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 | $0.00039 | $0.00377 |
| Opus 5 | $0.00019 | $0.00188 |
| Sonnet 5 | $0.00008 | $0.00075 |
| Haiku 4.5 | $0.00004 | $0.00038 |
Grade A, and why
pentester-knowledge-base 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.
What it actually says
Knowledge Base (runtime adapter)
Interface (sole): .agents/knowledge/LOOKUP.md + node .agents/bin/lookup.js
Phase map of knowledge: PTES-INDEX.md only
Not for phase bags: INDEX.md (pointer page only), TIER2-CATALOG.md, DIRECTORY.md, ctf-lab/
Not this skill: bulk archive import → pentester-knowledge-import
Query
node .agents/bin/lookup.js --phase ${N} --keywords "<from handoff summary>"
node .agents/bin/lookup.js --check-index
Read 3–10 returned tier-1 paths. Miss → tier-2 via TIER2-CATALOG.md / archives or web_search.

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.

pentester-knowledge-base is a skill published in the GitHub repository fb0sh/pentester (23 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 377 once invoked, about $0.0002 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 2026-08-30.
