A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Publish AI-generated HTML and Markdown to a hosted, shareable URL. htmlbook is an MCP server and REST API that takes a document your coding agent just generated — an HTML report, a data dashboard, a spec, meeting notes, an interactive page — and turns it into a clean link you can open on your phone or send to someone, instead of leaving it as a local .html file buried in a project folder.
Push from Claude Code, Cursor, Codex, or claude.ai. htmlbook stores the document, re-themes it for comfortable reading on any device (paper / sepia / dark), keeps every edit as a version, and gives each document one share link with three modes — public (anyone, no login), password-protected (anyone with the password, no login), or a private secret link only you and your workspace can open.
Share the output as a link, not a file. When an agent makes HTML, the awkward part is everything after: getting it off your laptop, onto your phone, in front of someone else. htmlbook is the shelf that part lives on.

Just ask your agent. With the MCP server connected, it calls the publish tool:
You: Write up the Q3 numbers as a dashboard and put it on htmlbook.
Agent: htmlbook → publish
✓ shelved (hbdoc) · acme/q3-dashboard · v1 · read: https://htmlbook.io/app/p/acme/q3-dashboardProse (a report, a plan, notes) is easiest as Markdown — htmlbook keeps the .md as the source of truth and renders a themed reader view from it:
{
"tool": "publish",
"project": "acme",
"markdown": "# Q3 Review\n\nRevenue is up 8% QoQ...\n\n## Highlights\n- ..."
}Documents are private by default. Make one public to get a link anyone can open:
Agent: htmlbook → set_access (visibility: public)
✓ acme/q3-dashboard is now public · https://htmlbook.io/d/a1b2c3That's the whole loop: generate → publish → share.
| Format | When | What htmlbook does |
|---|---|---|
| Markdown | Prose: reports, plans, notes, specs | Keeps the .md as the source of truth, renders a themed reader view (TOC, tables, callouts, task lists), stays downloadable + editable as Markdown |
| hb-doc HTML | Rich docs: dashboards, KPIs, inline SVG charts | A <article class="hb-doc"> fragment styled only with hb-* classes + --hb-* tokens — the reader supplies the stylesheet and re-themes it (paper / sepia / dark, width, font size) |
| Bundle | A self-contained page with its own CSS/JS | Stored verbatim and rendered in a sandboxed iframe — your scripts run, your styling is preserved. Can be multi-file (index.html + sub-pages + assets, ≤10MB) for a small static site with working relative links |
The format is auto-detected at publish. You never have to declare it — push Markdown, push an hb-doc fragment, or push a full standalone HTML page and htmlbook routes it.
See docs/publishing.md and docs/hb-doc-contract.md.
htmlbook gets it onto your phone and into a shareable link.
themes it — the same document looks right on a phone in the dark and a desktop in daylight.
The History panel shows who changed what; any version restores.
original .md is the source of truth and round-trips on download.
public (anyone), password-protected (anyone with the password, no login — changing it revokes prior access), or a secret link session-gated to your workspace.
never pass back through your agent's context. See docs/rest-api.md.
The htmlbook MCP server exposes 10 tools. Full reference: docs/mcp-tools.md.

publish | Shelve a document (HTML or Markdown) to a hosted URL; new version if it exists |
