Create inline HTML documents with CSS and embedded JavaScript in Pioneer messages, including interactive calculators, charts, and small working interfaces. Do not use for ordinary application edits merely involving HTML.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Pioneer Inline HTML and JavaScript

Inline HTML supports CSS and embedded JavaScript that runs inside the document. Use JavaScript for working calculators, filters, tabs, scenario controls, and charts that respond to user input. Keep reading-focused documents static when interaction adds no value.

Use inline HTML to make relationships, comparisons, data, or interactive calculations easier to understand. Choose the form from the user's question: a document for reading, aligned rows for comparison, a diagram for relationships, a chart or table for data, or a small working interface for exploration. Plain text is sufficient for simple answers.

## Workflow

1. Prepare one complete HTML document with ready-to-run CSS and JavaScript. No TypeScript, TSX, or required build step.
2. When `html_preview` is available and image input is supported, call it using the callable name in the current runtime catalog.
3. For a successful preview, inspect all six real images and each frame's diagnostics: light at 360, 768, 1024 CSS px, then dark at the same widths. Correct clipping, overflow, contrast, layout, script errors, and truncated captures; preview again as needed.

How to install

The exact contents, by fingerprint
mdr add pioneerdotai/pioneer/html@sha256:970726242751dac3

The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
