Render Proof

Category: Engineering  ·  Sub-category: cloud-platforms  ·  Last updated:
type:review
Render a Markdown file as a self-contained, offline HTML proof artifact styled for human review. Use when the user asks to "render this for review", "proof this draft", "give me a proof of this document", "show me this markdown rendered", or "make this readable for a reviewer". Outputs a single HTML file that opens in any browser with no server or network access at view time. Not for slides, presentations, or publication — use markdown-to-html for that. The rendered output uses a muted stone/slate palette deliberately distinct from the publication look.

From the source SKILL.md

A thin wrapper around scripts/render-proof.js. The renderer parses Markdown with markdown-it + markdown-it-task-lists, highlights fenced code with Shiki, sanitizes the result with DOMPurify (including a CSS url() allow-list hook), passes it through the A2UI Basic Catalog SSR pipeline (MessageProcessor → A2uiSurface → renderToStaticMarkup), and stamps it into a self-contained HTML file with the muted proof stylesheet. The output embeds all CSS inline and contains no JavaScript.

What this skill does

Render Proof is a community-contributed Claude Code skill in the cloud-platforms sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/render-proof/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks to "render this for review", "proof this draft", "give me a proof of this document", "show me this markdown rendered", or "make this readable for a reviewer". Outputs a single HTML file that opens in any browser with no server or network access at view time.
