What is security-review?

A code-security review guide that checks code changes, pull requests, or services for risks an attacker could exploit.

Use it to review authentication, user input, secrets, APIs, data handling, concurrency, containers, third-party software, and dependencies. It supports reviews of Node.js and TypeScript, Java and Spring, and Python web applications.

It helps find serious security problems before code is merged or deployed, while filtering out issues that are not practically exploitable.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 271
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00164	$0.06111
Opus 5.5	$0.00066	$0.02444

Security

Grade A, and why

security-review scanned grade A with 2 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 1mo ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/eval_ab.py, scripts/eval_live.sh, scripts/report_validator.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

`init()` unprompted, `curl*` covers `curl -o <file>` and `curl -d @<file> <host>`, `npm audit*`

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

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

Security Review

Find exploitable risks early, provide concrete fixes, and keep recommendations practical for engineering delivery.

Review Principles

Prioritize exploitable risk over style issues.
Ground every claim in code/config/runtime evidence.
Distinguish confirmed vulnerabilities from hypotheses.
Provide reproducible proof for high-risk findings.
Map findings to standards for auditability.
If evidence is missing, state Not found in repo.
Fail closed: if a mandatory gate cannot be executed, state it explicitly and do not claim full coverage.
Authorization before action: static review always; touching a running system only under §Active Verification Authorization Gate. Default deny.
Execution integrity: never present a command you did not run as if you had. Label unexecuted reproducers explicitly.

Evidence Confidence (Mandatory)

Each finding must include one confidence label:

confirmed: vulnerable path proven by code and/or reproducible execution.
likely: strong evidence with one missing runtime assumption.
suspected: weak evidence requiring additional data.

Changes

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 johnqtcg/awesome-skills (30 stars, last pushed 18d ago), licensed MIT. It adds 164 tokens to every session and 6,111 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Run the adversarial verification loop — implement, then hand the change to a fresh checker that did not write it, fix what it finds, and re-dispatch until APPROVE. Use before claiming any behavioural change is done, and on requests like "review loop", "adversarial review", "independent review", "get this verified"…
