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:
- Best minimal working snippet(s) (keep it copy/paste friendly)
- Notes on version / constraints / gotchas
- Sources (URLs if present in returned context)
Before presenting:
- Deduplicate similar results and keep only the best representative snippet per approach.
