The review agent stopped with 429 when the subscription token reached its weekly limit. When the first run fails, the job now runs the agent again with the PULLFROG_OAUTH_FALLBACK secret, if it is set; when neither run succeeds the check still fails, as before. The review is not a required check, so a red run does not block a merge. The provider keys move to the job's env so both runs share them.

Narrows what the job-level `env` block exposes. Hoisting the whole set put every provider token in the environment of `actions/checkout` and of the final `run:` as well, where none of them is used — and this file is otherwise careful about exactly that: `persist-credentials: false`, `push: disabled`, `shell: restricted`. Only `HAS_OAUTH_FALLBACK` has to be at job level, because only an `if:` reads it and the `secrets` context is unavailable there; the `env` context is, which is what makes the flag work. So: the flag stays at job level, the thirteen provider keys go back onto the agent step, and the fallback step carries only the fallback token. If another provider were configured and usable the first step would already have reached it, since Pullfrog walks its credentials in order, so duplicating the full set onto the second step would widen the token surface without changing an outcome. This also makes the file byte-identical to the one in pinakes-docker and Pinakes-Android, where the behaviour was verified by dispatching it rather than by reading it: the first step failed with the 429, the fallback step ran and succeeded, the verdict step was skipped, and the job reported green. A rescued run does not leave a red check behind — which was the open question about this shape. One trap the run surfaced, worth knowing before reading a future log: with `continue-on-error`, a failed step is reported as `success` in the step list, because that input rewrites the step's `conclusion`. Only `outcome` keeps `failure`. The `if:` conditions here read `outcome`, so they are correct, but the step list alone tells the opposite story.

✅ No new issues found. The step gating is correct and can merge as-is. Two informational notes are below.
Reviewed changes
There was no earlier Pullfrog review on this PR, so this run covers the whole PR (both commits).
- Fallback attempt: Adds a second
pullfrog/pullfrogstep that runs on the same pinned SHA withpush: disabled/shell: restricted. Its only provider credential isCLAUDE_CODE_OAUTH_TOKENfromPULLFROG_OAUTH_FALLBACK, and it runs only when the primary step failed and that secret exists. - Secret presence flag: Exposes only a boolean
HAS_OAUTH_FALLBACKat job level, because a stepif:cannot readsecrets. The provider keys stay scoped to the agent steps. - Failure restored: The primary step now has
continue-on-error: true. A final step exits 1 when the primary failed and the fallback was skipped. When the fallback itself fails, the job is already red, and the implicitsuccess()correctly skips the final step.
ℹ️ The fallback runs after any primary failure, not only a rate limit
The action's only output is result, so steps.agent.outcome == 'failure' cannot tell a 429 apart from other failures. These include the default 1h timeout, or an error after the review was already posted. In those cases the fallback runs the full review again: up to roughly twice the runtime, possibly a duplicate review or progress comment, and quota spent on the second account for a failure the token cannot fix. That is acceptable if 429s are by far the most common failure. It's noted here so the trade-off is a deliberate choice.
Technical details
# The fallback can't tell a rate limit apart from other failures
## Affected sites
- .github/workflows/pullfrog.yml:152 — `if: steps.agent.outcome == 'failure' && env.HAS_OAUTH_FALLBACK == 'true'`
## Required outcome
- Decide whether a second full attempt is acceptable on failures a different token can't fix (timeouts, failures after posting).
## Open questions for the human
- Should the fallback step get a tighter `timeout-minutes`, or a lower `timeout` input, so a hung primary run doesn't lead to a second 1h run?ℹ️ The PR description no longer matches the change
The description says the provider keys move from the step's env to the job's, so both runs share them. Commit 171f360 reverted that, and the keys now stay on the primary step only. Updating that bullet will keep the merge record accurate.

This run covers the two commits pushed after the prior Pullfrog review at 171f360.
- Bounded attempts: Both agent steps now pass
timeout: 20m, and the job hastimeout-minutes: 45. The pinned v0.1.90action.ymldocumentstimeoutas a duration such as10mor1h30m. A hung primary run can no longer lead to a second full 1h run. If the two attempts plus setup ever exceed 45 minutes, GitHub cancels the job and it still reports red. - Retry trade-off documented: The comment above
agent_fallbacknow states that the retry fires on any failure, not only a 429. It also says that this can spend fallback quota or repeat a review. This settles the earlier informational note as a deliberate choice. - Credential ordering cited: The comment links to the runtime's
credentialPool.tsfor the claim that the workflow OAuth token is tried before account tokens of the same kind. One caveat: the action SHA pin doesn't pin the runtime. This run reports runtime0.1.98under the same v0.1.90 pin, so "verified in 0.1.97" is a point-in-time claim. - PR description: The description now matches the per-step key scoping from
171f360.

- Fallback keeps provider keys:

If a non-Claude model is configured, the retry can still use its key. The keys are still kept out of the job-levelenv, the checkout step and the finalrun:step. - Comment updated: The comment above the step now describes the mirrored configuration. It replaces the earlier "only the fallback token" explanation.

When the primary review attempt fails, Pullfrog now makes one additional attempt using
PULLFROG_OAUTH_FALLBACK, if configured. A review that cannot run still fails the check. Provider keys remain scoped to the two agent steps. The fallback retains the same provider keys and replaces only the OAuth token; job-level environment contains only its presence flag.The runtime 0.1.97 credential selector tries the workflow OAuth token before account OAuth tokens of the same kind; its stable subscription sort retains that order. This is verified in the published npm package and its matching credentialPool.ts source. API keys are not claimed to outrank subscriptions. Read-only repository permissions, disabled push, restricted shell and checkout without persisted credentials are retained.
The action exposes
result, not a structured failure reason, so the retry applies to any primary failure rather than only 429s. Both attempts are capped at 20 minutes and the job at 45 minutes. A deterministic error may spend fallback quota, and an error after posting may duplicate a review; the workflow comment makes this bounded trade-off explicit. A clean replay after late side effects is not claimed.Validation: actionlint and diff whitespace checks pass. The previously quota-failed review was rerun. All 35 checks pass on final head

This matches the action-version corrections already present in the application PR.Bot review audit (8 October 2026): CodeRabbit’s outside-diff finding about fallback provider keys is implemented, and Pullfrog’s follow-up reports no new issues.
