Hot-loadable capability packs that teach Claude specialized workflows.
Claude Skills are Anthropic's answer to the "every prompt starts from zero" problem. A Skill is a folder containing a SKILL.md file (instructions), optional scripts, and reference files that Claude hot-loads when relevant. Drop a "brand-voice" Skill into your account and Claude instantly writes in your voice. Add a "weekly-report" Skill and the correct format appears without prompting.
Who it's for: Power users, teams, and enterprises with repeatable workflows — brand voice guidelines, code review standards, financial report formats, legal memo templates, and more.
Write your workflow once in markdown — context, steps, examples, edge cases — and Claude follows it every time. No more copy-pasting the same system prompt.
Skills can bundle Python/Bash scripts Claude runs via the code execution tool. A "data-cleaning" Skill can actually run pandas, not just describe it.
Claude scans your available Skills and loads the right one automatically when the task matches. No manual selection, no context-switch friction.
Enterprise workspaces can share Skills across teams. Legal's memo format, Marketing's voice, Engineering's style guide — one source of truth.
Claude Skills are the most underhyped feature Anthropic has shipped. If you find yourself re-explaining the same workflow to Claude twice a week, a Skill will pay for your Pro subscription in saved time within a month.
