exa-search

exa-search is a skill for Claude Code, Codex from magic3007/dotfiles. It costs 116 tokens per session (1,159 once invoked), scanned A, a copy of exa-search, MIT.

A web-search and webpage-extraction toolkit focused on scientific, technical, and research content. It can find relevant sources and retrieve content from specific URLs.

In plain words
What is it for?
Use it to research scientific or technical topics, find research papers, search academic domains, look up current information, and extract content from a supplied webpage or PDF.
Why use it?
It helps locate specialised information and pull material from technical pages without relying only on broad keyword searches.

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

exa-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 4d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/exa_extract.py, scripts/exa_search.py, tests/test_exa_search.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Origin

This is a copy

94% identical to exa-search — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Exa Web Toolkit

A skill for web-powered research tasks backed by Exa: web search and URL extraction. Exa's index combines high-quality keyword and semantic retrieval, which makes it well-suited to scientific, technical, and conceptual queries.

Routing — pick the right capability

Read the user's request and match it to one of the capabilities below. Read the corresponding reference file for detailed instructions before running commands.

User wants to... Capability Where
Look something up, research a topic, find current info Web Search references/web-search.md
Fetch content from a specific URL (webpage, article, PDF) Web Extract references/web-extract.md
Install or authenticate Setup Below

Decision guide

  • Default to Web Search for topic lookups, research questions, or "what is X?" queries. When the topic is scientific or technical, pass --category "research paper" to bias toward scholarly sources, and/or an academic --include-domains allowlist. See references/web-search.md for the two-pass academic strategy.
  • Use Web Extract when the user provides a URL or asks you to read/fetch a specific page. Prefer this over the built-in WebFetch for batch extraction (multiple URLs in one call) and for academic PDFs.

Academic source priority

For technical or scientific queries, prefer academic and scientific sources:

  • Peer-reviewed journal articles and conference proceedings over blog posts or news
  • Preprints (arXiv, bioRxiv, medRxiv) when peer-reviewed versions aren't available
  • Institutional and government sources (NIH, WHO, NASA, NIST) over commercial sites
  • Primary research over secondary summaries

Two levers to steer Exa toward scholarly content:

  1. --category "research paper" biases retrieval toward scholarly sources.
  2. --include-domains with a scholarly allowlist (arxiv.org, nature.com, pubmed.ncbi.nlm.nih.gov, etc.) restricts the domain pool.

Combine both for strictly academic results. See references/web-search.md for the full pattern.

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.
