SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Explain unfamiliar code by its place in the system, not just the file in front of you. This skill helps onboarding and rapid comprehension of architecture by situating code within subsystems and data flows.

Core Features & Use Cases

Context-first explanations: describe the subsystem, responsibilities, and interfaces before diving into lines.
Change-surface awareness: highlight blast radius, dependencies, and potential impact on other components.
Use Case: when onboarding a new codebase, provide a high-level map of callers, callee relationships, and data flow to ground exploration.

Quick Start

Provide a concise map of the call flow (callers → this → callees) and, if clearer, a simple data-flow diagram before delivering the explanation.

FAQPage Schema

How do I explain unfamiliar code in its system context during onboarding?▼

To explain unfamiliar code in its system context during onboarding, identify the subsystem, callers, dependencies, and data flows before diving into lines. This situates the code within the broader architecture and clarifies subsystem boundaries for safe modifications.

What's the best way to map code dependencies and data flow before modifying a subsystem?▼

The best way to map code dependencies and data flow before modifying a subsystem is to trace the call flow from callers through the target code to callees. A simple data-flow diagram clarifies the blast radius and surfaces interface considerations for safe changes.

Can I use system context mapping for code reviews to identify subsystem boundaries?▼

Yes, you can use system context mapping for code reviews to identify subsystem boundaries. By highlighting callers, dependencies, and data flows, reviewers can illuminate surface-area considerations and assess the blast radius of proposed changes.

Does zoom-out code explanation require knowledge of the entire system architecture?▼

Zoom-out code explanation does not require knowledge of the entire system architecture. It focuses on situating the specific unfamiliar code by identifying its immediate callers, dependencies, and data flows to provide a high-level map for rapid comprehension.

When do I need a context-first code explanation instead of a line-by-line review?▼

You need a context-first code explanation instead of a line-by-line review when onboarding to a new codebase or preparing to modify code. It provides the big picture of subsystem responsibilities and interfaces before examining syntax details.
