Code Graph Skill

Purpose: Use the code graph (codebase-memory-mcp) for sub-millisecond symbol lookup, function search, dependency analysis, and blast radius detection. This replaces brute-force grep and file reading for code navigation.

Core Principle

Graph first, file second. Before reading files or grepping, query the code graph. Only read full files when you need to modify them or need context beyond what the graph provides.

Consider graph when planning. When planning any change — feature, refactor, bug fix — start by querying the graph to understand scope, dependencies, and blast radius. This applies to thinking and planning
