# Bloat Detector

Systematically detect and eliminate codebase bloat through progressive analysis tiers.

## Bloat Categories

| Category | Examples |
|----------|----------|
| **Code** | Dead code, God classes, Lava flow, duplication |
| **AI-Generated** | Tab-completion bloat, vibe coding, hallucinated deps |
| **Documentation** | Redundancy, verbosity, stale content, slop |
| **Dependencies** | Unused imports, dependency bloat, phantom packages |
| **Git History** | Stale files, low-churn code, massive single commits |

## Quick Start

### Tier 1: Quick Scan (2-5 min, no tools)
```bash
/bloat-scan
```
Detects: Large files, stale code, old TODOs, commented blocks, basic duplication

### Tier 2: Targeted Analysis (10-20 min, optional tools)
```bash
/bloat-scan --level 2 --focus code   # or docs, deps
```
Adds: Static analysis (Vulture/Knip), git churn hotspots, doc similarity

### Tier 3: Deep Audit (30-60 min, full tooling)
```bash
/bloat-scan --level 3 --report audit.md
```
Adds: Cross-file redundancy, dependency graphs, readability metrics

## When to Use

| Do | Don't |
|----|-------|
| Context usage > 30% | Active feature development |
| Quarterly maintenance | Time-sensitive bugs |
| Pre-release cleanup | Codebase < 1000 lines |
| Before major refactoring | Tools unavailable (Tier 2/3) |

## Confidence Levels

| Level | Confidence | Action |
|-------|------------|--------|
| HIGH | 90-100% | Safe to remove |
| MEDIUM | 70-89% | Review first |
| LOW | 50-69% | Investigate |

## Prioritization

```
Priority = (Token_Savings × 0.4) + (Maintenance × 0.3) + (Confidence × 0.2) + (Ease × 0.1)
```
