When ToolInfo.Extra["strict"] is set to true, the adapter now passes strict: true on the ToolParam, enabling Anthropic's strict structured output mode which guarantees tool call inputs conform to the declared JSON Schema exactly. This prevents issues like array fields being returned as serialized strings, which can cause downstream JSON parsing failures. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

When the JSON Schema includes additionalProperties (e.g. false for strict mode), pass it through to the Anthropic API via ExtraFields. Required by providers like AWS Bedrock that enforce additionalProperties: false on all object types in strict mode. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
ToolInfo.Extra["strict"]is set totrue, the Claude adapter now passesstrict: trueon theToolParamChanges

Without
strict: true, Claude may return astringfor a field declared as"type": "array"in the tool schema. The string contains a serialized JSON array, but with improper escaping of nested quotes, making it unparseable. With strict mode enabled, the API guarantees schema conformance.
