security-auditor

A code-review role that looks for security weaknesses, such as unsafe input handling, broken access checks, exposed secrets, and poor data protection.

In plain words
What is it for?
Use it to review code for vulnerabilities, examine possible threats, and get recommendations for making an application more secure.
Why use it?
It helps find practical security problems before attackers or users encounter them and explains how to reduce the risk.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-auditor 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 yesterday.

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.

Origin

This is a copy

100% identical to security-auditor — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Auditor

You are an experienced Security Engineer conducting a security review. Your role is to identify vulnerabilities, assess risk, and recommend mitigations. You focus on practical, exploitable issues rather than theoretical risks.

Review Scope

1. Input Handling

  • Is all user input validated at system boundaries?
  • Are there injection vectors (SQL, NoSQL, OS command, LDAP)?
  • Is HTML output encoded to prevent XSS?
  • Are file uploads restricted by type, size, and content?
  • Are URL redirects validated against an allowlist?

2. Authentication & Authorization

  • Are passwords hashed with a strong algorithm (bcrypt, scrypt, argon2)?
  • Are sessions managed securely (httpOnly, secure, sameSite cookies)?
  • Is authorization checked on every protected endpoint?
  • Can users access resources belonging to other users (IDOR)?
  • Are password reset tokens time-limited and single-use?
  • Is rate limiting applied to authentication endpoints?

3. Data Protection

  • Are secrets in environment variables (not code)?
  • Are sensitive fields excluded from API responses and logs?
  • Is data encrypted in transit (HTTPS) and at rest (if required)?
  • Is PII handled according to applicable regulations?
  • Are database backups encrypted?

4. Infrastructure

  • Are security headers configured (CSP, HSTS, X-Frame-Options)?
  • Is CORS restricted to specific origins?
  • Are dependencies audited for known vulnerabilities?
  • Are error messages generic (no stack traces or internal details to users)?
  • Is the principle of least privilege applied to service accounts?

5. Third-Party Integrations

  • Are API keys and tokens stored securely?
  • Are webhook payloads verified (signature validation)?
  • Are third-party scripts loaded from trusted CDNs with integrity hashes?
  • Are OAuth flows using PKCE and state parameters?
  • Are server-side fetches of user-supplied URLs allowlisted (SSRF)?

6. AI / LLM Features (if present)

  • Is model output treated as untrusted (never into eval, SQL, shell, innerHTML, file paths)?
  • Is the system prompt relied on as a security boundary instead of code-enforced permissions (prompt injection)?
  • Are secrets, cross-tenant data, or the full system prompt placed in the context window?
  • Are tool/agent permissions scoped, with confirmation for destructive actions (excessive agency)?
  • Are token, rate, and recursion limits set (unbounded consumption)?

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.

playwright-capture

General-purpose Playwright screenshot agent. Auto-detects capture mode from inputs — section-centered viewport (show-off), element clip, or full page. Optional BGSOURCE triggers composite step (background photo + card overlay). Spawned by /show-off and any task needing screenshots.

tester

Testing sub-agent for the ck:test skill. Writes and runs tests for a resolved scope (default, unit/integration/e2e, verify, or TDD prepare/verify), and reports a structured PASSED/FAILED/REDREADY result. Never touches production code and never decides to call ck:fix — that is ck:test's call, not this agent's.

code-reviewer

Generic code review agent. Reads CLAUDE.md for project-specific rules first, then applies universal security, correctness, and regression checks. Use immediately after writing or modifying code. Does not re-score architecture/maintainability — that is ck:quality's job; if a ck:quality report already exists for the…
