Remove redundant runtime validation of the `mode` parameter in the WriteFile tool. The Pydantic `Literal["overwrite", "append"]` type annotation already ensures that only valid values can be passed. This change: - Simplifies the code by removing unnecessary validation - Maintains the same validation guarantees through Pydantic - Is validated by existing test suite, including `test_write_with_invalid_mode` which confirms Pydantic ValidationError is raised for invalid modes Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Summary
Remove redundant runtime validation of the
modeparameter in the WriteFile tool.Problem
The
WriteFiletool insrc/kimi_cli/tools/file/write.pycontained redundant validation code (lines 84-91) that checked whether themodeparameter was either "overwrite" or "append". This check is unnecessary because:Literal["overwrite", "append"]type annotation on theParams.modefield already enforces this constraint at the data validation layerValidationErrorbefore reaching the tool's__call__methodtest_write_with_invalid_modewhich confirms this behaviorSolution
Removed the redundant validation block, reducing code complexity while maintaining the same validation guarantees through Pydantic.
Test plan
test_write_file.py- 13/13 passed)test_write_with_invalid_modetest confirms Pydantic ValidationError is still raised for invalid modesChanges
