Apache-2.0 for code and CC-BY-4.0 for skills and docs.

motionmaxxing

An agent skill that plans, renders and checks motion graphics films such as launch films and product promos, using measured timing rules and scripted quality gates.

motionmaxxing official site: github.com/Tejashmakwana/motionmaxxing Source checked 7 Nov 2026, motionmaxxing official source

For: People who use Claude Code or another agent that reads a SKILL.md folder to make launch films, product promos or kinetic-type videos from HTML.
Access and use: Install for Claude Code with git clone https://github.com/Tejashmakwana/motionmaxxing ~/.claude/skills/motionmaxxing, then bash ~/.claude/skills/motionmaxxing/install.sh, which checks requirements and installs nothing system-wide. Other agents can be pointed at the folder and need shell access. Requires Node 22 or newer, Python 3, ffmpeg and Google Chrome. Films render locally from HTML, but the brand step captures the website you give it and the logo script fetches marks from SVGL, Simple Icons or that site. Voice, sound effects and music are optional and go through ElevenLabs, which needs an ELEVENLABS_API_KEY; generated surface plates optionally use the Codex CLI. The author describes it as an early release that has not had a wide test. The bundled GSAP is under the GreenSock Standard License, which is not open source, and other bundled components keep their own licences. Apache-2.0.

Teardown

A Claude Code skill that builds an interactive 3D simulator of a real machine as one offline HTML page and can record its tour to a 60 fps video.

Teardown official site: github.com/elvarofficial/teardown Source checked 7 Nov 2026, Teardown official source

For: Claude Code users who want to show how a machine or mechanism works as an interactive 3D model rather than describe it in text.
Access and use: Install with npx skills add elvarofficial/teardown -g -a claude-code, then run npm install && npx playwright install chromium once in the installed folder. Requires Node.js 20 or newer; recording video also needs ffmpeg, and the sound needs Python 3. Builds and renders are written to ./teardown-out in the folder you run from, and the finished pages run offline. The runtime, frame capture and sound engine come from whaleyxbt/claude-motion (MIT). MIT.

Elephant-Goldfish Model (EGM)

A plugin of agent skills from Google in which your coding agent drafts a software design specification with full project context, then fresh subagents that have not seen the conversation review it for missing assumptions and risks.

Elephant-Goldfish Model (EGM) official site: github.com/google/elephant-goldfish-model Source checked 7 Nov 2026, Elephant-Goldfish Model (EGM) official source

For: Developers using Claude Code, Codex, Antigravity or ChatGPT who want a design reviewed by fresh agents before they implement it.
Access and use: Claude Code: claude plugin marketplace add google/elephant-goldfish-model, then claude plugin install egm@egm. Codex CLI: codex plugin marketplace add google/elephant-goldfish-model, then codex plugin add egm@egm. Antigravity CLI: agy plugin install https://github.com/google/elephant-goldfish-model. ChatGPT and Codex desktop install the published plugin listing, and the setup guide covers Claude Cowork, ChatGPT Work, omp and Muse. Install the whole plugin, because installers that copy only the skills folder break it. Brainstorm and review need a host that can start fresh subagents, and the review stops if it cannot; standalone Antigravity IDE is not supported. A recorded Muse run used 15 fresh-context reviewers across one brainstorm and one review. The skills write briefs, drafts and reports into your working directory. The setup guide notes that Codex CLI and Antigravity CLI were reported passing project AGENTS.md or GEMINI.md files into reviewer context. Not an officially supported Google product. Apache-2.0.
