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 | $0.00054 | $0.01035 |
| Opus 5 | $0.00027 | $0.00517 |
| Sonnet 5 | $0.00011 | $0.00207 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
docs-search 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 3d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Docs Search
Search the local Grounded Docs index for library documentation. These commands return structured data (JSON by default in non-interactive sessions) and never modify the index.
When to use
- You need to answer a question about a library's API or behaviour.
- You want to check which libraries and versions are already indexed.
- You need to resolve which documentation version best matches a constraint.
Always run list first if you are unsure whether a library has been indexed.
If nothing is indexed yet, use the docs-manage skill to scrape documentation
before searching.
Commands
list
List every indexed library and its available versions.

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-search is a skill published in the GitHub repository arabold/docs-mcp-server (1,701 stars, last pushed 4d ago), licensed MIT. It adds 54 tokens to every session and 1,035 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 2026-08-30.
