01Projects

What we maintain.

Agent harness · MIT

AgentSmith

Proof before done. An operating harness for AI coding agents.

Give your AI agent project rules, a definition of done, and a way to prove the work. AgentSmith installs a shared operating agreement and a work profile into a project. The agent runs the relevant checks, exercises the real path, records evidence, and leaves a handoff the next session can check.

Works with
Claude Code, Codex, Gemini and other coding agents
Profiles
Nine work profiles: software, DevOps, marketing, documents, data, admin, research, design and security
Install
Standalone app for macOS, Windows and Linux, or ask your agent to install it
