security

security is a skill for Claude Code, Codex from DGouron/review-flow. It costs 36 tokens per session (1,004 once invoked), scanned A, original, MIT.

A code scan that looks for passwords, API keys, access tokens, and other credentials before code is committed or pushed. It can also be run on demand.

In plain words
What is it for?
Scanning a repository for GitHub, GitLab, AWS, OpenAI, Anthropic, Slack, Discord, and generic hard-coded credentials.
Why use it?
It helps catch sensitive values that could otherwise be checked into a repository and exposed to others.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security is a skill published in the GitHub repository DGouron/review-flow (42 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,004 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
