Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00156 | $0.01735 |
| Opus 5 | $0.00078 | $0.00868 |
| Sonnet 5 | $0.00031 | $0.00347 |
| Haiku 4.5 | $0.00016 | $0.00173 |
Grade B, and why
claude-design-animation-capture scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt install ffmpeg How it starts
The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Design Animation Capture
Convert a Claude Design Animation export (ZIP or unzipped folder) into a clean 1080x1920 H.264 MP4 ready for Reels, Shorts, TikTok, or any social upload.
Claude Design (Anthropic Labs, Research Preview) ships an Animation template that exports an HTML + JSX bundle, not a video file. This skill bridges that gap. It spins up a tiny local HTTP server to serve the React + Babel HTML, drives Playwright headless Chromium to record the playback at the requested dimensions, then runs ffmpeg to crop, trim, and transcode to a single MP4.
When to Use
- You exported a Claude Design Animation project as a ZIP and want an MP4 to upload to LinkedIn, Instagram Reels, YouTube Shorts, TikTok, or X.
- You want the same pixel-accurate playback the Claude Design preview shows, captured headlessly without screen-recording.
- You want a repeatable, scriptable pipeline — same input ZIP, same output MP4, every time.
Do NOT use this skill to:
- Capture Claude Design Wireframe, High Fidelity, or Slide Deck templates. They export different structures and don't have the timeline contract this skill relies on. Animation only.
- Render hosted Hyperframes URLs. Use the official Hyperframes CLI for those.
- Edit, trim, or merge multiple animations. This skill captures one export end-to-end. Compose afterwards in your editor of choice.
Prerequisites
Node 20+, plus two user-installed tools.
Playwright (and a Chromium binary):
# From this skill's folder, or anywhere you want a local install:
npm install playwright
npx playwright install chromium
ffmpeg on PATH:
# macOS
brew install ffmpeg
# Ubuntu / Debian
sudo apt install ffmpeg
# Windows
winget install Gyan.FFmpeg
# Then close and reopen your terminal so ffmpeg is on PATH.
The skill itself has zero npm dependencies. Playwright and ffmpeg are user-installed because bundling them would push the skill from kilobytes to ~300 MB.
Workflow
Phase 1, gather inputs.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

claude-design-animation-capture is a skill published in the GitHub repository Jody09-dotcom/constructionx-skills (1 stars, last pushed 4mo ago), licensed MIT. It adds 156 tokens to every session and 1,735 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
