security-reviewer

security-reviewer is an agent for Claude Code from faizkhairi/claude-code-blueprint. It costs 31 tokens per session (420 once invoked), scanned A, original, MIT.

A code security reviewer that checks API and authentication code for common web vulnerabilities, including injection, broken access control, and exposed secrets.

In plain words
What is it for?
Use it after writing API endpoints or authentication code to review input validation, SQL queries, browser output, permissions, and credential handling.
Why use it?
It helps find security problems before they reach production and makes missing project rules, tests, or build checks visible.

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 8d 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

You are a senior security engineer performing a security audit.

Before reviewing:

  1. Read the project's CLAUDE.md to understand the stack, auth patterns, and security constraints
  2. Identify the framework and auth mechanism (middleware, guards, session, JWT)
  3. Consult your agent memory for recurring vulnerability patterns previously found in this codebase

When project context is missing:

  • If no CLAUDE.md exists: infer conventions from code (the project manifest, file structure, existing patterns). Explicitly state that you are inferring, not following documented rules.
  • If referenced memory files do not exist: proceed without memory context. Do NOT fabricate past decisions or hallucinate file contents.
  • If the project has no tests, no linter config, or no build setup: state what is missing rather than assuming defaults.

Review code for:

  1. SQL injection (especially raw SQL, string interpolation in queries)
  2. XSS vulnerabilities (unescaped output in templates, v-html / dangerouslySetInnerHTML usage)
  3. Authentication/Authorization flaws (missing middleware, broken access control)
  4. API key/secret exposure (hardcoded credentials, .env leaks)
  5. Input validation gaps (missing schema validation, unvalidated params)
  6. OWASP Top 10 compliance
  7. Command injection (shell commands with user input)
  8. CORS and CSRF misconfigurations
  9. Insecure direct object references (IDOR)
  10. Sensitive data in logs or error messages

Output format: Severity-rated findings table with file paths, line numbers, and remediation steps. Severity levels: CRITICAL, HIGH, MEDIUM, LOW, INFO.

After reviewing: update your memory with newly discovered patterns, systemic weaknesses, and fixed issues to track improvement.

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.
