The TL;DR

You're at 83/100, solidly in B territory—this is good work. The rubric is based on Anthropic's best practices for skill structure and discoverability. Your Utility pillar is the strongest at 18/20 (you're solving a real problem that matters), but Progressive Disclosure Architecture and Ease of Use have room to tighten up.

What's Working Well

  • Solid utility score (18/20) — You identified a genuine pain point: understanding inherited Excel files is painful, and your forensic approach (Hard Errors → Soft Errors → Smells) adds real value
  • Clean file structure — Separating the overview (SKILL.md) from the pattern library (references/patterns.md) is the right call; minimal nesting, easy to navigate
  • Strong metadata — Your trigger conditions ("inherited", "legacy", "formula audit") are specific and actionable; the skill name follows conventions perfectly
  • Excellent examples — Full report template and error response templates show exactly what users get; patterns.md has rich archetypes

The Big One: Move the Report Template Out

Your 45-line report template (lines 73–118) lives inline in SKILL.md, and that's burning tokens on every load for something users rarely modify. This is the main thing holding your Progressive Disclosure Architecture score back (currently 26/30).

Fix: Create references/report_template.md and move the entire template there. In SKILL.md, replace it with a single line: "See references/report_template.md for the output format." That one change gets you +2 points in token economy an...
