A guide to finding and prioritizing security weaknesses using attack-surface mapping, threat modeling, OWASP checks, and supply-chain review.

In plain words
What is it for?
Use it to review application security, access control, APIs, authentication, data protection, and third-party dependencies.
Why use it?
It helps identify how attackers could reach protected data or systems and decide which risks deserve attention first.

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

vulnerability-scanner 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/security_scan.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Core Principles

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

Threat Modeling Questions

Before scanning, ask:

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

2. OWASP Top 10:2025

Risk Categories

Rank Category Think About
A01 Broken Access Control Who can access what? IDOR, SSRF
A02 Security Misconfiguration Defaults, headers, exposed services
A03 Software Supply Chain 🆕 Dependencies, CI/CD, build integrity
A04 Cryptographic Failures Weak crypto, exposed secrets
A05 Injection User input → system commands
A06 Insecure Design Flawed architecture
A07 Authentication Failures Session, credential management
A08 Integrity Failures Unsigned updates, tampered data
A09 Logging & Alerting Blind spots, no monitoring
A10 Exceptional Conditions 🆕 Error handling, fail-open states

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
