Anthropic has announced Claude Skills, a new tool customising its AI agents to perform specialised task-based workflows.
Anthropic announced Claude Skills on October 15, 2025, its latest tool for customising AI agents to perform specialised task-based workflows.
The technical documentation describes Skills as reusable, file-based, predefined prompt resources that give Claude domain-specific knowledge, workflows, and best practices, turning it from a general-purpose assistant into a task-specific expert.
New on the Anthropic Engineering Blog: tips for developers on using Agent Skills, a new way to extend Claude's capabilities with instruction folders, scripts, and resources.
Unlike general user prompts, which may give out one-time tasks or a call-out for information, Skills performs the tasks on demand and removes the need to repeat the same instructions across conversations within Claude.
