Claude Skills Marketplace: Where to Find, Vet, and Install Skills

"Claude skills marketplace" is a search people make expecting an app store — a browsable catalog with ratings and one-click installs. The reality is both simpler and more open, and once you understand how distribution actually works, finding good skills gets much easier. Here is the real map of the ecosystem: where skills live, how marketplaces work, how to vet what you find, and what you should be willing to pay for.

What a marketplace actually is

Skills are folders of markdown, so distributing them is just distributing files. Claude Code formalizes this with plugins and marketplaces. A plugin is a bundle that can contain skills, subagents, slash commands, and MCP server configuration. A marketplace is a git repository with a manifest file listing the plugins it offers. You point Claude Code at a marketplace repository, and then you can install any plugin from it by name.

This means there is no single gatekept store. Anthropic hosts a marketplace, companies host internal ones for their teams, and individuals publish their own. It is closer to how apt or Homebrew taps work than to the App Store, and the consequences are worth internalizing: unlimited supply, no review process, and quality that ranges from excellent to abandoned.

The four places skills come from

1. Anthropic's own skills. The document skills — PDF, Word, PowerPoint, Excel — are open source and are the reference implementation of the format. If you want to see how a skill should be structured, read these first.

2. Plugin marketplaces. The one-command path. Add a marketplace repository, install a plugin, and its skills, agents, and commands all arrive together and stay updatable.

3. GitHub repositories. Vast, unsorted, and free. Awesome-lists and collection repos hold hundreds of skills of wildly varying quality, and copying a folder is a perfectly valid install method. Our guide to Claude skills on GitHub covers this route properly.

4. Curated paid kits. Bundles where someone has already done the reading, testing, and deduplication. What you buy is not the format — it is the filtering and the upkeep.

How to vet a skill in thirty seconds

Open the SKILL.md and check four things:

• The description names its triggers. If it does not say when to use the skill, Claude will not know when to load it — and it will sit installed and inert.
• The body is a procedure. Steps, checklists, worked examples. If it opens with "You are a world-class expert in…" and never gets concrete, it is a prompt wearing a skill's clothes.
• Mechanical work is scripted. Good skills bundle code for the deterministic parts instead of asking a model to re-derive them.
• It says what not to do. The best skills exist because a default behavior was wrong, and they name it.

Then read anything executable. This is the part people skip: a skill is instructions that Claude will follow with your permissions, in your repository, on your machine. Bundled scripts run as you. Apply the same suspicion you would to an npm package from an account with two commits.

Installing what you find

From a marketplace, installation is a command and updates come with it. From GitHub, you copy the folder into .claude/skills/ for one project or ~/.claude/skills/ for all of them — no build step, no registry, no package manager.

Either way, verify it loads. Ask Claude which skills are available, then phrase a request the way you naturally would and watch whether the right skill fires. When a skill does nothing, the description is nearly always the cause; the free SKILL.md validator catches the frontmatter problems that make a skill invisible, and this guide explains why triggering fails.

What is worth paying for

Nothing about the format is paywalled, so anyone selling "access to skills" is selling you air. What genuinely costs time — and is therefore worth buying — is curation and maintenance: someone reading forty repositories so you read none, deduplicating overlapping skills so they stop competing for triggers, testing that each one fires, and keeping the set current as Claude Code changes. That is the honest value proposition of a paid kit, and it is the one we make.
