The implementation of custom skills in Claude has a specific, non-obvious technical workflow. Users must generate the skill, download the file, rename it precisely to 'skill.md', compress it into a zip archive, and then upload it. This exact process is crucial for the feature to function correctly.
Users can now upload instructional files to teach Claude AI specific abilities. This allows the AI to perform complex, branded tasks like creating presentations or designing posters according to a company's unique style guide, effectively turning it into a personalized expert assistant.
Beyond using pre-made skills, users can simply prompt Claude to create a new skill for itself. The AI understands the required format and can generate the instructional text for a new capability, such as crafting marketing hooks that create FOMO. This democratizes the process of AI customization.
A key aspect of Claude's new feature is its ability to intelligently choose the right tool for the job. When a user makes a request, the AI automatically scans its library of uploaded skills and selects the most appropriate one without needing to be explicitly told, creating a seamless user experience.
