SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Understanding complex codebases, tracing multi-file flows, or debugging unfamiliar features can be time-consuming and challenging. This Skill automates deep code investigation.

Core Features & Use Cases

  • Multi-File Flow Tracing: Understand how data and control flow across multiple files and components.
  • Architecture Analysis: Identify architectural patterns, dependencies, and design decisions within the codebase.
  • Comprehensive Reports: Get detailed reports with primary locations, code flow, architecture maps, and insights.
  • Use Case: Ask "How does user authentication work in this app?" and receive a step-by-step explanation of the login flow, JWT generation, and middleware, complete with file paths and code snippets.

Quick Start

Use the deep-analysis skill to investigate "how user authentication works in this application".

FAQPage Schema
How do I trace how a feature works across multiple files in my codebase?

Multi-file flow tracing follows data and control flow across components to map how a feature executes. Deep analysis uses semantic search to locate implementations, track dependencies, and generate step-by-step explanations with file paths and code snippets showing the complete flow.

What's the best way to understand an unfamiliar codebase architecture?

Architecture analysis identifies patterns, dependencies, and design decisions within a codebase. It maps relationships between components, reveals how systems interact, and produces comprehensive reports that clarify the overall structure without requiring manual line-by-line reading.

Can I debug a feature by seeing how data flows through the application?

Yes. Flow tracing maps how data moves across multiple files and components, showing entry points, transformations, and outputs. This reveals where logic breaks or behaves unexpectedly, enabling faster root-cause identification in complex systems.

Do I need to read every file to understand how a specific feature works?

No. Semantic search and pattern matching locate only the relevant files and functions involved in a feature, then trace their interactions. You get a focused investigation report instead of reading through unrelated code.

What prerequisites do I need before analyzing a codebase?

The codebase must be indexed in your environment and the code search capability must be available. No special setup is required; the analysis workflow uses semantic search first rather than manual file reading.

How detailed are the reports from codebase investigation?

Reports include primary implementation locations, complete data and control flow diagrams, architecture maps showing dependencies, and annotated code snippets. Each finding references specific file paths, enabling direct navigation to relevant code sections.
