Skills feel so similar to specialized agents / sub-agentd, which we see some of already. I could be under appreciating the depth, but it feels like the main work here is the UX affordance: maybe like a mod launcher for games: 'what mods/prompts do you want to run with?'

I really enjoyed seeing Microsoft Amplifier last week, which similarly has a bank of different specialized sub-agents. These other banks of markdowns that get turned on for special purposes feels very similar. https://github.com/microsoft/amplifier?tab=readme-ov-file#sp... https://news.ycombinator.com/item?id=45549848

One of the major twists with Skills seems to be that Skills also have a "frontmatter YAML" that is always loaded. It still sounds like it's at least somewhat up to the user to engage the Skills, but this "frontmatter" offers… something, that purports to help.

> There’s one extra detail that makes this a feature, not just a bunch of files on disk. At the start of a session Claude’s various harnesses can scan all available skill files and read a short explanation for each one from the frontmatter YAML in the Markdown file. This is very token efficient: each skill only takes up a few dozen extra tokens, with the full details only loaded in should the user request a task that the skill can help solve.

I'm not sure what exactly this does but conceptually it sounds smart to have a top level awareness of the specializations available.

I do feel like I could be missing some significant aspects of this. But the mod-launched paradigm feels like a fairly close parallel?
