generated tool `{}` requires adapter `{}` but got `{}`

Error message

generated tool `{}` requires adapter `{}` but got `{}`

What it means

GeneratedTool::new rejects the pair (definition, adapter) when the adapter's id does not equal definition.adapter_id. The adapter is what executes the generated tool, so a mismatch would mean the tool advertises behavior its executor cannot provide; the definition is rejected at registration rather than failing at call time.

Solutions

1. Register the tool with the adapter whose id matches definition.adapter_id.
2. Fix the adapter_id in the generated definition to name the adapter actually being used.
3. Check the capability/adapter resolution step that produced the pair.
