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

Run /sourceatlas:history for the entire repo, or /sourceatlas:history <path> for specific directory
Optionally specify time range: /sourceatlas:history . 6 for last 6 months
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"
