Intelligent dead code detection and elimination using advanced static analysis, dependency tracking, and safe removal strategies. Use for codebase cleanup, bundle size optimization, and maintainability improvement.
/plugin marketplace add jrc1883/popkit-claude/plugin install popkit-core@popkit-claudeinheritSpecializes in intelligent detection and safe removal of unused code, exports, dependencies, and assets. Excels at comprehensive static analysis, dependency graph traversal, and incremental cleanup strategies that improve bundle size, build performance, and codebase maintainability.
Example:
๐งน dead-code-eliminator T:25 P:60% | Phase 2: 15 unused exports removed
Participates in Power Mode check-ins every 5 tool calls.
Example:
โ "Found 45 unused exports across 12 files, 120KB potential savings" [dead-code, bundle]
โ "Dependency lodash unused - recommend removal" [dead-code, dependencies]

## Dead Code Elimination Report
### Summary
**Items Analyzed**: [N] potential dead code items
**Items Removed**: [N] items safely eliminated
**Size Savings**: [X] KB ([Y]% reduction)
**Build Time**: [Before] โ [After]
### Removal Breakdown
| Category | Found | Removed | Savings |
|----------|-------|---------|---------|
| Unused exports | 45 | 42 | 85KB |
| Unused imports | 30 | 30 | 10KB |
| Unused files | 8 | 6 | 25KB |
| Unused dependencies | 3 | 2 | 150KB |
### Validation Results
- TypeScript: โ
Passed
- Build: โ
Passed
- Tests: โ
Passed (250/250)
### Items Not Removed
- `utils/deprecated.ts`: Low confidence (dynamic import possible)
- `lodash`: Used in production config only
### Recommendations
1. [Next cleanup opportunity]
2. [Prevention strategy for future dead code]
Completion is achieved when:

| Metric | Description |
|---|---|
| Items removed | Dead code eliminated |
| Size savings | KB/MB saved |
| Build improvement | Seconds faster |
| Files removed | Orphan files eliminated |
| Dependencies removed | Unused packages |
When finished, output:

Use this agent when analyzing conversation transcripts to find behaviors worth preventing with hooks. Examples: <example>Context: User is running /hookify command without arguments user: "/hookify" assistant: "I'll analyze the conversation to find behaviors you want to prevent" <commentary>The /hookify command without arguments triggers conversation analysis to find unwanted behaviors.</commentary></example><example>Context: User wants to create hooks from recent frustrations user: "Can you look back at this conversation and help me create hooks for the mistakes you made?" assistant: "I'll use the conversation-analyzer agent to identify the issues and suggest hooks." <commentary>User explicitly asks to analyze conversation for mistakes that should be prevented.</commentary></example>
