# exa-search

This skill turns broad research requests into planned Exa searches, filtering, and synthesis. Use it for competitor analysis, literature reviews, or lead research.

## What it does

exa-search acts as a research orchestrator. It interprets the request, judges its complexity, plans the search, and sends larger tasks to subagents. The final pass merges findings, removes duplicate sources, applies filters, and turns the results into a cited narrative. Small lookups can stay in the main agent.

The skill reaches Exa through the MCP server `https://mcp.exa.ai/mcp`. OAuth through `auth.exa.ai` is the recommended route; an API key can also be supplied with `Authorization: Bearer …`, `?exaApiKey=…`, or `EXA_API_KEY`. Anonymous access works with rate limits. Time-based requests are converted to explicit dates first, while ambiguous research depth can trigger a request for confirmation.

Anonymous access is rate-limited, so recurring deep research needs OAuth or an API key. The skill also relies on the Exa connection rather than falling back to generic web search after an authentication or rate-limit error.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill exa-search -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/exa-search/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/exa-search/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill exa-search -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/exa-search/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill exa-search -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/exa-search/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cline/skills exa-search
```

2. **Manually: put the files in place**
- File: `.github/skills/exa-search/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill exa-search -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cline/skills --path skills/exa-search
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/exa-search/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cline/skills --skill exa-search -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/cline/skills/tree/HEAD/skills/exa-search/SKILL.md

## When to use it
- break down a complex research request
- cross-check findings from multiple sources
- filter candidates against explicit criteria
- produce a cited research brief
- find leads or competing products

## Example prompts
- Research browser testing tools and prepare a sourced comparison.
- Find everything about current WebGPU browser support, then group the findings by topic.
- Run a deep competitor review for this product and merge duplicate sources.

# Exa Research Orchestrator

You are the orchestrator. Your job: understand the query, plan the work, dispatch subagents with the right context, then compile and deliver the final result.

## Prerequisites: Auth

Server: `https://mcp.exa.ai/mcp`.

1. **OAuth (recommended)** — client opens `auth.exa.ai`, user signs in with Google / SSO / email, JWT is attached automatically. No key to copy.
2. **API key** — if OAuth isn't available, get one at https://dashboard.exa.ai/api-keys and pass it via `Authorization: Bearer …`, `?exaApiKey=…`, or `EXA_API_KEY` (local npm).
3. **Anonymous** — works without setup but rate-limited.

On auth / rate-limit errors, surface the fix (prefer OAuth) — don't fall back to generic web search.

## Date Calculation (Do This First)

If the query involves time ("last week", "recent", "past 6 months"), calculate exact dates from today's date in your environment context. Write out the calculation explicitly before doing anything else. Never eyeball dates or reuse dates from examples.

## Step 1: Assess the Query

Read the user's query and determine two things:

**How complex is this?**
- **Extremely Simple** (e.g. reading the contents of 1-2 pages): Handle it yourself. Read `references/searching.md` for query-writing guidance, run the searches, review and filter results, then respond directly. No subagents needed.
- **Moderate** (when a fast or low-effort search is requested): Delegate to 1 subagent to keep your context window clean.
- **Advanced** (clear topic, clear filters, a few parallel searches): Light subagent use. One round of parallel subagents, then compile.
- **Complex** (cross-referencing across entity types, multi-hop chains, exhaustive coverage, semantic filtering): Full multi-pass with parallel subagents.

**Confirm when ambiguous:**
If the query could reasonably be handled as Extremely Simple/Moderate OR as Advanced/Complex, pause and ask the user before proceeding. Present:
1. Your interpretation of the query
2. The two (or more) plausible complexity levels
3. What each level would look like in practice (e.g., "I can do a quick 1-2 search lookup, or I can fan out across 3-4 subagents to get deeper coverage")
4. Let the user choose

Examples of ambiguous queries:
- "What are the best LLM fine-tuning frameworks?" — could be a quick opinionated list (Moderate) or an exhaustive evaluated comparison (Complex)
- "Find competitors to Acme Corp" — could be a quick search for known competitors (Moderate) or a deep sweep across funding databases, press, and niche directories (Complex)
```
