security-review

security-review is a skill for Claude Code, Codex from ZeroDeng01/sublinkPro. It costs 39 tokens per session (2,144 once invoked), scanned A, original, MIT.

A checklist for reviewing changes involving authentication, permissions, secrets, personal or sensitive data, and other security-critical code. Authentication proves who a user is; authorization decides what that user may do.

In plain words
What is it for?
Use it when changing login, authorization, multi-factor authentication, secrets, database queries, cryptography, browser security settings, sessions, or file uploads and downloads.
Why use it?
It helps find security weaknesses such as bypassed permissions, improperly checked tokens, unsafe sessions, or inadequate input validation before release.

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 5d 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.

Security Review Skill

This skill provides a comprehensive security review checklist for code changes that involve authentication, authorization, sensitive data handling, or security-critical features.

When to use: When making changes to:

  • Authentication/authorization logic
  • MFA (Multi-Factor Authentication) functionality
  • Sensitive data handling (passwords, tokens, API keys, secrets)
  • API endpoints with permission requirements
  • Input validation and sanitization
  • Database queries
  • Cryptographic operations
  • CORS/CSP configurations
  • Session management
  • File upload/download functionality

Security Review Checklist

🔐 1. Authentication & Authorization

Check for:

  • Authentication bypass: Can the endpoint/feature be accessed without proper authentication?
  • Authorization checks: Are user permissions verified before allowing access?
  • Role-based access control: Are roles (admin, user, guest) properly enforced?
  • Token validation: Are JWT/API tokens properly validated (signature, expiration, issuer)?
  • Session security: Are sessions properly managed (timeout, secure flags, HttpOnly)?

Detailed guide: references/authentication-guide.md (includes code examples)

Relevant files:

  • api/auth.go
  • api/auth_mfa.go
  • middlewares/auth.go
  • middlewares/mfa.go

🔑 2. MFA (Multi-Factor Authentication)

Check for:

  • MFA enforcement: Is MFA required for sensitive operations?
  • MFA bypass prevention: Can MFA be circumvented through alternate flows?
  • Backup codes security: Are backup codes securely generated and stored?
  • TOTP secret protection: Are TOTP secrets encrypted at rest?
  • Rate limiting: Is there rate limiting on MFA verification attempts?

Detailed guide: references/mfa-guide.md

Relevant files:

  • api/auth_mfa.go
  • models/mfa.go
  • middlewares/mfa.go

🛡️ 3. Sensitive Data Handling

Check for:

  • Password storage: Are passwords hashed with bcrypt/argon2 (never plain text)?
  • Secrets in logs: Are secrets/tokens masked in logs and error messages?
  • Secrets in responses: Are sensitive fields (passwords, tokens) excluded from API responses?
  • Secrets in transit: Are sensitive data transmitted over HTTPS only?
  • Secrets in database: Are secrets encrypted at rest (API keys, tokens)?

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.
