| # CodeRabbit rate-limits per developer; when it does, it posts a "Review limit | |
| # reached" comment and only retries on its own after the stated cooldown, or | |
| # when someone explicitly comments "@coderabbitai review". If nobody pushes a | |
| # new commit to a stalled PR in the meantime, that comment just sits there | |
| # forever. This is the backstop: on our own PRs, if the *last* CodeRabbit | |
| # comment is a rate-limit notice and we haven't already nudged it since, poke | |
| # it with "@coderabbitai review" so it wakes up on its own schedule instead of | |
| # waiting for a human to notice. | |
| # | |
| # Scope is deliberately narrow: only PRs opened by the repo owner, or PRs that | |
| # carry a "Co-Authored-By: Claude" trailer in any commit (our own automated | |
| # work) — not every open PR in the repo. | |
| on: | |
| schedule: | |
| # Hourly, not more often: CodeRabbit's own cooldown is ~an hour, so a tighter | |
| # loop would just burn its rate-limit window (or push us into usage-based | |
| # billing) without getting reviews any sooner. Offset from the hour boundary: | |
| # scheduled runs queue up right at :00 across all of GitHub, so a few minutes | |
| # off reduces the chance of a delayed run. | |
