Code Flow Analyzer

Systematically trace the complete call chain of any feature or process in a codebase, from entry point to the deepest dependency, and produce a structured analysis document.

When This Skill Applies

• "这个功能的调用链是怎样的？"
• "Trace the request flow from X to Y"
• "How does feature Z work under the hood?"
• "Map the data flow of this process"
• "I want to understand the full path from user input to final output"
• Any question about how layers connect: frontend → API → service → domain → storage

Core Approach: Layer-by-Layer Tracing

Real-world codebases are layered. Each layer has its own conventions for entry points, routing, and delegation. Instead of guessing the architecture, discover it empirically by following the actual code paths.
