Is the Web Motion skill free?

Yes. The skill itself is free from Schmandarine/web-motion-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Web Motion SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 4/5.

How do I install Web Motion?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Web Motion with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Environment: Claude Code 2.x (agent harness)

Ran the full loop for real: its Playwright script recorded a deliberately broken GSAP scroll page, and frame extraction proved the hero title was never fully visible in a single frame of a 9.7-second scroll — a fact code reading alone could only hedge about. After applying the skill's incoming/dwell/outgoing structure with matched power2.inOut eases, a second recording confirmed the title now holds fully readable for 30-plus consecutive frames, and the missing card stagger was equally visible on camera. One snag: the contact-sheet script requires an ffmpeg built with the drawtext filter, which this machine's build lacked; direct frame reading worked fine without it.

What Web Motion does

Closes the feedback loop for web animation work: bundled scripts record the page with Playwright while auto-scrolling, extract frames at 25fps, and build a contact sheet so Claude can measure timing, easing, and trajectory instead of guessing from code. Pairs the vision pipeline with Disney's 12 principles adapted for GSAP, CSS, and scroll-scrubbed input. Triggers on any animation add/debug/review request, including 'feels off' or 'too fast' descriptions.

How to install Web Motion

git clone https://github.com/Schmandarine/web-motion-skill ~/.claude/skills/web-motion

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Web Motion

/web-motion Records your page with Playwright and fixes animation timing frame-by-frame

It also activates on plain-language prompts like these:

This scroll animation feels off, can you record it and fix the timing?
The hero title flashes by too fast, diagnose the easing on it
My card stagger looks flat, check the frames and fix it
