Watched GitHub pull requests updated their checks only on the 2-minute sweep, because GitHub's event-stream preview had no CI event. The preview added one on Nov 12: com.github.pull_request.check_suite.status.changed.v1, sent when a check suite on the head commit completes.

The event subscription now asks for it. Each event already makes the watcher re-read the PR's summary. That summary counts check runs by state, so a completed suite wakes the agent's watch and refreshes open PR views right away. It updates once per suite, not per check run: a GitHub Actions workflow is one suite, so jobs that finish mid-workflow still wait for the sweep. We don't read the event's conclusion, because the re-read already gets it.

The subscription test asserts the new event type and fails without the change.

Walkthrough

The GitHub pull request event subscription adds the check-suite status-changed event type. Its comment now states that readers fetch the pull request for every event and do not use check-suite conclusions. The test expects the added event type.

Explanation

The title names the main change: watched GitHub pull requests react when a check suite completes. It matches the PR objective of adding the check_suite status event subscription that refreshes the PR summary and wakes the watcher. The conventional commit format is also used. The title is specific and does not misrepresent the change.

Full details: Description check

Explanation

The description covers the problem (watched PRs update checks only on the 2-minute sweep), the change (subscribing to the check_suite status event so the PR summary is re-read), and the limits of the fix (once per suite, not per check run; conclusion not read). It also states that the subscription test asserts the new event type. The template's Scope section is not addressed: the author does not link an issue, does not say why none is needed, and the PR is a feature rather than a bug fix, which the template says is not accepted. The Verification section gives only a brief test note and no observed results from running the tests or any manual check. The AI-agent attribution line is present.

Resolution

Rewrite the description to follow the template headings: Problem, Change, Scope, Verification. In Scope, link the issue that shows the bug, or explain why no issue is needed. If a maintainer requested the work, link that request. The template says bug fixes are accepted and features are not, so state why this change is a bug fix and not a feature. In Verification, list the focused tests run and their observed results, such as the subscription test passing with the change and failing without it. State anything not checked. Keep the agent and model attribution at the end, as the template asks.
