Loop
Loop is the build → judge → fix app, at /loop.
What it does
Section titled “What it does”You give Loop a goal. A worker drafts a single-file HTML artifact, an adversarial judge scores it, and the loop keeps fixing the artifact until it passes — or until it hits the maximum number of iterations you set.
Key functions
Section titled “Key functions”- Worker and judge models — each defaults to Global (switcher) but can be set per-run to any model (Claude, Codex, local, and so on).
- Max iterations — cap how many build-judge-fix rounds run before Loop stops.
- Saved builds — browsable with live preview.
Setup and dependencies
Section titled “Setup and dependencies”Loop runs on the global model (Claude by default; switch it in the top bar). If the global model is a CLI, that CLI must be installed and logged in — for example the Claude Code CLI (claude), Grok Build CLI (grok), or others.
To run the judge locally, install Ollama and pull a model (for example ollama pull gemma2); Loop can then use a local judge with no API cost.
Where output goes
Section titled “Where output goes”Saved builds are kept and browsable with live preview inside the app. On disk they
live under ~/.erebros/loop-builds/.
- Set a sensible max-iteration cap so a run that cannot pass the judge stops cleanly.
- Mixing models — a strong worker with a strict, cheaper judge — is a good way to control cost.
