Re-pins the shared review workflow. This is the change that actually reduces the load PR Hygiene puts on the organisation's GitHub API allowance — measured at 958 runs/day and ~50k requests/day across the five repositories before any of it.

  • Comments this engine never reads no longer start a run at all — coverage bots, other automation and human discussion were 59% of comment triggers. The test is on the event payload, so no runner starts. CodeRabbit's and thepastaclaw's comments, and anything containing /self-reviewed, still trigger immediately, edits included: CodeRabbit publishes its completion by editing the comment it opened the review with, so that had to keep working.
  • An author's five review slots are rebuilt with one GraphQL query instead of two REST requests per open pull request they have. Measured on Platform: 80 → 44 requests for one reconciliation.
  • Collaborator access is read once per run from a single listing rather than once per person.
  • The sweep runs hourly and covers six pull requests per run instead of three every fifteen minutes. Events still drive everything immediate; the sweep only repairs what events missed.

No change to who may approve, when a pull request is ready, or what blocks it.

Summary by CodeRabbit

  • Chores
    • Updated automated review policy checks to respond to newly created or edited comments.
    • Adjusted scheduled policy checks to run hourly.
    • Refined review policy conditions for approved automated reviewers and self-review comments.
    • Updated the underlying workflow version used for policy checks.

Ignores comments the engine never reads, rebuilds an author review slots with
one query instead of two requests per pull request, reads collaborator access
once per run, and sweeps hourly.

dashpay/stale_prs_are_bad#20, #21, #22 and #24 landed as c115fa43691c6de989bd224989899d44f76bab89.

The workflow now responds to created and edited comments, runs hourly at minute 17, filters policy job execution by author or command, and uses a new reusable workflow commit.

The workflow no longer responds to deleted comments. The schedule runs at minute 17 of each hour. The policy job allows selected authors or comments containing /self-reviewed. The reusable workflow reference uses commit c115fa43691c6de989bd224989899d44f76bab89.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Restrict issue-comment handling to pull requests. Qualifying comments on ordinary issues invoke the reusable workflow. Its concurrency key uses github.event.issue.number, but its reconcile job skips ordinary issue comments through github.event.issue.pull_request. Therefore, these comments do not change PR policy state, but they still create unnecessary reusable-workflow runs. Require github.event.issue.pull_request around the qualifying-comment checks before invoking the workflow. Ordinary issue comments are not intended for PR-policy reconciliation.
