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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00161 | $0.05703 |
| Opus 5 | $0.00081 | $0.02851 |
| Sonnet 5 | $0.00032 | $0.01141 |
| Haiku 4.5 | $0.00016 | $0.00570 |
Grade A, and why
paper-to-course 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 286 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Paper-to-Course
Transform any academic or research paper into a stunning, interactive single-page HTML course. The output is a single self-contained HTML file (no dependencies except Google Fonts) that teaches the paper's ideas through scroll-based modules, animated visualizations, embedded quizzes, and plain-English translations of equations and academic jargon.
First-Run Welcome
When the skill is first triggered and the user hasn't specified a paper yet, introduce yourself and explain what you do:
I can turn any research paper into an interactive course that teaches its key ideas — no academic background required.
Just point me at a paper:
- A PDF file — e.g., "turn ./attention-is-all-you-need.pdf into a course"
- An arXiv link — e.g., "make a course from https://arxiv.org/abs/1706.03762"
- A paper title — e.g., "make a course about the Transformer paper"
- A pasted abstract or excerpt — if you have the text handy
I'll read through the paper, extract the key ideas, and generate a beautiful single-page HTML course with animated diagrams, plain-English equation explanations, and interactive quizzes. The whole thing runs in your browser — no setup needed.
If the user provides an arXiv link, fetch the PDF first. If they provide a local PDF path, read it directly. If they give a paper title, search for it and confirm before proceeding.
Who This Is For
The target learner is a curious non-expert — someone who encountered an interesting paper (shared on social media, referenced in a blog post, cited in a meeting) and wants to actually understand what it says. They might be a product manager trying to evaluate whether a new technique is relevant, a journalist covering a scientific breakthrough, a student encountering a field for the first time, or simply a curious person who refuses to accept "just trust the experts."
Assume no domain expertise. Every technical concept — from p-values to attention mechanisms to gene expression — needs to be explained in plain language as if the learner has never encountered it. No jargon without definition. No "as is well-known in the literature." The tone should be like a brilliant friend who happens to have a PhD explaining things over coffee, not a professor lecturing.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

paper-to-course is a skill published in the GitHub repository cyyeh/skills-playground (2 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 161 tokens to every session and 5,703 once invoked, about $0.0008 per session on Opus 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 2026-08-31.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
miniapp
Build a tiny interactive HTML playground only when someone asks to see, play with, or step through a mechanism.
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
master-yinguang
A reference-based assistant for questions about Yinguang and Pure Land Buddhism, a Buddhist tradition focused on faith, ethical living, and practice connected with rebirth in the Pure Land. It can answer in Yinguang’s historical teaching style.
