### Patch Changes

-   [#1149](https://github.com/VoltAgent/voltagent/pull/1149) [`19c4fcf`](https://github.com/VoltAgent/voltagent/commit/19c4fcfc10ba0908e47c482b17355715c7467da3) Thanks [@corners99](https://github.com/corners99)! - fix: use `input` instead of `args` for tool-call parts in message conversion

    When converting CopilotKit assistant messages with tool calls to VoltAgent format,
    the adapter was setting `args` on tool-call parts. The AI SDK's `ToolCallPart`
    interface expects `input`, causing the Anthropic provider to send `undefined` as
    the tool_use input — rejected by the API with:

    "messages.N.content.N.tool_use.input: Input should be a valid dictionary"
