HTML

SkillFiles & storage

The html skill owns creating and revising durable, standalone HTML artifacts: a complete self-contained index.html saved in a requested or generated artifact directory, with inline dependencies, accessible structure, loopback serving, and exact-file verification. It triggers when a user asks to create, build, turn content or data into, save, revise, or update a “durable HTML artifact,” “one-file dashboard,” “single-page local artifact,” or named HTML artifact, or explicitly says “use /html” or “activate the HTML skill.” It does not trigger for integrating HTML into React or Next.js routing, reviewing or explaining HTML or accessibility, browser-based QA of an existing page, converting Figma designs into reusable components, or merely serving an existing dist directory.

Recipe

  1. Resolve ARTIFACT_DIR inside the provided HTML state root, or expanded ~/.html otherwise: revise a named artifact in place, or create a three-random-word lowercase slug for new work.
  2. Write only ARTIFACT_DIR/index.html as a complete self-contained, source-faithful, responsive interface with semantic structure and accessible controls unless the user names another entry file.
  3. Start a long-lived static server for ARTIFACT_DIR on 127.0.0.1 using a free non-common port.
  4. Verify the exact http://127.0.0.1:<PORT>/index.html with files inside the task run, retrying from step 3 on another port if binding or fetching fails, and keep the verified server alive through handoff.
  5. Reply with exactly HTML file: <absolute entry-file path> then HTML: [Open locally](<verified /index.html URL>); if serving cannot be verified, omit the link and give the path plus one concise reason.

Details

  • Run python3 -m http.server "$PORT" --bind 127.0.0.1 --directory "$ARTIFACT_DIR" as the foreground command of a long-running tool session; do not background or detach it from a shell that will exit.
