helix-audit-compare-total-skill-content-not-just-skill-md-size

When auditing whether a skill lost content during a quality pass, comparing only SKILL.md byte size produces false negatives for progressive-disclosure splits where content moved to docs/ or references/. The correct metric is total content across all skill files. In this audit, frontend-redesign showed a smaller SKILL.md but grew +1665B net; website-creator grew +612B net. Always diff total directory size or enumerate all files when verifying zero content loss.
