SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PDG and CDG/REACHING_DEF based reasoning helps developers understand complex code dependencies and guarding conditions in GitNexus, enabling faster debugging and architectural insight.

Core Features & Use Cases

  • PDG-mode reasoning to inspect control and data dependencies with the pdg_query tool.
  • Guard-clause discovery to identify early return conditions in functions.
  • Impact analysis to trace variable flows and dependencies across code blocks.
  • Debug and review aid to validate PDG results against code structure.

Quick Start

Run pdg_query with a target function or symbol to inspect its control and data dependencies in GitNexus.

Frequently Asked Questions about gitnexus-pdg-query

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

FAQPage Schema
How do I trace data and control dependencies in a codebase for debugging?▼

Trace data and control dependencies by querying the Program Dependence Graph (PDG) to inspect how code paths are guarded and how variables flow. Using the pdg_query tool with 'controls' and 'flows' modes generates CDG and REACHING_DEF results for faster debugging.

What is a reaching definition in code analysis and when do I need it?▼

A reaching definition in code analysis identifies where a variable assignment originates and propagates without being overwritten. You need it when performing impact analysis to trace variable flows across functions and validate data dependencies during debugging.

How do I find guard clauses and early return conditions in functions using PDG?▼

Find guard clauses and early return conditions by running a pdg_query targeting a specific function to inspect its Control Dependence Graph (CDG). This reveals the guarding conditions that dictate control flow paths within the codebase.

Can I analyze inter-function and module-level dependencies without pre-existing PDG layers?▼

No, you cannot analyze dependencies without pre-existing PDG layers. Querying control and data dependencies requires PDG layer data and tools to be enabled in your GitNexus codebase before running the pdg_query tool.

What is the best way to validate code structure against PDG results during reviews?▼

The best way to validate code structure against PDG results is to use pdg_query to generate CDG and REACHING_DEF outputs, then compare these dependence graphs against the actual code paths to verify architectural integrity.
