The system performs on-device data cleansing to protect PII, uses event-driven reasoning for triage and logistics, and generates visual survival guides via Veo. It was created for the Google Cloud: All Things Agentic Hackathon.", "body_md": "*This article was created for the purposes of entering the Google Cloud: All Things Agentic Hackathon.*\n\nIn catastrophic natural disasters like flash floods, hurricanes, and earthquakes, cellular networks collapse and emergency dispatchers are overwhelmed with thousands of fragmented, panic-driven field messages. Volunteers trying to coordinate over open radio frequencies or mesh airwaves risk leaking sensitive Personally Identifiable Information (PII) such as phone numbers, names, and vulnerable home addresses.\n\nTo solve both bottlenecks, I built **Needflare** — an autonomous, privacy-first emergency intelligence and logistics agent running on Google Cloud.\n\nHere is how the system was built, how it operates asynchronously in the background, and how it unifies three cutting-edge Google AI models: **Gemini 3.7 Flash**, **Google Gemma 4**, and **Google Veo 3.1**.\n\nWatch the complete 3-minute technical demonstration in action:\n\nNeedflare operates across three decoupled, failure-tolerant tiers:\n\nIn disaster situations, zero data leakage is mandatory. When volunteers draft field reports, Needflare executes real-time data cleansing directly on the device:\n\n`gemma-4-26b-a4b-it`\n\nendpoint for high-precision category classification (`water`\n\n, `medical`\n\n, `shelter`\n\n, `rescue`\n\n, `food`\n\n, `power`\n\n) and urgency scoring.`[SECTOR_ALPHA_SNAP]`\n\n), storing reports in an encrypted local buffer.When intermittent connectivity (LoRa mesh, satellite, or restored 4G) reconnects, the volunteer triggers a burst sync:\n\n`needflare-reports`\n\n).`needflare-db`\n\n) across three synchronized collections: `reports`\n\n, `tasks`\n\n, and `veo_guides`\n\n.Traditional emergency dispatchers spend crucial hours calculating supply quotas. Needflare eliminates this bottleneck using **Gemini 3.7 Flash** orchestrated through **Google GenKit v1.41**:\n\nInstead of an open-ended conversational chat loop, the agent executes an event-driven reasoning flow (`needflareTriageFlow`\n\n) with strict tool execution:\n\n`triageSectorTool`\n\n: Dynamically elevates or de-escalates sector threat levels.`createLogisticsTaskTool`\n\n: Auto-dispatches supply convoy tasks to Firestore, calculating required payloads based on humanitarian Sphere standards (e.g. 15L of potable water per person per day).`triggerVeoVisualGuideTool`\n\n: Triggers visual survival video synthesis when acute survival challenges are detected.Under extreme trauma or panic, victims often cannot parse dense text instructions.\n\nNeedflare integrates **Google Veo 3.1 Fast** (`veo-3.1-fast-generate-preview`\n\n) to generate zero-text, high-contrast 8-second instructional video broadcasts (such as floodwater purification using charcoal and fabric, or emergency thermal shelter construction). The server polls the long-running generation operation, downloads the verified MP4, and registers the protocol in Firestore for immediate playback across tactical coordinator dashboards.\n\nBuilding Needflare demonstrated the immense power of pairing Google's agentic ecosystem — **GenKit**, **Gemini 3.7 Flash**, **Gemma 4**, and **Google Veo** — with serverless Google Cloud infrastructure.
