Claude Code Skills — the Licence-Safe Directory

56 skills, subagents, and slash commands from 8 repos with explicit permissive licences. Every entry is safe to copy into your .claude/ directory.

Catalogue verified April 21, 2026

The short answer

The biggest community list — awesome-claude-code — is CC BY-NC-ND. You can link to it but cannot republish entries. This directory is the opposite: every skill comes from a repo with an MIT, Apache-2.0, BSD, CC0, or Unlicense licence. Copy, fork, adapt — no legal friction. Start with the High-signal tier; those earn their keep daily.

Repos we excluded (and why)

Transparency about licence. If you're surprised a well-known repo is missing, this section probably explains it.

hesreallyhim/awesome-claude-code

CC BY-NC-ND 4.0

No derivatives, no commercial reuse — safe to link, unsafe to republish entries.

Frequently asked

What is a Claude Code skill?+

A Claude Code skill is a reusable capability — a slash command, subagent, or skill file — that lives in your .claude/ directory and extends what Claude Code can do. Skills are markdown files with frontmatter describing when they fire and what they do. Unlike MCP servers (which add capabilities) or hooks (which enforce rules), skills package a workflow: 'when I type /commit, do these things'. Official spec: anthropics/skills on GitHub.

How is this catalogue different from awesome-claude-code?+

The biggest community catalogue — hesreallyhim/awesome-claude-code (39.9k stars) — is licensed CC BY-NC-ND. You can link to it but cannot republish entries. This directory is the opposite: every skill is from a repo with an explicit permissive licence (MIT, Apache-2.0, BSD, CC0, Unlicense) that allows reuse. You can copy any skill here into your own .claude/ without legal friction.

Can I use these skills commercially?+

Yes, with attribution where the licence requires it. MIT, Apache-2.0, BSD, CC0, and Unlicense all permit commercial use. MIT and Apache require you preserve the original copyright notice — so when you fork a skill, keep the 'Source: <author>' comment at the top. We exclude any skill from a repo with unclear or restrictive licensing.

How are skills different from subagents and slash commands?+

The lines blur. A slash command (~/.claude/commands/name.md) is a named prompt you invoke manually. A subagent (~/.claude/agents/name.md) is a specialist you hand work off to. A skill (~/.claude/skills/name/SKILL.md) is a bundle with richer frontmatter and sometimes scripts. This catalogue covers all three — what matters is the workflow, not the file type. See /skills-vs-mcp-vs-hooks for the deeper decision tree.

How often is this catalogue updated?+

Skills are re-verified quarterly. The lastVerified date is shown on the hub and on every skill page. Stars counts, last-commit dates, and source licence are checked on each re-verification. If a repo changes licence or goes dormant, entries are pulled or flagged.

How do I install a skill from this catalogue?+

Every skill page has a setup block — usually 2-4 steps. Typical flow: (1) save the .md file at ~/.claude/commands/<name>.md (or ~/.claude/skills/<name>/SKILL.md for bundled skills), (2) restart Claude Code, (3) invoke by typing the slash command. Full walkthrough on the Install guide page.

Can I submit a skill I've written?+

Not yet — this is a curated directory. If you've written a skill you want featured, publish it on GitHub with an MIT or Apache-2.0 licence, and mention @bryanjcollins on X with a link. Criteria for inclusion: clear licence, published for at least 30 days, at least one real-world use case, and not a duplicate of an existing entry.
