Anthropic, the company that makes Claude, keeps a public repo of Agent Skills with over 182,000 stars on GitHub. A skill is a folder of instructions, scripts and files that Claude loads only when a task needs it, so you get expert behaviour without writing the instructions yourself.

Here's what's inside, how to add it to Claude, the catches, and three prompts to try today.

What's inside (19 skills)

  • Documents: docx, pdf, pptx and xlsx. The README says these power Claude's own document features.
  • Design: frontend-design (Claude works like the design lead at a studio, no templated defaults), canvas-design, theme-factory, brand-guidelines, algorithmic-art.
  • Building: skill-creator (writes, tests and benchmarks new skills), mcp-builder, webapp-testing, web-artifacts-builder, claude-api.
  • Work: doc-coauthoring, internal-comms, slack-gif-creator, plus academy-guide and discernment-nudge.
