+            IMPORTANT: You must NEVER push directly to the main branch. Always:
+            1. Create a new feature branch (claude/feature-name)
+            2. Make your changes on the feature branch
+            3. Open a pull request to main
+            4. Wait for review and approval before merging
+
+            COMMIT MESSAGE FORMAT: Always use conventional commits with capital letters. 
+            Follow the format: "type(scope): Description" where the description starts with a capital letter.
+            Examples: "feat(a2a): Add retry mechanism for agent connections", "fix(auth): Resolve token validation issue"
+
+            Follow the development workflow specified in the coding instructions.
