To analyze an unfamiliar codebase, this Skill inventories the repository structure and identifies key modules and entry points. It traces execution paths and control flow to generate a fact-based mental model of the system architecture.

Tracing a request lifecycle is done by following data and control flow through the system. This Skill maps the path from the entry point through the service layer to the persistence layer using only actual code as evidence.

Code path tracing for onboarding works by automatically analyzing repository structure and execution paths. It reduces cognitive load by providing structured, fact-based navigation and architectural discovery for new developers.

No, you do not need write access to map repository structure and execution paths. This Skill requires only read-only access to source files to generate grounded, fact-based mental models of the system.

Yes, you can use this codebase analysis approach for documenting software systems. It applies to software engineering tasks involving architectural discovery, code path tracing, and generating system documentation.

You should not use evidence-based codebase mapping if you lack read-only access to the source files. The Skill relies entirely on accessing repository structure and analyzing actual code to generate grounded architectural insights.
