Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data. For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

No successful run was found on master ( 0cd72b5) during the generation of this report, so 1a3cd46 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report.

fix(core): preserve Field(description=...) in @tool decorator When using Annotated[type, Field(description='...')] syntax with the @tool decorator, the field descriptions were being lost during schema generation. This fix extends _get_annotation_description() to also check for FieldInfo objects and extract their description attribute. Fixes #34247
