History Analyzer

When to Use

Trigger this skill when the user:

• Wants to find code hotspots (frequently changed files)
• Needs to identify who knows specific code areas
• Asks about bus factor or knowledge distribution
• Wants to find hidden coupling between files
• Asks "who should I ask about X"

Instructions

1. Run /sourceatlas:history for the entire repo, or /sourceatlas:history <path> for specific directory
2. Optionally specify time range: /sourceatlas:history . 6 for last 6 months
3. Returns hotspots, coupling analysis, and contributor distribution

Command Formats

• Full repo: /sourceatlas:history
• Specific directory: /sourceatlas:history src/
• With time range: /sourceatlas:history . 6 (last 6 months)

What User Gets

• Hotspots: Files with most changes (complexity indicators)
• Temporal Coupling: Files that always change together (hidden dependencies)
• Recent Contributors: Who knows what areas
• Bus Factor Risk: Single-contributor files
• Priority actions for refactoring

Example Triggers

• "What are the hotspots in this codebase?"
• "Who knows the payment module best?"
• "What files always change together?"
• "Is there any bus factor risk?"
• "Show me knowledge distribution"
