Reviewing a diff or feature for exploitable vulnerabilities before it ships. Use when asked to do a security review, when code touches auth, input handling, queries, files, URLs, crypto, or payments, and before merging changes that accept untrusted input.

Proving a change works before reporting it done, and what to do when the check fails. Use after editing code, before writing the final answer, and whenever deciding which check proves which claim.

Skill Claude CodeCodex

Current or latest information of any kind — API docs, pricing, releases, news, versions — whenever the user asks about "now", "recently", or something you cannot verify from the repo or training data. Assume the user expects up-to-date answers, so check the web rather than answering from stale knowledge. Always prefer…

Skill Claude CodeCodex

Turning a workflow this session learned into a reusable skill. Use when the user says save this as a skill or make a skill for this, when they repeat the same correction or instructions a second time, or when a multi-step procedure just worked and will clearly recur.

Installing and adding dependencies without executing an attacker's code. Use before any package install or add, when a lockfile changes, or when choosing a new dependency.
