Loop Library

Loop Library has two separate but related parts in this repository:

The website is the library; Loopy is a companion way to work with it. You can browse or give an agent the website without installing Loopy. Installing Loopy adds the guided workflow, but it does not install or host the website.

Agents that do not have Loopy can use the published agent guide, agent instructions, JSON catalog, or plain-text catalog directly.

Each published loop tells an agent what to do, how to check its work, what to try next, and when to stop.

What is a loop?

Most prompts ask an agent to do something once. A loop gives the agent a way to learn from the result and take the next useful step.

For example, a one-shot prompt might say:

Make this website faster.

A loop adds the feedback that makes the work repeatable:

Find the slowest page, make one focused improvement, and measure it again. Keep the change only if it helps. Repeat until every page meets the target or another pass stops producing a meaningful improvement.

Think of a loop as a playbook with feedback built in. It is useful when the first attempt probably will not be the final answer, such as fixing production errors, improving test coverage, reviewing a product, or keeping documentation current.

A good loop answers four simple questions:

• What is the agent trying to accomplish?
• How will it know whether the latest attempt worked?
• What should it do with what it learned?
• When should it finish or ask for help?

Why loops are powerful

AI agents can move quickly, but an open-ended instruction like "keep improving this" leaves too much room for guessing. A loop gives the work a clear finish line and a consistent way to judge progress.

That makes the work easier to trust and easier to repeat. The agent can compare results instead of relying on confidence, keep improvements instead of merely making changes, and stop when it succeeds or stops making progress. The same loop can also be reused by another person or agent without rebuilding the workflow from scratch.

Loops are not permission for an agent to run forever. The best ones are deliberately bounded. They include a real check, a clear stopping point, and a moment to hand control back to a person when judgment or approval is needed.

What Loopy does

Loopy gives your agent direct access to the ideas in the library. You can use it to:

• Discover repeated work in a codebase, coding threads, or both and turn the strongest qualified candidate into a loop.
• Find a published loop that fits what you are trying to get done.
• Audit an existing loop for weak checks, unsafe actions, or unclear stopping behavior, then repair only the material problems.
• Adapt a useful loop to your tools, limits, and definition of success.
• Interview you about what you want to accomplish and what success looks like, then craft a new loop through a short, plain-language conversation.
• Run a loop in bounded passes and return a receipt with the actions, evidence, outcome, and stopping reason.
• Debrief completed runs and recommend the smallest evidence-backed improvement.
• Check a loop for catalog overlap, prepare a publication draft, and submit it only after you approve the exact preview.
• Turn the result into a compact prompt you can use right away.

Loopy checks the live catalog when it recommends a published loop. It does not quietly start schedules, change production, publish content, or send messages on your behalf. Those actions still require the normal permissions and approvals.

Install Loopy

You need Node.js and npx. Pick the platform you use:

To install it for all three at once:

npx skills add Forward-Future/loop-library \
  --skill loopy \
  --agent codex \
  --agent cursor \
  --agent claude-code \
  -g -y

Using another agent? Run the interactive installer and choose from the agents it detects:

npx skills add Forward-Future/loop-library --skill loopy -g

The command parts mean:

• Forward-Future/loop-library is the GitHub repository to install from.
• --skill loopy selects this skill from the repository.
• --agent ... selects the agent that should receive it.
• -g makes it available in all your projects. Leave -g off to install it only in the current project.
• -y accepts the install prompts. Leave it off if you want to review the choices interactively.

If an agent was already open and Loopy does not appear, restart that agent.

The previous loop-library skill name remains available as a compatibility alias for existing installations. Use loopy for all new installations and explicit invocations.

Invoke Loopy

The slash-command experience differs slightly by platform:

• Codex: type /skills, choose Loopy, then enter your request. You can also mention it directly with $loopy.
• Cursor: type / in Agent chat, search for loopy, select it, and add your request. You can also type /loopy directly.
• Claude Code: type /loopy followed by your request.

You can also describe a matching task normally. These agents can load the Loopy automatically when your request clearly calls for it, but explicit invocation is the most predictable way to start.

For example, in Codex you can write:

$loopy Analyze this codebase and my coding threads for repeated work, then turn the strongest candidate into a reliable loop.

Use Loopy

You do not need to know loop terminology. Invoke Loopy and say what you want to get done. It can take eight paths:

For example, in Claude Code or Cursor:

/loopy Find a loop for improving test reliability.

In Codex, choose Loopy from /skills, then send:

Find a loop for improving test reliability.

Discover loops from your work

Discovery looks for recurring engineering work in the sources you put in scope. In a codebase, that can include scripts, CI and deployment configuration, tests, runbooks, maintenance commands, and repeated lifecycle patterns. In coding threads, it groups equivalent completed work even when the wording differs.

Loopy requires at least two distinct thread occurrences before calling work repeated. A code pattern without run history is labeled as a potential loop, not proven recurrence. It then checks whether fresh feedback can change the next action, whether success can be verified, and whether the work has clear limits, stopping behavior, and approval boundaries. It also checks the live catalog to avoid recreating an existing loop.

Loopy can inspect only repositories and coding threads that your agent can access and that you place in scope. If thread history is unavailable, it uses the codebase evidence and says so. A discovery result includes compact source evidence and either a new loop, an adaptation of a published loop, a short candidate slate when your choice matters, or a clean no-op when nothing truly fits.

When Loopy finds or creates the right loop, it gives you a prompt to use with
