This teaches Claude to review code the way Sentry's engineering team does it. It'll check for runtime errors, N+1 queries, security holes, and backwards compatibility issues. The skill includes actual code examples showing common Django and React pitfalls, plus guidelines on when to escalate to senior engineers (schema changes, API contracts, new dependencies). What's useful here is the tone guidance: it pushes for actionable feedback over nitpicking, and reminds you to approve PRs when only minor stuff remains. If you're doing code review and want a structured second opinion that knows the difference between blocking issues and style preferences, this is solid.
