helix-progressive-disclosure-split-increases-total-content
When refactoring a SKILL.md via progressive disclosure (moving deep content to docs/references/), the SKILL.md byte count shrinks but the total skill directory size must grow or stay equal — any net reduction signals content loss, not refactoring. frontend-redesign gained +1665B net and website-creator gained +612B net after splitting, confirming the pattern is additive. Use total-dir byte comparison, not SKILL.md-only, when auditing progressive-disclosure splits.
