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:

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.
