A zero-backend static web app to run any of the 172 skills directly in the
browser using the user's own Claude API key (stored only in localStorage,
sent straight to api.anthropic.com).
- build-skills.mjs: generates skills.json from skills/*/SKILL.md, parsing
frontmatter, the Required Inputs section (-> form fields), and a one-line
summary for each skill tile.
- Tile gallery with bundle tag, title, and one-line description; search +
bundle filter; click a tile to open an auto-generated input form.
- Streams output via the Anthropic Messages API (direct browser access),
with copy/download, model picker, and Show/Hide key toggle.
- Product Notes logo in the header.
- README: add Skill Playground section + screenshot, a table of contents,
and collapse the long changelog and full skills list into <details> blocks.
