Why it matters now: Universal, model-agnostic operating harness for AI agents
AgentSmith is a universal operating harness for AI agents, designed to be portable and battle-tested. It provides a lean core and work-type profiles that can be assembled by a single setup script. The harness is adaptable to various types of work, including software development, devops/setup, marketing, document creation, data crunching, research, design, and general admin. The project grew over six months of real, autonomous work and is now in its fifth iteration, scrubbed of project specifics and split into a universal core and swappable work-type profiles. The harness works in four steps: install once, work one unit at a time, verify before done, and hand off early and improve the harness.
Install once using the setup.sh script, which assembles a deliberately lean CLAUDE.md from the universal core and the profile(s) for the kind of work you're doing.
