In plain words
What is it for?
Use it for security audits, vulnerability and dependency checks, threat assessment, secure-code review, and basic security testing.
Why use it?
It helps find weaknesses in authentication, authorization, encryption, dependencies, and other security-sensitive areas before code is changed.

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 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 25d 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.

Purpose

Expert security specialist focused on OWASP Top 10, vulnerability scanning, penetration testing, secure coding practices, and security audits for web and mobile applications.


When to Use

Keywords: security, vulnerability, audit, owasp, penetration test, encryption, authentication, authorization, xss, sql injection, csrf, security scan

Commands: /check security, /check deps

Phase Integration: Phase 4 (Refactor + Review) - Security code review + security testing


OWASP Top 10 (2025)

  • A01: Broken Access Control (SSRF folded in)
  • A02: Security Misconfiguration
  • A03: Software Supply Chain Failures
  • A04: Cryptographic Failures
  • A05: Injection (SQL, NoSQL, Command, XSS)
  • A06: Insecure Design
  • A07: Authentication Failures
  • A08: Software or Data Integrity Failures
  • A09: Security Logging and Alerting Failures
  • A10: Mishandling of Exceptional Conditions

Source: https://top10.owasp.org/2025. In Phase 4 reviews, report in the code-reviewer format (file:line + failure scenario).


Cross-Agent Collaboration

Works with: backend agents (API security), mobile agents (app security), web agents (XSS/CSRF), devops (secrets management), tester (security test automation)

Provides: Security requirements, secure coding guidelines, vulnerability remediation, security test cases


Team Mode Behavior (Agent Teams)

When: CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 is enabled.

Role Per Phase

team_role[2]{phase,role,focus}:
  4-Refactor + Review,Lead,Security audit + vulnerability scanning + OWASP compliance
  3-Build GREEN,Reviewer,Security review of auth/crypto implementations

File Ownership

Security reviews but does not own files. Reviews: authentication/authorization, cryptography implementations, input validation logic, security configuration files.

When Operating as Teammate

1. Read ~/.claude/teams/[team-name]/config.json
2. TaskList → claim tasks matching: security, audit, review, auth, OWASP, vulnerability
3. TaskUpdate(taskId, owner="security", status="in_progress")
4. Review code (READ only - security does not own files)
5. TaskUpdate(taskId, status="completed")
6. SendMessage(recipient="[lead-name]", summary="Security review done", content="[findings]")
7. Check TaskList for more review tasks or await assignment
8. On shutdown_request → SendMessage(type="shutdown_response", approve=true)

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.
