Executable Python and validation inside skills

Today I dive into Anthropic’s latest feature that lets anyone create reusable workflows for Claude—no coding required. I break down exactly what Claude Skills are, how to build them from scratch, and how to use them inside Claude Code and Cursor to automate recurring AI tasks like generating PRDs, writing changelog summaries, and turning demo notes into follow-up emails.

What you’ll learn:

1. What Claude Skills are and how they differ from Claude Projects and custom GPTs
2. How to structure a Skill (metadata, instructions, and linked files)
3. Why defining workflows in natural language beats rigid automation tools
4. How to create Claude Skills using Claude Code and Cursor
5. How to validate your skills with Python scripts and folder references
6. How to upload and use Claude Skills inside Claude’s web or desktop app
7. Practical examples: turning changelogs into newsletters, demo notes into emails, and more
