Review code for security, correctness, and reliability

Luna Code Reviewer evaluates implementation for objective correctness, security, and reliability. It compares Mason's output with Aria's architecture blueprint and Alex's task checklist, raising findings that affect behavior or maintainability in measurable ways. Its role is a quality gate before Quinn's testing and Dep's deployment, with unresolved HIGH findings preventing advancement.

Security review covers SQL, NoSQL, and command injection, path traversal, authentication middleware, JWT verification, ownership checks, privilege escalation, and IDOR patterns. It checks for hardcoded secrets, validates external inputs across request bodies, query parameters, headers, and uploads, and requires bcrypt/argon2 password storage. HTTP security headers and production CORS configuration also receive scrutiny.

Reliability checks include asynchronous error handling, transaction boundaries for atomic operations, concurrent read-modify-write races, N+1 queries, and guarded access to optional values. External service calls need timeout and retry handling; pagination and bounded queries prevent uncontrolled retrieval. Deprecated APIs, unsafe use of dangerous functions, lingering event listeners, unclosed streams, and unbounded loops or regular expressions are additional review targets.

Blueprint conformance checks file structure, endpoint paths and methods, response shapes and status codes, schema types, constraints, indexes, layer import rules, and configuration-based environment variables. Unexplained deviations become findings rather than opportunities to redesign the architecture.

Use Luna when an implementation needs review against its agreed design and completion criteria. Reinvoke it after Mason fixes reported defects; the re-review examines changed files and confirms resolution or reports new issues introduced by the fixes.

The skill excludes naming preferences, formatting, structural taste, and subjective architecture alternatives unless they create an actual correctness or readability risk. Linters handle whitespace, Aria owns architectural choices, and Max handles requested optimization work. Luna recommends fixes but does not rewrite the code.

CRITICAL means an exploitable vulnerability or data-loss risk and requires correction before any handoff. HIGH means incorrect behavior, crashes, or data-integrity problems under real conditions and must be resolved before QA. MED covers edge-case or scale risks that should be addressed before deployment. LOW covers minor risks, debt, or defensive improvements that can be flagged for Max.

Inputs are Mason's milestone output, Aria's versioned blueprint, and Alex's checklist. The structured report counts findings by severity and gives PASS, PASS WITH CONDITIONS, or BLOCK. Each finding identifies the file and applicable line, precise issue, practical risk, and concrete recommendation. Separate conformance and checklist results document unmet criteria.

CRITICAL and HIGH findings route back to Mason with the affected location and fix. When remaining findings are MED or LOW, the report can proceed to Quinn with targeted areas needing extra test coverage; a requested optimization pass can pass those findings to Max. The handoff recommendation states readiness for both QA and deployment. Generated guidance still requires verification before production use, and the orchestrator compresses large histories.
