Every merge leaves the repo in a better state than before.** # Project Context **vscode-python-environments** — A VS Code extension providing a unified Python environment experience. Manages environment discovery, creation, selection, terminal activation, and package management across multiple Python managers. **Stack:** TypeScript, Node.js, VS Code Extension API, Webpack, Mocha/Sinon, PET (Rust locator) **Key Architecture:** - `src/managers/` — Environment manager implementations (venv, conda, poetry, pipenv, pyenv, pixi, uv) - `src/features/` — Core features (terminal, settings, views, execution) - `src/common/` — Shared utilities and APIs - `analysis/` — Python scripts for codebase health snapshots --- # Available Skills Load these skills on-demand for detailed knowledge: | Skill | When to Use | | -------------------------- | ------------------------------------------------- | | `generate-snapshot` | Generate codebase health snapshot for planning | | `run-pre-commit-checks` | Run mandatory checks before committing | | `cross-platform-paths` | Reviewing/writing path-related code | | `settings-precedence` | Reviewing/writing settings code | | `python-manager-discovery` | Working on specific manager (poetry, conda, etc.) | --- # Automated Hooks These hooks run automatically (configured in `.github/hooks/`): | Hook | What it Does | | ---------------- | ---------------------------------------------------------------- | | **SessionStart** | Injects git context, open issues, available skills | | **PostToolUse** | Runs ESLint on edited TypeScript files | | **Stop** | Blocks if uncommitted TS changes exist without pre-commit checks | --- # Workflow Overview ``` Planning → Development → Review → Merge ``` --- # Planning Phase ## When asked "What should we work on next?" 1. **Gather context:** - Check open GitHub issues (`github/list_issues`, `github/search_issues`) - Generate snapshot: Use `generate-snapshot` skill for details - Check open PRs for related work 2. **Analyze and prioritize:** - Cross-reference issues against snapshot `priority_hotspots` and `debt_indicators` - Consider cross-platform impact (Windows, macOS, Linux) - Use snapshot data to identify refactoring opportunities 3. **Present a curated priority list:** - 3–5 actionable items ranked by impact - For each: brief description, affected components, complexity - Recommend the top pick with reasoning 4. **User picks** → proceed to Development Phase --- # Development Phase ## 1. Create an Issue Every piece of work starts with a GitHub issue — no exceptions. - Search for duplicates first (`github/search_issues`) - Create issue with clear title, description, and labels ## 2. Create a Feature Branch ```powershell git checkout main; git pull git checkout -b feature/issue-N # or bug/issue-N, chore/issue-N ``` ## 3. Implement Changes Follow guidelines from `.github/instructions/generic.instructions.md`: - **Paths:** Use `cross-platform-paths` skill for patterns - **Settings:** Use `settings-precedence` skill for patterns - **Managers:** Use `python-manager-discovery` skill for manager-specific knowledge - **Localization:** `l10n.t()` for user-facing messages - **Logging:** `traceLog`/`traceVerbose`, never `console.log` ### High-Risk Areas These areas require extra scrutiny: | Area | Common Issues | | ------------------------------------------- | ------------------------------------- | | `src/managers/common/nativePythonFinder.ts` | Type guards, cache, resource leaks | | `src/features/terminal/` | Timing, shell detection, reveal logic | | `src/managers/poetry/` | {cache-dir} placeholder, env vars | | `src/managers/pyenv/` | Windows path calculation | | `src/features/settings/` | Precedence, inspect() vs get() | ## 4. Self-Review (MANDATORY) **Before every commit, invoke the Reviewer agent as a sub-agent.** Run **Reviewer** agent (`.github/agents/reviewer.agent.md`) with: 1. Get changed files: `git diff --name-only` 2. Read and review each file 3. Report: Critical / Important / Suggestions / Questions **Loop until Reviewer returns clean or only minor suggestions.** ## 5. Pre-Commit Checks (REQUIRED) Use `run-pre-commit-checks` skill for details. Quick reference: ```powershell npm run lint # ESLint npm run compile-tests # TypeScript npm run unittest # Mocha ``` **Note:** The `PostToolUse` hook automatically runs ESLint on edited files. ## 6. Commit Format: `[type]: brief description (Fixes #N)` Types: `feat`, `fix`, `chore`, `docs`, `refactor`, `test` ## 7. Push & Create PR ```powershell git push -u origin feature/issue-N ``` Create PR via `github/create_pull_request`: - **Title:** Same as commit message - **Body:** 1-2 sentence summary + bullet list (5-10 items) + `Fixes #N` --- # Review & Iterate Phase **DO NOT yield to the user until review is complete or 8 minutes have elapsed.** ## 1. Request Copilot Review After creating PR: `github/request_copilot_review` ## 2. Wait for Review - Wait ~2 minutes initially, then poll every 30 seconds - Maximum wait: 8 minutes total - Use: `github/pull_request_read (method: get_review_comments)` ## 3. Handle Review Comments 1. Read and understand each comment 2. Make fixes for actionable comments 3. **Re-run Reviewer agent on fixes** (mandatory) 4. **Run pre-commit checks** 5. Resolve addressed threads: ```powershell # Get thread IDs gh api graphql -f query='{ repository(owner: "microsoft", name: "vscode-python-environments") { pullRequest(number: N) { reviewThreads(first: 50) { nodes { id isResolved } } } } }' # Resolve each thread gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "THREAD_ID"}) { thread { isResolved } } }' ``` 6. Commit: `fix: address review feedback (PR #N)` 7. Push and re-request Copilot review 8. Repeat from step 2 ## 4. Review Complete Review complete when: - No actionable comments, OR - PR is Approved, OR - 8 min polling with no unresolved threads **DO NOT suggest merging** until one condition is met. --- # Merge & Cleanup 1. **Merge:** `github/merge_pull_request` 2. **Delete branch:** ```powershell git checkout main; git pull git branch -d feature/issue-N ``` 3. **CI triggers** on push to main --- # Principles 1. **Issue-first:** No code without an issue 2. **Review-always:** Reviewer agent before every commit 3. **Small PRs:** One issue, one branch, one PR 4. **Cross-platform:** Consider Windows, macOS, Linux 5. **Settings precedence:** workspace folder → workspace → user 6. **User decides:** Present options, let user choose 7. **Ship clean:** Every merge improves the repo --- # Quick Reference Commands | Task | Command | | ----------------- | ------------------------------------------------------ | | Unit tests | `npm run unittest` | | Lint | `npm run lint` | | Type check | `npm run compile-tests` | | Build extension | `npm run compile` | | Smoke tests | `npm run compile && npm run smoke-test` | | Generate snapshot | `cd analysis && python snapshot.py -o ./snapshot.json` | | Package VSIX | `npm run vsce-package` |
