SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a structured, in-depth explanation of a specific file, function, or module so engineers can quickly understand purpose, structure, and dependencies without reading the entire codebase.

Core Features & Use Cases

  • Targeted Graph + Source Lookup: Locates the component in the project's knowledge graph and enumerates its node data (id, type, summary, tags, complexity).
  • Neighborhood & Layer Analysis: Finds incoming and outgoing edges to reveal callers, callees, imports, and architectural layer membership.
  • Source-level Deep Dive: Reads the actual source file to explain internal structure, data flow, and notable patterns for debugging, onboarding, or design review.
  • Use Case: A developer onboarding onto a repo can ask for a deep explanation of src/auth/login.ts:verifyToken to learn its role, dependencies, and potential side effects.

Quick Start

Use the skill to analyze a target component by file path or filePath:name and produce a deep, contextual explanation of its role, internal structure, external connections, and data flow.

Frequently Asked Questions about understand-explain

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I get a deep explanation of a specific function in a codebase?▼

Analyze a specific code component by locating it in the project knowledge graph, inspecting incoming and outgoing edges, reading the source file, and synthesizing its role, internal structure, external connections, and data flow.

What is codebase component analysis using a knowledge graph?▼

Codebase knowledge graph analysis maps a specific component by locating its node data—summary, tags, complexity—and inspecting incoming and outgoing edges to reveal callers, callees, imports, and architectural layer membership.

How do I investigate code dependencies and external connections for a module?▼

Investigate code dependencies by analyzing the knowledge graph edges connected to a target node, revealing callers, callees, imports, and architectural layer membership for the module.

Can I use knowledge graph analysis for onboarding and architecture reviews?▼

Apply knowledge graph analysis to codebase components for onboarding, architecture reviews, debugging, and dependency investigation by locating target nodes, inspecting edges, and reading source files to understand component roles and data flow.

How do I analyze data flow and internal structure in a source file?▼

Analyze source file data flow and internal structure by reading the source code, inspecting knowledge graph edges for connections, and synthesizing notable patterns, external connections, and the component's role within the codebase architecture.

What are the limitations of using a knowledge graph for code explanation?▼

Knowledge graph code explanation requires a pre-existing .understand-anything/knowledge-graph.json file to locate node data and edges, meaning the codebase must be previously mapped before targeted source-level deep dives can be performed.
