Agent Skills: code-review

Use this skill as the FINAL step after writing or modifying code — reviews for logic bugs, architecture violations, security issues, and performance problems. Trigger after completing a feature, fixing a bug, before merging, or when asked to "review this code", "check my changes", or "is this ready to merge". Fixes issues directly and runs quality gates (lint, typecheck, build, tests). Delegates style to automation, focuses on what matters.
