About agentsmith

AgentSmith — the universal agent harness Vibe coding gets you a working demo. AI-assisted engineering is what keeps it standing once customers arrive, the product changes, or another engineer has to touch it. Agentsmith is that second layer — a portable, battle-tested operating system for Claude Code (and any agent that reads a / / ). Drop it on any machine, pick the kind of work you're doing, and the same disciplined core adapts to it — software, devops/setup, marketing & outreach, document creation, data crunching, research, design, and general admin. The agent is the model plus the harness. The model is 10% of the outcome; the harness — the rules, tools, memory, guardrails, and feedback loops around it — is the other 90%, and it's the part you control. This repo is that 90%, generalized and reusable. (The reasoning is in ; the public work these ideas build on is credited in full under principles & influences.) It didn't come from a whiteboard. It grew over 6 months of real, autonomous work — data crunching, marketing outreach, dozens of smaller projects, and one software product still in active development after half a year — across hundreds of sessions.
