A comprehensive CLI tool that unifies various code formatting, linting, and quality assurance tools under a single command-line interface.

Documentation

🚀 Quick Start

# Install (choose one)
uv pip install lintro              # Python / PyPI (or: pip install lintro)
bun add -g @lgtm-hq/lintro         # Node / npm — self-contained, no Python

lintro check .                     # Find issues (alias: chk)
lintro format .                    # Fix issues (alias: fmt)
lintro check --output-format grid  # Beautiful output

✨ Why Lintro?

🎯 Unified Interface - One command for all your linting and formatting tools
📊 Consistent Output - Beautiful, standardized output formats across all tools
🔧 Auto-fixing - Automatically fix issues where possible
🐳 Docker Ready - Run in isolated containers for consistent environments
📈 Rich Reporting - Multiple formats: grid, JSON, HTML, CSV, Markdown
⚡ Fast - Optimized parallel execution

🔌 Works With Your Existing Configs

Lintro respects your native tool configurations. If you have a .prettierrc, pyproject.toml [tool.ruff], or .yamllint, Lintro uses them automatically - no migration required.

Native configs are detected - Your existing .prettierrc, .oxlintrc.json, etc. work as-is
Enforce settings override consistently - Set line_length: 88 once, applied everywhere
Fallback defaults when needed - Tools without native configs use sensible defaults

See the Configuration Guide for details on the 5-tier config system.

📦 = bundled with lintro — no separate install needed
⚡ Node.js tools support --auto-install to install dependencies automatically
🟨 Every Node.js tool resolves the same way: the checked project's node_modules/.bin first, then a binary on PATH, then a version-pinned bunx/npx fetch. A project devDependency (-D, shown above) is therefore always the best answer — it is lockfile-pinned and needs no network. A global (-g) or Homebrew install still works and is used when no local install exists. See Node.js tool resolution.

🤖 AI-Powered Features (Optional)

Lintro includes optional AI-powered features that provide actionable summaries and interactive fix suggestions. AI features are BYO (Bring Your Own) API key — not enabled by default.

Providers: Anthropic Claude, OpenAI GPT
AI Summary — high-level assessment with pattern analysis (1 API call per run)
Interactive Fix Suggestions — AI-generated code diffs with risk classification
Post-fix Summary — contextualizes what was fixed and what remains

# Install with AI support
uv pip install 'lintro[ai]'
export ANTHROPIC_API_KEY=sk-ant-...   # or OPENAI_API_KEY

# Enable in config
# .lintro-config.yaml
# ai:
#   enabled: true
#   provider: anthropic

See the AI Features Guide for full documentation.

# Run specific tools
lintro check --tools ruff,prettier,mypy

# Auto-install Node.js dependencies
lintro check --tools tsc --auto-install

# Exclude directories
lintro check --exclude "node_modules,dist,venv"

# Only scan files changed vs a git base ref (fast PR-scoped checks)
lintro check --diff              # vs the repo default branch (origin/HEAD)
lintro check --diff main         # vs an explicit ref
lintro format --diff             # format only changed files
