2026-08-22Real installs from the skills.sh registry. Everything else falls back to repository stars, and says which of the two it is showing.## Four things Claude Code can load
Each is a different file shape with a different set of ways to be broken, so each is indexed and scored separately.
392,227
Skills
Folders of instructions Claude Code loads on demand, defined by a SKILL.md file.
80,636
Subagents
Named agents with their own prompt, model and tool allow-list, defined by a markdown file under agents/.
23,442
Plugins
Packaged bundles of skills, agents, hooks, MCP servers and LSP servers, installed from a marketplace repo.
7,265
Marketplaces
Repos that publish a .claude-plugin/marketplace.json at their root, which Claude Code adds as a plugin source with /plugin marketplace add.
What a README list cannot tell you #
The alternatives are an awesome-list nobody re-checks and a scraper that counts stars. Both answer “does this exist”. Neither answers “will this load”.
| The question | An awesome-list README | SkillWorks |
|---|---|---|
| Does the frontmatter parse? | Not checked | Checked on every artifact, every night |
| Are the files it references in the repository? | Not checked | Resolved, and listed by name where they are missing |
| How many are broken right now? | Unknown | 48190 of 503,570, published at |
How the score is built #
The full method Four weighted components, all four read straight from the repository. No execution, no model judging anything, no hand curation, and no way to buy a point.
40% of the score
Works
Does it parse, does it declare a name and a description, does it reference files that are actually there. A failure here is what sets the will-not-load verdict.
25% of the score
Maintained
Days since the last commit on the repository that publishes it, on a steep curve, and whether that repository has been archived.
20% of the score
Adopted
Install counts from the skills.sh registry where they exist; repository stars and 30-day star velocity where they do not.
15% of the score
Documented
Length of the instructions, worked examples, bundled scripts and references — how much a model actually has to go on.
48190 of them will not load #
All 48190 Popular, starred, and structurally broken. This is the half of the index the other directories do not publish, and it is most of the reason this one exists — these are the six with the largest audiences.

By what it is for #
All categories Assigned from the artifact’s own name, description and repository topics by deterministic keyword rules, applied fresh every night. Counts are of listings that pass every structural check.
Nobody else re-reads the files #
Every list of Claude Code skills was assembled once and has been decaying ever since. A repository is archived, a frontmatter block is edited into something that no longer parses, a referenced file is renamed — and the list recommending it stays exactly where it was. Nothing on it says whether any of it still works, because nothing on it ever checked.
This index reads the file. Every SKILL.md, every agent markdown file, every plugin and marketplace manifest is fetched from the repository that publishes it and put through the same structural checks Claude Code’s own applies, once a night. 48190 of the 503,570 listings here fail one of them, and they stay listed, with the check they failed named on the row — a directory that hides its own bad results is a list again.
The score is four measured components and nothing else. No model is asked whether a skill is good, nothing is executed in a sandbox, nobody curates, and sponsorship sits outside the ranking and cannot move a number. All of that is written down at /methodology before it says anything else.
