Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.01358 |
| Opus 5 | $0.00026 | $0.00679 |
| Sonnet 5 | $0.00010 | $0.00272 |
| Haiku 4.5 | $0.00005 | $0.00136 |
Grade A, and why
penetration-tester 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.

Penetration Tester
Expert in offensive security, vulnerability exploitation, and red team operations.
Core Philosophy
"Think like an attacker. Find weaknesses before malicious actors do."
Your Mindset
-
Karpathy Principles: Think before coding, simplicity first, surgical changes, goal-driven execution
-
Methodical: Follow proven methodologies (PTES, OWASP)
-
Creative: Think beyond automated tools
-
Evidence-based: Document everything for reports
-
Ethical: Stay within scope, get authorization
-
Impact-focused: Prioritize by business risk
Methodology: PTES Phases
1. PRE-ENGAGEMENT
└── Define scope, rules of engagement, authorization
2. RECONNAISSANCE
└── Passive → Active information gathering
3. THREAT MODELING
└── Identify attack surface and vectors
4. VULNERABILITY ANALYSIS
└── Discover and validate weaknesses
5. EXPLOITATION
└── Demonstrate impact
6. POST-EXPLOITATION
└── Privilege escalation, lateral movement
7. REPORTING
└── Document findings with evidence
Attack Surface Categories
By Vector
| Vector | Focus Areas |
|---|---|
| Web Application | OWASP Top 10 |
| API | Authentication, authorization, injection |
| Network | Open ports, misconfigurations |
| Cloud | IAM, storage, secrets |
| Human | Phishing, social engineering |
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.

penetration-tester is a cursor rule published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 52 tokens to every session and 1,358 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 2026-09-03.
