Suits developers already using Codex, Cursor or Claude Code who want repeatable agent workflows; you need Node.js and basic familiarity with prompting an agent.

What can you build with loopy?

Find a published loop for keeping documentation current or improving test reliability. Scan your repository and coding history to turn repeated chores into a bounded loop. Audit a loop you wrote and fix weak checks or unclear stopping conditions. Run a loop overnight-style in bounded passes and review the receipt afterwards. Save team-approved loops in LOOPS.md so later sessions can reuse them.

A one-shot prompt asks an agent to do something once. A loop adds feedback: the agent acts, checks the result, uses what it learned, and either repeats or stops. This repo argues that bounded loops are easier to trust and reuse than open-ended instructions like "keep improving this".

The repository has two parts. One is the Loop Library website, a public catalog where people and agents can browse loops and copy their prompts, with no install needed. The other is Loopy, an optional skill that gives your agent a guided workflow on top of that catalog.

Loopy has nine paths: discover, find, audit (Loop Doctor), adapt, craft, run, debrief, save and publish. It works in bounded passes and returns a receipt of what it did. It does not start schedules, publish or send messages without your approval. Saved loops go into a LOOPS.md file in your project.

What it does

Published loop catalog
Each loop lists when to use it, a copy-ready prompt, how to verify success, steps, notes and related loops. Agents can also read a JSON or plain-text catalog.
Discover repeated work
Loopy scans a codebase and coding threads you put in scope for recurring work. It needs at least two thread occurrences before calling something repeated.
Audit, adapt and craft
Loop Doctor flags weak checks, unsafe actions or unclear stopping and repairs only material problems. Adapt tailors a loop to your tools. Craft interviews you to build a new one.
Run with receipts and debrief
Loopy runs a loop in bounded passes and returns a receipt with actions, evidence, outcome and stopping reason. A debrief then suggests the smallest justified improvement.
Save and publish
Save appends a loop to the project's LOOPS.md for reuse. Publish checks catalog overlap and submits only after you approve the exact preview.

What you could build

Find a published loop for keeping documentation current or improving test reliability.
Scan your repository and coding history to turn repeated chores into a bounded loop.
Audit a loop you wrote and fix weak checks or unclear stopping conditions.
Run a loop overnight-style in bounded passes and review the receipt afterwards.
Save team-approved loops in LOOPS.md so later sessions can reuse them.

Get started

Run the install command for your agent (Node.js and npx required), restarting the agent if Loopy doesn't appear. Then invoke it, for example with /loopy in Claude Code, and say what you want, such as finding a loop for test reliability. You can also just browse the website with no install.
