Author here. I've been tuning my Claude Code setup for a while and noticed most of the value comes from CLAUDE.md quality, hooks, and guard rails, not prompts.

Built a skill called /refine that audits your config across 8 dimensions and gives you a letter grade. It then interviews you about your workflow to generate rules that actually match how you work.

The skill is open and installable: https://skills.sh/meetdave3/refine-skill/refine
