Test-First Change Skill
Purpose
Ensure code changes don't introduce regressions by forcing test discovery and execution before modifications.
Process
- Discover existing tests for target code
- Run tests to establish baseline
- Make code changes
- Re-run tests to verify
- Log changes to memory
Scripts
run_tests.sh: Execute test suite with coveragediff_summary.py: Generate change summary for memory
Safety
- Never edit code before running tests
- Quarantine flaky tests
- Require 80%+ coverage on changes
