+# VS Code Extension CI/CD Setup
+
+This document explains the CI/CD setup for the Task Master VS Code extension using automated changesets.
+
+## 🔄 Workflows Overview
+
+### 1. Extension CI (`extension-ci.yml`)
+
+#### Triggers
+
+- Push to `main` or `next` branches (only when extension files change)
+- Pull requests to `main` or `next` (only when extension files change)
+
+#### What it does
+
+- ✅ Lints and type-checks the extension code
+- 🔨 Builds the extension (`npm run build`)
+- 📦 Creates a clean package (`npm run package`)
+- 🧪 Runs tests with VS Code test framework
+- 📋 Creates a test VSIX package to verify packaging works
+- 💾 Uploads build artifacts for inspection
+
+### 2. Version & Publish (`version.yml`)
+
+**Triggers:**
+- Push to `main` branch
+
+**What it does:**
+- 🔍 Detects changeset files for pending releases
+- 📝 Creates "Version Packages" PR with updated versions and CHANGELOG
+- 🤖 When Version PR is merged, automatically:
+  - 🔨 Builds and packages the extension
+  - 🏷️ Creates git tags with changeset automation
+  - 📤 Publishes to VS Code Marketplace
+  - 🌍 Publishes to Open VSX Registry
+  - 📊 Updates package versions and CHANGELOG
+
+## 🚀 Changeset Workflow
+
+### Creating Changes
+When making changes to the extension:
+
+1. **Make your code changes**
+2. **Create a changeset**:
+   ```bash
+   # From project root
+   npx changeset add
+   ```
+3. **Select the extension package**: Choose `taskr-kanban` when prompted
+4. **Select version bump type**:
+   - `patch`: Bug fixes, minor updates
+   - `minor`: New features, backwards compatible
+   - `major`: Breaking changes
+5. **Write a summary**: Describe what changed for users
+6. **Commit changeset file** along with your code changes
+7. **Push to feature branch** and create PR
+
+### Automated Publishing Process
+1. **PR with changeset** gets merged to `main`
+2. **Version workflow** detects changesets and creates "Version Packages" PR
+3. **Review and merge** the Version PR
+4. **Automated publishing** happens immediately:
+   - Extension is built using 3-file packaging system
+   - VSIX package is created and tested
+   - Published to VS Code Marketplace (if `VSCE_PAT` is set)
+   - Published to Open VSX Registry (if `OVSX_PAT` is set)
+   - Git tags are created: `taskr-kanban@1.0.1`
+   - CHANGELOG is updated automatically
+
+## 🔑 Required Secrets
+
+To use the automated publishing, you need to set up these GitHub repository secrets:
+
+### `VSCE_PAT` (VS Code Marketplace Personal Access Token)
+1. Go to [Azure DevOps](https://dev.azure.com/)
+2. Sign in with your Microsoft account
+3. Create a Personal Access Token:
+   - **Name**: VS Code Extension Publishing
+   - **Organization**: All accessible organizations
+   - **Expiration**: Custom (recommend 1 year)
+   - **Scopes**: Custom defined → **Marketplace** → **Manage**
+4. Copy the token and add it to GitHub Secrets as `VSCE_PAT`
+
+### `OVSX_PAT` (Open VSX Registry Personal Access Token)
+1. Go to [Open VSX Registry](https://open-vsx.org/)
+2. Sign in with your GitHub account
+3. Go to your [User Settings](https://open-vsx.org/user-settings/tokens)
+4. Create a new Access Token:
+   - **Description**: VS Code Extension Publishing
+   - **Scopes**: Leave default (full access)
+5. Copy the token and add it to GitHub Secrets as `OVSX_PAT`
+
+### `GITHUB_TOKEN` (automatically provided)
+This is automatically available in GitHub Actions - no setup required.
