Verification Pack
- Updated July 30, 2026
- s-hiraoku/claude-harnesses
verification-pack is a verification feedback loop that runs format, typecheck and tests on every edit and blocks a premature Stop until verify.sh passes. Developers use it to guarantee an agent's changes are actually verified before work is declared done.
Key points
- Format/typecheck/test on every edit
- Blocks premature Stop
