html-explainer
Build a polished, lightly-interactive single-page web explainer for educational, informational, or explanatory content.
Going through the checklist
What it does
Build useful explainers: interactive, polished and educational. Lets a user land on a page and come away with new understanding, whether they skim or drill down.
Use when the user wants to explain, teach, summarize, or visualize a topic, concept, policy, dataset, process, or body of knowledge as an…
You don’t need to name it. Ask for the job in your own words — your AI loads the skill when the request matches.
What it can touch
Includes 4 scripts
Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.
How we know
Found in the skill’s folder: scripts/assemble.mjs, scripts/chat-dock.js, scripts/review-mode.js, scripts/shoot.mjs.
Its code sends data over the internet
A script in it uploads or posts data. That is normal for a skill that talks to a service — check that the address is the service you expect.
How we know
examples/encryption.html line 924: “fetch(req.url, { method:"POST", headers:req.headers, body:JSON.stringify(req.body) })”. Read 2026-10-05, commit 9b5bb05.
examples/encryption.html, line 924 ↗1 smaller thing worth knowing
Tells your AI to open private keys or password stores. Usually legitimate — listed so nothing is hidden.
How we know
Tells your AI to open private keys or password stores — examples/encryption.html line 237. Read 2026-10-05, commit 9b5bb05.
examples/encryption.html, line 237 ↗No serious risk pattern found
Launch7’s automated check read all 26 text files in this skill and matched none of its serious risk patterns. This is not a guarantee: a check like this can miss new or disguised tricks, and the author can change the files after the check.
How we know
Read 2026-10-05, commit 9b5bb05 by pipeline/trust/analyze.py — 40+ patterns for hidden text, prompt injection, downloads that run, credential access and more. It reads; it never runs the skill.
Recently maintained
Its repository has had changes recently.

Add it to your AI
Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.
Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.
In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.
Make sure code execution is switched on (Settings → Capabilities). Skills need it.
Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.
This skill ships 4 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.
