Our lab has been experimenting with “meta skills” that allow creation of skills to use later after a particular workflow.

Paper & applications published here: https://earthpilot.ai/metaskills/

I noticed a similar optimization path with skills, where I now have subagents to analyze the performance of a previous skill/command/hook execution, triggered by a command. I've pushed this to my plugin marketplace https://github.com/athola/claude-night-market

I have been experimenting with these same type of factory pattern skills. Thanks for sharing.
