Does this skill require specific project files?

The skill is optimized to work with project specifications and roadmaps (specifically spec-v0.3.md) to ensure implementation matches the intended design architecture.

How does this skill handle contrast failures?

It utilizes deterministic solver paths that respect strict or best-effort behavior flags, allowing developers to define how the system should react when a contrast target cannot be met.

What standards does the Contrast Solver Helper support?

It supports both the Advanced Perceptual Contrast Algorithm (APCA) and the Web Content Accessibility Guidelines (WCAG2) for color contrast validation.

Can this skill help with automated testing?

Yes, it is designed to help implement minimal tests for target attainment and failure handling to ensure accessibility logic remains stable.

Design Tools

Implements APCA and WCAG2 accessibility standards through deterministic color contrast solvers and validation logic.

The Accessible Contrast Solver skill is designed to streamline the implementation of complex color accessibility requirements within UI/UX projects. It enables Claude to accurately apply APCA and WCAG2 contrast algorithms, manage solver behaviors for specific color targets, and handle failure modes with deterministic logic. By referencing project-specific roadmap and specification files, this skill ensures that design systems maintain high legibility standards while providing automated testing for contrast compliance in frontend applications.
