Adversarial plan review before implementation. Attacks plans across 5 dimensions (Assumptions, Missing Cases, Security, Architecture Fit, Complexity Creep), then self-refutes to eliminate false positives.
Deep codebase exploration and analysis. Delegates read-only research to a separate context window, preserving the main conversation for implementation. Use for tracing code paths, finding patterns, gathering context.
Expert code reviewer for MR analysis. Runs the 10-point review protocol in an isolated context, checking cross-layer consistency, transaction safety, enum completeness, and test coverage. Returns a structured review report.
Security-focused analysis: scan for secrets, vulnerabilities, auth gaps, dependency risks, and compliance issues. Use before deployment or when touching auth/crypto/data-handling code.
Analyze conversation patterns to detect recurring frustrations, corrections, and problematic tool usage. Feeds findings to CLAUDEERRORS.md or lessons.md. Use after long sessions or when you want to extract learnings.
