changes.
-
-### When in Doubt
-Default to creating a proposal. It's easier to skip an unnecessary proposal than fix an undocumented change.
-
-### AI Workflow Adaptations
-
-Task tracking with OpenSpec:
-- Track exploration tasks separately from implementation
-- Document proposal creation steps as you go
-- Keep implementation tasks separate until proposal approved
-
-Parallel operations encouraged:
-- Read multiple specs simultaneously
-- Check multiple pending changes at once
-- Batch related searches for efficiency
-
-Progress communication:
-- "Exploring codebase to understand scope..."
-- "Creating proposal based on findings..."
-- "Implementing approved changes..."
-
-### For AI Assistants
-- **Bias toward simplicity** - Propose the minimal solution that works
-- Use your exploration tools liberally before proposing
-- Batch operations for efficiency
-- Communicate your progress
-- It's OK to revise proposals based on discoveries
-- **Question complexity** - If your solution feels complex, simplify first
-
-## Edge Case Handling
-
-### Multi-Capability Changes
-Create ONE proposal that:
-- Lists all affected capabilities
-- Shows changes per capability
-- Has unified task list
-- Gets approved as a whole
-
-### Outdated Specs
-If specs clearly outdated:
-1. Create proposal to update specs to match reality
-2. Implement new feature in separate proposal
-3. OR combine both in one proposal with clear sections
-
-### Emergency Hotfixes
-For critical production issues:
-1. Announce: "This is an emergency fix"
-2. Implement fix immediately
-3. Create retroactive proposal
-4. Update specs after deployment
-5. Tag with [EMERGENCY] in archive
-
-### Pure Refactoring
-No proposal needed for:
-- Code formatting/style
-- Internal refactoring (same API)
-- Performance optimization (same behavior)
-- Adding types to untyped code
-
-Proposal REQUIRED for:
-- API changes (even if compatible)
-- Database schema changes
-- Architecture changes
-- New dependencies
-
-### Observability Additions
-No proposal needed for:
-- Adding log statements
-- New metrics/traces
-- Debugging additions
-- Error tracking
-
-Proposal REQUIRED if:
-- Changes log format/structure
-- Adds new monitoring service
-- Changes what's logged (privacy)
-
-## Remember
-
-- You are the process driver - automate documentation burden
-- Specs must always reflect deployed reality
-- Changes are proposed, not imposed
-- Impact analysis prevents surprises
-- Simplicity is the power - just markdown files, minimal solutions
-- Start simple, add complexity only when justified
-
-By following these conventions, you enable true spec-driven development where documentation stays current, changes are traceable, and evolution is intentional.

+# Add AGENTS.md Standard Support To Init/Update
+
+## Summary
+- Teach `openspec init` to manage a root-level `AGENTS.md` file using the same marker system as `CLAUDE.md`.
+- Allow `openspec update` to refresh or scaffold that root `AGENTS.md` so AGENTS-compatible tools always receive current instructions.
+- Keep the existing `openspec/AGENTS.md` template as the canonical source while ensuring assistants that read `AGENTS.md` opt-in instructions get the latest guidance automatically.
+
+## Motivation
+The README now points teams to AGENTS.md-compatible assistants, but the CLI only manages `CLAUDE.md`. Projects must hand-roll a root `AGENTS.md` file to benefit from the standard, and updates will drift unless maintainers remember to copy content manually. Extending `init` and `update` closes that gap so OpenSpec actually delivers on the promise of first-class AGENTS support.
+
+## Proposal
+1. Extend the `openspec init` selection flow with an "AGENTS.md standard" option that creates or refreshes a root `AGENTS.md` file wrapped in OpenSpec markers, mirroring the existing CLAUDE integration.
+2. When generating the file, pull the managed content from the same template used in `openspec/AGENTS.md`, ensuring both locations stay in sync.
+3. Update `openspec update` so it always refreshes the root `AGENTS.md` (creating it if missing) alongside `openspec/AGENTS.md` and any other configured assistants.
+4. Document the new behavior in CLI specs and verify marker handling (no duplicates, preserve user content outside the block) with tests for both commands.
+
+## Out of Scope
+- Adding additional AGENTS-specific prompts or workflows beyond the shared instructions block.
+- Non-interactive flags or bulk configuration for multiple standards in one run.
+- Broader restructuring of how templates are stored or loaded.
+
+## Risks & Mitigations
+- **Risk:** Accidentally overwriting user-edited content surrounding the managed block.
+  - **Mitigation:** Reuse the existing marker-update helper shared with `CLAUDE.md`, and add tests that cover files containing custom text before and after the block.
+- **Risk:** Divergence between `openspec/AGENTS.md` and the root file.
+  - **Mitigation:** Source the root file content from the canonical template rather than duplicating strings inline.
+- **Risk:** Confusion about when the file is created.
+  - **Mitigation:** Log creation vs update, and ensure help text references the AGENTS option during `init`.

+
+#### Scenario: Managing content with markers
+
+- **WHEN** using the marker system
+- **THEN** use `<!-- OPENSPEC:START -->` to mark the beginning of managed content
+- **AND** use `<!-- OPENSPEC:END -->` to mark the end of managed content
+- **AND** allow OpenSpec to update its content without affecting user customizations
+- **AND** preserve all content outside the markers intact

+# Allow Additional AI Tool Initialization After Setup
+
+## Summary
+- Let `openspec init` configure new AI coding tools for projects that already contain an OpenSpec structure.
+- Keep the initialization flow safe by skipping structure creation and only generating files for tools the user explicitly selects.
+- Provide clear feedback so users know which tool files were added versus already present.
+
+## Motivation
+Today `openspec init` exits with an error once an `openspec/` directory exists. That protects the directory layout, but it blocks
+teams that start with one assistant (for example, Claude Code) and later want to add another such as Cursor. They have to create
+those files by hand or rerun `init` in a clean clone, which undermines the "easy onboarding" promise. Letting the command extend
+an existing installation keeps the workflow consistent and avoids manual file management.
+
+## Proposal
+1. Detect an existing OpenSpec structure at the start of `openspec init` and branch into an "extend" mode instead of exiting.
+   - Announce that the base structure already exists and that the command will only manage AI tool configuration files.
+   - Keep the existing guard for directories or files we must not overwrite.
+2. Present the usual AI tool selection prompt even in extend mode, showing which tools are already configured.
+   - Skip disabled options that remain "coming soon".
+   - Mark already configured tools as such so users know whether selecting them will refresh or add files.
+3. When the user selects additional tools, generate the same initialization files that a fresh run would create (e.g., Cursor
+   workspace files) while leaving untouched tools intact apart from marker-managed sections.
+   - Do nothing when the user selects no new tools and keep the previous error messaging to avoid silently succeeding.
+4. Summarize the outcome (created, refreshed, skipped) before exiting with code 0 when work was performed.
+   - Include friendly guidance that future updates to shared content still come from `openspec update`.
+
+## Out of Scope
+- Changing how `openspec update` discovers or updates AI tool files.
+- Supporting brand-new AI tools beyond those already wired into the CLI.
+- Adding non-interactive flags for selecting multiple tools in one run (follow-up if needed).
+
+## Risks & Mitigations
+- **User confusion about extend mode** → Explicitly log what will happen before prompting and summarise results afterward.
+- **Accidental overwrites** → Continue using marker-based updates and skip files unless the user chooses that tool.
+- **Inconsistent state if init fails mid-run** → Reuse existing rollback/transaction logic so partial writes clean up.

+- **THEN** display a categorized summary of tools that were created, refreshed, or skipped (including already-configured skips)
+- **AND** personalize the "Next steps" header using the names of the selected tools, defaulting to a generic label when none remain
+
+### Requirement: Exit Code Adjustments
+`openspec init` SHALL treat extend mode with no selected tools as a guarded error.

