From the source SKILL.md

Drive an Apple Simulator (iOS, iPad, Apple Watch) from an agent using the [serve-sim](https://github.com/EvanBacon/serve-sim) CLI. serve-sim spawns a Swift helper that captures the simulator framebuffer via simctl io, exposes it as an MJPEG stream plus a binary WebSocket input channel, and serves a React preview UI on top. This skill teaches an agent the exact CLI surface, the gesture JSON shape, the gotchas, and the recommended workflows.

What this skill does

Serve Sim is a community-contributed Claude Code skill in the accessibility sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/serve-sim/ and loads when your prompt matches the skill's trigger.

The Serve Sim 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 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
