What problem does it solve?
It eliminates slow, error-prone navigation through large codebases by replacing brute-force grepping and repeated file reading with fast AST-backed symbol lookup and dependency-aware blast radius analysis.
Core Features & Use Cases
- Sub-ms symbol lookup & dependency analysis: Quickly find definitions, callers, and relationships so you can understand impact before you open files.
- Blast radius detection for safer changes: Identify which parts of the system are affected to prevent accidental breakage.
- Graph-first workflow for engineering velocity: A practical process for planning, locating, understanding, and verifying changes using the graph MCP tools.
- Use Case: Before refactoring an authorization middleware function, query the graph to identify all dependents and affected modules, then open only the specific files required to implement the change confidently.
Quick Start
Use the code-graph skill to answer “What are the definition, callers, and blast radius of function X in this repository?” before reading any files.
