dr-huatuo 0.2.0

Code quality diagnosis toolkit — 5-dimension maintainability profiling for Python

dr-huatuo

Code quality diagnosis toolkit for Python. Named after the legendary Chinese physician Hua Tuo (华佗) — it diagnoses code health.

Features

• 5-Dimension Quality Profile: Maintainability, Complexity, Code Style, Documentation, Security
• CI Quality Gate: --fail-on D exits non-zero for CI/CD integration
• Literature-Backed Thresholds: McCabe, SonarSource, Microsoft/SEI, with evidence tagging
• 25 Static Metrics: ruff, radon, bandit, mypy, pylint, complexipy
• HTML Reports: Interactive complexity drilldown with source code view

Quick Start

pip install dr-huatuo

# Check a file
dr-huatuo check myfile.py

# Check a project with CI quality gate
dr-huatuo check src/ --fail-on D

# Generate HTML report
dr-huatuo report src/ -f html -o report.html

Example Output

myfile.py
  Maintainability    A  (MI=65.3)
  Complexity         C  (cognitive_complexity=18 > 15)
  Code Style         A  (ruff=0, pylint=9.2)
  Documentation      B  (docstring_density=0.75)
  Security           PASS

  Action items:
    1. Reduce cognitive complexity (18 → ≤15 for B)

Quality Dimensions

Dimension	Metrics	Thresholds
Maintainability	Maintainability Index (MI)	A: ≥40, B: ≥20, C: ≥10, D: <10
Complexity	Cognitive complexity + nesting depth	A: ≤5/≤2, D: >25/≥6
Code Style	ruff violations + pylint score	A: 0 violations + ≥9.0
Documentation	Docstring + comment density	A: ≥80% docstrings + 10-30% comments
Security	Bandit HIGH/MEDIUM findings	PASS/WARN/FAIL gate
