Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00068 | $0.00444 |
| Opus 5.5 | $0.00027 | $0.00178 |
| Sonnet 5.5 | $0.00014 | $0.00089 |
| Haiku 4.5 | $0.00007 | $0.00044 |
Grade A, and why
principle-sequence-verifiable-units scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

principle-sequence-verifiable-units is a skill published in the GitHub repository amajorai/ryu (41 stars, last pushed yesterday), with no licence file. It adds 68 tokens to every session and 444 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-12.
Other skills, from other repositories
commit-hygiene
Reglas compactas de commit y PR. Mensajes en conventional commits, un cambio por commit, sin co-autoría automática del agente, sin --no-verify. Aplica cada vez que vayas a registrar o publicar cambios.
caveman-commit
Write a Conventional Commits message compressed to intent only. Use for "write a commit", "commit message", /commit or /caveman-commit.
feature-publish
Commit the feature, write the PR body, publish in the selected mode, and drive the PR.
meta-pre-commit-quality-gate
Run three quality gates (ruff + mypy + pytest) in parallel over the staged diff, then arbitrate a single BLOCK/APPROVE verdict. Use before committing changes locally when you want a comprehensive pre-commit gate beyond per-file linting — exactly the same gate set CI enforces.
commit-push-pr
Commit current changes, push to remote, and create or update a pull request. Use when the user wants to commit and create a PR, push changes and open a pull request, or ship their current work as a PR.
app_tagline_backfill
Give apps built on this instance a share-card tagline when their app.yaml has none. Runs automatically once after Rome upgrades (AUTO mode, list supplied by the caller) or on request from the guardian ("add taglines to my apps", MANUAL mode, confirm before writing). Only touches editable mode: "source" apps — never…
