2026 年最佳 Claude Skills 市集（比較 7 個，已確認價格）

It depends on what you want. For free skills and a one-command install, skills.sh and claudeskills.info have the widest catalogues, and Anthropic's own anthropics/skills repo and plugin directory are small but hand-reviewed. For paid skills carrying a published security scan, Agensi at agensi.io. For the cheapest bulk buy, Claude Protocol lists $99 for its 501 files. For a finished role-based specialist you install without touching a terminal, KissMySkills at $19 per skill. Figures re-checked against each vendor's own site on 17 September 2026.

Because they count different things, which is what makes most roundups of this subject misleading. The very large numbers come from crawling GitHub for files named SKILL.md, so they are a search index rather than a catalogue, and a filter such as at least two GitHub stars is a popularity threshold rather than a review. The small numbers come from catalogues where somebody wrote and maintains each file. Never compare the two without knowing which is which.

Both. skills.sh, claudeskills.info, LobeHub, SkillsMP and Anthropic's own directories are free and mostly community-contributed. Paid catalogues charge for files someone wrote and maintains: Claude Protocol lists $3.99 each or $99 for all 501, Agensi has free and paid listings side by side with paid ones seen at $5 to $19, and KissMySkills is $19 per skill, $39 per agent, prompt packs $9 and bundles from $39. Confirm on the vendor's own site before buying.

Skills need code execution enabled, under Settings then Capabilities. Anthropic's help centre currently lists Skills on Free, Pro, Max, Team and Enterprise, while its Academy tutorial lists Pro, Max, Team and Enterprise, so if you are on the free plan check Settings then Capabilities for your own account rather than trusting either page. Anthropic also uses the word Skills for two different things: its own pre-built Skills, and custom Skills meaning a ZIP you upload yourself, which is what every paid marketplace sells. Either way the deciding switch is Code execution and file creation, under Settings then Capabilities, or in organisation settings on Team and Enterprise. If you cannot enable it, or you are in ChatGPT or Gemini, paste the SKILL.md contents into custom instructions instead.

Read the file first. A SKILL.md is instructions handed to an agent that may be able to read your files, run commands and fetch URLs, and the large free directories index public repositories with little or no review. Agensi is the one marketplace in this comparison publishing an automated security scan, covering prompt injection, credential exfiltration, destructive shell commands and unexpected network calls, with the result shown on every listing. That is more than anyone else here publishes, ourselves included.

No, and this is the most important thing on the page. No marketplace anywhere, including KissMySkills, publishes a benchmark showing that a skill file improves results. There is no shared test set and no published before-and-after. Install counts measure curiosity rather than outcomes, so treat every catalogue size and popularity ranking as a measure of how much exists rather than how much is good.

A skill is a configuration file that changes how the model works across conversations once it is installed and switched on. A prompt pack is a set of prompts you paste one at a time for individual tasks, with nothing to install. An agent bundles a skill with an activation prompt that walks the model through a whole multi-step job rather than a single request. The price rises with scope, from $9 for a prompt up to $39 for an agent.

On KissMySkills, yes: files are delivered by email straight after checkout and you can request a full refund within 30 days. Refund terms differ on every other marketplace in this comparison, and free GitHub skills come with no support or guarantee at all, so check before you pay.
