如何安裝 Claude Skill（逐步指南，2026 年）

Check your own account before assuming either way. 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. Where the Skills menu is not available you can still use a skill: open the SKILL.md, copy its contents, and paste them into the conversation or into project instructions. You lose automatic triggering and load it by hand each time, but the method itself is identical.

The most likely cause is that code execution is switched off. Turn on 'Code execution and file creation' under Settings then Capabilities. On Team and Enterprise an organisation owner controls that switch, so if it is off you have to ask them rather than flip it yourself. Plan availability is the thing to check second: 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 go by what your own account shows rather than by either page.

A folder with a SKILL.md at its root. That file carries YAML frontmatter with a name and a description, then the instructions themselves. A skill can also bundle extra markdown files, reference material and scripts, which Claude opens only when the task needs them.

The SKILL.md has to sit at the root of the archive, not inside a nested folder. Zipping the parent folder instead of its contents is the single most common cause of a rejected upload. Unzip your file and check the first level.

Yes, by pasting rather than uploading. Open the SKILL.md, copy everything, and paste it into custom instructions or a project. The instructions behave the same way. What does not carry over is the Claude Skills runtime, which triggers a skill automatically and loads bundled files only when needed.

Several. Each sits in the list with its own toggle, so you can switch them on and off independently. Only a skill whose description matches your request gets loaded into the conversation, so keeping a few installed costs you almost nothing.

Yes. Claude Code reads skills from the filesystem, so there is no upload step. Unzip into ~/.claude/skills// for a personal skill or .claude/skills// inside a project, then run /skills to confirm it loaded.

No. Anthropic documents them as separate surfaces. A skill uploaded in the Claude app is not available through the API, and a Claude Code skill is separate from both. If you want the same skill in more than one place, install it in each.

Treat it like installing software. Anthropic advises using skills only from sources you trust, and auditing anything from an unknown source before enabling it, because a skill can direct Claude to run code and use tools. Open the SKILL.md and any bundled scripts and read them first.
