Skill Claude CodeCodex
Web research via platform web tools. Use for technical comparisons, current-state and release-behavior questions, recent facts, ecosystem news, best practices, standards, or questions needing grounded web evidence. NOT for exact API syntax, config keys, or code examples — use looking-up-docs for those. NOT for…
Skill Claude CodeCodex
Use when reviewing changed code, PRs, diffs, or specific files. Finds evidence-backed defects in security, correctness, tests, reliability, performance, maintainability, and docs.
