Loopy is a library and website of repeatable workflows that help AI agents learn from results and take the next useful step. It is for people and agents designing, finding, adapting, running, and reviewing structured agent workflows. Its catalogue add-ons provide an optional guided skill for working with the published loop collection.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02320 | $0.02320 |
| Opus 5.5 | $0.00928 | $0.00928 |
| Sonnet 5.5 | $0.00464 | $0.00464 |
| Haiku 4.5 | $0.00232 | $0.00232 |
Grade A, and why
loopy AGENTS.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Loopy Repository Operating Rules
This repository holds two separate but related parts:
- Loop Library website — the public catalog (site shell, database, and
rendering). All website code lives under
loop-library/(loop-library/site/,loop-library/worker/,loop-library/scripts/,loop-library/audits/). - Loopy skill — the installable agent skill in
skills/loopy/, with the compatibility alias inskills/loop-library/.
The operating rules below govern the Loop Library website unless they call out
the skill explicitly. Live URLs that contain /loop-library/ and the
loop-library-forms Worker name are deployed identifiers and do not change with
this repository layout.
Adding or editing loops
-
The production catalog database is the source of truth for public loops. The current Git tree holds application code and the content-free site shell. Do not commit published loop records, bootstrap data, generated loop pages, catalogs, feeds, sitemaps, or offline catalog fallbacks. Legacy public records remain in pre-migration Git history intentionally; do not rewrite shared history as part of routine catalog work.
-
Publish a reviewed loop from a JSON file outside the repository with:
LOOP_PUBLISH_TOKEN=... \ npm --prefix loop-library/worker run loop:publish -- /path/to/loop.jsonUse
loop-library/worker/examples/loop.jsonas the record template. The command validates the complete record before writing it, and the Worker records every revision. -
Every loop must have a stable slug, unique number, search title and description, contributor attribution, published and modified dates, practical context, verification criteria, category, keywords, and valid related-loop slugs.
-
Do not hand-edit the homepage, detail pages, catalogs, feed, sitemap, or Loopy skill content when publishing a database record. The Worker renders those public surfaces from the same record. New loops use the shared social card unless a reviewed HTTPS
socialImageUrlis supplied. -
Keep bootstrap and backup exports outside the repository with owner-only permissions. The one-time bootstrap command requires an explicit private file path; routine recovery exports use
npm --prefix loop-library/worker run loops:export. Restore an export only into a fresh empty catalog withnpm --prefix loop-library/worker run loops:restore; never overwrite a live catalog. -
Changes to the site shell, Worker, schema, or renderers still go through GitHub. Run the full repository checks before committing those code changes:
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

loopy AGENTS.md is an instructions file published in the GitHub repository Forward-Future/loopy (3,227 stars, last pushed 1mo ago), licensed MIT. It adds 2,320 tokens to every session, about $0.0093 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
