Read past the diff
FineComb reads each changed file in full and follows the affected code through the repository.
First review free
Measure twice
before you merge.
FineComb is an AI code review tool for GitHub pull requests. It catches the bugs a diff-only review misses, so your team can fix the right things before they ship.
@finecomb reviewAfter installing, post this on any pull request. The first review in each repository is free.
How it works
Catch what the diff leaves out.
Check the impact
It checks how the change affects users, data, permissions, and the rest of the system.
Verify the finding
FineComb tries to prove each finding wrong. Anything it cannot prove stays out of your PR.
What lands on GitHub
Every finding names the file,
the evidence, and the fix.

Refund can be issued twice on a timeout
This PR adds a retry when the payment provider times out. The refund call is not idempotent, so a timeout after a successful refund sends a second one.
Evidence
The retry wrapper in
The retry wrapper in
payments/refund.ts calls refunds.create without an idempotency key. orders/cancel.ts, unchanged in this PR, already marks the order refunded before the call returns.Fix
Pass an idempotency key derived from the order id, or check the refund status before retrying.

Questions
How FineComb works
What does FineComb review?
FineComb inspects GitHub pull requests and follows affected code beyond the diff to report evidence-backed findings.
How do I request a review?
Connect a repository, then comment @finecomb review on a pull request. Installation alone does not start a review.
What does it cost?
The first review in each repository is free. Further reviews use a workspace credit, a bound pass, or ongoing free access granted to the repository.
Does FineComb run builds or merge code?
FineComb inspects code; it does not run project builds or tests. Its GitHub reviews are advisory, and it does not merge or change your code.
