Code Smell Detector

PR-level code smell gating and trend tracking. Detects new smells introduced in a PR, blocks merge if smell density exceeds threshold, tracks file-level smell trends over time, and generates weekly maintainability reports. Use when enforcing code quality standards in CI or monitoring technical debt accumulation.

File contents

Code Smell Detector Plugin

Quality gates on every PR. Trend tracking over time.

Commands

/code-smell-detector setup       — configure CI quality gate
/code-smell-detector pr          — analyze smells introduced in current PR
/code-smell-detector trend       — show smell density trend (last 30 days)
/code-smell-detector hotspots    — files with worst smell density
/code-smell-detector report      — weekly maintainability report

PR Gate

Blocks merge if PR introduces:

New god class (>300 lines, >10 methods)
Method longer than 50 lines
Duplication of >15 lines found elsewhere in codebase
3 new magic numbers

CODE SMELL PR CHECK — PR #247

  [WARN] src/utils/checkout.ts:45 — method too long (78 lines)
  [WARN] src/utils/checkout.ts:12 — magic number 86400 (seconds/day?)

Trend Report

  src/components/AdminPanel.tsx  2.9/100  ↓ improving

Weekly Report

Generated every Monday:

Overall smell density vs last week
Top 5 files added/removed from hotspot list
Recommended refactors ranked by impact
Team velocity correlation (high smell density = slower feature delivery)

Pairs with /code-smell skill for deep interactive analysis.
