Importance: Medium. Core fix DONE and verified. Prevention follow-ups PENDING.

What this session resolved

It started as a request to rectify two off-brand design-skill folders in Downloads. It became a correction of the firm's master skill library. The earlier 2026-05-20 export is now superseded: that session rectified the Downloads copies, which a deeper look proved were stray duplicates, not the skills that actually load.

What was found

Skills live in many places. The canonical master is Documents/Projects/Skills (125 skills, not git-controlled). The active Cowork runtime .claude/skills (98 skills) is about 24 days behind it and does not contain the newer design skills at all.

What was done

  1. Backups: timestamped copies of every skill touched, in Downloads/Archives/ (master-design-skills-backup, adjacent-design-skills-backup, design-skills-inherits-backfill-backup, plus the earlier Downloads backups).
  2. sa-design-system v1.2: corrected the palette across all 7 drifted reference files to canonical sail-design-foundation tokens, preserving every v1.2 content change. general-elements.md kept as the intentional non-SA fallback. Added the inherits line.
  3. sa-design-elements: kept the master v1.1 SKILL.md, rebuilt the missing references/ folder. inline-snippets.html (elements 3.1-3.20 brand-clean, the two 3.12 CTA variants transcribed from sa-cta-image-banner, the canonical TOC from toc-design) and element-quick-card.md (all 29 elements). Added the inherits line. Every snippet pointer now resolves.
  4. Fixed adjacent drift: sa-cta-image-banner overlay rebuilt to the canonical overlay gradient; toc-design 4px radius corrected to 6px; a sticky-CTA where two buttons collided on the same orange.
  5. Prevention: backfilled inherits: sail-design-foundation on 9 design skills that lacked it. 28 skills now reference the canonical foundation.
  6. Archived the two Downloads stray folders into Downloads/Archives/superseded-downloads-design-skills-*.

Verified

Both master skills: canonical hex only, radius on-scale, banned values gone, inherits present, references folder restored, all 20 snippet pointers resolve. Adjacent skills clean.
