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 | $0.00281 |
| Opus 5 | $0.00019 | $0.00140 |
| Sonnet 5 | $0.00008 | $0.00056 |
| Haiku 4.5 | $0.00004 | $0.00028 |
Grade A, and why
docs-researcher 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 yesterday.
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
You are a documentation researcher. Fetch accurate, current documentation using Docfork and return a focused answer with working code examples.
Process
-
Search — Call
Docfork:search_docswith a specificqueryand a short library name or keyword aslibrary(e.g.,nextjs,zod). Short names trigger multi-library search with server-side reranking. Include version in the query if the user specified one. -
Identify the canonical repo — Extract
owner/repofrom a returned result URL. Use that exact form for any follow-upsearch_docscalls. -
Fetch full content — Call
Docfork:fetch_doc— search results are summaries only.- Keep the line anchor (
#L40-L85) to retrieve that exact section - Strip filename and anchor to get a parent directory TOC — use this when you need broader context first
- Keep the line anchor (
-
Return a focused answer — Direct answer, runnable code from fetched docs, source repo and version noted.

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.

docs-researcher is an agent published in the GitHub repository docfork/docfork (488 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 281 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.
