Skill Cabinet is a local catalog for agent skills installed on a machine. It scans user-level skill locations such as .agents, .claude, .codex, .cursor plugins, Hermes profiles, and other ~/.* /skills folders, then lets users filter skills by drawer, metadata, risk, invocation mode, and status; inspect rendered or source bodies, YAML frontmatter, extra files, symlinks, duplicates, origins, and broken links; and review disk usage. It runs with Node 20 or later through npx skill-cabinet, starting a server bound to 127.0.0.1 and opening the catalog in a browser. Users can quarantine skills to ~/.skill-cabinet/quarantine and restore them, or delete individual skills or groups; deletion removes folders, files, or symlinks from the scanned locations, while a symlink's target is retained. The project is distributed 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.

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.

self-learning-skills is a meta-skill for AI coding agents, including Claude Code, Cursor, Codex, and agents that read AGENTS.md or similar standing-instruction files. It recognizes hard-won, reusable procedures such as non-obvious commands and recurring operational workflows, then captures them as skills, rules, or project instructions for later sessions. The capture includes known dead ends and excludes one-off details and secret values. The project stores learned procedures as new skills/<name>/SKILL.md files for Claude Code, Codex, and Agent Skills clients; as .cursor/rules/learned/<name>.mdc files for Cursor; or in AGENTS.md or project notes for other agents. It can be installed with the community skills CLI, as a Claude Code plugin, or manually by copying the relevant files.

Skills for Real Engineers is an open-source collection of small, composable agent skills by Matt Pocock for disciplined software development with Claude Code, Codex, and other coding agents. The skills support requirements clarification, project-language setup, test-driven development, debugging, code review, specification, planning, triage, and codebase surveys. The collection includes skills such as `/grill-me` and `/grill-with-docs`, which question the user about a proposed change before implementation, and a setup skill that configures an issue tracker, ticket labels, and documentation storage for a repository. It can be installed as a managed Claude Code plugin or copied into a project as editable files through the `skills` installer; the skills are intended to work with any model and can be adapted by the user.