+# Add Slash Command Support for Coding Agents
+
+## Summary
+- Enable OpenSpec to generate and update custom slash commands for supported coding agents (Claude Code and Cursor).
+- Provide three slash commands aligned with OpenSpec's workflow: proposal (start a change proposal), apply (implement), and archive.
+- Share slash command templating between agents to make future extensions simple.
+
+## Motivation
+Developers use different coding agents and editors. Having consistent slash commands across tools for the OpenSpec workflow reduces friction and ensures a standard way to trigger the workflow. Supporting both Claude Code and Cursor now lays a foundation for future agents that introduce slash command features.
+
+## Proposal
+1. During `openspec init`, when a user selects a supported tool, generate slash command configuration for three OpenSpec workflow stages:
+   - Claude (namespaced): `/openspec/proposal`, `/openspec/apply`, `/openspec/archive`.
+   - Cursor (flat, prefixed): `/openspec-proposal`, `/openspec-apply`, `/openspec-archive`.
+   - Semantics:
+     - Create – scaffold a change (ID, `proposal.md`, `tasks.md`, delta specs); validate strictly.
+     - Apply – implement an approved change; complete tasks; validate strictly.
+     - Archive – archive after deployment; update specs if needed.
+   - Each command file MUST embed concise, step-by-step instructions sourced from `openspec/README.md` (see Template Content section).
+2. Store slash command files per tool:
+   - Claude Code: `.claude/commands/openspec/{proposal,apply,archive}.md`
+   - Cursor: `.cursor/commands/{openspec-proposal,openspec-apply,openspec-archive}.md`
+   - Ensure nested directories are created.
+3. Command file format and metadata:
+   - Use Markdown with optional YAML frontmatter for tool metadata (name/title, description, category/tags) when supported by the tool.
+   - Place OpenSpec markers around the body only, never inside frontmatter.
+   - Keep the visible slash name, file name, and any frontmatter `name`/`id` consistently aligned (e.g., `proposal`, `openspec-proposal`).
+   - Namespacing: categorize these under “OpenSpec” and prefer unique IDs (e.g., `openspec-proposal`) to avoid collisions.
+4. Centralize templates: define command bodies once and reuse across tools; apply minimal per-tool wrappers (frontmatter, categories, filenames).
+5. During `openspec update`, refresh only existing slash command files (per-file basis) within markers; do not create missing files or new tools.
+
+## Design Ideas
+- Introduce `SlashCommandConfigurator` to manage multiple files per tool.
+  - Expose targets rather than a single `configFileName` (e.g., `getTargets(): Array<{ path: string; kind: 'slash'; id: string }>`).
+  - Provide `generateAll(projectPath, openspecDir)` for init and `updateExisting(projectPath, openspecDir)` for update.
+- Per-tool adapters add only frontmatter and pathing; bodies come from shared templates.
+- Templates live in `TemplateManager` with helpers that extract concise, authoritative snippets from `openspec/README.md`.
+- Update flow logs per-file results so users see exactly which slash files were refreshed.
+
+### Marker Placement
+- Markers MUST wrap only the Markdown body contents:
+  - Frontmatter (if present) goes first.
+  - Then `<!-- OPENSPEC:START -->` … body … `<!-- OPENSPEC:END -->`.
+  - Avoid inserting markers into the YAML block to prevent parse errors.
+
+### Idempotency and Creation Rules
+- `init`: create all three files for the chosen tool(s) once; subsequent `init` runs are no-ops for existing files.
+- `update`: refresh only files that exist; skip missing ones without creating new files.
+- Directory creation for `.claude/commands/openspec/` and `.cursor/commands/` is the configurator’s responsibility.
+
+### Command Naming & UX
+- Claude Code: use namespacing in the slash itself for readability and grouping: `/openspec/proposal`, `/openspec/apply`, `/openspec/archive`.
+- Cursor: use flat names with an `openspec-` prefix: `/openspec-proposal`, `/openspec-apply`, `/openspec-archive`. Group via `category: OpenSpec` when supported.
+- Consistency: align file names, visible slash names, and any frontmatter `id` (e.g., `id: openspec-apply`).
+- Migration: do not rename existing commands during `update`; apply new naming only on `init` (or via an explicit migrate step).
+
+## Open Questions
+- Validate exact metadata/frontmatter supported by each tool version; if unsupported, omit frontmatter and ship Markdown body only.
+- Confirm the final Cursor command file location for the targeted versions; fall back to Markdown-only if Cursor does not parse frontmatter.
+- Evaluate additional commands beyond the initial three (e.g., `/show-change`, `/validate-all`) based on user demand.
+
+## Alternatives
+- Hard-code slash command text per tool (rejected: duplicates content; increases maintenance).
+- Delay Cursor support until its config stabilizes (partial accept): gate Cursor behind a feature flag until verified in real environments.
+
+## Risks
+- Tool configuration formats may change, requiring updates to wrappers/frontmatter.
+- Incorrect paths or categories can hide commands; add path existence checks and clear logging.
+- Marker misuse (inside frontmatter) can break parsing; enforce placement rules in tests.
+
+## Future Work
+- Support additional editors/agents that expose slash command APIs.
+- Allow users to customize command names and categories during `openspec init`.
+- Provide a dedicated command to regenerate slash commands without running full `update`.
+
+## File Format Examples
+The following examples illustrate expected structure. If a tool does not support frontmatter, omit the YAML block and keep only the markers + body.
+
+### Claude Code: `.claude/commands/openspec/proposal.md`
+```markdown
+---
+name: OpenSpec: Proposal
+description: Scaffold a new OpenSpec change and validate strictly.
+category: OpenSpec
+tags: [openspec, change]
+---
+<!-- OPENSPEC:START -->
+...command body from shared template...
+<!-- OPENSPEC:END -->
+```
+
+Slash invocation: `/openspec/proposal` (namespaced)
+
+### Cursor: `.cursor/commands/openspec-proposal.md`
+```markdown
+---
+name: /openspec-proposal
+id: openspec-proposal
+category: OpenSpec
+description: Scaffold a new OpenSpec change and validate strictly.
+---
+<!-- OPENSPEC:START -->
+...command body from shared template...
+<!-- OPENSPEC:END -->
+```
+
+Slash invocation: `/openspec-proposal` (flat, prefixed)
+
+## Template Content
+Templates should be brief, actionable, and sourced from `openspec/README.md` to avoid duplication. Each command body includes:
+- Guardrails: ask 1–2 clarifying questions if needed; follow minimal-complexity rules; use `pnpm` for Node projects.
+- Step list tailored to the workflow stage (proposal, apply, archive), including strict validation commands.
+- Pointers to `openspec show`, `openspec list`, and troubleshooting tips when validation fails.
+
+## Testing Strategy
+- Golden snapshots for generated files per tool (frontmatter + markers + body).
+- Partial presence tests: if 1–2 files exist, `update` only refreshes those and does not create missing ones.
+- Marker placement tests: ensure markers never appear inside frontmatter; cover missing/duplicated marker recovery behavior.
+- Logging tests: `update` reports per-file updates for slash commands.

