The lightest harness
for agentic work.

An open-source coding agent for your terminal. A short prompt, four tools, and the model does the thinking. The whole harness weighs ~1k tokens, so the model works at the full extent of its own ability.

~1k tokens of harness

The whole system prompt and tool set, measured. No rails, no decision tree. The model plans; the harness does not.

Small tool surface

Plain contracts — read, bash, edit, write — described once. The model decides how to use them.

72–78% cheaper

Same task, same eval, fewer tool calls than Claude Code on every model tested. Fewer steps, less error along the way. Every trace is public.

Free and low-cost models

Long tasks take many steps. A catalog of free and stealth models so they stay affordable.

Bring your own keys

Anthropic, OpenAI, DeepSeek, Kimi, OpenRouter — or any compatible endpoint.

Terminal native

The environment is your machine, not a prompt flow. A TUI for long sessions, resumable context, /help for everything.
