What changed
Think now exposes the AI SDK's tool-call repair callback as
TurnConfig.repairToolCall. This lets applications correct unknown tools or malformed inputs before Think's tool hooks and execution.Think forwards the callback through
experimental_repairToolCall, the shared option name across supported AI SDK v6 and v7 versions, while presenting the stable name in its public API. Function-valued callbacks must be configured from a Think subclass rather than a sandboxed extension over RPC.Tests
Added a worker-level test that repairs fenced JSON, verifies the repaired input reaches both tool hooks, and confirms the tool executes exactly once. Updated Think's lifecycle docs and README.
Verified all 921 Think worker tests and typechecking against AI SDK v6 and v7, plus
pnpm run buildandpnpm run check.
