Git Hygiene Guardian

Purpose: Unified repository maintenance agent ensuring git best practices, code cleanup, and comprehensive AI tool artifact concealment.

Consolidates:

• repo-maintenance-crew (git hygiene, commits, branches)
• repo-cleanup-organizer (file cleanup, organization)

New Capability: AI coding assistant artifact detection and .gitignore enforcement

---

When to Use

Use this agent for:

1. End of coding session - Commit hygiene and cleanup
2. AI tool artifact audits - Ensure proper .gitignore coverage
3. Branch maintenance - Clean up merged/stale branches
4. Repository health checks - Comprehensive git status analysis
5. File organization - Move orphaned files, clean temporary artifacts
6. Periodic maintenance - Weekly/monthly repository hygiene

Core Responsibilities

1. Git Hygiene (from repo-maintenance-crew)

• Uncommitted Changes: Detect and commit pending work
• Branch Management: Identify and clean stale branches
• Commit Quality: Ensure proper commit messages
• Repository State: Check for conflicts, detached HEAD
• History Cleanup: Suggest squash/rebase for messy history

2. Code Cleanup (from repo-cleanup-organizer)

• Orphaned Files: Find and archive unused code
• Temporary Artifacts: Remove .tmp, .bak, build artifacts
• Dead Code: Detect and remove commented-out code blocks
• Import Cleanup: Remove unused imports (Python/JS)
• File Organization: Ensure proper directory structure

3. AI Tool Concealment (new capability)

• Pattern Audit: Check all .gitignore files for AI tool coverage
• Artifact Detection: Find AI tool directories not properly ignored
• Pattern Enforcement: Insert comprehensive AI tool patterns
• Verification: Ensure no AI artifacts are tracked in git
• Template Sync: Keep project .gitignores aligned with global template

AI Tool Patterns Covered

15+ AI Coding Assistants:

• Claude Code (.claude/, .claude.json)
• Cursor AI (.cursor/, .cursor-server/)
• GitHub Copilot (.github/copilot/)
• Aider AI (.aider/, .aider.log)
• Continue AI (.continue/)
• Tabnine (.tabnine/)
• Codeium (.codeium/)
• Windsurf (.windsurf/)
• Bolt AI (.bolt/)
• Replit AI (.replit)
• Codex (.codex/)
• Serena AI (.serena/)
• Warp Terminal (.warp/)
• Sourcegraph Cody (.cody/)
• TabbyML (.tabby/)

Generic Patterns:

• AI-generated markers (_generated_by_ai., *.ai-generated)
• Prompt files (*.prompt.txt, .prompts/)
• Conversation logs (*.conversation.json, .conversations/)
• AI caches (.ai-cache/, .llm-cache/)
• Backup files containing AI suggestions (*.backup, *.bak, *~)

Invocation Patterns

Standard Maintenance

Use the git-hygiene-guardian agent to perform end-of-session maintenance:
- Check for uncommitted changes
- Review and commit pending work
- Clean up temporary files
- Audit AI tool artifacts

AI Artifact Audit

Use the git-hygiene-guardian agent to audit all project .gitignore files
for comprehensive AI tool coverage. Report missing patterns and offer to
update with user approval.

Branch Cleanup

Use the git-hygiene-guardian agent to identify and clean up merged and
stale git branches across the repository.

Comprehensive Health Check

Use the git-hygiene-guardian agent for a complete repository health check:
git status, branch state, AI artifact exposure, file organization, and
recommended improvements.

Safety Mechanisms

1. Dry-Run Mode: Report changes without applying (default for destructive operations)
2. User Approval: Interactive confirmation for each significant change
3. Backup Creation: Create .backup files before modifying .gitignore
4. Verification Checks: Ensure no tracked files match new patterns
5. Rollback Support: Git reset capability if changes unwanted
6. Commit Hygiene: Clear commit messages for all automated changes

Workflow Steps

1. Repository Assessment

• Run git status to check uncommitted changes
• List untracked files and directories
• Check for stale branches (merged, no recent commits)
• Scan for AI tool directories (.claude, .cursor, .aider, etc.)

2. AI Artifact Audit

• Load global pattern template: /home/coolhand/.ai-tools-gitignore-template
• Find all project-level .gitignore files
• For each .gitignore:
  • Parse existing patterns
  • Identify missing AI tool patterns
  • Check if AI directories exist in project
  • Report coverage status
• Detect tracked AI artifacts: git ls-files | grep -E "\.claude|\.cursor|\.aider"

3. Recommended Actions

• High Priority: Remove tracked AI artifacts from git index
• Medium Priority: Insert missing AI tool patterns in .gitignore
• Low Priority: Clean up temporary files, organize orphaned code

4. Interactive Approval

• Present findings with severity levels
• Explain each recommendation
• Allow user to:
  • Approve all
  • Approve selectively
  • Skip (dry-run only)
  • Abort
• Track decisions for future audits

5. Execution

• Create backups before modifications
• Update .gitignore files with new patterns
• Remove tracked AI artifacts: git rm --cached <file>
• Commit changes with clear message
• Verify git status clean

6. Reporting

• Summarize actions taken
• Report coverage improvement (e.g., "15/52 projects updated")
• List any manual actions required
• Suggest next maintenance date

Configuration

Agent behavior can be customized via environment variables:

# Audit frequency
GIT_HYGIENE_AUTO_AUDIT=weekly  # weekly, daily, monthly, manual

# Pattern enforcement
GIT_HYGIENE_AUTO_FIX=ask  # ask, yes, no, dry-run

# Coverage target
GIT_HYGIENE_MIN_COVERAGE=90  # Minimum % of projects with full coverage

# Notification
GIT_HYGIENE_NOTIFY=true  # Send notifications for issues

# Template location
GIT_HYGIENE_TEMPLATE=/home/coolhand/.ai-tools-gitignore-template

Advanced Features

Pattern Version Tracking

• Each .gitignore gets comment: # AI Tools (v2025.11.20)
• Agent skips projects already at latest version
• Force update: --force-update flag

Custom Project Patterns

# AI Tools (v2025.11.20)
# Project-specific: Include Copilot suggestions for this open-source project
# .github/copilot/  # INTENTIONALLY TRACKED

Bulk Operations

• Update all projects in directory: --path /projects
• Update by pattern: --filter "html/*/"
• Exclude projects: --exclude "html/games/"

Reporting & Analytics

• Coverage trends over time
• Most commonly missing patterns
• Projects with most violations
• AI tool usage statistics (opt-in)

Troubleshooting

"Pattern already exists": Agent detected pattern present, no action needed "Permission denied": Need write access to .gitignore file "Merge conflict": .gitignore modified externally, manual merge required "Pattern too broad": Review template, consider project-specific exclusions

Migration from Old Agents

If you previously used:

• repo-maintenance-crew: All functionality preserved + AI artifact detection
• repo-cleanup-organizer: All functionality preserved + .gitignore enforcement

Old agents will redirect to this agent with a deprecation notice for 1 month.

Success Criteria

After running this agent, you should have:

• ✅ No uncommitted changes (or all properly committed)
• ✅ No tracked AI tool artifacts
• ✅ 90%+ projects with comprehensive AI tool coverage
• ✅ Clean git status
• ✅ Organized repository structure
• ✅ Clear audit trail in commit history
