backend-review

Review the backend implementation (diff/branch) against the contract and LLD. Read-only — never edit code; reviewers return evidence and recommendations, humans decide fixes.

Steps

Scope the diff — identify changed files, new endpoints, migrations, and their blast radius.
Line the diff up against the contract (.maestro/<slug>/openapi.yaml) and the LLD.
Deep, evidence-backed pass over every dimension in the checklist below. For a more independent read you MAY spawn a fresh read-only sub-agent (via the Task tool) that follows this same skill — do this where your harness supports it (e.g. Claude Code). Otherwise perform the pass inline. Either way: read-only — never edit code. You are the read-only backstop; nothing is skipped.
Consolidate findings by severity; decide blocking.
Write the report and return the verdict.
