Loopy

Loop Library is a public catalog from Forward Future of copyable agent prompts called loops. Each loop states what the agent should do, how to check its work, what to try next and when to stop. The site lists about 85 loops across engineering, content, design, evaluation, research and operations, contributed by Matthew Berman and others (for example a docs sweep, a production error sweep, a 100% test coverage loop and a multi-LLM convergence review).

Loopy is the optional companion skill in the same repository. Installed into a coding agent, it can discover repeated work in a codebase or thread history and turn it into a loop, find a published loop that fits a goal, audit or repair a loop, adapt it to local tools and limits, run it in bounded passes with a receipt, debrief runs, and save loops to a project LOOPS.md. It can also prepare a publication draft and submit it only after the user approves the exact preview.

The website can be browsed or handed to an agent without installing Loopy, via an agent guide, llms.txt, and JSON or plain-text catalogs. Loopy is installed with npx skills add for Codex, Cursor, Claude Code or other agents and requires Node.js. It is stated not to start schedules, change production, publish or send messages without the normal permissions and approvals.
