Variable Health Assessment

✅ Excellent (100+ uses)

All core variables are very well used across the codebase:

• text-muted, text-default (text hierarchy)
• border-default (primary border)
• bg-muted, bg-default (background hierarchy)

✅ Good (10-99 uses)

Strong usage for semantic states and accent colors:

• All accent colors (accent, danger)
• Text hierarchy (inverse, on-accent)
• Border variations (strong, danger, accent)
• Focus styling (ring)

⚠️ Light but Acceptable (1-9 uses)

Low usage but semantically necessary:

• text-success, text-warning, text-info: State indicators
• bg-info: Info banners/alerts
• border-info: Info borders
• bg-card: Semantic card backgrounds
• shadow-default: Used for elevation

✅ All Variables Justified

Every variable serves a semantic purpose and has real usage.

---

Semantic Organization

Core Hierarchy (Primary Use Case)

Backgrounds: default → muted → medium
Text: default → muted
Borders: default → strong

Inverse/Contrast

bg-inverse, text-inverse (light-on-dark, dark-on-light)

Brand/Accent

bg-accent, text-accent, text-on-accent, border-accent

Semantic States

danger: bg-danger, text-danger, border-danger
info: bg-info, text-info, border-info
warning: text-warning
success: text-success

Special Purpose

bg-card: Card container backgrounds
placeholder: Form input placeholders
ring: Focus indicator rings
shadow-default: Elevation/depth

Component-Specific

sidebar-*: Sidebar component theming (8 variables)

---

Ready for MCP Migration

Current Naming

bg-default, bg-muted, bg-medium
text-default, text-muted, text-inverse
border-default, border-strong

MCP Standard Naming

bg-primary, bg-secondary, bg-tertiary
text-primary, text-secondary, text-inverse
border-primary, border-secondary

Migration Strategy

1. Rename goose semantic names to MCP standard names
2. Map semantic states (danger, info, warning, success)
3. Add missing MCP variables (ghost, disabled, etc.)
4. Update Tailwind @theme inline mappings
5. Test all components with new variable names
