# Company Research

## Tool Restriction (Critical)

ONLY use `web_search_advanced_exa`. Do NOT use `web_search_exa` or any other Exa tools.

## Token Isolation (Critical)

Never run Exa searches in main context. Always spawn Task agents:
- Agent runs Exa search internally
- Agent processes results using LLM intelligence
- Agent returns only distilled output (compact JSON or brief markdown)
- Main context stays clean regardless of search volume

## Dynamic Tuning

No hardcoded numResults. Tune to user intent:
- User says "a few" → 10-20
- User says "comprehensive" → 50-100
- User specifies number → match it
- Ambiguous? Ask: "How many companies would you like?"

## Query Variation

Exa returns different results for different phrasings. For coverage:
- Generate 2-3 query variations
- Run in parallel
- Merge and deduplicate

## Categories

Use appropriate Exa `category` depending on what you need:
- `company` → homepages, rich metadata (headcount, location, funding, revenue)
- `news` → press coverage, announcements
- `people` → LinkedIn profiles (public data)
- No category (`type: "auto"`) → general web results, deep dives, broader context

Start with `category: "company"` for discovery, then use other categories or no category for deeper research.

### Category-Specific Filter Restrictions

When using `category: "company"`, these parameters cause 400 errors:
- `includeDomains` / `excludeDomains`
- `startPublishedDate` / `endPublishedDate`
- `startCrawlDate` / `endCrawlDate`

When searching without a category (or with `news`), domain and date filters work fine.

**Universal restriction:** `includeText` and `excludeText` only support **single-item arrays**. Multi-item arrays cause 400 errors across all categories.

## LinkedIn

Public LinkedIn via Exa: `category: "people"`, no other filters.
Auth-required LinkedIn → use Claude in Chrome browser fallback.

## Browser Fallback

Auto-fallback to Claude in Chrome when:
- Exa returns insufficient results
- Content is auth-gated
- Dynamic pages need JavaScript

## Examples

### Discovery: find companies in a space
```
web_search_advanced_exa {
  "query": "AI infrastructure startups San Francisco",
  "category": "company",
  "numResults": 20,
  "type": "auto"
}
```

### Deep dive: research a specific company
```
web_search_advanced_exa {
  "query": "Anthropic funding rounds valuation 2024",
  "type": "deep",
  "numResults": 10,
  "includeDomains": ["techcrunch.com", "crunchbase.com", "bloomberg.com"]
}
```

### News coverage
```
web_search_advanced_exa {
  "query": "Anthropic AI safety",
  "category": "news",
  "numResults": 15,
  "startPublishedDate": "2024-01-01"
}
```

### LinkedIn profiles
```
web_search_advanced_exa {
  "query": "VP Engineering AI infrastructure",
  "category": "people",
  "numResults": 20
}
```

## Output Format

Return:
1) Results (structured list; one company per row)
2) Sources (URLs; 1-line relevance each)
3) Notes (uncertainty/conflicts)


Step 3: Ask User to Restart Claude Code

You should ask the user to restart Claude Code to have the config changes take effect.

# Code Context (Exa)

## Tool Restriction (Critical)

ONLY use `web_search_exa`. Do NOT use other Exa tools.

## Token Isolation (Critical)

Never run Exa in main context. Always spawn Task agents:
- Agent calls `web_search_exa`
- Agent extracts the minimum viable snippet(s) + constraints
- Agent deduplicates near-identical results (mirrors, forks, repeated StackOverflow answers) before presenting
- Agent returns copyable snippets + brief explanation
- Main context stays clean regardless of search volume

## When to Use

Use this tool for ANY programming-related request:
- API usage and syntax
- SDK/library examples
- config and setup patterns
- framework "how to" questions
- debugging when you need authoritative snippets

## Query Writing Patterns (High Signal)

To reduce irrelevant results and cross-language noise:
- Always include the **programming language** in the query.
  - Example: use **"Go generics"** instead of just **"generics"**.
- When applicable, also include **framework + version** (e.g., "Next.js 14", "React 19", "Python 3.12").
- Include exact identifiers (function/class names, config keys, error messages) when you have them.

## Output Format (Recommended)

Return:
1) Best minimal working snippet(s) (keep it copy/paste friendly)
2) Notes on version / constraints / gotchas
3) Sources (URLs if present in returned context)

Before presenting:
- Deduplicate similar results and keep only the best representative snippet per approach.

## MCP Configuration

```json

  "servers": {
    "exa": {

# People Research

## Tool Restriction (Critical)

ONLY use `web_search_advanced_exa`. Do NOT use `web_search_exa` or any other Exa tools.

## Token Isolation (Critical)

Never run Exa searches in main context. Always spawn Task agents:
- Agent runs Exa search internally
- Agent processes results using LLM intelligence
- Agent returns only distilled output (compact JSON or brief markdown)
- Main context stays clean regardless of search volume

## Dynamic Tuning

No hardcoded numResults. Tune to user intent:
- User says "a few" → 10-20
- User says "comprehensive" → 50-100
- User specifies number → match it
- Ambiguous? Ask: "How many profiles would you like?"

## Query Variation

Exa returns different results for different phrasings. For coverage:
- Generate 2-3 query variations
- Run in parallel
- Merge and deduplicate

## Categories

Use appropriate Exa `category` depending on what you need:
- `people` → LinkedIn profiles, public bios (primary for discovery)
- `personal site` → personal blogs, portfolio sites, about pages
- `news` → press mentions, interviews, speaker bios
- No category (`type: "auto"`) → general web results, broader context

Start with `category: "people"` for profile discovery, then use other categories or no category for deeper research on specific individuals.

### Category-Specific Filter Restrictions

When using `category: "people"`, these parameters cause errors:
- `startPublishedDate` / `endPublishedDate`
- `startCrawlDate` / `endCrawlDate`
- `includeText` / `excludeText`
- `excludeDomains`
- `includeDomains` — **LinkedIn domains only** (e.g., "linkedin.com")

When searching without a category, all parameters are available (but `includeText`/`excludeText` still only support single-item arrays).

## LinkedIn

Public LinkedIn via Exa: `category: "people"`, no other filters.
Auth-required LinkedIn → use Claude in Chrome browser fallback.

## Browser Fallback

Auto-fallback to Claude in Chrome when:
- Exa returns insufficient results
- Content is auth-gated
- Dynamic pages need JavaScript

## Examples

### Discovery: find people by role
```
web_search_advanced_exa {
  "query": "VP Engineering AI infrastructure",
  "category": "people",
  "numResults": 20,
  "type": "auto"
}
```

### With query variations
```
web_search_advanced_exa {
  "query": "machine learning engineer San Francisco",
  "category": "people",
  "additionalQueries": ["ML engineer SF", "AI engineer Bay Area"],
  "numResults": 25,
  "type": "deep"
}
```

### Deep dive: research a specific person
```
web_search_advanced_exa {
  "query": "Dario Amodei Anthropic CEO background",
  "type": "auto",
  "numResults": 15
}
```

### News mentions
```
web_search_advanced_exa {
  "query": "Dario Amodei interview",
  "category": "news",
  "numResults": 10,
  "startPublishedDate": "2024-01-01"
}
```

## Output Format

Return:
1) Results (name, title, company, location if available)
2) Sources (Profile URLs)
3) Notes (profile completeness, verification status)
