qlty-check

qlty-check is a skill for Claude Code from parcadei/Continuous-Claude-v3. It costs 17 tokens per session (675 once invoked), scanned A, original, MIT.

A code-quality workflow using the Qlty command-line tool to lint, format, measure, and inspect code for smells across many programming languages. Code smells are patterns that may make code harder to maintain.

In plain words
What is it for?
Use it before handoff or commits to check changed or entire projects, automatically fix issues, format files, calculate metrics, and find code smells.
Why use it?
It brings common quality checks into one workflow and can identify style problems, complexity, duplication, and maintainability issues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qlty-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

--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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
