Tier: free_form_read.

{ "question": "When is my next flight?" }

Field	Rules
`question`	Required string, max 500 characters

Success

{ "answer": "Your next flight is …", "sources": 2 }

answer is short (roughly ≤ 600 chars) and redacted for codes / card-like numbers. sources is a count of underlying matches — not raw mail. If nothing answerable: {"error":"no_answer",…}.

Guidance for models

One question per call.
Prefer concrete questions over “summarize my inbox”.
Insufficient answer → narrower follow-up; do not jump to get_excerpt without clear user intent.
