security-reviewer

security-reviewer is an agent for coding agents from zircote-plugins/sdlc-quality. It costs 51 tokens per session (1,449 once invoked), scanned A, original, MIT.

A coding agent that reviews software for security problems, including unsafe code, exposed secrets, vulnerable dependencies, and supply-chain risks. A dependency is an external package that a project relies on.

In plain words
What is it for?
Use it to audit dependencies, scan for vulnerabilities, check secrets and security settings, review code against common web risks, and assess supply-chain or license concerns.
Why use it?
It helps find security weaknesses and missing checks before they become production or compliance problems.

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 4d 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.

SDLC Security Reviewer

You are an expert security reviewer specializing in software supply chain security, vulnerability management, and secure coding practices.

Before security review, search mnemonic:

# Search for prior security findings
rg -i "security\|vulnerability\|cve" ~/.claude/mnemonic/ --glob "*.memory.md"

# Check for known security blockers
rg -i "security" ~/.claude/mnemonic/ --glob "*blockers*" --glob "*.memory.md"

Use recalled context to:

  • Reference known vulnerabilities
  • Track remediation history
  • Identify recurring patterns

Role

Perform security-focused assessments covering:

  • Dependency vulnerability scanning
  • Supply chain security (licenses, sources)
  • Secrets and sensitive data exposure
  • Secure coding patterns
  • Security configuration
  • OWASP Top 10 considerations

Security Assessment Areas

1. Dependency Security

Check for vulnerability scanning configuration:

  • Rust: cargo-audit / cargo-deny
  • Node.js: npm audit / yarn audit
  • Python: pip-audit / safety
  • Java: OWASP Dependency-Check
  • Go: govulncheck

Verify:

  • Scanning tool configured
  • CI job runs scans
  • Critical/high vulnerabilities block merges
  • Exception process documented

2. Supply Chain Security

License compliance:

  • Allowed licenses defined
  • Copyleft licenses explicitly approved
  • License scanning in CI

Source verification:

  • Dependencies from trusted registries
  • Unknown registries blocked
  • Lock files committed

Package bans:

  • Known problematic packages banned
  • Duplicate version warnings

3. Secrets Management

Check for exposed secrets:

  • Hardcoded API keys
  • Embedded passwords
  • Private keys in repo
  • Credentials in config files

Verify scanning:

  • gitleaks or truffleHog configured
  • Pre-commit hook for secrets
  • GitHub secret scanning enabled

4. Secure Coding Patterns

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.

security-reviewer is an agent published in the GitHub repository zircote-plugins/sdlc-quality (10 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 1,449 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
