--tool defaults to claude if you omit it. Swap for grok, codex, or opencode. Week one is report-only.

You design a system that discovers work, hands it to agents, verifies results, and persists state — instead of typing the next prompt yourself.

What do you want to do?

This is a pattern library for operating agents around a codebase. It is not a “rewrite the module” button.

Full jobs table: docs/jobs.md.

Patterns

Interactive picker: showcase. Index: patterns/registry.yaml.

Getting started

Empty repo → first STATE.md walkthrough: scripts/empty-to-state-demo.sh.

Roll out L1 report → L2 assisted → L3 unattended only after the verifier has been right for a week. See loop-design-checklist.

Loop Ready now weights recent runs harder than files on disk. A 30-day-old STATE.md is not L3.

Examples by tool
