Qlty Code Quality

Universal code quality tool supporting 70+ linters for 40+ languages via qlty CLI.

When to Use

  • Check code for linting issues before commit/handoff
  • Auto-fix formatting and style issues
  • Calculate code metrics (complexity, duplication)
  • Find code smells

Quick Reference

# Check changed files with auto-fix
uv run python -m runtime.harness scripts/qlty_check.py --fix

# Check all files
uv run python -m runtime.harness scripts/qlty_check.py --all

# Format files
uv run python -m runtime.harness scripts/qlty_check.py --fmt

# Get metrics
uv run python -m runtime.harness scripts/qlty_check.py --metrics

# Find code smells
uv run python -m runtime.harness scripts/qlty_check.py --smells

Parameters

| Parameter | Description | |-----------|-------------| | `--check` | Run linters (default) | | `--fix` | Auto-fix issues | | `--all` | Process all files, not just changed | | `--fmt` | Format files instead | | `--metrics` | Calculate code metrics | | `--smells` | Find code smells | | `--paths` | Specific files/directories | | `--level` | Min issue level: note/low/medium/high | | `--cwd` | Working directory | | `--init` | Initialize qlty in a repo | | `--plugins` | List available plugins |

Common Workflows

After Implementation

# Auto-fix what's possible, see what remains
uv run python -m runtime.harness scripts/qlty_check.py --fix

Quality Report

# Get metrics for changed code
uv run python -m runtime.harness scripts/qlty_check.py --metrics

# Find complexity hotspots
uv run python -m runtime.harness scripts/qlty_check.py --smells

Initialize in New Repo

uv run python -m runtime.harness scripts/qlty_check.py --init --cwd /path/to/repo

Direct CLI (if qlty installed)

# Check changed files
qlty check

# Auto-fix
qlty check --fix

# JSON output
qlty check --json

# Format
qlty fmt

Requirements

  • **qlty CLI**: https://github.com/qltysh/qlty
  • **MCP server**: `servers/qlty/server.py` wraps CLI
  • **Config**: `.qlty/qlty.toml` in repo (run `qlty init` first)

vs Other Tools

| Tool | Use Case | |------|----------| | **qlty** | Unified linting, formatting, metrics for any language | | **ast-grep** | Structural code patterns and refactoring | | **morph** | Fast text search |
