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
