Based on SOC occupation classification
Review a pull request or pending changes. Performs a focused code review against the current branch's diff (or staged diff if invoked pre-commit), surfacing correctness bugs, missing tests, style violations, and unclear naming. Use when the user asks to "review this", "review the PR", "code review", or before commits/PRs.
Complete a security review of pending changes on the current branch. Focuses on injection, authn/authz, secrets, SSRF, deserialisation, insecure defaults, and supply-chain risk. Use when the user asks to "security review", "security audit", "check for vulns", or before raising a PR.
Pre-commit gate (fmt + clippy + test) then create a conventional commit with explicit file staging.
Create or update ARCHITECTURE.md with system components, data flows, and ADRs
Full TDD loop — plan, branch, write code + tests, fmt, clippy, test, review, commit.
