security-reviewer

security-reviewer is a skill for Claude Code, Codex from foryourhealth111-pixel/Vibe-Skills. It costs 62 tokens per session (452 once invoked), scanned A, original, Apache-2.0.

A security-audit skill for checking code for common web risks such as leaked secrets, authentication flaws, injection, unsafe input handling, XSS, SSRF, and exposed sensitive data.

In plain words
What is it for?
It helps review authentication, authorisation, APIs, database queries, uploads, external calls, logging, and dependency risks using OWASP-style checks.
Why use it?
It helps identify security weaknesses that can let attackers bypass access controls, run unwanted actions, or see information they should not access.

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-reviewer 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 9d 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-reviewer (Codex Compatibility)

Use this skill after code changes that touch input handling, auth, APIs, data access, uploads, payments, or external integrations.

Routing Boundary

Use this skill when security is the main question:

  • OWASP/security audit/security review
  • secret leak, token exposure, unsafe logging
  • auth bypass, authorization gaps, session/token handling
  • injection, XSS, SSRF, unsafe file upload or command execution

Do not use this as the default owner for ordinary maintainability review. If security is only one item in a general PR review, code-reviewer can flag it, but explicit security-audit wording should route here.

Security Review Workflow

  1. Initial Scan
  • Locate auth, API endpoints, DB queries, file handling, and external calls.
  • Check for hardcoded secrets and unsafe config defaults.
  1. OWASP-Oriented Checks
  • Injection: parameterized queries, sanitized inputs.
  • AuthZ/AuthN: enforce authorization per route, secure session/token handling.
  • Data exposure: secrets/PII protection and safe logging.
  • XSS/SSRF: output encoding, URL allowlist, no blind fetch of user URLs.
  • Dependency risk: audit vulnerable dependencies.
  1. High-Risk Pattern Audit
  • Hardcoded secrets/tokens
  • Command execution with user input
  • SQL string concatenation
  • Missing auth check
  • Missing rate limiting on sensitive endpoints
  • Unsafe crypto/password handling
  1. Remediation Output
  • Severity (CRITICAL/HIGH/MEDIUM/LOW)
  • Evidence (file + line + risk)
  • Concrete fix proposal
  • Verification steps after fix

Vibe Integration

  • Security gate skill usable at any grade.
  • Pair with security-best-practices for language/framework-specific guidance.
  • Pair with code-reviewer for combined correctness + security review.

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.
