+# Dev Container Setup
+
+This directory contains the VS Code dev container configuration for OpenSpec development.
+
+## What's Included
+
+- **Node.js 20 LTS** (>=20.19.0) - TypeScript/JavaScript runtime
+- **pnpm** - Fast, disk space efficient package manager
+- **Git + GitHub CLI** - Version control tools
+- **VS Code Extensions**:
+  - ESLint & Prettier for code quality
+  - Vitest Explorer for running tests
+  - GitLens for enhanced git integration
+  - Error Lens for inline error highlighting
+  - Code Spell Checker
+  - Path IntelliSense
+
+## How to Use
+
+### First Time Setup
+
+1. **Install Prerequisites** (on your local machine):
+   - [VS Code](https://code.visualstudio.com/)
+   - [Docker Desktop](https://www.docker.com/products/docker-desktop)
+   - [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+
+2. **Open in Container**:
+   - Open this project in VS Code
+   - You'll see a notification: "Folder contains a Dev Container configuration file"
+   - Click "Reopen in Container"
+
+   OR
+
+   - Open Command Palette (`Cmd/Ctrl+Shift+P`)
+   - Type "Dev Containers: Reopen in Container"
+   - Press Enter
+
+3. **Wait for Setup**:
+   - The container will build (first time takes a few minutes)
+   - `pnpm install` runs automatically via `postCreateCommand`
+   - All extensions install automatically
+
+### Daily Development
+
+Once set up, the container preserves your development environment:
+
+```bash
+# Run development build
+pnpm run dev
+
+# Run CLI in development
+pnpm run dev:cli
+
+# Run tests
+pnpm test
+
+# Run tests in watch mode
+pnpm test:watch
+
+# Build the project
+pnpm run build
+```
+
+### SSH Keys
+
+Your SSH keys are mounted read-only from `~/.ssh`, so git operations work seamlessly with GitHub/GitLab.
+
+### Rebuilding the Container
+
+If you modify `.devcontainer/devcontainer.json`:
+- Command Palette → "Dev Containers: Rebuild Container"
+
+## Benefits
+
+- No need to install Node.js or pnpm on your local machine
+- Consistent development environment across team members
+- Isolated from other Node.js projects on your machine
+- All dependencies and tools containerized
+- Easy onboarding for new developers
+
+## Troubleshooting
+
+**Container won't build:**
+- Ensure Docker Desktop is running
+- Check Docker has enough memory allocated (recommend 4GB+)
+
+**Extensions not appearing:**
+- Rebuild the container: "Dev Containers: Rebuild Container"
+
+**Permission issues:**
+- The container runs as the `node` user (non-root)
+- Files created in the container are owned by this user

+# Add Archive Command Arguments
+
+## Why
+The `/openspec:archive` slash command currently lacks argument support, forcing the AI to infer which change to archive from conversation context or by listing all changes. This creates a safety risk where the wrong proposal could be archived if the context is ambiguous or multiple changes exist. Users expect to specify the change ID explicitly, matching the behavior of the CLI command `openspec archive <id>`.
+
+## What Changes
+- Add `$ARGUMENTS` placeholder to the OpenCode archive slash command frontmatter (matching existing pattern for proposal command)
+- Update archive command template steps to validate the specific change ID argument when provided
+- Note: Codex, GitHub Copilot, and Amazon Q already have `$ARGUMENTS` for archive; Claude/Cursor/Windsurf/Kilocode don't support arguments
+
+## Impact
+- Affected specs: `cli-update` (slash command generation logic)
+- Affected code:
+  - `src/core/configurators/slash/opencode.ts` (add `$ARGUMENTS` to archive frontmatter)
+  - `src/core/templates/slash-command-templates.ts` (archive template steps for argument validation)
+- Breaking: No - this is additive functionality that makes the command safer
+- User-facing: Yes - OpenCode users will be able to pass the change ID as an argument: `/openspec:archive <change-id>`

+# CLI Update Specification Delta
+
+## MODIFIED Requirements
+
+### Requirement: Slash Command Updates
+The update command SHALL refresh existing slash command files for configured tools without creating new ones, and ensure the OpenCode archive command accepts change ID arguments.
+
+#### Scenario: Updating slash commands for OpenCode
+- **WHEN** `.opencode/command/` contains `openspec-proposal.md`, `openspec-apply.md`, and `openspec-archive.md`
+- **THEN** refresh each file using shared templates
+- **AND** ensure templates include instructions for the relevant workflow stage
+- **AND** ensure the archive command includes `$ARGUMENTS` placeholder in frontmatter for accepting change ID arguments
+
+## ADDED Requirements
+
+### Requirement: Archive Command Argument Support
+The archive slash command template SHALL support optional change ID arguments for tools that support `$ARGUMENTS` placeholder.
+
+#### Scenario: Archive command with change ID argument
+- **WHEN** a user invokes `/openspec:archive <change-id>` with a change ID
+- **THEN** the template SHALL instruct the AI to validate the provided change ID against `openspec list`
+- **AND** use the provided change ID for archiving if valid
+- **AND** fail fast if the provided change ID doesn't match an archivable change
+
+#### Scenario: Archive command without argument (backward compatibility)
+- **WHEN** a user invokes `/openspec:archive` without providing a change ID
+- **THEN** the template SHALL instruct the AI to identify the change ID from context or by running `openspec list`
+- **AND** proceed with the existing behavior (maintaining backward compatibility)
+
+#### Scenario: OpenCode archive template generation
+- **WHEN** generating the OpenCode archive slash command file
+- **THEN** include the `$ARGUMENTS` placeholder in the frontmatter
+- **AND** wrap it in a clear structure like `<ChangeId>\n  $ARGUMENTS\n</ChangeId>` to indicate the expected argument
+- **AND** include validation steps in the template body to check if the change ID is valid

+# Implementation Tasks
+

+- [x] 1.2 Format it as `<ChangeId>\n  $ARGUMENTS\n</ChangeId>` or similar structure for clarity

+- [x] 2.2 Keep backward compatibility - allow inferring from context if no argument provided

+
+## 3. Update Documentation
+- [x] 3.1 Update AGENTS.md archive examples to show argument usage
+- [x] 3.2 Document that OpenCode now supports `/openspec:archive <change-id>`
+
