Searches the web through Exa 3.0 with six Python scripts—lite/auto/deep search with category, domain, and date filters, Dynamic Highlights, structured output with field-level citations, clean extraction from known URLs, cited answers, and the async Agent API for list building, enrichment, and multi-hop research. This skill should be used for any web search, fact lookup, current events, finding papers, companies, people, or news, reading known URLs, questions that need cited answers, building lists of entities that match criteria, or enriching records with web data. It is the default web search tool (built-in WebSearch is blocked). Triggers on search the web, look up, find pages, research with citations, Exa, list of companies, enrich.

Six scripts over Exa 3.0 (API spec 2.0.0, synced 2026-10-19). S=~/.claude/skills/exa-search/scripts.
Prerequisite: EXA_API_KEY (https://dashboard.exa.ai).
| Task | Command |
|---|---|
| Quick lookup, cheapest | python3 $S/exa_search.py "query" --lite --highlights --no-text |
| General web search | python3 $S/exa_search.py "query" --highlights --no-text |
| Papers / companies / people / news | ... exa_search.py "query" --category publication (or company, people, news) |
| Read known URLs | python3 $S/exa_contents.py URL1 URL2 --highlights --no-text |
| Cited answer | python3 $S/exa_research.py "question" --sources |
| Cited answer from specific sites/dates | ... exa_research.py "question" --domains a.org --after 2026-01-01 (routes to /search) |
| One synthesized answer or JSON from a search | ... exa_search.py "question" --text-output "Short answer" / --schema-preset company |
| Multi-step research, lists, enrichment | python3 $S/exa_agent.py run "task" --effort medium (see references/agent-api.md) |
| Pages like a URL | python3 $S/exa_similar.py URL (deprecated endpoint; prefer a descriptive exa_search.py query) |
Search cheaply → pick URLs → extract selectively → reason.
python3 $S/exa_search.py "query" --lite --highlights --no-text -n 10 # ranked excerpts, no full text
python3 $S/exa_contents.py URL1 URL2 --highlights-query "what I need" --no-text
python3 $S/exa_contents.py URL1 --max-chars 5000 # full text only when needed
exa_search.py; --no-text saves context, not dollars (lite and auto bundle contents for 10 results).--dynamic (Dynamic Highlights) shares one budget across all results—use it when the results feed one context.--domains, --exclude-domains, --category, --after/--before.... --json | python3 ~/.claude/skills/firecrawl/scripts/filter_web_results.py --fields "title,url,highlights" --max-chars 3000.| Flag | Latency | $/1k requests | Notes |
|---|---|---|---|
--lite | ~450ms | $4 | Cache only. Accepts query, --objective, category, -n, domains, dates, text, highlights, --snapshot-as-of, --location, --safe—nothing else |
(default auto) | ~1s | $7 | Best balance; full parameter set |
--deep-lite | ~4s | $12 | Lightweight synthesis; --additional-queries |
--deep | 4–15s | $12 | Multi-step search and synthesis |
legacy --fast / --instant / --deep-reasoning / --neural | — | $7 / $4 / $15 / — | Still accepted with a stderr hint |
Extras: results above 10 add $1/1k; --summary adds $1/1k pages; exa_contents.py is $1/1k pages per content type; exa_research.py is $5/1k. Agent runs: medium $0.10 (script default), auto metered ≤$5, ultra metered ≤$20; full effort table in references/agent-api.md.
--text-output "desc", --output-schema JSON, --schema-file F, or --schema-preset (company, paper-survey, competitor-analysis, person, news-digest) work on every type except lite, within 10 properties in total (nested and array-item properties count) and 2 levels; every array needs items. The answer arrives in output.content; output.grounding gives per-field citations with [H]/[M]/[L] confidence. Add --system-prompt for format or tone.
/answer has no source filters. exa_research.py sends --domains, --exclude-domains, --after, --before, and -n to /search (auto + text schema, $7/1k) and says so on stderr. Without them it uses /answer, where --model exa|exa-pro|exa-fast|exa-research and --stream apply.--lite.-n results is normal; rerun without --lite when coverage matters./search object schemas cap at 10 properties in total and 2 nesting levels. Larger shapes go to exa_agent.py. Never add citation or confidence fields—grounding has them.--dynamic sends the Exa-Beta: dynamic-highlights-2026-08-28 header and cannot combine with --highlights-max-chars.--category company/people reject --after/--before; people also rejects --exclude-domains. --category publication rejects --domains (400 UNSUPPORTED_PUBLICATION_INCLUDE_FILTER, probed 2026-10-19 on arxiv.org, openreview.net, nature.com, jstor.org): pin venues with --domains and no category; --exclude-domains works with it.research paper is now publication (auto-mapped); pdf/github were deprecated in Exa's 2026-07-23 changelog and now pass as soft hints; tweet is rejected.--domains a.com --domains b.com and --domains a.com,b.com both send both domains.--max-age-hours 0 always fetches fresh, -1 is cache only. --livecrawl still works but is mapped (always→0, preferred→1, never→-1). --snapshot-as-of DATE returns historical versions: pay-as-you-go gets a 100-request trial, a rolling 5-month window, and 10 results or 1 contents URL per request; Free gets 403. It excludes freshness flags, --subpages, --category, and --deep.--must-include/--must-exclude (approximate word matching), --context, and --subpages on search (use exa_contents.py --subpages).exa_research_async.py (Research API returns 410, probed 2026-10-19) prints the exa_agent.py equivalent and exits 2.--effort (default medium) and polls to completion. Pair --effort auto/ultra with --max-cost (otherwise the cap is $5/$20); fixed efforts reject it. If polling is lost, the run continues and the script prints status RUN_ID --wait (exit 3).exa_research.py got no answer. exa_contents.py exits 1 when every URL failed.| Need | Tool |

This skill should be used when creating, auditing, or maintaining AGENTS.md files and Codex CLI configuration for any project—including initializing AGENTS.md for cross-agent compatibility (Codex, Cursor, Copilot, Devin, Jules, Amp, Gemini CLI), generating config.toml or .rules files, scaffolding .agents/skills/, converting CLAUDE.md to AGENTS.md, or auditing existing agent configs for bloat and staleness. Complementary to codex-orchestrator (which executes subagents; this skill creates the config files they consume).
