security-review

security-review is a skill for Claude Code, Codex from ASMN-96/ai-agents-skills-toolkit. It costs 57 tokens per session (389 once invoked), scanned A, original, MIT.

A security-review guide for checking application and development-tool work for problems involving access control, private data, secrets, outside sources, and supply-chain risks.

In plain words
What is it for?
Use it to review authentication, permissions, tenant separation, public and private data, secrets, external tools, and the safety of dependencies.
Why use it?
It provides a consistent way to identify security concerns while avoiding unapproved scans, configuration changes, or exposure of credentials.

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 12d 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 it actually says

Security Review

Use this as the canonical final security review skill for application and toolkit work.

This skill is a review and routing layer. It does not authorize production scans, secret access, policy weakening, external installs, CI edits, MCP setup, global config changes, or tool activation.

Review Focus

  • Trust boundaries, auth, authorization, public/private payloads, and tenant data are explicit.
  • Secrets, tokens, credentials, cookies, and private environment values are not exposed.
  • External sources and tools remain untrusted until reviewed.
  • Tenant isolation, RLS, API payloads, source safety, and supply-chain metadata are checked when in scope.
  • Metadata-only tool records, skipped scans, dry-runs, unavailable scanners, and partial reviews are labeled honestly.
  • Route application security readiness through .ai-toolkit/methods/security/application-security-readiness.md. Canonical toolkit source: methods/security/application-security-readiness.md.

Tool Boundaries

Use scanner metadata only as routing intelligence unless the target project already owns the scanner command or the owner separately approves a scoped scan. Do not use Socket, ZAP, Harden-Runner, deep secret scanners, CI permission changes, or production-impacting scans without explicit approval.

Route WebView, native bridge, token/cookie, deep-link, local-file, and embedded-content risks through .ai-toolkit/methods/security/webview-boundary-review.md. Canonical toolkit source: methods/security/webview-boundary-review.md.

Completion Evidence

Report findings by severity, coverage, commands run, skipped checks, WARN output, and residual security risk.

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.
