uilint-cli

Command-line interface for UILint - AI-powered UI consistency checking.

Overview

uilint-cli provides a powerful command-line interface for analyzing UI consistency, generating style guides, and validating your design system.

Installation

``bash


Install globally

npm install -g uilint-cli

Or use with npx

npx uilint-cli --help
`

Prerequisites

Ollama is required for LLM-powered features:

`bash


Install Ollama, then pull the default model


ollama pull qwen3-coder:30b
`

The CLI can auto-start Ollama and auto-pull models if needed. On macOS, it can optionally offer to run brew install ollama (interactive TTY only).

Commands

$3

UILint expects a style guide at .uilint/styleguide.md.

The recommended way to generate one is via Cursor:

`bash
npx uilint-cli install
`

Then run the Cursor command:

`
/genstyleguide
`

$3

Analyze HTML for UI consistency issues:

`bash


Scan an HTML file

uilint scan --input-file page.html

Scan with a specific style guide

uilint scan --input-file page.html --styleguide ./design/styleguide.md

JSON output (for CI/CD)

uilint scan --input-file page.html --output json

From stdin

curl http://localhost:3000 | uilint scan
`

> Note: The model used for LLM-based analysis defaults to the model configured in uilint-core. For ESLint-based semantic scanning (real-time linting), configure the model via the uilint/semantic rule options in your ESLint config.

Options:

| Option | Description |
| ------------------------- | ------------------------------- |
| -f, --input-file | Path to HTML file to scan |
| -j, --input-json | JSON input with html and styles |
| -s, --styleguide | Path to style guide file |
| -o, --output | Output format: text or json |

Example output:

`
⚠️ Color inconsistency
Similar blue colors should be consolidated
Current: #3575E2 Expected: #3B82F6
Suggestion: Use the primary blue #3B82F6 consistently

⚠️ Spacing issue
Button padding doesn't follow 4px grid
Current: 18px Expected: 16px or 20px
Suggestion: Use p-4 (16px) or p-5 (20px)

Analysis completed in 1234ms
`

$3

Ask questions about your style guide:

`bash


Simple queries

uilint query "what colors are allowed?"
uilint query "what fonts should I use?"

Complex queries (uses LLM)

uilint query "how should I style a primary button?"

JSON output

uilint query "what colors?" --output json
`

Options:

| Option | Description |
| ------------------------- | ------------------------------- |
| -s, --styleguide | Path to style guide file |
| -o, --output | Output format: text or json |

$3

Merge new styles into an existing style guide:

`bash


Update from HTML file

uilint update --input-file new-page.html

Use LLM to suggest updates

uilint update --input-file new-page.html --llm
`
