Code Change Validator

Validate code changes by analyzing diffs, running existing tests, performing exploratory testing, and writing regression tests for any issues discovered.

Workflow

1. Analyze the diff → Understand what changed
2. Determine intent → Use conversation context or ask the user
3. Find run instructions → Locate README, Makefile, package.json, etc.
4. Build the project → Compile/build before testing to catch build errors early
5. Run existing tests → Execute the project's test suite
6. Exploratory testing → Manually verify the changed behavior
7. Write regression tests → If issues found, add tests with descriptive comments

Step 1: Analyze the Git Diff

git diff HEAD~1   # or git diff main, git diff --staged, etc.
