Claude SkillsLesson 2 of 15

Use Skills in Your Claude Account

Anthropic provides a library of ready-made skills you can install in your Claude.ai account — no SKILL.md files to write. Add them once and every conversation can benefit from that skill's capabilities.

Skills in Claude.ai vs Claude Code

Claude Code uses SKILL.md files you write yourself. The Claude.ai web account offers a simpler entry point: a built-in directory of Anthropic-provided skills you install with a single click.

Skills panel at claude.ai/customize/skills
1

Open the Skills directory

Go to claude.ai/customize/skills — or navigate to Customize → Skills in the left sidebar.

2

Browse Anthropic-provided skills

Click the + button to open the Directory. Filter by "Anthropic & Partners" to see officially maintained skills. Each card shows the skill name, install count, and a short description.

3

Click + to install

Click the + icon on any skill card to add it to your personal skills list. It appears immediately in the left panel. Use the toggle in the detail view to enable or disable it.

4

Use it in a conversation

Active skills can be triggered automatically when Claude detects a match, or explicitly with a slash command. The skill detail panel shows which trigger applies.

Skills installed in Customize are account-level — they follow you across all your devices and browsers. Toggling one off takes effect everywhere immediately.

Skill in action

With /web-artifacts-builder installed and active, a plain request like "build me a landing page" produces a full HTML artifact — no slash command needed. Without the skill, Claude would typically write a text description instead.

Claude applies an active skill without a slash command
If you have multiple skills installed, Claude picks the most relevant one for your request. It does not run every active skill on every message.

Anthropic-provided skills in the directory

These skills are currently available in the Anthropic & Partners section. The library grows — check claude.ai/customize/skills for the latest list.

SkillWhat it does

The exact skills available depend on your plan and Anthropic's latest release. Check the Directory in your account for the current list.

Tips for account skills

  • Install only what you use regularly — too many active skills can lead to unexpected triggering.
  • Toggle skills per work mode: enable /web-artifacts-builder for build sessions, switch it off for quick Q&A.
  • You do not need to type the slash command every time for auto-triggered skills — ask naturally.
  • Check the Trigger field in the skill detail panel: "Slash command only" means you must type /skill-name.

Before you continue

  • Directory: claude.ai/customize/skills
  • Install with + on a skill card; toggle on/off in the detail panel.
  • Account-level skills sync across all devices.
  • Trigger manually with /skill-name or let Claude auto-detect.
  • Next: explore ready-to-use skills in the Directory in detail.
