security-review

security-review is a skill for Claude Code from forest6511/claude-code-recipes-v2. It costs 16 tokens per session (208 once invoked), scanned A, original, MIT.

A security-focused code review for staged changes or another specified target. It checks common ways code can be attacked, such as injection, weak access controls, exposed secrets, and unsafe encryption.

In plain words
What is it for?
Reviewing code for input-validation flaws, authentication and authorization mistakes, leaked secrets, unsafe cryptography, request-forgery risks, path traversal, and vulnerable dependencies.
Why use it?
It helps find security problems before code is merged or released. Findings are grouped by the OWASP Top 10, a commonly used list of major web application risks, and ranked by severity.

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-review 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 8d 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.
