This post is my submission for DEV Education Track: Build Multi-Agent Systems with ADK . What I Built GeoGuard AI – a multi-agent geological intelligence system that automates terrain risk assessment. The problem: geological hazard analysis (landslides, slope instability) usually requires multiple domain experts (geologists, climatologists) and manual synthesis. GeoGuard AI uses three specialized agents to replicate this collaborative workflow: a Hazard Agent , a Climate Agent , and an Orchestrator Agent . Given a location (e.g., Nanga Parbat – Higher Himalayan Syntaxis ), the system independently analyzes slope stability, climate trends, and then combines both to identify compounding risks – like how rising temperatures and rain-on-snow events can destabilize a "moderate" slope into a high-risk zone. The result is a fast, explainable, and modular AI system that demonstrates real-world agentic collaboration.…
