Reverse engineer anything with agents, from app behavior down to native binaries.

A harness is the system around a model that enables it to act as an agent: prompts, tools, memory, skills, orchestration, and more. Harnessing is the process of optimizing that system.

OpenCode is also available as a desktop application. ai/download.

Anthropic built Scion, a faster version control system for coding agents, and described it in Redesigning source control: a server-centric system built for hundreds of agents that read, write and land code at the same time.

OpenOPC: Build Your Personal AI-Native Company — Self-Built, Self-Run, Self-Grown

Control Unreal Editor directly from Claude Code via MCP. Hundreds of tools exposed via Unreal's ToolsetRegistry across 30+ toolsets: actors, blueprints, materials, Niagara, Control Rigs, Sequencer, State Trees, widgets, Gameplay Ability System, automation testing, and more.

Independent Auditing of AI Agents. Run by human or the agent itself, to answer the most crucial question in the AI Agent Economy. Is the agent doing what is supposed to do?

Agent skills that give coding agents taste: art direction, reference images and a browser check instead of generic AI pages

Let AI assistants and test suites use real phones like a human.

The unusual part: there is no model API bill. Harvey uses your Claude Pro or Max subscription through Claude Code, or your ChatGPT subscription through Codex. Model calls use the plan you already pay for, without an API key or per-token API billing.

Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.

Ears for coding agents: let AI hear, review and make sound. CPU-only, open source.

This is the home of the Pi agent harness project including our self extensible coding agent.
