-A chat that cannot install the skill is given `/h5p/skill/`, which lists every address. If it can run Node and fetch a file, it builds from the tool and a bundle in `/h5p/bundles/`. If it cannot, it gives the user a link to `/h5p/build/`, which builds in their browser.
+A chat takes the skill installed: from a zip in Claude, ChatGPT and Grok, or with `npx skills add` in an agent with a terminal, as `/h5p/create-with-ai/` says. Where the skill cannot reach npm, it builds from the tool and a bundle in `/h5p/bundles/`, at the addresses `/h5p/skill/` lists, if it can run Node and fetch a file: Grok did, on 2026-11-13. If it cannot, as in ChatGPT, it gives the user a link to `/h5p/build/`, which builds in their browser.
+
+Until 2026-11-13 the site's prompts sent a chat to read the skill at `/h5p/skill/` instead. That worked only in chats that now take the zip, so the prompts name the installed skill, and no page links to `/h5p/skill/`. Its page and files stay: the copies of the skill already installed name that address, and so do the prompts people copied before.
