artifact-report

OUTPUT CONTRACT

Produces ONE .html file. Not markdown. Not .md. Not plain text.

Use templates from templates/. Inline artifact.css inside <style> (Mode B — single-file portable) or <link> to it. Use the class vocabulary from artifact-css/SKILL.md (.panel, .kv-strip, .timeline, .callout, .badge, .note, etc.) — never markdown syntax like # headings, | pipe tables |, or * bullets.

This holds even for "internal" or "working" reports. The shape is HTML, always. The file extension is .html, always.

Polished HTML reports: status updates, post-mortems, incident timelines, PR writeups. These all share the same shape - a header that says what this document is and when it covers, a one-block summary that someone scrolling through Slack can absorb in five seconds, then progressively more detail underneath.

Read artifact-css/SKILL.md first for the full OUTPUT CONTRACT, the design system, and the page skeleton.
