What problem does it solve? Understanding unfamiliar or complex code requires hours of manual reading, and the resulting knowledge stays in one person's head. This Skill orchestrates a read-only deep-dive analysis that produces a comprehensive, diagram-rich report explaining how code works, why it is designed that way, and what potential issues exist. ## Core Features & Use Cases - Adaptive multi-agent research: Dispatches 1-3 parallel researcher agents (structure analyst, execution flow analyst, domain researcher) based on scope size and detected external dependencies. - Mandatory mermaid diagrams: Every report includes a high-level architecture diagram and a primary execution flow diagram, plus optional data flow, sequence, class, ER, state, and mindmap diagrams with strict quality checks. - Flexible scoping: Analyze by path, glob, git branch changes, working tree, or a free-text question like "how does the payment flow work". - Use Case: A developer joining a legacy project runs the skill on src/auth/ with the question "how does token refresh work" and receives a report with architecture diagrams, step-by-step execution traces with file:line references, design decision rationale, and observed potential issues. ## Quick Start Ask the assistant to explain how the WebSocket reconnection logic in src/auth/ works and write the report to the default output path.
