The little agent crew that could

Big ideas.
Tiny budget.

A little task. A few moving parts. Watch cheapoS work, test, and get a second opinion—then peek under the hood.

Watch a walkthrough

A recorded rehearsal. Scripted agents used the real cheapoS engine to edit files and run tests. Playback happens in your browser.

Coming later

Try a live task

Let real AI agents tackle a preset mission. Live model responses, real verification, and a result of your own.

Recorded, not live. No jobs, tests, or model requests run when you watch. Review decisions are scripted. These examples demonstrate the workflow; they do not measure live AI performance or count toward the leaderboard.

01 / Pick a little mission

Something small.
Something useful.

Three ways to meet the crew.

The brief

A bug. A fix. A second opinion.

Fix clamp so it respects both bounds and rejects an inverted range. Keep the change small and add a regression test.

What done looks like

  • Values stay within the lower and upper bounds.
  • An inverted range raises ValueError.
  • The regression tests pass before approval.
Pause, skip ahead, or inspect every detail.

Generated from the unmodified cheapoS engine at 89c39ff253f80b4b0d832b930d3460800a357af7 on 2026-09-19. Worker responses and reviewer decisions were predefined. The engine performed real edits, verification commands, and checkpoints in disposable task copies. No visitor workspaces or accounts are involved.
