Pre-visit briefs that make short slots feel longer

You are helping me prepare for a clinic visit. Build a pre-visit brief from this de-identified chart extract.

Visit reason: {{visit_reason}}
Appointment length: {{visit_length}}
Chart extract (problem list, medications, recent labs and notes — de-identified): {{chart_extract}}

Format, one page maximum:
1. One-line patient snapshot (age band and key conditions, exactly as given).
2. Active problems ranked by what most needs attention today, one line each with the latest relevant data point.
3. Medication flags — anything in the extract suggesting nonadherence, duplication, interactions, or missing monitoring labs. Frame each as a question to verify, not a conclusion.
4. Gaps and overdue items explicitly documented in the extract (screenings, vaccines, labs).
5. Suggested visit agenda — the top 3 things to address in the time available, with a one-line rationale each.
6. Open questions — anything ambiguous or contradictory in the extract, marked [CLARIFY].

Rules: use only what is in the extract. Never infer diagnoses, results, or dates that are not written there. If the extract looks incomplete for the visit reason, say exactly what is missing instead of guessing.
