My Frontend Slides skill now has 7.8k stars on Github which is crazy!! I just restructured it following the "progressive disclosure" pattern: went from 1,625 lines loaded every time to 183. Same functionality, 89% less context bloat. Treat your instruction file like a table of contents, not a textbook. Put the rules up front. Put the reference material in separate files the agent reads only when it needs them. It's like the difference between handing a new hire a 30-page briefing doc vs. a 2-page summary with "see appendix B for details."
