[alexander-alderman-webb]

The specific problem this fixes is text output that is JSON, as returned from

response = client.messages.create(
    model="claude-opus-5-5",
    max_tokens=16000,
    output_config={"format": {
        "type": "json_schema",
        "schema": {
            "type": "object",
            "properties": {"summary": {"type": "string"}},
            "required": ["summary"],
            "additionalProperties": False,
        },
    }},
    messages=[{"role": "user", "content": "Summarize Bill 119."}],
)

Closes AGT-3211
