Identify and safely remove dead, unused, and unreachable code from codebases
What this skill does
# Dead Code Eliminator Skill
Identifies and safely removes dead code, unused functions, unreachable code paths, and orphaned files from codebases to reduce complexity and maintenance burden.
## Purpose
Enable safe dead code removal for:
- Codebase simplification
- Migration preparation
- Technical debt reduction
- Build size optimization
- Maintenance cost reduction
## Capabilities
### 1. Unused Function Detection
- Find uncalled functions
- Identify unused exports
- Detect unreferenced methods
- Map call graphs
### 2. Unreachable Code Identification
- Analyze control flow
- Find code after returns
- Detect impossible conditions
- Identify dead branches
### 3. Unused Variable Detection
- Find unread variables
- Identify write-only variables
- Detect unused parameters
- Flag shadowed variables
### 4. Orphan File Detection
- Find unimported modules
- Identify orphaned assets
- Detect unused configuration
- Map file dependencies
### 5. Safe Removal Verification
- Verify no runtime references
- Check dynamic imports
- Validate reflection usage
- Test after removal
### 6. Impact Analysis
- Estimate removal scope
- Calculate size reduction
- Assess risk level
- Document dependencies

venue-templates
IncludedAccess comprehensive LaTeX templates, formatting requirements, and submission guidelines for major scientific publication venues (Nature, Science, PLOS, IEEE, ACM), academic conferences (NeurIPS, ICML, CVPR, CHI), research posters, and grant proposals (NSF, NIH, DOE, DARPA). This skill should be used when preparing manuscripts for journal submission, conference papers, research posters, or grant proposals and need venue-specific formatting requirements and templates.
let-fate-decide
IncludedDraws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
