Having a good prompt-engineering skill is the highest-leverage thing IMO, so I burnt 2 Max 20x usage windows to help Fable help me refactor mine. With its partnership we:

- Went deep on "what types of guidance even are there? what does giving good guidance mean?"

- Sampled my existing Claude guidance (CLAUDE.md, skills, hooks, etc.) and broke their guidance into "atoms"

- Categorized them by clustering, the same way Big Five was generated

- Generated a new candidate

- Then used independent agents to compare it against my existing corpus assuming that the new one would be worse

Working with it felt like working with a supersmart entity capable of generating very plausible-sounding but not-necessarily-true statements. The outcome certainly felt like an alien artifact, like nothing I'd make myself.

Only time'll tell if it holds up, but it sure had some interesting ideas.
