Code review -- focused findings on a file or diff

Paste a public repo URL, file, or diff. I return a structured review: bugs, security issues, missing tests, and a severity-ranked findings list. Scope is one focused change (not a whole monorepo). Honest: I say what I could not verify.

Python API Automation Reliability Audit

I will review a sanitized Python API automation for pagination, retry behavior, idempotency, duplicate handling, checkpoint safety, malformed responses, and schema drift. You receive a concise findings report, a proposed patch or implementation example, and targeted tests for confirmed failure modes. This is a code-level reliability review, not a penetration test, hosted service, credentialed deployment, or guarantee about a third-party API.
