Design Agent Loops That Hold Their Shape
Turn a goal into a repeatable cycle with explicit checks and a defined ending. Convert between prompts and loops, start from a template, and let the quality analyzer point out what is missing.
Windows and macOS apps are coming soon.
Five steps to a reusable loop
1. State the objective
Write the outcome so it can be judged. The analyzer flags objectives that cannot be checked.
2. Lay out the execution steps
Order the work the loop performs on every pass, from gathering context to producing a draft.
3. Add validation and guardrails
Define what good looks like and what the process is not allowed to do.
4. Decide retry and error behaviour
Choose what happens on a failed check and how many attempts are reasonable.
5. Fix the final report format
Decide the deliverable shape up front so every run produces comparable output.

Loop builder FAQ
It is a tool for designing the repeatable cycle an AI process follows: the objective, the steps, the validation checks, the retry rules and the point at which the work is complete.
