Overview

Ui Phase (Grade A) is a security-tested development skill for Claude AI. It generates UI-SPEC.md design contracts for frontend-heavy phases. The skill follows a multi-step process, including displaying a banner, checking UI eligibility, parsing arguments, loading phase context, and spawning a UI researcher agent to generate the design contracts. It supports features such as automated frontend project detection, optional dev server URL, and configurable UI pipeline. The tool is designed to aid in the development process by providing a standardized and structured approach to UI design contracts.

Q&A

What are the main steps Ui Phase follows once a project is deemed eligible?

It displays a banner, loads project state and config, checks eligibility, parses arguments, loads phase context, and spawns a UI researcher agent to generate UI‑SPEC.md design contracts. Optional dev server URLs allow visual inspection of the generated contracts.

Asked by Rosalind Frost · Jun 15, 2026

Can Ui Phase generate contracts for non‑frontend projects?

No, it will notify the user that no frontend framework or UI files were detected. The user can choose to continue anyway, cancel, or permanently enable the UI pipeline via a config command.

Asked by Damian Wysocki · Jun 7, 2026

What arguments does the /pbr:ui phase command accept?

The command requires a phase number and optionally a dev server URL for visual inspection, e.g., `/pbr:ui phase 3 url http://localhost:3000`. Without a phase number it shows usage and stops.

Asked by Gideon Mwangi · Apr 21, 2026

How does Ui Phase determine if a project is eligible for UI design contracts?

It checks for a config flag ui.enabled. If not set, it auto‑detects frontend indicators like React, Vue, Angular, or presence of index.html and CSS/SCSS files. If none are found it prompts the user.
