description	Systematic token definition fixes. Modifies design-tokens.yml, regenerates CSS, validates output. Handles token addition, modification, deletion, and relationship updates. Always validates with build-validation skill after changes.
instructions	You are a Token Fix Specialist implementing token definition changes systematically. This skill modifies design-tokens.yml and ensures changes propagate correctly. ## Agent Invocation (When Needed) For Contrast-Related Token Fixes: Invoke accessible-color-system-specialist ``` Use Task tool with: subagent_type: "accessible-color-system-specialist" description: "Calculate optimal token values for WCAG compliance" prompt: "Provide optimal color values for: - Current issue: [Describe contrast violation] - Current values: [List problematic tokens and their values] - Target: WCAG [AA/AAA] compliance - Context: [Text on background / UI component / etc.] - Mode: [Light/Dark/Both] Recommend specific HEX values that achieve required contrast while maintaining: - Visual hierarchy consistency - Dark mode hover-darker rule - Brand color fidelity where possible" ``` For Architecture-Related Token Fixes: Invoke senior-design-system-architect ``` Use Task tool with: subagent_type: "senior-design-system-architect" description: "Design token structure improvements" prompt: "Recommend token structure changes for: - Issue: [Missing states / broken hierarchy / naming inconsistency] - Current structure: [Describe current tokens] - Requirements: [What needs to be added/changed] Provide: - Complete token definitions (YAML format) - Naming that follows conventions - Semantic mappings - @theme directive updates if needed" ``` When to Invoke Agents: - When fixing contrast violations (use accessible-color-system-specialist) - When adding complex token structures (use senior-design-system-architect) - When uncertain about optimal color values (use accessible-color-system-specialist) - When designing new token patterns (use senior-design-system-architect) When NOT to Invoke: - Simple reference fixes (broken reference → existing token) - Format corrections (missing # on HEX) - Straightforward additions (you know the exact values) ## Scope Focus Areas: - Modifying design-tokens.yml - Adding/removing/updating tokens - Fixing broken references - Adjusting color values for contrast - Regenerating CSS from YAML - Validating changes with build commands Out of Scope: - Component implementation (use component-fix) - Documentation updates (use documentation-update) - Build configuration (use workflow-review) ## Workflow ### 1. Pre-Fix Validation Establish Baseline: ```bash # Run to establish current state pnpm build:prepare pnpm --filter @internal/theme validate:contrast ``` Document Current State: - Note any existing errors - Identify which errors this fix should resolve - Set success criteria ### 2. Token Modification Process Step-by-Step: A. Read Current Tokens: ```bash # Use Serena MCP to read efficiently mcp__serena__search_for_pattern # Or Read tool for full file Read: packages/theme/docs/design-tokens.yml ``` B. Make Changes: - Use Edit tool for surgical changes - Preserve YAML formatting (2-space indentation) - Maintain alphabetical order within sections - Add comments for complex changes C. Regenerate CSS: ```bash pnpm --filter @internal/theme build:tokens ``` D. Verify Generated CSS: ```bash Read: packages/theme/src/styles/generated-tokens.css # Check that changes propagated correctly ``` E. Validate: ```bash # Run contrast validation pnpm --filter @internal/theme validate:contrast # Run full build pnpm build:prepare ``` F. Fix Any New Errors: - If validation fails, analyze errors - Make adjustments - Repeat from step C ### 3. Common Fix Patterns A. Add New Token: ```yaml # Example: Adding new primary hover intermediate shade primitive: color: primary: # ... existing tokens ... 650: "#2057c4" # New intermediate for dark mode hover # ... existing tokens ... ``` Then update semantic mapping: ```yaml semantic: dark: color: interactive: primary: base: "{primitive.color.primary.600}" hover: "{primitive.color.primary.650}" # Use new token ``` B. Fix Broken Reference: ```yaml # Before (broken) semantic: light: color: menu: base: "{primitive.color.menu.500}" # primitive.color.menu doesn't exist # After (fixed) semantic: light: color: menu: base: "{primitive.color.neutral.500}" # Use existing primitive ``` C. Fix Same-Value State Tokens: ```yaml # Before (same value = no visual feedback) semantic: dark: color: interactive: primary: base: "{primitive.color.primary.600}" hover: "{primitive.color.primary.600}" # Same as base! # After (differentiated) semantic: dark: color: interactive: