Agent Harness Builder is a visual tool for orchestrating multi-agent AI workflows. It solves the "this" problem: when people say "build this," frontier models handle the build, but defining and structuring the "this" is where things break down. Long-running tasks lose context. AI drifts.

Inspired by Anthropic's research on long-running task harnesses, the goal is to bring structured AI orchestration to anyone with expertise, not just devs.

You create projects with structured tasks and step-by-step checklists that keep agents anchored. Three AI abstractions layers: Skill Generation captures domain expertise, Process Team designs collaboration workflows, and Task Initialization breaks down projects. Then multi-agent orchestration executes it all with real-time tracking, cost monitoring, and AI-generated summaries

Works across domains. You bring your expertise. The harness structures it. AI handles the build.
