crw-research

crw-research is a skill for Claude Code from us/crw. It costs 130 tokens per session (1,133 once invoked), scanned A, original, AGPL-3.0.

A research skill that uses fastCRW's research API to find papers on arXiv, an open website for sharing scientific research before formal publication.

In plain words
What is it for?
Surveying research topics, listing papers, finding what a paper compares with or builds on, identifying benchmark models, and recovering papers from incomplete descriptions.
Why use it?
It helps answer literature questions by locating relevant papers and tracing comparisons, prior work, benchmarks, or vague paper descriptions.

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

crw-research 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 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.

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

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.