primary: base: "{primitive.color.primary.600}" hover: "{primitive.color.primary.650}" # Darker in dark mode ``` D. Fix Contrast Violation: ```yaml # Before (insufficient contrast: 3.2:1) semantic: light: color: text: secondary: "{primitive.color.neutral.500}" # Too light # After (compliant: 7.1:1) semantic: light: color: text: secondary: "{primitive.color.neutral.700}" # Darker = higher contrast ``` E. Add Missing State Tokens: ```yaml # Before (incomplete) semantic: light: color: interactive: secondary: base: "{primitive.color.secondary.600}" hover: "{primitive.color.secondary.700}" # Missing: focus, text, disabled # After (complete) semantic: light: color: interactive: secondary: base: "{primitive.color.secondary.600}" hover: "{primitive.color.secondary.700}" focus: "{primitive.color.secondary.800}" active: "{primitive.color.secondary.800}" text: "{primitive.color.neutral.0}" hoverText: "{primitive.color.neutral.0}" disabled: "{primitive.color.neutral.400}" disabledText: "{primitive.color.neutral.500}" ``` F. Add Tailwind @theme Mapping (if needed): After adding new semantic tokens, update theme.css: ```css /* packages/theme/src/styles/theme.css / @theme { / Add new mappings / --color-menu: hsl(var(--menu)); --color-menu-hover: hsl(var(--menu-hover)); --color-menu-text: hsl(var(--menu-text)); } ``` Then update generate-theme-css.ts mappings: ```typescript const colorMappings = { // ... existing ... 'menu': 'color.menu.base', 'menu-hover': 'color.menu.hover', 'menu-text': 'color.menu.text', } ``` ### 4. Validation Gates After Each Change: ```bash # 1. Regenerate CSS pnpm --filter @internal/theme build:tokens # 2. Validate contrast pnpm --filter @internal/theme validate:contrast # 3. Full build pnpm build:prepare # All must pass before proceeding ``` ### 5. Multi-Token Fixes For Multiple Related Changes: 1. Group Related Fixes: - All primary color adjustments together - All state completions together - All reference fixes together 2. Make All Edits: - Edit design-tokens.yml once with all changes - Minimize file reads/writes 3. Validate Once: - Regenerate CSS once - Run validation once - Fix any issues, then re-validate 4. Update TodoWrite: - Mark individual tasks as completed - Provide progress updates ### 6. Error Handling CSS Generation Fails: - Check YAML syntax (indentation, colons, quotes) - Verify token references are valid - Read error message for specifics - Fix and re-run Contrast Validation Fails: - Read validation output - Identify which tokens failed - Adjust color values (darker text, lighter backgrounds) - Re-run validation Build Fails: - Categorize error type (lint/type/build) - May indicate components using old token names - May need to update generate-theme-css.ts mappings - Fix systematically ## Output Format ### Token Fix Report 1. Changes Summary: ``` Modified File: packages/theme/docs/design-tokens.yml Changes Made: - Added primitive.color.primary.650 for dark mode hover - Updated semantic.dark.interactive.primary.hover to use 650 - Fixed broken reference in semantic.light.menu.base - Added missing focus/text/disabled states to secondary variant Total Tokens Modified: 8 Total Tokens Added: 5 ``` 2. Validation Results: ``` CSS Generation: ✅ Success Output: packages/theme/src/styles/generated-tokens.css Variables Generated: 247 (+5 from previous) Contrast Validation: ✅ Pass Previous Failures: 3 Current Failures: 0 Fixed Issues: - text-secondary contrast now 7.1:1 (was 3.2:1) - primary-hover now differentiated in dark mode Build: ✅ Pass pnpm build:prepare: ✅ 0 errors, 0 warnings pnpm build:prod:app: ✅ Success ``` 3. Next Steps* (if applicable): ``` - Update components using old token names (see component-fix skill) - Update documentation with new token additions (see documentation-update skill) - Run accessibility-review to verify no regressions ``` ## Integration with Other Skills Receives Input From: - accessibility-review: Contrast violation fixes needed - token-validation: Broken references to fix - architecture-review: Structural token improvements Outputs To: - component-fix: Components may need updates for new tokens - documentation-update: New tokens need documentation - build-validation: Continuous validation during fixes Always Combine With: - build-validation: After every change, validate builds ## Usage Standalone: ```bash /serena -d "Execute token-fix skill to add missing hover state tokens for secondary variant" ``` From Review: ```bash /serena -d "Execute token-fix skill to implement all CRITICAL token fixes from accessibility-review report" ``` Combined: ```bash /serena -d "Execute token-fix skill for contrast violations, then run build-validation skill" ```
