Systematic debugging with a mandatory hypothesis preflight — no code changes before evidence; one change at a time, then a regression test. Use for any bug, test failure, or unexpected behavior.

TDD engine and enforcer — red/green/refactor, one behavior at a time. Use while implementing any feature or bugfix, or to execute a specific blueprint task with TDD.
Skill Claude CodeCodex
Compose and run a large delivery as ONE pipeline with magician's guardrails — for big multi-item work ("implement these N stories/tickets", "deliver the epic", "migrate X across the codebase", batch/sweep). Adaptive structure, but always TDD per unit, kg grounding, certify, multi-lens review + adversarial verify…
Agent
Correctness reviewer for a code change — finds bugs, logic errors, and edge cases. Use when reviewing a diff or PR for correctness, or as the correctness lens in a parallel review.
Agent
Security reviewer for a code change — finds vulnerabilities and attack surfaces (OWASP Top 10, secrets, injection, authz). Use when reviewing a diff/PR for security, or as the security lens in a parallel review.
Agent
Simplification reviewer for a code change — finds over-engineering, premature abstraction, and unnecessary complexity. Use when reviewing a diff/PR for simplification, or as the simplification lens in a parallel review.
Agent
Test/verification reviewer for a code change — ensures correctness is proven, not assumed (coverage, edge cases, meaningful assertions). Use when reviewing test quality for a diff/PR.
