AI SDK v5 Compatibility for @goat-sdk/adapter-vercel-ai

🚀 Feature Request: AI SDK v5 Compatibility for @goat-sdk/adapter-vercel-ai

Problem

Cannot use GOAT SDK with AI SDK v5 due to compatibility issues:

• @goat-sdk/adapter-vercel-ai@0.2.10 requires ai: ^4.0.3
• AI SDK v5 (ai: ^5.0.0) introduces stricter schema validation
• Runtime errors occur when using wallet tools:

Error: Invalid schema for function 'sign_message': schema must be a JSON Schema of 'type: "object"', got 'type: "None"'.

Affected tools:
get_address, get_chain, get_balance, sign_message, get_token_info_by_ticker, etc.

---

✅ Solution

Update @goat-sdk/adapter-vercel-ai for AI SDK v5 compatibility:

1. Update peer dependency to ai: ^5.0.0
2. Fix schema generation — use type: "object" instead of type: "None"
3. Ensure backward compatibility with v4

🧩 Context

Environment:
AI SDK v5.0.76, pnpm workspace

Impact:
Blocks projects migrating to AI SDK v5
