SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Getting oriented in an unfamiliar repository is slow and error-prone; this Skill provides a structured procedure for understanding how a codebase works, where functionality lives, and how data flows through it. ## Core Features & Use Cases - Guided Exploration Workflow: Starts from package.json/composer.json and README files, identifies entry points, and traces requests from entry to database. - Architecture Pattern Recognition: Notes dependency injection, repository, and service layer patterns while documenting findings in a summary. - Use Case: When joining a new project, ask the agent to trace how user authentication works; it will read the manifest files, locate entry points, follow the auth flow, and answer key questions about frameworks, databases, and test structure. ## Quick Start Ask the agent to explore this repository and explain how a specific feature or request flows through the code.

FAQPage Schema
How do I understand an unfamiliar codebase quickly?▼

Start with package.json or composer.json to learn dependencies, then read the README for project overview. Identify entry points like main or server files, and trace a request from entry to database while noting architectural patterns.

How to trace a request flow through a repository?▼

Locate the entry point files first, then follow the request path through routing, controllers, and service layers down to the database. Document each hop in a summary so the flow can be referenced later.

What questions should I answer when exploring a new repo?▼

Identify which frameworks and databases are used, how authentication is handled, how tests are structured, and what the deployment target is. These five questions give a solid architectural overview.

When should I use codebase exploration versus general research?▼

Use codebase exploration when the question concerns how a specific repository works or where code lives. For research outside the codebase, such as industry or library comparisons, use a research-oriented skill instead.
