What it tells the agent
The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

# 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)
- "What's the latest on WebGPU?" — could be one news search (Extremely Simple) or a multi-angle survey of specs, browser support, community adoption, and benchmarks (Advanced)
Do NOT ask for confirmation when:
- The query is clearly extremely simple (fact lookups, single-entity questions)
- The query is clearly complex (explicit multi-constraint, "find everything", "exhaustive", "comprehensive")
- The user has already specified depth ("do a deep dive", "quick answer")
Note: if the user explicitly asks for something (e.g. "100" of something), continue to work until you've achieved it.
**What work needs to happen?** Identify which of these apply (most queries use 3-5):
1. **Seed from user input**: The user provided a list of entities to start from (company names, tickers, paper titles). Each seed becomes a parallel workstream.
2. **Define what qualifies**: What makes a result a valid "row"? Translate the user's criteria into concrete checks.
3. **Define what to capture**: What fields ("columns") does each result need? Build the schema before searching.
4. **Search broadly**: Generate diverse queries and run them to find candidates. This is where subagents do the heavy lifting.
5. **Extract structured data**: Pull specific fields from raw search results into the schema.
6. **Filter**: Apply hard constraints (dates, geography, thresholds) and soft judgments (quality, relevance, semantic checks).
7. **Merge and deduplicate**: Combine results from multiple subagents. Same URL = drop duplicate. Same entity from different sources = merge fields, keep best data.
8. **Score and rank**: For "best of" (e.g. "what's the best ___?") queries, define the scoring criteria explicitly, then rank.
9. **Synthesize narrative**: For research queries, organize findings by theme and write prose with citations.
## Step 2: Dispatch Subagents
### What subagents do
Subagents run Exa searches and process the results. They keep raw search output out of your context window. Each subagent should:
- Read the reference file(s) you point it to
- Run the specific searches you assign
- Return compact, structured output
### How to dispatch
Use the **Agent tool** to dispatch subagents. Reference file paths are relative to the directory this file was loaded from.
Use `model: "haiku"` for subagents.
Tell each subagent:
1. Which reference file(s) to read for instructions (always include the absolute path)
2. What specific searches to run or what specific work to do
3. What output format to return
**Template:**
```
Read the file at [this skill's directory]/references/searching.md for instructions on how to query Exa effectively.
Then do the following:
[specific task description]
[specific queries to run, if you are prescribing them]
[validation criteria -- what makes a result qualify, so the subagent filters before returning]
Return: [output format -- e.g. "compact JSON with name, url, snippet per result" or "markdown table with columns X, Y, Z"].
End with EXACTLY: `sources_reviewed: N` where N = sum of `numResults` across every `web_search_exa` call (incl. retries). E.g. calls with numResults 10, 10, 5 → `sources_revieweTrust audit

Questions
What does the search — exa-labs/exa-mcp-server skill do?
Exa MCP for web search and web crawling!
Is search — exa-labs/exa-mcp-server safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can search — exa-labs/exa-mcp-server access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
Which assistants does search — exa-labs/exa-mcp-server work with?
Its documentation mentions claude-code and cursor. That is what the text claims, not a compatibility test we ran.
How current is this page?
The grade is for one exact copy of the source (303e7fc3ab83), read on 2026-10-20. The repository is watched, and a new audit runs when it changes — this is the first audit.
