    REFACTOR ADVISOR REPORT
    ════════════════════════════════════════
    File/Module: userService.js — processUser()
    Language: JavaScript (Node.js)
    Lines: ~20
    ════════════════════════════════════════

    TECHNICAL DEBT SCORE: 8/10
    Smells found: 7 total (3 critical · 3 medium · 1 low)

    QUICK WINS (each < 15 min)
    ────────────────────────────

    1. Line 2 — Magic String — extract 'secret_key_2024' to process.env.ADMIN_KEY
    2. Line 13 — Dead Code — remove duplicate const db2 = require('./db'); use existing db
    3. Line 1 — Poor Naming — rename u→user, t→type, r→role

    PRIORITY REFACTORS
    ──────────────────────────────────────────────────────
    #1 Severity: CRITICAL
    Smell: SQL Injection (Magic String in query)
    Location: Lines 6, 8, 10 — template literals inside db.query()
    Problem: String interpolation in SQL queries is not escaped. An attacker controlling
    u.email can exfiltrate or destroy the database.
    Fix: Replace with parameterized queries:

                  db.query('SELECT * FROM users WHERE email = $1', [user.email])
[... abbreviated ...]

    About this skill

    High-Level Code Quality Analysis

    Refactor Advisor is a specialized developer tool designed to bridge the gap between "working code" and "clean code." It acts as a deep-scanning auditor that identifies technical debt, structural flaws, and security risks using industry-standard patterns like SOLID principles and Martin Fowler’s refactoring catalog.

    What it does

    Unlike generic AI prompts, this skill applies a strict heuristic framework to your codebase. It categorizes issues from "Poor Naming" to "God Classes," calculates a quantitative Technical Debt Score, and identifies "Quick Wins" that provide immediate value with minimal risk.

    • Detailed Auditing: Scans for 10+ specific code smells including Feature Envy, Deep Nesting, and Magic Numbers.
    • Prioritized Reporting: Ranks issues by severity (Critical/Medium/Low) so you know exactly where to start.
    • Risk Management: Explicitly flags when a refactor requires "Tests First" to prevent silent regressions.
    • Framework Agnostic: Works across any language or environment, from legacy Node.js monoliths to modern Python microservices.

    Why use this skill

    Prompting a standard AI to "make my code better" often results in subjective style changes or dangerous rewrites. Refactor Advisor provides a structured report with exact line ranges and concrete transformation steps, ensuring that code quality is improved without breaking existing contracts or introducing security vulnerabilities like SQL injection.
