SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires python3, jq, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Analyzing large codebases for dependencies, dead code, or impact assessment is token-heavy and slow for AI agents. This skill provides a token-efficient way to query a codebase's call graph, delivering precise JSON responses with file:line references, drastically reducing token usage and speeding up analysis.

Core Features & Use Cases

Blast Radius Analysis: Identify all functions affected by a change, with depth information, to assess refactoring impact.
Dead Code Detection: Find unused functions to streamline your codebase and improve maintainability.
Call Stack Tracing: Trace execution paths to specific error locations (file:line), aiding in rapid debugging.
Hotspot Identification: Pinpoint high-risk functions with many callers, guiding your testing and refactoring efforts.
Use Case: Ask "What is the blast radius of the parseDate function?" to instantly see all functions that depend on it, without reading thousands of lines of code.
