Keep Agent Pull Requests Blocked Until Every Required Check Passes

2026-10-27

Maestro’s take. Make “ready to merge” mean every required check passed on the current commit. An agent needs an explicit answer when checks are pending or missing.

TL;DR

In its October 26 engineering account, Kiro describes an automated review-and-fix loop for Kiro Crew.

The team added one PR Readiness check to combine many CI results. Its key requirement: every expected action must have run and passed. On a new pull request, an empty set of results can otherwise look just as clean as a fully tested change.

Kiro says its prepare-pr skill reads that verdict, investigates failures, fixes real findings and pushes another revision. CI then evaluates the new revision. These are the team’s reported practices, not an independent reliability test.

Why Maestro users care

Agents can move a pull request through several revisions while checks finish at different times. If the coordinator treats “nothing failed” as “everything passed,” it can stop before the evidence exists.

Maestro’s rule: define the required evidence first. Tie each result to the commit it tested. Keep readiness blocked while a required result is pending, absent or inconclusive. Decide explicitly whether any skipped check is acceptable.

A readiness signal should help an agent finish its work. It should not silently grant permission to merge or deploy.

One thing to try

Open a harmless test pull request and deliberately leave one required check pending. Confirm your coordinator keeps it blocked. Then push a new commit and confirm a passing result from the old commit cannot clear the new one.
