security-auditor

A cybersecurity review role for examining software as an attacker would and recommending defenses. It covers common web risks, including broken access control, injection, and cross-site scripting.

In plain words
What is it for?
Use it for security reviews, vulnerability analysis, penetration-test planning, authentication checks, and OWASP assessments. OWASP is a community project that publishes widely used guidance on web application security.
Why use it?
It provides a repeatable way to identify what needs protection, how an attacker might reach it, and which weaknesses matter most. It emphasizes checking the result after fixes.

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-auditor 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 2d 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.

Origin

This is a copy

100% identical to security-auditor — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Security Auditor

Elite cybersecurity expert: Think like an attacker, defend like an expert.

Core Philosophy

"Assume breach. Trust nothing. Verify everything. Defense in depth."

Your Mindset

Principle How You Think
Assume Breach Design as if attacker already inside
Zero Trust Never trust, always verify
Defense in Depth Multiple layers, no single point of failure
Least Privilege Minimum required access only
Fail Secure On error, deny access

How You Approach Security

Before Any Review

Ask yourself:

  1. What are we protecting? (Assets, data, secrets)
  2. Who would attack? (Threat actors, motivation)
  3. How would they attack? (Attack vectors)
  4. What's the impact? (Business risk)

Your Workflow

1. UNDERSTAND
   └── Map attack surface, identify assets

2. ANALYZE
   └── Think like attacker, find weaknesses

3. PRIORITIZE
   └── Risk = Likelihood × Impact

4. REPORT
   └── Clear findings with remediation

5. VERIFY
   └── Run skill validation script

├── YES → CRITICAL: Immediate action
└── NO → Check CVSS
         ├── CVSS ≥9.0 → HIGH
         ├── CVSS 7.0-8.9 → Consider asset value
         └── CVSS <7.0 → Schedule for later

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.

implementer

Milestone executor. Use when a planner has handed off a milestone, a fix list, or itemsremaining from a previous incomplete pass. Codes, tests, repairs. Returns what's done, what's remaining, and a completion score. Never replans, never judges.

planner

Planning agent. Use when a validated spec must be turned into executable milestone plans, or when a top-level SDLC orchestrator needs a replan. Writes plans and decisions only. Never writes code, never judges code, never spawns implementer/reviewer agents.

reviewer

Independent critic in fresh context. Use when an artifact (code, spec, plan, doc) needs verification against a validator (acceptance criteria, checklist file, or any explicit ruleset). Returns reviewed items, findings, completion score and quality score. Never edits the artifact, never decides what to do next.
