Code Investigator

Systematically investigate code to understand specifications and provide evidence-based reports with file/line references. Saves findings to persistent memory for future reference.

Core Capabilities

1. Evidence-based specification confirmation: Trace code to confirm actual behavior with file/line references
2. Visual flow documentation: Generate Mermaid diagrams for multi-file/complex flows
3. Persistent memory storage: Save investigation results in searchable format for future use
4. Uncertainty tracking: Clearly distinguish confirmed facts from unknowns

Investigation Workflow

Step 0: Plan (Brief)

State what to investigate and where to start (1-3 lines). Prevents scope drift.

Step 1: Identify Entry Point

Locate the starting point: routing, CLI entry, UI event, main function, service initialization, etc.
