Drug-leaflet search 10-100x faster — millisecond-level responses

Highlights

• ★We rebuilt the drug-leaflet search back-end on top of a pre-built index. Three tools now answer in single-digit milliseconds: opendata-search_drug_label (precise leaflet-field search), opendata-check_drug_interaction (scan 2–10 drug leaflets for interactions), and the leaflet-merge stage inside opendata-get_drug_details
• ★Warm-cache latency measured live: leaflet-field search 1.78 ms (down from 50–200 ms); two-drug interaction scan 0.27 ms
• ★The drug-licence registry search (opendata-search_drug and friends) still uses the previous path and will move in the next release — this ship focuses the highest-traffic surface first
• ★Zero user-facing changes: tool signatures, response schema, env vars are all unchanged — agents don't need to reconnect or change prompts
• ★Source: drug leaflets from twinkle-ai/tw-drug-labels-vision (CC-BY-4.0, 44,663 structured leaflets)

Example prompts

• Drugs whose leaflet mentions both warfarin and NSAIDs (noticeably faster)
• Find leaflets whose contraindications mention pregnancy
• Check interaction text across these 3 drug licence numbers
