 <rule>
   When using Bun:
-  1. Always use the local installation at ~/.bun/bin/bun
-  2. Use Bun instead of Node/npm for all package management and running scripts
-  3. For running commands, use the full path: ~/.bun/bin/bun
-  4. Replace npm scripts with Bun equivalents in package.json
-  5. Use Bun for installing, running, and testing packages
-  6. Ensure Bun is used for all CI/CD pipelines and automation scripts
-  7. Document any exceptions where Node/npm must be used
-
-Command mappings:
+  1. Installation and Path:
+     - Primary: Use Bun from PATH if available
+     - Fallback: $HOME/.bun/bin/bun
+     - Always use command path resolution pattern from command-paths.mdc
+  2. Package Management:
+     - Use Bun instead of Node/npm for all package management
+     - Replace npm scripts with Bun equivalents in package.json
+     - Use Bun for installing, running, and testing packages
+  3. Command Mappings:
      - npm install -> bun install
      - npm run -> bun run
      - node -> bun
+  4. CI/CD and Automation:
+     - Ensure Bun is used for all CI/CD pipelines
+     - Document any exceptions where Node/npm must be used
+     - Use build.sh for consistent builds across environments
 
 Never use npm or node commands directly.

+When working with Go:
+
+1. Installation and Path:
+   - Primary: Use Go from PATH if available
+   - Fallback: /usr/local/go/bin/go
+   - Always use command path resolution pattern from command-paths.mdc
+
+2. Dependencies:
+   - Prefer pure Go implementations over CGO when available
+   - Examples:
+     - Use github.com/glebarez/sqlite over gorm.io/driver/sqlite
+     - Document any CGO dependencies in go.mod comments
+
+3. Build Process:
+   - Always run `go mod tidy` after dependency changes
+   - Verify builds work without CGO: `CGO_ENABLED=0 go build`
+   - Use build.sh for full application builds
+
+4. Module Management:
+   - Keep go.mod and go.sum in sync
+   - Document version constraints
+   - Run `go mod verify` before commits
