-# Repository Guidelines
+<!-- OPENSPEC:START -->
+# OpenSpec Instructions
 
-## Project Structure & Module Organization
-OpenSpec ships as a TypeScript-first CLI. Source code lives in `src`, with feature logic in `core`, interactive flows in `cli`, reusable helpers in `utils`, and command wiring in `commands`. After `pnpm run build`, deliverables land in `dist` and feed the published entry point `bin/openspec.js`. Specs and change proposals reside in `openspec/specs` and `openspec/changes`; update them whenever behavior shifts so automation stays aligned. Shared assets live in `assets`, and Vitest suites in `test` mirror the source layout for easy cross-reference.
+This project uses OpenSpec to manage AI assistant workflows.
 
-## Build, Test, and Development Commands
-Run `pnpm install` to sync dependencies. `pnpm run build` compiles TypeScript to `dist` and must stay green before release. Use `pnpm run dev` for a `tsc --watch` loop and `pnpm run dev:cli` to rebuild then execute the local CLI. `pnpm test` runs the Vitest suite once, `pnpm run test:watch` keeps it hot while iterating, and `pnpm run test:coverage` verifies instrumentation thresholds. Use `pnpm run changeset` when preparing a release entry.
-
-## Coding Style & Naming Conventions
-We follow idiomatic TypeScript with ES modules, 2-space indentation, and semicolons. Prefer named exports from index barrels and keep filenames kebab-cased (e.g., `list-command.ts`). Classes use `PascalCase`, functions and variables use `camelCase`, and constants representing flags may use `SCREAMING_SNAKE_CASE`. Keep modules small, colocate helpers under `src/utils`, and avoid new dependencies without spec-backed justification.
-
-## Testing Guidelines
-Every behavior change needs Vitest coverage under `test`, co-located by feature (e.g., `test/core/update.test.ts`). Name suites after the module under test and lean on `vitest.setup.ts` for shared configuration. Run `pnpm test` before pushing and add regression cases for each bug fix or spec requirement.
-
-## Commit & Pull Request Guidelines
-Commits follow Conventional Commits (`type(scope): subject`) and stay single-line. Reference the touched module in the scope when practical. Each PR should summarize the spec or issue it fulfills, list manual verification steps, and note updates to any `openspec/` assets. Include CLI output snippets or screenshots when the UX changes, and ensure CI and coverage checks pass before requesting review.
-
-## OpenSpec Workflow Tips
-Treat specs as the contract: update `openspec/project.md` or the relevant `openspec/specs/*.md` before coding, then run `pnpm run dev:cli` to validate the CLI against the revised artifacts. `openspec list --specs` confirms the catalog, and `openspec change` drafts proposals—commit these alongside code so reviewers can trace rationale to implementation.

+## Why
+Recent cross-shell regressions for `openspec` commands revealed that our existing unit/integration tests do not exercise the packaged CLI or shell-specific behavior. The prior attempt at Vitest spawn tests stalled because it coupled e2e coverage with `pnpm pack` installs, which fail in network-restricted environments. With those findings incorporated, we now need an approved plan to realign the work.
+
+## What Changes
+- Adopt a phased strategy that first stabilizes direct spawn testing of the built CLI (`node dist/cli/index.js`) using lightweight fixtures and a shared `runCLI` helper.
+- Expand coverage once the spawn harness is stable, keeping the initial matrix focused on bash jobs for Linux/macOS and `pwsh` on Windows while exercising both the direct `node dist/cli/index.js` invocation and the bin shim with non-TTY defaults and captured diagnostics.
+- Treat packaging/install validation as an optional CI safeguard: when a runner has registry access, run a simple pnpm-based pack→install→smoke-test flow; otherwise document it as out of scope while closing remaining hardening items.
+- Close out the remaining cross-shell hardening items: ensure `.gitattributes` covers packaged assets, enforce executable bits for CLI shims during CI, and finish the pending SIGINT handling improvements.
+
+## Impact
+- Tests: add `test/cli-e2e` spawn suite, create the shared `runCLI` helper, and adjust `vitest.setup.ts` as needed.
+- Tooling: update GitHub Actions workflows with the lightweight matrix above and (optionally) a packaging install check where network is available.
+- Docs: note phase progress and any limitations inline in this proposal (or the relevant spec) so future phases have clear context.
+
+### Phase 1 Status
+- Shared `test/helpers/run-cli.ts` guarantees the CLI bundle exists before spawning and enforces non-TTY defaults for every invocation.
+- New `test/cli-e2e/basic.test.ts` covers `--help`, `--version`, a successful `validate --all --json`, and an unknown-item error path against the `tmp-init` fixture copy.
+- Legacy top-level `validate` exec tests now rely on `runCLI`, avoiding manual `execSync` usage while keeping their fixture authoring intact.
+- CI matrix groundwork is in place (bash on Linux/macOS, pwsh on Windows) so the spawn suite runs the same way the helper does across supported shells.

+`openspec init` SHALL allow users to add configuration files for new AI coding assistants after the initial setup.
+
+#### Scenario: Configuring an extra tool after initial setup
+- **GIVEN** an `openspec/` directory already exists and at least one AI tool file is present

+- **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.
+
+#### Scenario: Preventing empty extend runs
+- **WHEN** OpenSpec is already initialized and the user selects no additional tools
+- **THEN** exit with code 1 after showing the existing-initialization guidance message
+
+### Requirement: Slash Command Configuration
+The init command SHALL generate slash command files for supported editors using shared templates.
+
+#### Scenario: Generating slash commands for Claude Code
+- **WHEN** the user selects Claude Code during initialization
+- **THEN** create `.claude/commands/openspec/proposal.md`, `.claude/commands/openspec/apply.md`, and `.claude/commands/openspec/archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
+
+#### Scenario: Generating slash commands for Cursor
+- **WHEN** the user selects Cursor during initialization
+- **THEN** create `.cursor/commands/openspec-proposal.md`, `.cursor/commands/openspec-apply.md`, and `.cursor/commands/openspec-archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage

 Manual creation of OpenSpec structure is error-prone and creates adoption friction. A standardized init command ensures:
 - Consistent structure across all projects
 - Proper AI instruction files are always included
 - Quick onboarding for new projects