+# Implementation Tasks — Add Interactive Show Command
+
+## Goals
+- Add a top-level `show` command with intelligent selection and type detection.
+- Add interactive selection to `change show` and `spec show` when no ID is provided.
+- Preserve raw-first output behavior and existing JSON formats/filters.
+- Respect `--no-interactive` and `OPEN_SPEC_INTERACTIVE=0` consistently.
+
+---
+
+## 1) CLI wiring
+- [x] In `src/cli/index.ts` add a top-level command: `program.command('show [item-name]')`
+  - Options:
+    - `--json`
+    - `--type <type>` where `<type>` is `change|spec`
+    - `--no-interactive`
+    - Allow passing-through type-specific flags using `.allowUnknownOption(true)` so the top-level can forward flags to the underlying type handler.
+  - Action: instantiate `new ShowCommand().execute(itemName, options)`.
+- [x] Update `change show` subcommand to accept `--no-interactive` and pass it to `ChangeCommand.show(...)`.
+- [x] Change `spec show` subcommand to accept optional ID (`show [spec-id]`), add `--no-interactive`, and pass to spec show implementation.
+
+Acceptance:
+- `openspec show` exists and prints a helpful hint in non-interactive contexts when no args.
+- Unknown flags for other types do not crash parsing; they are warned/ignored appropriately.
+
+---
+
+## 2) New module: `src/commands/show.ts`
+- [x] Create `ShowCommand` with:
+  - `execute(itemName?: string, options?: { json?: boolean; type?: string; noInteractive?: boolean; [k: string]: any })`
+  - Interactive path when `!itemName` and interactive is enabled:
+    - Prompt: "What would you like to show?" → `change` or `spec`.
+    - Load available IDs for the chosen type and prompt selection.
+    - Delegate to type-specific show implementation.
+  - Non-interactive path when `!itemName`:
+    - Print hint with examples:
+      - `openspec show <item>`
+      - `openspec change show`
+      - `openspec spec show`
+    - Exit with code 1.
+  - Direct item path when `itemName` is provided:
+    - Type override via `--type` takes precedence.
+    - Otherwise detect using `getActiveChangeIds()` and `getSpecIds()`.
+    - If ambiguous and no override: print error + suggestion to pass `--type` or use subcommands; exit code 1.
+    - If unknown: print not-found with nearest-match suggestions; exit code 1.
+    - On success: delegate to type-specific show.
+- [x] Flag scoping and pass-through:
+  - Common: `--json` → forwarded to both types.
+  - Change-only: `--deltas-only`, `--requirements-only` (deprecated alias).
+  - Spec-only: `--requirements`, `--no-scenarios`, `-r/--requirement`.
+  - Warn and ignore irrelevant flags for the resolved type.
+
+Acceptance:
+- `openspec show <change-id> --json --deltas-only` matches `openspec change show <id> --json --deltas-only` output.
+- `openspec show <spec-id> --json --requirements` matches `openspec spec show <id> --json --requirements` output.
+- Ambiguity and not-found behaviors match the `cli-show` spec.
+
+---
+
+## 3) Refactor spec show into reusable API
+- [x] In `src/commands/spec.ts`, extract show logic into an exported `SpecCommand` with `show(specId?: string, options?: { json?: boolean; requirements?: boolean; scenarios?: boolean; requirement?: string; noInteractive?: boolean })`.
+  - Reuse current helpers (`parseSpecFromFile`, `filterSpec`, raw-first printing).
+  - Keep `registerSpecCommand` but delegate to `new SpecCommand().show(...)`.
+- [x] Update CLI spec show subcommand to optional arg and interactive behavior (see section 4).
+
+Acceptance:
+- Existing `spec show` tests continue to pass.
+- New `SpecCommand.show` can be called from `ShowCommand`.
+
+---
+
+## 4) Backwards-compatible interactive in subcommands
+- [x] `src/commands/change.ts` → extend `show(changeName?: string, options?: { json?: boolean; requirementsOnly?: boolean; deltasOnly?: boolean; noInteractive?: boolean })`:
+  - When `!changeName` and interactive enabled: prompt from `getActiveChangeIds()` and show the selected change.
+  - Non-interactive fallback: keep current behavior (print available IDs + `openspec change list` hint, set `process.exitCode = 1`).
+- [x] `src/commands/spec.ts` → `SpecCommand.show` as above:
+  - When `!specId` and interactive enabled: prompt from `getSpecIds()` and show the selected spec.
+  - Non-interactive fallback: print the same error as existing behavior for missing `<spec-id>` and set non-zero exit code.
+
+Acceptance:
+- `openspec change show` in non-interactive prints list hint and exits non-zero.
+- `openspec spec show` in non-interactive prints missing-arg error and exits non-zero.
+
+---
+
+## 5) Shared utilities
+- [x] Extract `nearestMatches` and `levenshtein` from `src/commands/validate.ts` into `src/utils/match.ts` (exported helpers).
+- [x] Update `ValidateCommand` and new `ShowCommand` to import from `utils/match`.
+
+Acceptance:
+- Build succeeds with shared helpers and no duplication.
+
+---
+
+## 6) Hints, warnings, and messages
+- [x] Top-level `show` hint (non-interactive no-arg):
+  - Lines include: `openspec show <item>`, `openspec change show`, `openspec spec show`, and "Or run in an interactive terminal.".
+- [x] Ambiguity message suggests `--type change|spec` and the subcommands.
+- [x] Not-found suggests nearest matches (up to 5).
+- [x] Irrelevant flag warnings for the resolved type (printed to stderr, no crash).
+
+Acceptance:
+- Messages match the `cli-show` spec wording intent and style used elsewhere.
+
+---
+
+## 7) Tests
+Add tests mirroring existing patterns (non-TTY simulation via `OPEN_SPEC_INTERACTIVE=0`).
+
+- [x] `test/commands/show.test.ts`
+  - Non-interactive, no arg → prints hint and exits non-zero.
+  - Direct item detection for change and for spec.
+  - Ambiguity case when both exist → error and suggestion for `--type`.
+  - Not-found case → nearest-match suggestions.
+  - Pass-through flags: change `--json --deltas-only`, spec `--json --requirements`.
+- [x] `test/commands/change.interactive-show.test.ts` (non-interactive fallback)
+  - Ensure `openspec change show` without args prints available IDs + list hint and non-zero exit.
+- [x] `test/commands/spec.interactive-show.test.ts` (non-interactive fallback)
+  - Ensure `openspec spec show` without args prints missing-arg error and non-zero exit.
+
+Acceptance:
+- All new tests pass after build; no regressions in existing tests.
+
+---
+
+## 8) Documentation (optional but recommended)
+- [x] Update `openspec/README.md` usage examples to include the new `show` command with type detection and flags.
+
+---
+
+## 9) Non-functional checks
+- [x] Run `pnpm build` and all tests (`pnpm test`).
+- [x] Ensure no linter/type errors and messages are consistent with existing style.
+
+---
+
+## Notes on consistency
+- Follow raw-first behavior for text output: passthrough file content with no formatting, mirroring current `change show` and `spec show`.
+- Reuse `isInteractive` and `item-discovery` helpers for consistent prompting behavior.
+- Keep JSON output shapes identical to current `ChangeCommand.show` and `spec show` outputs.

+# Design: Verb–Noun CLI Structure Adoption
+
+## Overview
+We will make verb commands (`list`, `show`, `validate`, `diff`, `archive`) the primary interface and keep noun commands (`spec`, `change`) as deprecated aliases for one release.
+
+## Decisions
+
+1. Keep routing centralized in `src/cli/index.ts`.
+2. Add `--specs`/`--changes` to `openspec list`, with `--changes` as default.
+3. Show deprecation warnings for `openspec change list` and, more generally, for any `openspec change ...` and `openspec spec ...` subcommands.
+4. Do not change `show`/`validate` behavior beyond help text; they already support `--type` for disambiguation.
+
+## Backward Compatibility
+All noun-based commands continue to work with clear deprecation warnings directing users to verb-first equivalents.
+
+## Out of Scope
+JSON output parity for `openspec list` across modes and `show --specs/--changes` discovery are follow-ups.

