Selection standard

Skill-first

This directory only includes skill repositories, skill collections, skill marketplaces, or skill specifications. General prompt lists, MCP server directories, API cookbooks, and broad AI tools are intentionally excluded.

Practical use

Each repository includes a task fit so visitors can decide whether it is worth opening or installing.

Safety first

Third-party skills may include scripts or external calls. Review SKILL.md, scripts, permissions, and recent commits before installation.

Star counts are editorial snapshots for rough orientation, not endorsements. External repositories are maintained by their own authors.

Maintenance notes

Human curation

This directory prioritizes repositories centered on Skills, SKILL.md, Claude Code Skills, Codex Skills, Nuwa, or Darwin-style methods.

What is excluded

Generic prompt lists, broad AI tools, unscreened MCP catalogs, empty repositories, exaggerated claims, and unclear safety boundaries are kept out of the main list.

Report changes

Practical guides

If you plan to install, adapt, or rely on third-party skills, these guides provide more context than a repository list alone.

How to evaluate an AI Skill Review SKILL.md, scripts, permissions, recent commits, and data risks before installing. Nuwa Skill vs Darwin Skill Understand how Nuwa creates or distills skills while Darwin evaluates and improves them. AI Skill Repository List Learn how to read a skill repository directory without treating it as a generic prompt list. Claude Code Skills Examples Study triggers, structure, references, and scripts in real skill examples. Darwin Skill Optimization Guide Improve skills with task sets, failure logs, and regression checks. Why local-first browser tools matter Decide which data belongs in browser-local tools and which should stay out of online utilities.

Safety checklist before installing

  • Read the root README and the SKILL.md files inside the skill directories first.
  • Check whether the repository includes scripts, install commands, shell files, or tools that access files or the network.
  • Do not give private keys, production tokens, or customer data to unreviewed third-party skills.
  • Try new skills inside a test project or isolated folder before adding them to a long-term workflow.
