---name: reference-sdkdescription: Check reference SDK implementations using btca askuser-invocable: false---

Reference SDK Check

When implementing SDK features or debugging provider-specific issues, check reference implementations.

When to Use

• Implementing SDK features
• Debugging provider-specific issues
• Understanding how other libraries solve similar problems
• "How does Vercel AI SDK do X?"
• "Check Anthropic SDK for Y"

Commands

Use btca ask to check how reference SDKs implement similar features:

# Check Vercel AI SDK for streaming patterns
btca ask -r vercel-ai -q "How does streamObject work?"

# Check Anthropic SDK for tool calling
btca ask -r anthropic-sdk -q "How are tools defined and called?"

# Check Zod for validation patterns
btca ask -r zod -q "How does safeParse handle errors?"

Configured Resources

• vercel-ai - Streaming, tool calling, structured output
• anthropic-sdk - Anthropic API patterns
• zod - Schema validation

Add more: btca config resources add -n <name> -t git -u <url> -b <branch>

When to Check

1. Before implementing - See how others solved similar problems
2. When debugging - Find how reference code handles edge cases
3. Multi-provider support - Compare implementations across SDKs
4. Validation patterns - Check idiomatic approaches

Don't Use For

• Documentation lookups (use /nia-docs instead)
• Simple API questions (use WebSearch)
• Project-specific patterns (use Grep/Glob)
