SKILLS.md or AGENTS are good concepts but they miss two crucial things that will make them much more usable. I predict that this will happen.
Each SKILLS.md will come with two hooks:
1. first for installing the SKILL itself - maybe install the CLI or do some initial work to get it working
2. Each skill may have dependencies on other skills - we need to install those first
Expressing these two hooks in a formal way in skills would help me completely replace MCP's.
My concrete prediction is that this will happen soon.
