From the source SKILL.md

Create a frozen, independently servable snapshot of the validated prototype before development code begins to modify shared source files. The primary artifacts are a frozen prototype copy, CLAUDE.md guardrail rules that prevent agents from modifying prototype files, an optional PreToolUse hook for enforcement, and a git tag marking the prototype completion point.

What this skill does

Arn Spark Prototype Lock is a community-contributed Claude Code skill in the design-system-ui sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/arn-spark-prototype-lock/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Arn Spark Prototype Lock Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 185,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
