security-review

security-review is a skill for Claude Code, Codex from Dark-Alex-17/coyote. It costs 100 tokens per session (2,081 once invoked), scanned C, original, AGPL-3.0.

A security review of code changes that traces outside input through the code to look for exploitable flaws. It checks issues such as injection, leaked secrets, broken access control, unsafe data handling, path traversal, and server-side request forgery.

In plain words
What is it for?
Use it to review a code diff for security problems and receive a pass-or-fail assessment.
Why use it?
It provides a structured security check before a change is accepted, with the review standard adjusted for the project's security posture.

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 C, and why

security-review scanned grade C with 3 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 10d 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.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

Every finding MUST cite file:line and name the concrete attack path or hazard. "This might be insecure" is noise; `🟠 Path traversal — export.rs:88 — 'name' from the HTTP body is joined into the output path with no canon

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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-review is a skill published in the GitHub repository Dark-Alex-17/coyote (57 stars, last pushed today), licensed AGPL-3.0. It adds 100 tokens to every session and 2,081 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 3 findings (reaches for credential files, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
