<!-- CURSOR_SUMMARY --> > [!NOTE] > **Medium Risk** > Tightens validation on tool metadata, which may break existing tools that relied on non-JSON-serializable `extras` values or keys; changes are localized and well-covered by tests. > > **Overview** > Adds **JSON-safety enforcement** for `ToolMetadata.extras`: top-level keys must be strings at model construction, and `validate_for_tool()` now recursively rejects non-JSON-native values (including non-finite floats) with path-rich `ToolDefinitionError` messages. > > Expands tests to cover valid/invalid nested `extras` cases and error-message quality, and bumps `arcade-core` version to `4.5.0`. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 2bab0db3c17f0ddb97868764d10494da543b39e5.
