What it does
Installs the whole pack of Anthropic's official skills as a Claude Code plugin — no laying out folders by hand. The anthropics/skills repository is published as the anthropic-agent-skills marketplace and contains three plugin bundles:
document-skills—xlsx,docx,pptx,pdf(office documents).example-skills—algorithmic-art,brand-guidelines,canvas-design,doc-coauthoring,frontend-design,internal-comms,mcp-builder,skill-creator,slack-gif-creator,theme-factory,web-artifacts-builder,webapp-testing.claude-api— a skill for the Claude API/SDK (also bundled into Claude Code itself).
How to set it up
In Claude Code:
/plugin marketplace add anthropics/skills
/plugin install document-skills@anthropic-agent-skills
/plugin install example-skills@anthropic-agent-skills
Plugin skills get a plugin:skill namespace, so they don't clash with your personal or project skills. A single skill can also just be copied as a folder into ~/.claude/skills/.
When to use it
- You want a fast "everything official at once" start with no manual setup.
- You want the office skills (Word/Excel/PPTX/PDF) in Claude Code in one command.
- Rolling out to a team: the plugin installs the same way for everyone.
Example
After /plugin install document-skills@anthropic-agent-skills, ask for "an Excel report with formulas from this data" — Claude picks up the xlsx skill and builds a workbook with real formulas instead of static numbers.
Security
A skill gives the model both instructions and code — install only from sources you trust (your own or Anthropic). Before trusting a project skill from someone else's repo, open SKILL.md and scripts/: a skill can grant itself broad tool access via allowed-tools.
