🔥 UI/UX Roast Skill

🔥 UI/​UX Roast Skill

Brutally honest UI/​UX critique with multi-perspective analysis and iterative improvement.

Command Syntax

/​roast [mode] [target] [options]

# Modes
screen <target>     # Single screen analysis (default)
flow <target>       # Multi-screen user journey
audit               # Full application review

# Options
--iterations=<1-10> # Roast cycles (default: 3)
--focus=<area>      # Priority: a11y|conversion|usability|visual|implementation
--output=<path>     # Output directory (default: reports/​roast/)
--fix=<mode>        # Fix handling: auto|report|ask (default: ask)

Examples

/​roast screen login                     # Roast login screen
/​roast screen settings --focus=a11y     # Focus on accessibility
/​roast flow checkout --iterations=5     # 5-iteration checkout flow
/​roast flow onboarding --fix=auto       # Auto-fix issues found
/​roast audit                            # Full app audit

Execution Workflow

1. Immediate Start

Do NOT ask questions upfront. Apply smart defaults and begin immediately.

🔥 ROAST SESSION STARTED
├─ Mode: screen
├─ Target: login
├─ Iterations: 3
├─ Focus: balanced
└─ Output: reports/​roast/

2. Screenshot Capture

Auto-detect screenshot method:

📸 Capturing screenshot...
├─ Xcode MCP: [✓ found | ✗ not found]
├─ Playwright MCP: [✓ found | ✗ not found]
└─ Using: [xcode | playwright | manual upload]

Detection priority:

1. mcp__xcodebuildmcp__screenshot → iOS/​macOS
2. mcp__playwright__browser_take_screenshot → Web
3. Request user upload → Fallback

CRITICAL: Always specify the output path explicitly!

// First, ensure directory exists
Bash: mkdir -p reports/​roast/​screenshots

// Playwright MCP - specify filename parameter
mcp__playwright__browser_take_screenshot({
  type: "png",
  filename: "reports/​roast/​screenshots/[target]_[iteration].png"
})

// Xcode MCP - specify path parameter
mcp__xcodebuildmcp__screenshot({
  path: "reports/​roast/​screenshots/[target]_[iteration].png"
})

Without explicit path, screenshots go to wrong location (e.g., .playwright-mcp/).
