# Amplio: A Lightweight Agent Harness for Robust and Long-Horizon Runs * Lightweight: Multi-agent framework based on a simple step model that provides natural crash-resume capability, and agent / user / env message coordination. Agents work through a small set of generic tools: shell, file edit, sub-agent spawn, and inter-agent coordination. * Robust: DB-first persistence; crashing at any point during the agentic loop can be robustly resumed. * The agentic loop is guaranteed to be consistent, failures in the tool / environment are not handled by the harness, but reported to the agent. * Sub-agent session trees are automatically resumed upon server recovery. * Autonomous: Each run can be fully driven by the autonomous agent, or cooperatively driven with user interactions. ## Installation Amplio is a single binary with an embedded frontend. To build it yourself you need Go (see `go.mod` for the version) and Node.js 22+: make build The first build also downloads a 130 MB embedding model (cached) to build the local recall table; `make build LOCAL_EMBED=0` skips it, and recall then ranks by keyword match alone. ## Quick start
