Ten places worth knowing. We opened every one of them, counted what is actually there, and read the licence — the numbers below are ours, not theirs. 4 of the ten can be carried here; the rest are worth your time at the source, and we say why.
Anthropic's own skills — document handling, brand guidelines, canvas design, MCP builder.
The reference for how a SKILL.md should read. But we opened every LICENSE.txt: 19 of 20 say all rights reserved and forbid keeping copies outside Anthropic's services. Only frontend-design is Apache-2.0, so that is the only one we carry. Read the rest at the source.

Working habits for Claude Code: brainstorming, dispatching parallel agents, executing plans.
The highest-starred skill repo we found, and the skills are about how to work rather than what to type. Ships plugin manifests for Claude, Codex, Cursor and Devin.
14 skills★ 288k on the repo44 contributorsLicence: MIT
Skills grouped into plugins by job: python-development, cloud-infrastructure, security-scanning, llm-application-dev.
The largest permissively licensed set we could verify, and the plugin folders make the categories honest — they are the author's own grouping, not our guess.

The reference MCP servers: filesystem, git, fetch, memory, time, sequential thinking.
1,063 contributors — more than any other source here. If you are writing an agent that needs tools, start by reading these rather than a tutorial.
7 reference servers★ 90k on the repo1063 contributorsLicence: Apache-2.0
The protocol's own registry, with a public paginated API at /v0/servers.
The only directory here with an official API and no vendor behind it. We stopped counting at 4,000 because the cursor kept going.
4,000+ serversLicence: varies by server
The largest MCP index we found, with per-server security and quality scoring.
Biggest by a wide margin. Treat the size as a warning as much as a feature: most of those servers have never been used by anyone but their author.
88,617 serversLicence: varies by server
A directory that separates skills published by official teams from community ones.
The official-vs-community split is the useful part — it is the question you actually have when picking something to install.
~558 skills · ~365 agentsLicence: varies
A link list covering skills across seven agent platforms.
The widest net we found, and the only awesome list here that carries a licence. It hosts nothing itself — the repo is four files — so it is a map, not a warehouse.
228 repos linked★ 34k on the repoLicence: MIT
A short, opinionated list rather than an exhaustive one.
Short is the point: 37 entries someone chose, against lists with hundreds nobody has read. No licence file, so we follow the links and never copy the text.
37 repos linked★ 75k on the repoLicence: none declared
A broad community list, heavier on niche and non-English skills.
Turns up repos the bigger lists miss. Same caveat: no licence, so it is a map only.
