exa-search

exa-search is a skill for Claude Code from wanshuiyin/Auto-claude-code-research-in-sleep. It costs 49 tokens per session (2,387 once invoked), scanned A, original, MIT.

A web search tool that finds pages across the internet and extracts useful content from the results. Exa is the search service it uses.

In plain words
What is it for?
Use it to find and read blog posts, documentation, news, company pages, and research papers on a topic.
Why use it?
It helps when academic databases are too narrow or when search results alone are not enough to understand a page.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: positional $N argument.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is echo " Fix: rerun bash tools/install_aris.sh or smart_update.sh (refreshes ~/.aris/repo), export ARIS_REPO, or copy the helper to tools/." >&2.

Good fit Use it to find and read blog posts, documentation, news, company pages, and research papers on a topic.

About the project

ARIS is a collection of Markdown-based skills that define a workflow for autonomous machine-learning research, including idea discovery, experiment automation, and review loops. Researchers and AI coding agents use it across tools such as Claude Code, Codex, Cursor, and OpenClaw without depending on a single framework. The catalogue entries are ARIS workflow skills and agents.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 12d 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.

Search query: $ARGUMENTS

Role & Positioning

Exa is the broad web search source with built-in content extraction:

Skill Best for
/arxiv Direct preprint search and PDF download
/semantic-scholar Published venue papers (IEEE, ACM, Springer), citation counts
/deepxiv Layered reading: search, brief, section map, section reads
/exa-search Broad web search: blogs, docs, news, companies, research papers — with content extraction

Use Exa when you need results beyond academic databases, or when you want content (highlights, full text, summaries) extracted alongside search results.

Constants

  • EXA_FETCHER — canonical name exa_search.py, resolved per shared-references/integration-contract.md §2 (Policy D1 — standalone /exa-search has no documented fallback, so unresolved helper terminates with an explicit error).
  • MAX_RESULTS = 10 — Default number of results to return.

Overrides (append to arguments):

  • /exa-search "RAG pipelines" — max: 5 — top 5 results
  • /exa-search "diffusion models" — category: research paper — research papers only
  • /exa-search "startup funding" — category: news, start date: 2025-01-01 — recent news
  • /exa-search "transformer" — content: text, max chars: 8000 — full text mode
  • /exa-search "transformer" — content: summary — LLM-generated summaries
  • /exa-search "transformer" — domains: arxiv.org,huggingface.co — domain filter
  • /exa-search "https://arxiv.org/abs/2301.07041" — similar — find similar pages

Setup

Exa requires the exa-py SDK and an API key:

pip install exa-py

Set your API key:

export EXA_API_KEY=your-key-here

Get a key from exa.ai.

Workflow

Step 1: Parse Arguments

Parse $ARGUMENTS for:

  • query: The search query (required) or a URL (for find-similar mode)
  • similar: If present, use find-similar mode instead of search
  • max: Override MAX_RESULTS
  • category: research paper, news, company, personal site, financial report, people
  • content: highlights (default), text, summary, none
  • max chars: Max characters for content extraction
  • type: Search type — auto (default), neural, fast, instant
  • domains: Comma-separated include domains
  • exclude domains: Comma-separated exclude domains
  • include text: Phrase that must appear in results
  • exclude text: Phrase to exclude from results
  • start date: ISO 8601 date — only results after this
  • end date: ISO 8601 date — only results before this
  • location: Two-letter ISO country code

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.

exa-search is a skill published in the GitHub repository wanshuiyin/Auto-claude-code-research-in-sleep (16,030 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 2,387 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.
