Open 3D Skills

Video to Game is an open-source skill for coding agents that turns a short gameplay video into a playable Three.js browser game. The agent studies the video frame by frame, extracts a visual specification, generates matching images, 3D models, sound effects, and music through fal, writes the game as a standalone HTML file, and then playtests and records it with keyboard scenarios. It is distributed for Claude Code, Codex, Cursor, Gemini CLI, Copilot, and other agents through skill installation or copying. The workflow requires Python 3.9+, ffmpeg, Node 18+, Playwright Core, and a fal API key; the repository is MIT-licensed.

Three.js Game Skills is a set of self-contained Codex and Claude Code agent skills for building playable Three.js browser games. Its threejs-game-director skill routes work across gameplay, graphics, UI, asset generation, audio, debugging, and release verification, so users can request an outcome without manually selecting specialist skills. The package includes SKILL.md files, references, checklists, prompt templates, helper scripts, and a Vite, TypeScript, and Three.js scaffold. Generated games include deterministic test hooks and seeded randomness, with Playwright templates for smoke tests, visual-regression baselines, and bot playtests; the documented workflow also checks browser behavior, mobile viewports, visual output, UI, performance, and release readiness. It is created by Majid Manzarpour and can be installed for Codex or Claude Code through the skills CLI or the repository's installer.

Garden Skills is an open-source collection of installable Agent Skills for Claude Code, Cursor, Codex, Gemini CLI, OpenCode, and other AI coding agents. It includes skills for motion graphics and code-rendered video, web presentations, frontend design, GPT Image 2 generation and editing, source-to-article conversion, and local knowledge-base retrieval. Skills are self-contained folders centered on a SKILL.md file, with optional reference documents, scripts, assets, and templates; the repository also provides validation, release packaging, pinned ZIP archives with checksums, an npx skills CLI installation path, Claude Code plugin packs, manual copying, and Git submodule installation. The collection is distributed under the MIT license and is maintained through pull requests, release tooling, and CI validation.

Skills is a command-line tool for the open agent skills ecosystem. It installs reusable instruction sets defined in SKILL.md files into supported coding agents such as OpenCode, Claude Code, Codex, Cursor, and others. The `npx skills` CLI resolves skills from GitHub, GitLab, other Git URLs, local paths, or direct file and archive URLs; lists available skills, selects individual skills, and installs them project-wide or globally by symlink or copy. It can also generate a prompt for a skill without installing it, launch a supported agent with that prompt, search for skills, update or remove installations, and create new SKILL.md templates. Skills use YAML frontmatter with a name and description, and the CLI discovers them in standard agent and repository skill directories. The project is licensed under the MIT License.

simcraft is a collection of 24 Claude Code skills for video production, software engineering, learning, design, and planning. Each skill is a folder containing a SKILL.md that describes a working method, judgment calls, checks for the result, and tested scripts; Claude Code selects a skill when a user's request matches it rather than requiring the user to invoke the skill by name. The skills include three.js and shader loops, scripted screencasts, video editing, codebase mapping, regression bisecting, flaky-test investigation, benchmarking, API design review, threat modeling, paper-to-implementation work, brand-kit creation, and task routing. It is installed from the repository by linking its skill folders into ~/.claude/skills, and requires Python 3.9+, Node 18+ for browser or video-rendering skills, and ffmpeg for relevant workflows. The repository is licensed under MIT.
