The harness is the product

A cheap model on its own forgets, drifts, and quits early. Wrapped in Codewith's harness, it sets goals, keeps looping, spawns helpers and works while you're gone — and you only pay small-model prices for all of it.

Autonomous goals

Set a goal and a token budget with /goal. The agent drives itself toward it — pausing, resuming and reporting Goal achieved without babysitting.

Loops that don't quit

/loop every 10 minutes reruns a prompt on this thread forever. Point a cheap model at it and it grinds through the backlog while you sleep.

Schedules

One-time and timed runs with /schedule — /schedule tomorrow at 9am ships the report before standup.

Sub-agents & background agents

Fan work out to durable background agents with /agent — each on its own model. Run the loop on MiniMax while you stay on a flagship.

Many subscription logins

Keep ChatGPT, Claude.ai, Cursor and Grok profiles side by side. Hit a weekly limit? /profile to the next one — same thread, same context.

Switch model mid-session

Change model and provider in one command with /model. Draft cheap, finish sharp — without losing your thread.

Monitors

Watch builds, logs and commands with /monitor and react the moment something changes.

Sandboxed by default

Seatbelt on macOS, Landlock + bubblewrap on Linux, sandboxing on Windows. A cheap model going off-script still can't escape.