+
+## 📋 Version Management
+
+### Changeset-Based Versioning
+Versions are automatically managed by changesets:
+
+- **No manual version updates needed** - changesets handle this automatically
+- **Semantic versioning** is enforced based on changeset types
+- **Changelog generation** happens automatically
+- **Git tagging** is handled by the automation
+
+### Critical Fields Sync
+The automation ensures these fields stay in sync between `package.json` and `package.publish.json`:
+
+```json
+{
+  "version": "1.0.2",                    // ✅ AUTO-SYNCED
+  "publisher": "Hamster",        // ⚠️ MUST MATCH MANUALLY
+  "displayName": "taskr: Task Master Kanban", // ⚠️ MUST MATCH MANUALLY
+  "description": "...",                  // ⚠️ MUST MATCH MANUALLY
+  "engines": { "vscode": "^1.93.0" },   // ⚠️ MUST MATCH MANUALLY
+  "categories": [...],                   // ⚠️ MUST MATCH MANUALLY
+  "contributes": { ... }                 // ⚠️ MUST MATCH MANUALLY
+}
+```
+
+**Note**: Only `version` is automatically synced. Other fields must be manually kept in sync.
+
+## 🔍 Monitoring Builds
+
+### CI Status
+
+- **Green ✅**: Extension builds and tests successfully
+- **Red ❌**: Build/test failures - check logs for details
+- **Yellow 🟡**: Partial success - some jobs may have warnings
+
+### Version PR Status
+
+- **Version PR Created**: Changesets detected, review and merge to publish
+- **No Version PR**: No changesets found, no releases pending
+- **Version PR Merged**: Automated publishing triggered
+
+### Release Status
+
+- **Published 🎉**: Extension live on VS Code Marketplace and Open VSX
+- **Skipped ℹ️**: No changesets found, no release needed
+- **Failed ❌**: Check logs - often missing secrets or build issues
+
+### Artifacts
+
+Workflows upload artifacts that you can download:
+
+- **CI**: Test results, built files, and VSIX package
+- **Version**: Final VSIX package and published extension
+
+## 🛠️ Troubleshooting
+
+### Common Issues
+
+#### No Version PR Created
+
+- **Check**: Changeset files exist in `.changeset/` directory
+- **Check**: Changeset refers to `taskr-kanban` package name
+- **Check**: Changes were pushed to `main` branch
+- **Solution**: Create changeset with `npx changeset add`
+
+#### Version PR Not Publishing
+
+- **Check**: Version PR was actually merged (not just closed)
+- **Check**: Required secrets (`VSCE_PAT`, `OVSX_PAT`) are set
+- **Check**: No build failures in workflow logs
+- **Solution**: Re-run workflow or check secret configuration
+
+#### `VSCE_PAT` is not set Error
+
+- Ensure `VSCE_PAT` secret is added to repository
+- Check token hasn't expired
+- Verify token has Marketplace → Manage permissions
+
+#### `OVSX_PAT` is not set Error
+
+- Ensure `OVSX_PAT` secret is added to repository
+- Check token hasn't expired
+- Verify you're signed in to Open VSX Registry with GitHub
+
+#### Build Failures
+
+- Check extension code compiles locally: `cd apps/extension && npm run build`
+- Verify tests pass locally: `npm run test`
+- Check for TypeScript errors: `npm run check-types`
+
+#### Packaging Failures
+
+- Ensure clean package builds: `npm run package`
+- Check vsix-build structure is correct
+- Verify `package.publish.json` has correct `repository` field
+
+#### Changeset Issues
+
+- **Wrong package name**: Ensure changeset refers to `taskr-kanban`
+- **Invalid format**: Check changeset markdown format is correct
+- **Merge conflicts**: Resolve any conflicts in changeset files
+
+## 📁 File Structure Impact
+
+The CI workflows respect the 3-file packaging system:
+- **Development**: Uses `package.json` for dependencies and scripts
+- **Release**: Uses `package.publish.json` for clean marketplace package
+- **Build**: Uses `package.mjs` to create `vsix-build/` for final packaging
+- **Changesets**: Automatically manage versions across the system
+
+## 🌍 Dual Registry Publishing
+
+Your extension will be automatically published to both:
+- **VS Code Marketplace** - For official VS Code users
+- **Open VSX Registry** - For Cursor, Windsurf, VSCodium, Gitpod, Eclipse Theia, and other compatible editors
+
+## 🎯 Benefits of Changeset Automation
+
+- ✅ **Automated versioning**: No manual version bumps needed
+- ✅ **Generated changelogs**: Automatic, accurate release notes
+- ✅ **Semantic versioning**: Enforced through changeset types
+- ✅ **Git tagging**: Proper tags for extension releases
+- ✅ **Conflict prevention**: Clear separation of extension vs. main package versions
+- ✅ **Review process**: Version changes are reviewable via PR
+- ✅ **Rollback capability**: Easy to revert if issues arise
+
+This ensures clean, predictable, and fully automated publishing to both registries! 🚀

+# VS Code Extension Development Guide
+
+## 📁 File Structure Overview
+
+This VS Code extension uses a **3-file packaging system** to avoid dependency conflicts during publishing:
+
+```
+apps/extension/
+├── package.json           # Development configuration
+├── package.publish.json   # Clean publishing configuration  
+├── package.mjs           # Build script for packaging
+├── .vscodeignore         # Files to exclude from extension package
+└── vsix-build/           # Generated clean package directory
+```
+
+## 📋 File Purposes
+
+### `package.json` (Development)
+- **Purpose**: Development environment with all build tools
+- **Contains**: 
+  - All `devDependencies` needed for building
+  - Development scripts (`build`, `watch`, `lint`, etc.)
