Summary
Adds a changelog entry for version 1.0.50 that documents the fix for the Moonshot
400 tools.function.parameters is not a valid moonshot flavored json schemaerror.Root Cause
Moonshot (and some other third-party providers) only accept a strict subset of JSON Schema for tool parameter definitions. The CLI was sending schemas that included keywords like
additionalPropertieswhich Moonshot's schema validator rejects.Fix
Tool parameter JSON schemas are now sanitized before being sent to the model provider — unsupported keywords (e.g.
additionalProperties) are stripped so the definitions conform to each provider's expected schema flavour. This is consistent with the existing sanitization added in v1.0.22 for MCP tool schemas.
