Company Research

Copy the content below and paste it into Claude Code. It will set up the MCP connection and skill for you. ```` Step 1: Install or update Exa MCP If Exa MCP already exists in your MCP configuration, either uninstall it first and install the new one, or update your existing MCP config with this endpoint. Run this command in your terminal: claude mcp add --transport http exa "https://mcp.exa.ai/mcp?tools=web_search_advanced_exa" Step 2: Add this Claude skill --- name: company-research description: Company research using Exa search. Finds company info, competitors, news, financials, LinkedIn profiles, builds company lists. Use when researching companies, doing competitor analysis, market research, or building company lists. context: fork --- # 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 Search

Finds real snippets and docs from GitHub, StackOverflow, and technical docs. Use when searching for code examples, API syntax, library documentation, or debugging help. context: fork --- # Code Context (Exa) ## Tool Restriction (Critical) ONLY use `get_code_context_exa`. Do NOT use other Exa tools. ## Token Isolation (Critical) Never run Exa in main context. Always spawn Task agents: - Agent calls `get_code_context_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 ## Inputs (Supported) `get_code_context_exa` supports: - `query` (string, required) - `tokensNum` (number, optional; default ~5000; typical range 1000–50000) ## 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. ## Dynamic Tuning Token strategy: - Focused snippet needed → tokensNum 1000–3000 - Most tasks → tokensNum 5000 - Complex integration → tokensNum 10000–20000 - Only go larger when necessary (avoid dumping large context) ## 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": { "type": "http", "url": "https://mcp.exa.ai/mcp?tools=get_code_context_exa" } } } ``` Step 3: Ask User to Restart Claude Code You should ask the user to restart Claude Code to have the config changes take effect. ````

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.
