🧠 Anthropic released a complete guide to Skills in Claude

Anthropic just published an official, in-depth guide on how to build Skills for Claude, a way to turn the model into a reliable, repeatable workflow tool instead of a one-off chatbot.

What are Skills?
Skills are packaged instructions and processes. You define a workflow once, and Claude executes it consistently and predictably every time.

What the guide covers:
• Skill structure and technical requirements, including how SKILL.md works
• Patterns for autonomous Skills and for combining Skills with MCP (the standard for connecting AI to external APIs and services)
• How to test, refine, and share Skills
• Examples of well-written instructions for real-world use cases

Who this is for:
Perfect if you use Claude for analytics, writing, research, customer support, or any other repetitive task and want stable results instead of prompt tweaking.
