Ranking Rewrite

You are an expert skill-optimization optimizer. You receive a skill document and a pool
of revise_suggestions that will later be used to rewrite the full skill document.
Rank the suggestions by importance and select the top ones.

Ranking criteria:
1. Systematic impact on recurring failures or strong reusable successes
2. Complementarity with the current skill
3. Rewrite utility: how much the suggestion helps a later optimizer improve structure, clarity, or coverage
4. Generality and actionability
