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 | $0.00031 | $0.03237 |
| Opus 5.5 | $0.00012 | $0.01295 |
| Sonnet 5.5 | $0.00006 | $0.00647 |
| Haiku 4.5 | $0.00003 | $0.00324 |
Grade A, and why
inspect-ai-context 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context navigator (multi-source)
Overview
This navigator catalogs references for multiple sources the engine has been pointed at. Each source's references are catalogued in their own ## Catalog: <source-slug> section below; references live in references/<source-slug>-<topic>.md so the filename prefix discriminates sources at-a-glance.
The navigator's standing instructions stay small; references load only when relevant to the current question. The catalog itself is a TOC and is excluded from the standing-instructions budget, so additional sources and rows can be added without trimming prose.
When asked a question:
- Identify which source the question is about — see "How to search this navigator" below.
- Scan that source's Catalog section for the matching topic.
- Follow the link to read the reference file.
- If the question spans multiple sources, consult the Cross-source map.
Claims policy
Cite by default, and make load-bearing claims verifiable:
- Inline-cite every load-bearing claim with its SHA-pinned permalink — the
https://github.com/<owner>/<repo>/blob/<sha>/<path>#L<start>-L<end>link the reference gives for that fact (versions, defaults, signatures, deprecations, behavior a user could get wrong by guessing). Put the permalink inline, on the claim. Use a bare filename parenthetical (e.g.(<source-slug>-<topic>.md)) only when the reference genuinely provides no permalink. This inline permalink is what the grounded-citation eval (SELF-AUDIT Check 8) grades. - Don't cite orientational prose — "what is X?", "when did X launch?" — answer those from this navigator alone; opening a reference is itself a citation gesture.
- End with a one-line provenance footer, emitted italic, formatted
*References consulted: foo.md, bar.md. Grounded in {{LIBRARY}}@{{VERSION}} — [reference index]({{INDEX_URL}}).*The footer is a summary of what you read — not a substitute for the inline permalinks on the claims. Tokens are agent-substituted at answer time (they appear literally in the stampedSKILL.md); across multiple sources,{{LIBRARY}}resolves to the source slug(s) the answer drew from, or every registered slug when no reference was opened. - If no reference was opened, say so in the footer ("Answered from general knowledge — no {{LIBRARY}} references consulted") — never fake it.
What ships with it
23 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.

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.

inspect-ai-context is a skill published in the GitHub repository nick-railsback/skill-engine (2 stars, last pushed 21d ago), licensed MIT. It adds 31 tokens to every session and 3,237 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
