Summary
Section titled “Summary”Skills are prompts designed to help agents perform specific tasks, and they are easy to share. With progressive disclosure, an agent is initially told which skills are available and where to find them. It loads a skill into its prompt only when needed, keeping task-specific instructions from cluttering the prompt in advance.
Key points
Section titled “Key points”- Skills are described as prompts, or “fancy prompts.”
- They are easy to share and can help agents focus on a particular task.
- Progressive disclosure means first giving the agent a little information about available skills.
- The agent can be told where to load a skill from when it decides it needs one.
- A PowerPoint skill can be loaded when the user asks for help generating a presentation from documents.
- Loading skills only when needed avoids cluttering the prompt with extensive task-specific instructions.

Full transcript (original language)
Section titled “Full transcript (original language)”00:00 What are skills and why do I keep hearing about them on X? - Yeah, it’s a great question. So skills are just prompts, they’re fancy prompts, but they’re really easy to share and they can help agents really narrow in and do a certain task well. And so I used the “progressive disclosure” buzzword earlier. And all that that means is you give the agent a little bit of information, like, hey, you have access to this write-PowerPoint skill and this code review skill. If you decide that you need them,
00:31 you can go load them from this location. And so then I’m like, oh no, I’m late for my meeting. Can you help me generate this PowerPoint with these docs? And then it’ll go and load in that skill into the prompt. And so you’re not cluttering your prompt with hundreds and hundreds of lines of PowerPoint-specific information. But when you need it, you can load it in. Got it.
