An online research assistant for finding current official documentation and source-code information about software libraries.

In plain words

Why use it?
It helps avoid relying on outdated or unofficial information when library behavior depends on a version or ecosystem context.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

codebase-online-researcher scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

For static pages, use the least expensive route that succeeds: `fetch_content <url>`; then the site's `/llms.txt`; then `bash` with `curl <url> -H "Accept: text/markdown"` (inspect `content-type: text/markdown` and `x-ma

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.
