+description: Ensure manual testing of key functionality before committing changes
+globs: **/*.{ts,js,go,svelte}
+---
+<rule>
+When making changes that affect functionality:
+
+1. Build and Run Requirements:
+   - Run `./build.sh` to ensure everything builds
+   - Start the application with `./notes-app`
+   - Wait for server to be ready at http://localhost:3000
+
+2. Core Functionality Testing:
+   - Test all features directly affected by changes
+   - For note-related changes:
+     - Create a new note
+     - Edit an existing note
+     - Check note links work (if link-related changes)
+     - Verify note deletion
+   - For UI changes:
+     - Check responsive behavior
+     - Verify all interactive elements work
+     - Test navigation flows
+
+3. Cross-Feature Testing:
+   - Test features that interact with changed components
+   - Verify no regressions in related functionality
+   - Check both success and error paths
+
+4. Browser Testing:
+   - Test in primary development browser
+   - Verify critical paths in secondary browser
+   - Check console for errors
+
+5. Error Cases:
+   - Test invalid inputs
+   - Verify error messages are clear
+   - Check error handling behavior
+
+6. Cleanup:
+   - Stop running services
+   - Clean up test data if necessary
+   - Reset to known good state
+
+7. Documentation:
+   - Add testing steps to commit message body
+   - Note any special test cases or considerations
+   - Document any known limitations

+examples:
+  - input: |
+      # Bad: Direct commit after code changes
+      git add . && git commit -m "feat: add note linking"
+    output: |
+      # Good: Manual testing before commit
+      ./build.sh
+      ./notes-app
+      # Manual testing steps...
+      # 1. Create note "Test Note"
+      # 2. Create note "Linked Note"
+      # 3. Add link [[Linked Note]] to "Test Note"
+      # 4. Verify link works
+      git add . && git commit -m "feat: add note linking
+
+      Testing completed:
+      - Created and linked notes successfully
+      - Verified bidirectional navigation
+      - Tested invalid link handling"
+
+  - input: |
+      # Bad: Commit UI changes without testing
+      git commit -m "fix: update note editor styling"
+    output: |
+      # Good: Test UI changes across scenarios
+      ./build.sh
+      ./notes-app
+      # 1. Test editor with short/long content
+      # 2. Verify mobile responsiveness
+      # 3. Check different browsers
+      git commit -m "fix: update note editor styling
+
+      Tested:
+      - Responsive behavior on desktop/mobile
+      - Long content handling
+      - Chrome and Firefox compatibility"
