Skills work across Claude.ai, Claude Code, and the API. Claude identifies relevant Skills and applies them automatically. They can also stack together for complex workflows. - Claude can now use Skills to improve how it performs specific tasks. Skills are folders that include instructions, scripts, and resources that Claude can load when needed.
- Claude will only access a skill when itās relevant to the task at hand. When used, skills make Claude better at specialized tasks like working with Excel or following your organizationās brand guidelines.
- Skills are conceptually extremely simple: a skill is a markdown file telling the model how to do something, optionally accompanied by extra documents and pre-written scripts that the model can run to help it accomplish the tasks described by the skill.
- There is nothing at all preventing them from being used with other models. You can grab a skills folder right now, point Codex CLI or Gemini CLI at it and say āread pdf/SKILL.md and then create me a PDF describing this projectā and it will work, despite those tools and models having no baked in knowledge of the skills system.