+# Change: Adopt Verb–Noun CLI Structure (Deprecate Noun-Based Commands)
+
+## Why
+
+Most widely used CLIs (git, docker, kubectl) start with an action (verb) followed by the object (noun). This matches how users think: “do X to Y”. Using verbs as top-level commands improves clarity, discoverability, and extensibility.
+
+## What Changes
+
+- Promote top-level verb commands as primary entry points: `list`, `show`, `validate`, `diff`, `archive`.
+- Deprecate noun-based top-level commands: `openspec spec ...` and `openspec change ...`.
+- Introduce consistent noun scoping via flags where applicable (e.g., `--changes`, `--specs`) and keep smart defaults.
+- Clarify disambiguation for `show` and `validate` when names collide.
+
+### Mappings (From → To)
+
+- **List**
+  - From: `openspec change list`
+  - To: `openspec list --changes` (default), or `openspec list --specs`
+
+- **Show**
+  - From: `openspec spec show <spec-id>` / `openspec change show <change-id>`
+  - To: `openspec show <item-id>` with auto-detect, use `--type spec|change` if ambiguous
+
+- **Validate**
+  - From: `openspec spec validate <spec-id>` / `openspec change validate <change-id>`
+  - To: `openspec validate <item-id> --type spec|change`, or bulk: `openspec validate --specs` / `--changes` / `--all`
+
+### Backward Compatibility
+
+- Keep `openspec spec` and `openspec change` available with deprecation warnings for one release cycle.
+- Update help text to point users to the verb–noun alternatives.
+
+## Impact
+
+- **Affected specs**:
+  - `cli-list`: Add support for `--specs` and explicit `--changes` (default remains changes)
+  - `openspec-conventions`: Add explicit requirement establishing verb–noun CLI design and deprecation guidance
+- **Affected code**:
+  - `src/cli/index.ts`: Un-deprecate top-level `list`; mark `change list` as deprecated; ensure help text and warnings align
+  - `src/core/list.ts`: Support listing specs via `--specs` and default to changes; shared output shape
+  - Optional follow-ups: tighten `show`/`validate` help and ambiguity handling
+
+## Explicit Changes
+
+**CLI Design**
+- From: Mixed model with nouns (`spec`, `change`) and some top-level verbs; `openspec list` currently deprecated
+- To: Verbs as primary: `openspec list|show|validate|diff|archive`; nouns scoped via flags or item ids; noun commands deprecated
+- Reason: Align with common CLIs; improve UX; simpler mental model
+- Impact: Non-breaking with deprecation period; users migrate incrementally
+
+**Listing Behavior**
+- From: `openspec change list` (primary), `openspec list` (deprecated)
+- To: `openspec list` as primary, defaulting to `--changes`; add `--specs` to list specs
+- Reason: Consistent verb–noun style; better discoverability
+- Impact: New option; preserves existing behavior via default
+
+## Rollout and Deprecation Policy
+
+- Show deprecation warnings on noun-based commands for one release.
+- Document new usage in `openspec/README.md` and CLI help.
+- After one release, consider removing noun-based commands, or keep as thin aliases without warnings.
+
+## Open Questions
+
+- Should `show` also accept `--changes`/`--specs` for discovery without an id? (Out of scope here; current auto-detect and `--type` remain.)

+# Delta: OpenSpec Conventions — Verb–Noun CLI Design
+
+## ADDED Requirements
+
+### Requirement: Verb–Noun CLI Command Structure
+OpenSpec CLI design SHALL use verbs as top-level commands with nouns provided as arguments or flags for scoping.
+
+#### Scenario: Verb-first command discovery
+- **WHEN** a user runs a command like `openspec list`
+- **THEN** the verb communicates the action clearly
+- **AND** nouns refine scope via flags or arguments (e.g., `--changes`, `--specs`)
+
+#### Scenario: Backward compatibility for noun commands
+- **WHEN** users run noun-prefixed commands such as `openspec spec ...` or `openspec change ...`
+- **THEN** the CLI SHALL continue to support them for at least one release
+- **AND** display a deprecation warning that points to verb-first alternatives
+
+#### Scenario: Disambiguation guidance
+- **WHEN** item names are ambiguous between changes and specs
+- **THEN** `openspec show` and `openspec validate` SHALL accept `--type spec|change`
+- **AND** the help text SHALL document this clearly

+## 3. Specs and Conventions
+- [x] 3.1 Update `openspec/specs/cli-list/spec.md` to document `--specs` (and default to changes)
+- [x] 3.2 Update `openspec/specs/openspec-conventions/spec.md` with a requirement for verb–noun CLI design and deprecation guidance

+# improve-validate-error-messages
+
+## Why
+
+Developers struggle to resolve validation failures because current errors lack actionable guidance. Common issues include: missing deltas, missing required sections, and misformatted scenarios that are silently ignored. Without clear remediation steps, users cannot quickly correct structure or formatting, leading to frustration and rework. Improving error messages with concrete fixes, file/section hints, and suggested commands will significantly reduce time-to-green and make OpenSpec more approachable.
+
+## What Changes
+
+- Validation errors SHALL include specific remediation steps (what to change and where).
+- "No deltas found" error SHALL guide users to create `specs/` with proper delta headers and suggest debug commands.
+- Missing required sections (Spec: Purpose/Requirements; Change: Why/What Changes) SHALL include expected header names and a minimal skeleton example.
+- Likely misformatted scenarios (bulleted WHEN/THEN/AND) SHALL emit a targeted warning explaining the `#### Scenario:` format and show a conversion template.
+- All reported issues SHALL include the source file path and structured location (e.g., `deltas[0].requirements[0]`).
+- Non-JSON output SHOULD end with a short "Next steps" footer when invalid.
+
+## Impact
+
+- Affected CLI: validate
+- Affected code:
+  - `src/commands/validate.ts`
+  - `src/core/validation/validator.ts`
+  - `src/core/validation/constants.ts`
+  - `src/core/parsers/*` (wrapping thrown errors with richer context)

+# Validate Command
+
+## ADDED Requirements
+
+### Requirement: Validation SHALL provide actionable remediation steps
+Validation output SHALL include specific guidance to fix each error, including expected structure, example headers, and suggested commands to verify fixes.
+
+#### Scenario: No deltas found in change
+- **WHEN** validating a change with zero parsed deltas
+- **THEN** show error "No deltas found" with guidance:
+  - Ensure `openspec/changes/{id}/specs/` exists with `.md` files
+  - Use delta headers: `## ADDED Requirements`, `## MODIFIED Requirements`, `## REMOVED Requirements`, `## RENAMED Requirements`
+  - Each requirement must include at least one `#### Scenario:` block
+  - Try: `openspec change show {id} --json --deltas-only` to inspect what was parsed
+
+#### Scenario: Missing required sections
+- **WHEN** a required section is missing
+- **THEN** the validator SHALL include expected header names and a minimal skeleton:
+  - For Spec: `## Purpose`, `## Requirements`
+  - For Change: `## Why`, `## What Changes`
+  - Show an example snippet of the missing section
+
+### Requirement: Validator SHALL detect likely misformatted scenarios and warn with a fix
+The validator SHALL recognize bulleted lines that look like scenarios (e.g., lines beginning with WHEN/THEN/AND) and emit a targeted warning with a conversion example to `#### Scenario:`.
+
+#### Scenario: Bulleted WHEN/THEN under a Requirement
+- **WHEN** bullets that start with WHEN/THEN/AND are found under a requirement without any `#### Scenario:` headers
+- **THEN** emit warning: "Scenarios must use '#### Scenario:' headers", and show a conversion template:
+```
+#### Scenario: Short name
+- **WHEN** ...
+- **THEN** ...
+- **AND** ...
+```
+
+### Requirement: All issues SHALL include file paths and structured locations
+Error, warning, and info messages SHALL include:
+- Source file path (`openspec/changes/{id}/proposal.md`, `.../specs/{cap}/spec.md`)
+- Structured path (e.g., `deltas[0].requirements[0].scenarios`)
+
+#### Scenario: Zod validation error
+- **WHEN** a schema validation fails
+- **THEN** the message SHALL include `file`, `path`, and a remediation hint if applicable
+
+### Requirement: Invalid results SHALL include a Next steps footer in human-readable output
+The CLI SHALL append a Next steps footer when the item is invalid and not using `--json`, including:
+- Summary line with counts
+- Top-3 guidance bullets (contextual to the most frequent or blocking errors)
+- A suggestion to re-run with `--json` and/or the debug command
+
+#### Scenario: Change invalid summary
+- **WHEN** a change validation fails
+- **THEN** print "Next steps" with 2-3 targeted bullets and suggest `openspec change show <id> --json --deltas-only`

