Repository Cleanup Analysis
Methodology
- Explored repository structure to identify all files and directories
- Cross-referenced files with architecture documentation
- Identified orphaned, redundant, and duplicate files
- Categorized cleanup items by priority (CRITICAL, HIGH, MEDIUM)
- Created recommendations organized by category
Cleanup Execution
CRITICAL Items (~85MB removed)
- Python Virtual Environments (82MB)
personal_site/directory (40MB)utils/numpy/directory (42MB)- Rationale: Virtual environments should never be in repository
- macOS System Files
- All
.DS_Storefiles - Rationale: Already in
.gitignore, OS-specific artifacts
- All
- Repomix Output Files (Hundreds of files)
- All nested
repomix-output.xmlfiles - Preserved: Root
/repomix-output.xml(41MB reference file) - Rationale: Build artifacts scattered throughout directories
- All nested
HIGH PRIORITY Items (~1.4MB removed)
- Redundant Content Directories
reports/(988K) - Duplicate of_reports/collectionschemas-static/(196K) - Unused static JSON schemasresults/(132K) - Old schema analysis resultsdrafts/(120K) - Already in.gitignore
Impact Metrics
| Category | Items Removed | Space Saved |
|---|---|---|
| Python venvs | 2 directories | ~82MB |
| Repomix files | 100+ files | ~2MB |
| Content directories | 4 directories | ~1.4MB |
| System files | All .DS_Store | <1MB |
| TOTAL | ~4,813 files | ~85MB |

Automation Scripts Created
1. Repository-Specific Cleanup Script
Location: utils/cleanup-repository.sh Purpose: Automated cleanup for PersonalSite repository
Features:
- Interactive confirmation with size preview
- Color-coded output with progress indicators
- Detailed architecture verification
- Comprehensive summary report
- Executable:
chmod +x
Cleanup Tasks:
- Remove Python virtual environments
- Remove .DS_Store files
- Remove repomix files (keep root)
- Remove redundant directories
Documentation: utils/CLEANUP-SCRIPT-DOCUMENTATION.md (complete usage guide)
2. Universal Cleanup Script
Location: ~/code/jobs/sidequest/universal-repo-cleanup.sh Purpose: Portable cleanup script for any repository
Key Improvements:
- ✅ Works on any directory (takes path as argument)
- ✅ Automatic detection of bloat patterns
- ✅ Configurable via pattern arrays
- ✅ Universal compatibility (Jekyll, React, Python, etc.)
- ✅ Intelligent scanning (avoids false positives)
Cleanup Categories:
- Python venvs (venv/, .venv/, env/, custom)
- Temp files (.DS_Store, pycache, .swp, Thumbs.db)
- Output files (repomix, logs - keeps root)
- Build artifacts (.jekyll-cache, dist/, .next/, target/)
- Redundant dirs (drafts/, temp/, backup/, archive/)
Usage:
# Current directory
~/code/jobs/sidequest/universal-repo-cleanup.sh
# Specific path

Technical Challenges and Solutions
Challenge 1: Ruby Version Mismatch
Issue: Build testing failed due to Ruby version mismatch (system: 2.6.10, required: 3.2.0+)
Resolution:
- Documented as outstanding todo item
- Cleanup verified safe via architecture component verification
- Ruby upgrade deferred to future session (unrelated to cleanup work)
Challenge 2: Identifying Safe Deletions
Issue: Determining which files were safe to delete without breaking site functionality
Solution:
- Created comprehensive architecture documentation first
- Cross-referenced all files against documented data flows
- Verified all critical components present after cleanup
- Tested cleanup script with confirmation prompts
Challenge 3: Script Portability
Issue: Making cleanup script work for any repository, not just PersonalSite
Solution:
- Abstracted hardcoded paths to parameter-based approach
- Replaced manual checks with automatic pattern detection
- Made cleanup categories configurable via arrays
- Added intelligent scanning to avoid false positives
Best Practices Applied
Documentation
- Visual-First Approach: Diagrams before text descriptions
- Code Examples: Real, working examples from actual codebase
- Progressive Disclosure: Simple explanations → detailed breakdowns
- Cross-Referencing: Links to related docs and source files
- Timestamped: All documentation includes creation date
Cleanup Process
- Preview Before Deletion: Show sizes and counts before action
- Explicit Confirmation: Require “yes” to proceed
- Architecture Verification: Confirm critical components intact
- Comprehensive Summary: Detailed report of actions taken
- Recommendations: Suggest .gitignore updates
Automation
- Color-Coded Output: Visual feedback for success/warning/error
- Progress Indicators: Clear status updates (✓ ✗ ⚠ →)
- Error Handling: Exit on error, validate inputs
- Idempotent Design: Safe to run multiple times
- Configurable Patterns: Easy to customize for different repos
Lessons Learned
Architecture Documentation
- Document first, cleanup second - Understanding data flows prevented accidental deletions
- Visual aids are essential - Diagrams made complex flows understandable
- Real examples > theoretical - Using actual code from codebase provided clarity
Repository Maintenance
- Virtual environments don’t belong in repos - Even if .gitignored, still present if committed
- Build artifacts accumulate - repomix files were scattered throughout directories
- Duplicate content is common - Multiple directories serving same purpose (reports/ vs _reports/)
Automation
- Universal scripts need intelligent detection - Can’t hardcode paths for portable tools
- Confirmation is critical - Interactive prompts prevent accidental deletions
- Size calculations matter - Showing space savings motivates cleanup
Recommendations
Immediate Actions
- Update .gitignore - Add patterns to prevent reintroduction:
# Python virtual environments personal_site/ utils/numpy/ *.venv/ # System files (verify present) .DS_Store repomix-output.xml drafts/ - Run periodic cleanup - Monthly execution of cleanup script
cd ~/code/PersonalSite ./utils/cleanup-repository.sh - Review architecture docs - Use as onboarding guide for new contributors
Future Enhancements
- Pre-commit Hook - Automatically run cleanup before commits
- CI/CD Integration - Verify no bloat in pull requests
- Metrics Dashboard - Track repository size over time
- Automated Reports - Generate cleanup summaries automatically
Ruby Version Issue
Priority: Medium Action Required: Install Ruby 3.2.0+ via rbenv
# Install rbenv if needed
brew install rbenv
# Install Ruby 3.2.0

# Set for project
cd ~/code/PersonalSite
rbenv local 3.2.0
