Gemini rejects JSON Schema keywords like exclusiveMinimum, const, and anyOf that Pydantic V2 emits by default. Add a recursive sanitizer that converts these into the OpenAPI subset Gemini expects: - exclusiveMinimum -> minimum - exclusiveMaximum -> maximum - const -> enum (single element) - anyOf [T, null] -> flattened to T (Optional pattern) - strips $schema, additionalProperties, title, default, examples Fixes Intelligent-Internet#171

Problem
When using Gemini models, tool schemas generated by Pydantic V2 contain
JSON Schema keywords that Gemini rejects with
extra_forbiddenvalidationerrors:
The Gemini API expects a restricted OpenAPI-style subset of JSON Schema,
but
tool.input_schemais passed through without any sanitization.Fix
Added
_sanitize_schema_for_gemini()which recursively walks the schemaand converts incompatible keywords:
exclusiveMinimumminimumexclusiveMaximummaximumconstenum(single element)anyOf [T, null]T$schema,title,default,examplesApplied to
tool.input_schemain thegenerate()method beforebuilding the function declarations.