+# Change: Add View Dashboard Command
+
+## Why
+
+Users need a quick, at-a-glance overview of their OpenSpec project status without running multiple commands. Currently, users must run `openspec list --changes` and `openspec list --specs` separately to understand the project state. A unified dashboard view would improve developer experience and provide immediate insight into project progress.
+
+## What Changes
+
+### Added `openspec view` Command
+
+The new command provides an interactive dashboard displaying:
+- Summary metrics (total specs, requirements, changes, task progress)
+- Active changes with visual progress bars
+- Completed changes
+- Specifications with requirement counts
+
+### Specifications Affected
+
+- **cli-view** (NEW): Complete specification for the view dashboard command
+
+## Implementation Details
+
+### File Structure
+- Created `/src/core/view.ts` implementing the `ViewCommand` class
+- Registered command in `/src/cli/index.ts`
+- Reuses existing utilities from `task-progress.ts` and `MarkdownParser`
+
+### Visual Design
+- Uses Unicode box drawing characters for borders
+- Color coding: cyan for specs, yellow for active, green for completed
+- Progress bars using filled (█) and empty (░) blocks
+- Clean alignment with proper padding
+
+### Technical Approach
+- Async data fetching from changes and specs directories
+- Parallel processing of specs and changes
+- Error handling for missing or invalid data
+- Maintains consistency with existing list command output

+
+#### Scenario: Mixed completion states
+
+- **WHEN** some changes are complete and others active
+- **THEN** system separates them into appropriate sections
+
+### Requirement: Specifications Display
+
+The dashboard SHALL display specifications sorted by requirement count.

+#### Scenario: Color coding
+
+- **WHEN** dashboard elements are displayed
+- **THEN** system uses cyan for specification items
+- **AND** yellow for active changes
+- **AND** green for completed items
+- **AND** dim gray for supplementary text
+
+#### Scenario: Progress bar rendering
+
+- **WHEN** displaying progress bars
+- **THEN** system uses filled blocks (█) for completed portions and light blocks (░) for remaining
+
+### Requirement: Error Handling
+
+The view command SHALL handle errors gracefully.
+
+#### Scenario: File system errors
+
+- **WHEN** file system operations fail
+- **THEN** system continues with available data and omits inaccessible items
+
+#### Scenario: Invalid data structures
+
+- **WHEN** specs or changes have invalid format

+# Change: Improve Deterministic Tests (Isolate From Repo State)
+
+## Problem
+
+Some unit tests (e.g., ChangeCommand.show/validate) read the live repository
+state via `process.cwd()` and `openspec/changes`. This makes outcomes depend on
+whatever directories happen to exist and the order returned by `fs.readdir`,
+causing flaky success/failure across environments.
+
+Symptoms observed:
+- Tests sometimes select a partial or unrelated change folder.
+- Failures like missing `proposal.md` when a stray change directory is picked.
+- Environment/sandbox differences alter `readdir` ordering and worker behavior.
+
+## Goals
+
+- Make tests deterministic and hermetic.
+- Remove dependence on real repo contents and directory ordering.
+- Keep runtime behavior unchanged for end users.
+
+## Non‑Goals
+
+- Introduce heavy frameworks or test harness complexity.
+- Redesign CLI behavior or change default paths for users.
+
+## Approach
+
+1) Test-local fixture root
+- Each suite that touches filesystem discovery creates a temporary directory:
+  - `openspec/changes/sample-change/proposal.md`
+  - `openspec/changes/sample-change/specs/sample/spec.md`
+- `beforeAll`: `process.chdir(tmpRoot)`; `afterAll`: restore original cwd.
+- Use a constant `changeName = 'sample-change'`; remove reliance on
+  `readdir` order.
+
+2) Optional thin DI for commands (minimal, if needed)
+- Allow `ChangeCommand` (and similar) to accept an optional `root` path
+  (default `process.cwd()`), used for path resolution.
+- Tests pass the temp root explicitly; production code remains unchanged.
+
+3) Harden discovery helpers (safe enhancement)
+- Update `getActiveChangeIds()`/`getActiveChanges()` to include only
+  directories containing `proposal.md` (and optionally at least one
+  `specs/*/spec.md`).
+- Prevents incomplete/stray change folders from being treated as active.
+
+## Rationale
+
+- Small, focused changes eliminate flakiness without altering user workflows.
+- Temporary fixtures are a well-understood testing pattern and keep tests fast.
+- Optional constructor root param is a minimal DI surface that avoids global
+  stubbing and keeps code simple.
+
+## Risks & Mitigations
+
+- Risk: Tests forget to restore `process.cwd()`.
+  - Mitigation: Add `afterAll` guard restoring cwd; reset `process.exitCode` in
+    `afterEach` where modified.
+- Risk: Behavior divergence if DI root is misused.
+  - Mitigation: Default to `process.cwd()`; only tests pass custom roots.
+
+## Acceptance Criteria
+
+- Tests that previously depended on repo state now:
+  - Create and use a temp fixture root.
+  - Do not read real `openspec/changes` during execution.
+  - Pass consistently regardless of directory order or stray folders.
+- No change to CLI behavior for end users (paths still default to cwd).
+
+## Rollout
+
+- Phase 1: Convert the suites that hit `ChangeCommand.show/validate` to
+  isolated fixtures; verify stability locally and in CI.
+- Phase 2: Apply the same pattern to any remaining suites that touch file
+  discovery (`list`, `show`, `validate`, `diff`).
+- Phase 3 (optional): Introduce the constructor `root` param and discovery
+  hardening, if Phase 1 alone isn’t sufficient.

