Description
Reduce regressions by discovering tests, running them, then editing code

Test-First Change Skill

Purpose

Ensure code changes don't introduce regressions by forcing test discovery and execution before modifications.

Process

  1. Discover existing tests for target code
  2. Run tests to establish baseline
  3. Make code changes
  4. Re-run tests to verify
  5. Log changes to memory

Scripts

  • run_tests.sh: Execute test suite with coverage
  • diff_summary.py: Generate change summary for memory

Safety

  • Never edit code before running tests
  • Quarantine flaky tests
  • Require 80%+ coverage on changes
