+# Claude Assistant Guidelines
+
+This document contains guidelines for Claude when working on this project.
+
+## Git Workflow
+
+### Commits and Pushes
+
+**IMPORTANT: Never commit or push without explicit user approval.**
+
+When changes are ready to be committed:
+1. Make the code changes
+2. Show the user what will be committed (git status/diff)
+3. **Wait for explicit approval** from the user before running `git commit` and `git push`
+4. Only proceed with commits when the user says "commit and push" or similar
+
+### Commit Message Format
+
+Use the following format for commit messages:
+
+```
+<Short description of changes>
+
+<Optional longer description with bullet points>
+- Detail 1
+- Detail 2