+## Why
+The current `openspec init` flow assumes a single assistant selection and stops once an OpenSpec structure already exists. That makes onboarding feel rigid: teams cannot configure multiple tools in one pass, they do not learn which files were refreshed, and the success copy always references Claude even when other assistants are involved.
+
+## What Changes
+- Allow selecting multiple assistants during `openspec init`, including refreshing existing configurations in a single run.
+- Provide richer onboarding copy that summarizes which tool files were created or refreshed and guides users on next steps for each assistant.
+- Align generated AI-instruction content and specs so CLAUDE.md and AGENTS.md share the same OpenSpec guidance.
+- Update specs and tests to cover the multi-select prompt, improved summaries, and extend-mode coordination.
+
+## Impact
+- Specs: `cli-init`
+- Code: `src/core/init.ts`, `src/core/config.ts`, `src/core/templates/*`, `src/core/configurators/*`

+## MODIFIED Requirements
+### Requirement: AI Tool Configuration
+
+The command SHALL configure AI coding assistants with OpenSpec instructions based on user selection.
+
+#### Scenario: Prompting for AI tool selection
+
+- **WHEN** run interactively
+- **THEN** prompt the user with "Which AI tools do you use?" using a multi-select menu
+- **AND** list every available tool with a checkbox:
+  - Claude Code (creates or refreshes CLAUDE.md and slash commands)
+  - Cursor (creates or refreshes `.cursor/commands/*` slash commands)
+  - AGENTS.md standard (creates or refreshes AGENTS.md with OpenSpec markers)
+- **AND** show "(already configured)" beside tools whose managed files exist so users understand selections will refresh content
+- **AND** treat disabled tools as "coming soon" and keep them unselectable
+- **AND** allow confirming with Enter after selecting one or more tools
+
+### Requirement: AI Tool Configuration Details
+
+The command SHALL properly configure selected AI tools with OpenSpec-specific instructions using a marker system.
+
+#### Scenario: Configuring Claude Code
+
+- **WHEN** Claude Code is selected
+- **THEN** create or update `CLAUDE.md` in the project root directory (not inside openspec/)
+
+#### Scenario: Creating new CLAUDE.md
+
+- **WHEN** CLAUDE.md does not exist
+- **THEN** create new file with OpenSpec content wrapped in markers:
+```markdown
+<!-- OPENSPEC:START -->
+# OpenSpec Instructions
+
+Instructions for AI coding assistants using OpenSpec for spec-driven development.
+
+## TL;DR Quick Checklist
+- Search existing work: `openspec spec list --long`, `openspec list`
+- Decide scope: new capability vs modify existing capability
+- Pick a unique `change-id`: verb-led kebab-case (`add-`, `update-`, `remove-`, `refactor-`)
+- Scaffold: `proposal.md`, `tasks.md`, optional `design.md`, and spec deltas
+- Validate with `openspec validate [change-id] --strict`
+- Request approval before implementation
+<!-- OPENSPEC:END -->
+```
+
+#### Scenario: Updating existing CLAUDE.md
+
+- **WHEN** CLAUDE.md already exists
+- **THEN** preserve all existing content
+- **AND** insert OpenSpec content at the beginning of the file using markers
+- **AND** ensure markers don't duplicate if they already exist
+
+#### Scenario: Managing content with markers
+
+- **WHEN** using the marker system
+- **THEN** use `<!-- OPENSPEC:START -->` to mark the beginning of managed content
+- **AND** use `<!-- OPENSPEC:END -->` to mark the end of managed content
+- **AND** allow OpenSpec to update its content without affecting user customizations
+- **AND** preserve all content outside the markers intact
+
+### Requirement: Interactive Mode
+
+The command SHALL provide an interactive menu for AI tool selection with clear navigation instructions.
+
+#### Scenario: Displaying interactive menu
+
+- **WHEN** run
+- **THEN** prompt the user with: "Which AI tools do you use?"
+- **AND** show a checkbox-based multi-select menu with available tools (Claude Code, Cursor, AGENTS.md standard)
+- **AND** show disabled options as "coming soon" (not selectable)
+- **AND** display inline help indicating Space toggles selections and Enter confirms
+
+#### Scenario: Navigating the menu
+
+- **WHEN** the user is in the menu
+- **THEN** allow arrow keys to move between options
+- **AND** allow Spacebar to toggle the highlighted option
+- **AND** allow Enter key to confirm all current selections
+
+### Requirement: Success Output
+
+The command SHALL provide clear, actionable next steps upon successful initialization.
+
+#### Scenario: Displaying success message
+
+- **WHEN** initialization completes successfully
+- **THEN** display a success banner followed by actionable prompts tailored to the selected tools
+- **AND** summarize which assistant files were created versus refreshed (e.g., `CLAUDE.md (created)`, `.cursor/commands/openspec-apply.md (refreshed)`)
+- **AND** include copy-pasteable onboarding prompts for each configured assistant, replacing placeholder text ([YOUR FEATURE HERE]) with real guidance to customize
+- **AND** reference AGENTS.md-compatible assistants when no tool-specific file exists (e.g., when only AGENTS.md standard is selected)

+## Why
+Validation currently errors on changes without spec deltas, even when the change is intentionally proposal-only or tooling-only. This creates false negatives and noisy CI.
+
+## What Changes
+- Make change validation scope-aware: validate only artifacts that exist.
+- Only error on "No deltas found" if spec delta files exist but parse to zero deltas.
+- Keep archive stricter: if specs exist but parse to zero deltas, fail; allow `--skip-specs` for tooling-only changes.
+
+## Impact
+- Affected specs: cli-validate

+#### Scenario: No deltas found in change
+- **WHEN** validating a change that contains `specs/` with one or more `*/spec.md` files but the parser finds zero deltas
+- **THEN** show error "No deltas found" with guidance:
+  - Ensure `openspec/changes/{id}/specs/` has `.md` files that include delta headers
+  - Use delta headers: `## ADDED Requirements`, `## MODIFIED Requirements`, `## REMOVED Requirements`, `## RENAMED Requirements`
+  - Each requirement must include at least one `#### Scenario:` block

+# Remove Diff Command
+
+## Problem
+
+The `openspec diff` command adds unnecessary complexity to the OpenSpec CLI for several reasons:
+
+1. **Redundant functionality**: The `openspec show` command already provides comprehensive visualization of changes through structured JSON output and markdown rendering
+2. **Maintenance burden**: The diff command requires a separate dependency (jest-diff) and additional code complexity (~227 lines)
+3. **Limited value**: Developers can achieve better diff visualization using existing tools:
+   - Git diff for actual file changes
+   - The `show` command for structured change viewing
+   - Standard diff utilities for comparing spec files directly
+4. **Inconsistent with verb-noun pattern**: The command doesn't follow the preferred verb-first command structure that other commands are migrating to
+
+## Solution
+
+Remove the `openspec diff` command entirely and guide users to more appropriate alternatives:
+
+1. **For viewing change content**: Use `openspec show <change-name>` which provides:
+   - Structured JSON output with `--json` flag
+   - Markdown rendering for human-readable format
+   - Delta-only views with `--deltas-only` flag
+   - Full spec content visualization
+
+2. **For comparing files**: Use standard tools:
+   - `git diff` for version control comparisons
+   - System diff utilities for file-by-file comparisons
+   - IDE diff viewers for visual comparisons
+
+## Benefits
+
+- **Reduced complexity**: Removes ~227 lines of code and the jest-diff dependency
+- **Clearer user journey**: Directs users to the canonical `show` command for viewing changes
+- **Lower maintenance**: Fewer commands to maintain and test
+- **Better alignment**: Focuses on the core OpenSpec workflow without redundant features
+
+## Implementation
+
+### Files to Remove
+- `/src/core/diff.ts` - The entire diff command implementation
+- `/openspec/specs/cli-diff/spec.md` - The diff command specification
+
+### Files to Update
+- `/src/cli/index.ts` - Remove diff command registration (lines 8, 84-96)
+- `/package.json` - Remove jest-diff dependency
+- `/README.md` - Remove diff command documentation
+- `/openspec/README.md` - Remove diff command references
+- Various documentation files mentioning `openspec diff`
+
+### Migration Guide for Users
+
+Users currently using `openspec diff` should transition to:
+
+```bash
+# Before
+openspec diff add-feature
+
+# After - view the change proposal
+openspec show add-feature
+
+# After - view only the deltas
+openspec show add-feature --json --deltas-only
+
+# After - use git for file comparisons
+git diff openspec/specs openspec/changes/add-feature/specs
+```
+
+## Risks
+
+- **User disruption**: Existing users may have workflows depending on the diff command
+  - Mitigation: Provide clear migration guide and deprecation period
+  
+- **Loss of visual diff**: The colored, unified diff format will no longer be available
+  - Mitigation: Users can use git diff or other tools for visual comparisons
+
+## Success Metrics
+
+- Successful removal with no broken dependencies
+- Documentation updated to reflect the change
+- Tests passing without the diff command
+- Reduced package size from removing jest-diff dependency

