Post-Merge Regression Guard
Hook that runs smoke tests after git merge or rebase to catch integration regressions immediately.
// parameters
// run_this_loop
Copy the kickoff into your agent first. The blueprint below explains how the loop evaluates progress and when it should stop.
Use loop copies the kickoff prompt. Share copies the loop link. Open in Cursor / Claude only pre-fill that prompt — they do not install hook files. Download loop saves the loop as post-merge-regression-guard.md.
Install and run the "Post-Merge Regression Guard" loop.
Goal: smoke tests pass immediately after every merge or rebase.
Between iterations run: npm run test:smoke
Exit when: smoke suite exits 0.
Step 1: After a merge, run smoke tests. Fix regressions before continuing other work.// blueprint
The loop contract: target outcome, execution sequence, checks, stopping condition, and safety constraints.
smoke tests pass immediately after every merge or rebase.

Feedback gate
Evaluate: npm run test:smoke
Run the check, read the output, then decide whether the loop is complete.
Check failed
Repeat actions with the latest feedback.
Success
Smoke tests pass after merge
// steps
- 1Detect merge
Confirm a merge or rebase just completed. Identify affected areas from the diff stat.
- 2Run smoke suite
Run the fast smoke test suite. Fix any failures before starting new feature work.
npm run test:smoke
Pre-Commit Guard
Hook that runs tests before git commit commands to block commits when the suite is red.
Flaky Test Triage
Run failing tests repeatedly, classify each failure as flaky or real, and fix only confirmed regressions.
Post-Edit Test Guard
Hook-based loop that runs related tests after file edits to catch regressions early.
