# Looper

> Looper keeps each recurring AI agent job in one Markdown spec, scores every run, and shows all loops and their latest scores on one screen. Rex St. John is building it to run his own loops. It is in development: there is no sign-up, no pricing and no public release.

## Pages

- [Looper home](https://looper.rexstjohn.com/): what Looper does, the bank view (example data), the parts of a loop spec, what happens on each run (run, eval, learn, rewrite the spec), who it is for, and its status.
- [Loop spec format](https://looper.rexstjohn.com/spec/): draft 0.1 of the loop file format. Front matter fields, the nine sections (Objective, Evals, Sources and instructions, Quality control, Macros and recursion, Learning, Schedule, Roadmap, OKRs), rules for self-rewrites, and a full example.

## Facts

- Author: Rex St. John (https://www.rexstjohn.com/)
- Status: in development, built for the author's own use
- The bank table on the home page uses example data, not real runs.
- Rex writes the specs and decides what ships. AI agents write much of the code and the first drafts, and he reviews them.