+# Change: Sort Active Changes by Progress
+
+## Problem
+- The dashboard currently lists active changes in filesystem discovery order.
+- Users cannot quickly spot proposals that have not started or are nearly complete.
+- Inconsistent ordering between runs makes it harder to track progress when many changes exist.
+
+## Proposal
+1. Update the Active Changes list in the dashboard to sort by percentage of completion in ascending order so 0% items show first.
+2. When two changes share the same completion percentage, break ties deterministically by change identifier (alphabetical).
+
+## Benefits
+- Highlights work that has not started yet, enabling quicker prioritization.
+- Provides consistent ordering across machines and repeated runs.
+- Keeps the dashboard compact while communicating the most important status signal.
+
+## Risks & Mitigations
+- **Risk:** Sorting logic could regress rendering when progress data is missing.
+  - **Mitigation:** Treat missing progress as 0% so items still surface and document behavior in tests.
+- **Risk:** Additional sorting could impact performance for large change sets.
+  - **Mitigation:** The number of active changes is typically small; sorting a few entries is negligible.
+
+## Success Criteria
+- Dashboard output shows active changes ordered by ascending completion percentage with deterministic tie-breaking.
+- Unit coverage verifying the sort when percentages vary and when ties occur.

+# Design: Agent Instructions Update
+
+## Approach
+
+### Information Architecture
+- **Front-load critical information** - Three-stage workflow comes first
+- **Clear hierarchy** - Core Workflow → Quick Start → Commands → Details → Edge Cases
+- **50% length reduction** - Target ~285 lines from current ~575 lines
+- **Imperative mood** - "Create proposal" vs "You should create a proposal"
+- **Bullet points over paragraphs** - Scannable, concise information
+
+### Three-Stage Workflow Documentation
+The workflow is now prominently featured as a core concept:
+1. **Creating** - Proposal generation phase
+2. **Implementing** - Code development phase with explicit steps:
+   - Read proposal.md for understanding
+   - Read design.md for technical context
+   - Read tasks.md for checklist
+   - Implement tasks sequentially
+   - Mark complete immediately after each task
+3. **Archiving** - Post-deployment finalization phase
+
+This structure helps agents understand the lifecycle and their role at each stage. The implementation phase is particularly detailed to prevent common mistakes like skipping documentation or batching task completion.
+
+### CLI Documentation Updates
+- **Comprehensive command coverage** - All 9 primary commands documented
+- **`openspec list` prominence** - Essential for discovering changes and specs
+- **Interactive mode documentation** - How agents can use prompts effectively
+- **Complete flag documentation** - All options like --json, --type, --skip-specs
+- **Deprecation cleanup** - Remove noun-first patterns (openspec change show)
+
+### Agent-Specific Enhancements
+Based on industry best practices for coding agents (Claude Code, Cursor, etc.):
+
+**Implementation Workflow**
+- Explicit steps prevent skipping critical context
+- Reading proposal/design first ensures understanding before coding
+- Sequential task completion maintains focus
+- Immediate marking prevents losing track of progress
+- Addresses common failure mode: jumping straight to code
+
+**Spec Discovery Workflow**
+- Always check existing specs before creating new ones
+- Use `openspec list --specs` to discover current capabilities
+- Prefer modifying existing specs over creating duplicates
+- Prevents fragmentation and maintains coherent architecture
+
+**Decision Clarity**
+- Clear decision trees eliminating ambiguous conditions
+- Concrete examples for each decision branch
+- Simplified bug vs feature determination
+
+**Tool Usage Guidance**
+- Tool selection matrix (when to use Grep vs Glob vs Read)
+- Error recovery patterns for common failures
+- Verification workflows to confirm correctness
+
+**Context Management**
+- "Before Any Task" checklist for gathering context
+- What to read before starting any work
+- How to maintain state across interactions
+
+**Spec File Structure Documentation**
+- Complete examples with ADDED/MODIFIED/REMOVED sections
+- Critical scenario formatting (#### Scenario: headers)
+- Delta file location clarity (changes/{name}/specs/)
+- Addresses most common creation errors from retrospective
+
+**Troubleshooting and Debugging**
+- Common error messages with solutions
+- Delta detection debugging steps
+- Validation best practices
+- JSON output for inspection
+- Prevents hours of frustration from silent failures
+
+**Best Practices**
+- Be concise (one-line answers when appropriate)
+- Be specific (file.ts:42 line references)
+- Start simple (<100 lines, single-file defaults)
+- Justify complexity (require metrics/data)
+
+## Design Rationale
+
+### Why These Changes Matter
+
+**Cognitive Load Reduction**
+- Agents process instructions better with clear structure
+- Front-loading critical info reduces scanning time
+- Decision trees eliminate analysis paralysis
+
+**Industry Alignment**
+- Follows patterns proven effective in Claude Code, Cursor, GitHub Copilot
+- Addresses common failure modes (ambiguous decisions, missing context)
+- Optimizes for LLM strengths (pattern matching) vs weaknesses (calculations)
+
+**Addressing Critical Pain Points (from Retrospective)**
+- **Scenario formatting** - Biggest struggle, now explicitly documented with examples
+- **Complete spec structure** - Full examples prevent structural errors
+- **Delta detection issues** - Debugging commands help diagnose problems
+- **Silent parsing failures** - Troubleshooting section explains common issues
+
+**Practical Impact**
+- Faster agent comprehension of tasks
+- Fewer misinterpretations of requirements
+- More consistent implementation quality
+- Better error recovery when things go wrong
+- Prevents the most common errors identified in user experience
+
+## Trade-offs
+
+### What We're Removing
+- Lengthy explanations of concepts that can be inferred
+- Redundant examples that don't add clarity
+- Verbose edge case documentation (moved to reference section)
+- Deprecated command documentation
+
+### What We're Keeping
+- All critical workflow steps
+- Complete CLI command reference
+- Complexity management principles
+- Directory structure visualization
+- Quick reference summary
+
+## Implementation Notes
+
+The CLAUDE.md template is intentionally more concise than README.md since:
+- It appears in every project root
+- Agents can reference the full README.md for details
+- It needs to load quickly in AI context windows
+- Focus is on immediate actionable guidance

