The author speculates that bigger/smarter models interpreting vague directives to utilize general-function tools will outperform more precise and detailed directives to utilize narrow-function tools:

> Granted to use a skill the agent needs to have general purpose access to a computer, but this is the bitter lesson in action. Giving an agent general purpose tools and trusting it to have the ability to use them to accomplish a task might very well be the winning strategy over making specialized tools for every task.

I was thinking the same thing. Maybe is that at the end the author seems to imply that agentic AI will work simply because models have become better regardless of the way we make them agentic (i.e. MCPs, skills, etc).
