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.
| Topic | Claude.ai account | Claude Code |
|---|---|---|
| Install | claude.ai/customize/skills | Create ~/.claude/skills/ folder |
| Source | Anthropic and partners | You write SKILL.md |
| Trigger | Slash command or auto | Slash command or auto |
| Files needed | None — click to install | SKILL.md in a named folder |
How to install a skill
Create new skills, modify and improve existing skills, and measure skill performance.
Open the Skills directory
Go to claude.ai/customize/skills — or navigate to Customize → Skills in the left sidebar.
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.
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.
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.
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.

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-builderfor 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-nameor let Claude auto-detect. - Next: explore ready-to-use skills in the Directory in detail.
