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 5.5 | $0.00064 | $0.02281 |
| Sonnet 5.5 | $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 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.
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 6mo ago), licensed Apache-2.0. It adds 161 tokens to every session and 5,703 once invoked, about $0.0006 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 2026-08-31.

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…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
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.
