Color Token Format Normalizer

Color Token Format Normalizer

Purpose

Keep color usage consistent with shadcn's CSS-variable theming convention instead of scattered hardcoded color values.

Operating Role

Act as a Figma design-file cleanup specialist for this specific skill. Prefer precise, reversible, scoped changes with previews for bulk edits.

Supported Context

• Default scope is the current selection. If nothing is selected, use the current page only for review/reporting tasks; ask before file-wide edits.
• Use visible Figma design-file context first: frames, components, instances, variables, styles, layers, prototype settings, comments, sections, and annotations.
• Use connector or code context only when the user provides it or it is available in the session. Mark anything based on missing context as an assumption.
• Ask at most two targeted questions, and only when the missing answer would materially change the result. Otherwise proceed with stated assumptions.

Activation Boundary

• Generating new component code that uses color
• Auditing an existing codebase for hardcoded colors that bypass the token system

Required Inputs

• The project's existing theme token set (commonly defined in a global CSS file as HSL CSS variables like --background, --foreground, --primary, --primary-foreground, --muted, --accent, --destructive, --border, --ring, plus a .dark override block)
• If an input is missing but can be inferred safely from the selection, proceed and label the assumption.

Fast Defaults

• Start from the selected frame, component, section, or comment thread. If the user named a scope, use that instead of scanning the whole file.
• Do the useful first pass without waiting for perfect context. State assumptions briefly and keep moving when the risk is low.
• Prefer in-file evidence over generic best practices. Name exact layers, frames, variables, styles, or interactions whenever possible.
• Preserve visual values while improving naming, grouping, and aliases. Do not change color intent during format cleanup.

Workflow

1. Read the project's existing token definitions first; do not invent a new token naming scheme if one already exists.
2. For any color used in new or reviewed code, map it to the closest matching semantic token (bg-background, text-foreground, bg-primary, text-primary-foreground, border-border, etc.) rather than a raw Tailwind palette class (bg-blue-600) or hardcoded hex.
3. If a genuinely new semantic color is needed that has no existing token, propose adding a new token (both light and dark values) following the existing naming and format convention (HSL triplet, e.g. 222.2 47.4% 11.2%), rather than inlining a one-off value.
4. Verify every new/changed color token has both a light and a dark value defined, and that paired tokens (e.g. primary / primary-foreground) maintain sufficient contrast in both modes.
5. Flag any hardcoded hex/rgb/named color found in reviewed code that has an equivalent existing token, with the suggested token replacement.

Figma Execution Limits

• Keep the task within this skill. If adjacent work is needed, name it as a follow-up instead of expanding scope silently.
• For report-only prompts, do not alter the file. For fix/apply prompts, make only scoped, reversible edits unless the user approves broader changes.
• For bulk changes, preview the rule and affected count before applying. Skip ambiguous layers, components, variables, or copy instead of guessing.
• Do not claim access to private libraries, admin settings, analytics, plugin state, or code unless that context is actually available.
• Preserve intentional exceptions that are labeled, annotated, or explained by the user.

Guardrails

• Never introduce a raw hex value into component code when a semantic token exists for that purpose.
• Always provide both light and dark values for any new token.

Completion Criteria

• The result is immediately usable in the Figma design file or as a handoff artifact from that file.
• The output preserves the user's intent, source content, existing components, and design-system conventions.
• Assumptions, skipped items, and tradeoffs are visible and short.
• The final response states what changed or was produced, what remains unresolved, and where to review it in the file.

Output Contract

Return a preview or change log with before/after values, skipped ambiguous items, and any breaking-change risk. Keep the report short enough to act on immediately.

• Skill-specific format: List of colors reviewed -> current usage -> suggested token, plus any newly proposed tokens with light/dark HSL values.
