explain-changes

Review the recent changes and provide:

1. Summary: What was built or changed? Explain in 2-3 sentences.

2. Files changed: List the files that were added or modified, grouped by area (e.g., API routes, components, database, utils).

3. Security check:

   • Any new API endpoints? Are they properly authenticated?
   • Any database writes? Is the input validated?
   • Any external API calls? Are secrets handled correctly?
   • Any user-facing inputs? Are they sanitized?

4. Risk areas: Which files or functions are most likely to cause problems? Why?

5. Edge cases: What scenarios might break this? What hasn't been tested?

6. Missing pieces: Based on what this feature is supposed to do, is anything obviously incomplete or not wired up?

7. Questions for me: Anything you're uncertain about or made assumptions on that I should verify?

Be concise. Flag problems, don't over-explain things that are fine.
