Mill Floor Sim

Live

Run a labeled mill sim, fix a demo project and drive an arm in stretches.

Not published

It passed its checks, but publishing was off where it was built, such as a local run, so it has no live link. Its recorded demo is in the panel.

The muse

A long model loop on a clearly labeled simulation that fixes a bundled practice project and drives a sim arm with roles, an approval gate and a ledger.

Models

Muse WonderPlans each stretch: demo project fixes and staged sim arm moves from the picked role and goal.

Cost per run: $1.85 est.
Runs so far: 8 calls · 6.8k tokens · $0.001
Build cost: $0.03 est.

Limits

This is a clearly labeled simulation. There is no real mill, real robot arm, or real factory system.
The bundled project is made up for practice. It cannot fix real code or equipment.
Work runs in stretches while the page stays open. There are no background or scheduled runs.
Arm moves only change the on screen simulation. Staged commands need human approval to advance.
Ledger entries are stored in the browser and are practice records only.

Muse app connector

Add it in the Muse app as a custom connector. It exposes 3 actions: start_stretch, approve_stage, read_ledger.

Recorded demo

How it was built

Muse Code made 63 tool calls and 22 edits across 22 files (+1538 −32).
npm run verify passed on the first try.
Screenshot judge: pass. Final screen shows stretch summary with project fix status and sim arm position in plain words plus diagram at Bin B.
Built in 6 min for about $0.03 in model calls (est.).
Publishing is off for this run (it's a Vercel preview, and a product published here would deploy into production's Vercel projects), so the product didn't get its own link. The preview, checks and demo above ran for real.
