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: 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)
