Run on-device first. + 2. Infer expected intents from user text (weather, alarm, timer, message, reminder, contacts, play music). + 3. Validate local output against tool schema (required args + type checks). + 4. Validate semantic consistency against extracted slots (time, minutes, location, recipient/message, reminder title/time, contact query, song). + 5. Apply dynamic confidence thresholds by complexity: + - single-intent: 0.80 + - two intents: 0.92 + - three+ intents: 0.96 + 6. Fallback to cloud only if local output fails semantic/schema checks or confidence threshold. + + Why this should improve your benchmark: + + - It explicitly catches the failure mode you showed: high-confidence but wrong local calls (especially timer/reminder/multi-call hard tasks). + - It preserves local speed/ratio when local calls are actually coherent. + + Validation status: + + - Syntax check passed: python -m py_compile main.py. + - Full benchmark could not be completed in this environment due blocked network access for Gemini fallback (httpx.ConnectError), so I couldn’t produce a + new score locally. + + Next step to verify on your side: + + 1.