+  - Development package name: `"taskr"`
+- **Used for**: Local development, building, testing
+
+### `package.publish.json` (Publishing)
+- **Purpose**: Clean distribution version for VS Code Marketplace
+- **Contains**:
+  - **No devDependencies** (avoids dependency conflicts)
+  - Publishing metadata (`keywords`, `repository`, `categories`)
+  - Marketplace package name: `"taskr-kanban"`
+  - VS Code extension configuration
+- **Used for**: Final extension packaging
+
+### `package.mjs` (Build Script)
+- **Purpose**: Creates clean package for distribution
+- **Process**:
+  1. Builds the extension (`build:js` + `build:css`)
+  2. Creates clean `vsix-build/` directory
+  3. Copies only essential files (no source code)
+  4. Renames `package.publish.json` → `package.json`
+  5. Ready for `vsce package`
+
+## 🚀 Development Workflow
+
+### Local Development
+```bash
+# Install dependencies
+npm install
+
+# Start development with hot reload
+npm run watch
+
+# Run just JavaScript build
+npm run build:js
+
+# Run just CSS build  
+npm run build:css
+
+# Full production build
+npm run build
+
+# Type checking
+npm run check-types
+
+# Linting
+npm run lint
+```
+
+### Testing in VS Code
+1. Press `F5` in VS Code to launch Extension Development Host
+2. Test your extension functionality in the new window
+3. Use `Developer: Reload Window` to reload after changes
+
+## 📦 Production Packaging
+
+### Step 1: Build Clean Package
+```bash
+npm run package
+```
+This creates `vsix-build/` with clean distribution files.
+
+### Step 2: Create VSIX
+```bash
+cd vsix-build
+npx vsce package --no-dependencies
+```
+Creates: `taskr-kanban-1.0.1.vsix`
+
+### Alternative: One Command
+```bash
+npm run package && cd vsix-build && npx vsce package --no-dependencies
+```
+
+## 🔄 Keeping Files in Sync
+
+### Critical Fields to Sync Between Files
+
+When updating extension metadata, ensure these fields match between `package.json` and `package.publish.json`:
+
+#### Version & Identity
+```json
+{
+  "version": "1.0.1",                    // ⚠️ MUST MATCH
+  "publisher": "Hamster",        // ⚠️ MUST MATCH  
+  "displayName": "taskr: Task Master Kanban", // ⚠️ MUST MATCH
+  "description": "A visual Kanban board...",  // ⚠️ MUST MATCH
+}
+```
+
+#### VS Code Configuration
+```json
+{
+  "engines": { "vscode": "^1.101.0" },   // ⚠️ MUST MATCH
+  "categories": [...],                    // ⚠️ MUST MATCH
+  "activationEvents": [...],              // ⚠️ MUST MATCH
+  "main": "./dist/extension.js",          // ⚠️ MUST MATCH
+  "contributes": { ... }                  // ⚠️ MUST MATCH EXACTLY
+}
+```
+
+### Key Differences (Should NOT Match)
+```json
+// package.json (dev)
+{
+  "name": "taskr",                       // ✅ Short dev name
+  "devDependencies": { ... },            // ✅ Only in dev file
+  "scripts": { ... }                     // ✅ Build scripts
+}
+
+// package.publish.json (publishing)
+{
+  "name": "taskr-kanban",               // ✅ Marketplace name
+  "keywords": [...],                     // ✅ Only in publish file
+  "repository": "https://github.com/...", // ✅ Only in publish file
+  // NO devDependencies                  // ✅ Clean for publishing
+  // NO build scripts                    // ✅ Not needed in package
+}
+```
+
+## 🤖 Automated Release Process
+
+### Changesets Workflow
+This extension uses [Changesets](https://github.com/changesets/changesets) for automated version management and publishing.
