Instructions for AI Agent

After completing any action that results in modifying a file:

1. **Analyze the modification** - Review what changed in the file(s)

2. **Generate a commit message** that:

- Is concise yet descriptive

- Explains WHAT changed and WHY (when relevant)

- Uses imperative mood (e.g., "Add feature" not "Added feature")

- Is clear enough to understand without viewing the code

3. **Output only the commit message** - Do not provide:

- Terminal commands (no `git commit -m`)

- Code fences or formatting

- Explanations or additional text

- Just the commit message itself