+# Update OpenSpec Agent Instructions
+
+## Why
+
+The current OpenSpec agent instructions need updates to follow best practices for AI assistant instructions (brevity, clarity, removing ambiguity), ensure CLI commands are current with the actual implementation, and properly document the three-stage workflow pattern that agents should follow.
+
+## What Changes
+
+### Core Structure Improvements
+- **Front-load the 3-stage workflow** as the primary mental model:
+  1. Creating a change proposal (proposal.md, spec deltas, design.md, tasks.md)
+  2. Implementing a change proposal:
+     - First read proposal.md to understand the change
+     - Read design.md if it exists for technical context
+     - Read tasks.md for the implementation checklist
+     - Complete tasks one by one
+     - Mark each task complete immediately after finishing
+  3. Archiving the change proposal (using archive command after deployment)
+- **Reduce instruction length by 50%** while maintaining all critical information
+- **Restructure with clear hierarchy**: Core Workflow → Quick Start → Commands → Details → Edge Cases
+
+### Decision Clarity Enhancements
+- **Add clear decision trees** for common scenarios (bug vs feature, proposal needed vs not)
+- **Remove ambiguous conditions** that confuse agent decision-making
+- **Add "Before Any Task" checklist** for context gathering
+- **Add "Before Creating Specs" rule** - Always check existing specs first to avoid duplicates
+
+### CLI Documentation Updates
+- **Complete command documentation** with all current functionality:
+  - `openspec init [path]` - Initialize OpenSpec in a project
+  - `openspec list` - List all active changes (default)
+  - `openspec list --specs` - List all specifications
+  - `openspec show [item]` - Display change or spec with auto-detection
+  - `openspec show` - Interactive mode for selection
+  - `openspec diff [change]` - Show spec differences for a change
+  - `openspec validate [item]` - Validate changes or specs
+  - `openspec archive [change]` - Archive completed change after deployment
+  - `openspec update [path]` - Update OpenSpec instruction files
+- **Document all flags and options**:
+  - `--json` output format for programmatic use
+  - `--type change|spec` for disambiguation
+  - `--skip-specs` for tooling-only archives
+  - `--strict` for strict validation mode
+  - `--no-interactive` to disable prompts
+- **Remove deprecated command references** (noun-first patterns like `openspec change show`)
+- **Add concrete examples** for each command variation
+- **Document debugging commands**:
+  - `openspec show [change] --json --deltas-only` for inspecting deltas
+  - `openspec validate [change] --strict` for comprehensive validation
+
+### Spec File Structure Documentation
+- **Complete spec file examples** showing proper structure:
+  ```markdown
+  ## ADDED Requirements
+  ### Requirement: Clear requirement statement
+  The system SHALL provide the functionality...
+  
+  #### Scenario: Descriptive scenario name
+  - **WHEN** condition occurs
+  - **THEN** expected outcome
+  - **AND** additional outcomes
+  ```
+- **Scenario formatting requirements** (critical - most common error):
+  - MUST use `#### Scenario:` headers (4 hashtags)
+  - NOT bullet lists or bold text
+  - Each requirement MUST have at least one scenario
+- **Delta file location** - Clear explanation:
+  - Spec files go in `changes/{name}/specs/` directory
+  - Deltas are automatically extracted from these files
+  - Use operation prefixes: ADDED, MODIFIED, REMOVED, RENAMED
+
+### Troubleshooting Section
+- **Common errors and solutions**:
+  - "Change must have at least one delta" → Check specs/ directory exists with .md files
+  - "Requirement must have at least one scenario" → Check scenario uses `#### Scenario:` format
+  - Silent scenario parsing failures → Verify exact header format
+- **Delta detection debugging**:
+  - Use `openspec show [change] --json --deltas-only` to inspect parsed deltas
+  - Check that spec files have operation prefixes (## ADDED Requirements)
+  - Verify specs/ subdirectory structure
+- **Validation best practices**:
+  - Always use `--strict` flag for comprehensive checks
+  - Use JSON output for debugging: `--json | jq '.deltas'`
+
+### Agent-Specific Improvements
+- **Implementation workflow** - Clear step-by-step process:
+  1. Read proposal.md to understand what's being built
+  2. Read design.md (if exists) for technical decisions
+  3. Read tasks.md for the implementation checklist
+  4. Implement tasks one by one in order
+  5. Mark each task complete immediately: `- [x] Task completed`
+  6. Never skip ahead or batch task completion
+- **Spec discovery workflow** - Always check existing specs before creating new ones:
+  - Use `openspec list --specs` to see all current specs
+  - Check if capability already exists before creating
+  - Prefer modifying existing specs over creating duplicates
+- **Tool selection matrix** - When to use Grep vs Glob vs Read
+- **Error recovery patterns** - How to handle common failures
+- **Context management guide** - What to read before starting tasks
+- **Verification workflows** - How to confirm changes are correct
+
+### Best Practices Section
+- **Be concise** - One-line answers when appropriate
+- **Be specific** - Use exact file paths and line numbers (file.ts:42)
+- **Start simple** - Default to <100 lines, single-file implementations
+- **Justify complexity** - Require data/metrics for any optimization
+
+## Impact
+
+- Affected specs: None (this is a tooling/documentation change)
+- Affected code: 
+  - `src/core/templates/claude-template.ts` - Update CLAUDE.md template
+- Affected documentation:
+  - `openspec/README.md` - Main OpenSpec instructions
+  - CLAUDE.md files generated by `openspec init` command
+
+Note: This is a tooling/infrastructure change that doesn't require spec updates. When archiving, use `openspec archive update-agent-instructions --skip-specs`.

+### Requirement: Skip Specs Option
+
+The archive command SHALL support a `--skip-specs` flag that skips all spec update operations and proceeds directly to archiving.
+
+#### Scenario: Skipping spec updates with flag
+
+- **WHEN** executing `openspec archive <change> --skip-specs`
+- **THEN** skip spec discovery and update confirmation
+- **AND** proceed directly to moving the change to archive

+# cli-change Specification
+
+## Purpose
+TBD - created by archiving change add-change-commands. Update Purpose after archive.
+## Requirements
+### Requirement: Change Command
+
+The system SHALL provide a `change` command with subcommands for displaying, listing, and validating change proposals.
+
+#### Scenario: Show change as JSON
+
+- **WHEN** executing `openspec change show update-error --json`
+- **THEN** parse the markdown change file
+- **AND** extract change structure and deltas
+- **AND** output valid JSON to stdout
+
+#### Scenario: List all changes
+
+- **WHEN** executing `openspec change list`
+- **THEN** scan the openspec/changes directory
+- **AND** return list of all pending changes
+- **AND** support JSON output with `--json` flag
+
+#### Scenario: Show only requirement changes
+
+- **WHEN** executing `openspec change show update-error --requirements-only`
+- **THEN** display only the requirement changes (ADDED/MODIFIED/REMOVED/RENAMED)
+- **AND** exclude why and what changes sections
+
+#### Scenario: Validate change structure
+
+- **WHEN** executing `openspec change validate update-error`
+- **THEN** parse the change file
+- **AND** validate against Zod schema
+- **AND** ensure deltas are well-formed
+
+### Requirement: Legacy Compatibility
+
+The system SHALL maintain backward compatibility with the existing `list` command while showing deprecation notices.
+
+#### Scenario: Legacy list command
+
+- **WHEN** executing `openspec list`
+- **THEN** display current list of changes (existing behavior)
+- **AND** show deprecation notice: "Note: 'openspec list' is deprecated. Use 'openspec change list' instead."
+
+#### Scenario: Legacy list with --all flag
+
+- **WHEN** executing `openspec list --all`
+- **THEN** display all changes (existing behavior)
+- **AND** show same deprecation notice
+
+### Requirement: Interactive show selection
+
+The change show command SHALL support interactive selection when no change name is provided.
+
+#### Scenario: Interactive change selection for show
+
+- **WHEN** executing `openspec change show` without arguments
+- **THEN** display an interactive list of available changes
+- **AND** allow the user to select a change to show
+- **AND** display the selected change content
+- **AND** maintain all existing show options (--json, --deltas-only)
+
+#### Scenario: Non-interactive fallback keeps current behavior
+
+- **GIVEN** stdin is not a TTY or `--no-interactive` is provided or environment variable `OPEN_SPEC_INTERACTIVE=0`
+- **WHEN** executing `openspec change show` without a change name
+- **THEN** do not prompt interactively
+- **AND** print the existing hint including available change IDs
+- **AND** set `process.exitCode = 1`
+
+### Requirement: Interactive validation selection
+
+The change validate command SHALL support interactive selection when no change name is provided.
+
+#### Scenario: Interactive change selection for validation
+
+- **WHEN** executing `openspec change validate` without arguments
+- **THEN** display an interactive list of available changes
+- **AND** allow the user to select a change to validate
+- **AND** validate the selected change
+
+#### Scenario: Non-interactive fallback keeps current behavior