+
+#### Adding Changes
+When making changes to the extension:
+
+1. **Make your code changes**
+2. **Create a changeset**:
+   ```bash
+   # From project root
+   npx changeset add
+   ```
+3. **Select the extension package**: Choose `taskr-kanban` when prompted
+4. **Select version bump type**:
+   - `patch`: Bug fixes, minor updates
+   - `minor`: New features, backwards compatible
+   - `major`: Breaking changes
+5. **Write a summary**: Describe what changed for users
+
+#### Automated Publishing
+The automation workflow runs on pushes to `main`:
+
+1. **Version Workflow** (`.github/workflows/version.yml`):
+   - Detects when changesets exist
+   - Creates a "Version Packages" PR with updated versions and CHANGELOG
+   - When the PR is merged, automatically publishes the extension
+
+2. **Release Process** (`scripts/release.sh`):
+   - Builds the extension using the 3-file packaging system
+   - Creates VSIX package
+   - Publishes to VS Code Marketplace (if `VSCE_PAT` is set)
+   - Publishes to Open VSX Registry (if `OVSX_PAT` is set)
+   - Creates git tags for the extension version
+
+#### Required Secrets
+For automated publishing, these secrets must be set in the repository:
+
+- `VSCE_PAT`: Personal Access Token for VS Code Marketplace
+- `OVSX_PAT`: Personal Access Token for Open VSX Registry
+- `GITHUB_TOKEN`: Automatically provided by GitHub Actions
+
+#### Manual Release
+If needed, you can manually trigger a release:
+
+```bash
+# From project root
+./scripts/release.sh
+```
+
+### Extension Tagging
+The extension uses a separate tagging strategy from the main package:
+
+- **Extension tags**: `taskr-kanban@1.0.1`
+- **Main package tags**: `task-master-ai@2.1.0`
+
+This allows independent versioning and prevents conflicts in the monorepo.
+
+## 🔍 Troubleshooting
+
+### Dependency Conflicts
+**Problem**: `vsce package` fails with missing dependencies
+**Solution**: Use the 3-file system - never run `vsce package` from root
+
+### Build Failures
+**Problem**: Extension not working after build
+**Check**:
+1. All files copied to `vsix-build/dist/`
+2. `package.publish.json` has correct `main` field
+3. VS Code engine version compatibility
+
+### Sync Issues
+**Problem**: Extension works locally but fails when packaged
+**Check**: Ensure critical fields are synced between package files
+
+### Changeset Issues
+**Problem**: Version workflow not triggering
+**Check**: 
+1. Changeset files exist in `.changeset/`
+2. Package name in changeset matches `package.publish.json`
+3. Changes are pushed to `main` branch
+
+**Problem**: Publishing fails
+**Check**:
+1. Required secrets are set in repository settings
+2. `package.publish.json` has correct repository URL
+3. Build process completes successfully
+
+## 📝 Version Release Checklist
+
+### Manual Releases
+1. **Create changeset**: `npx changeset add`
+2. **Update critical fields** in both `package.json` and `package.publish.json`
+3. **Test locally** with `F5` in VS Code
+4. **Commit and push** to trigger automated workflow
+
+### Automated Releases (Recommended)
+1. **Create changeset**: `npx changeset add`
+2. **Push to feature branch** and create PR
+3. **Merge PR** - this triggers version PR creation
+4. **Review and merge version PR** - this triggers automated publishing
+
+## 🎯 Why This System?
+
+- **Avoids dependency conflicts**: VS Code doesn't see dev dependencies
+- **Clean distribution**: Only essential files in final package
+- **Faster packaging**: No dependency resolution during `vsce package`
+- **Maintainable**: Clear separation of dev vs. production configs
+- **Reliable**: Consistent, conflict-free packaging process
+- **Automated**: Changesets handle versioning and publishing automatically
+- **Traceable**: Clear changelog and git tags for every release
+
+---
+
+**Remember**: Always use `npx changeset add` for changes, then push to trigger automated releases! 🚀
