scrim is a small Go CLI + self-starting daemon that serves a directory of plain HTML/CSS/JS (or Markdown) at a local URL and live-reloads the browser tab whenever you write to it. Use it when you want the user to watch something render — a diagram, a mockup, a data view, a game-of-life toy — and no other app already provides that preview surface (don't reach for it to serve a real project's dev server; use that project's own tooling for that).
Scrim is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/scrim/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when you need to show the user something visual — a live HTML/CSS/JS preview, a canvas, a diagram, a mockup, or any rendered page — and there's no existing app to preview it in. scrim gives you a projection surface at a local URL that live-reloads as you write files, so the user can watch it update in their browser.
The Scrim Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/scrim/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Scrim is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
