# Dependency Mapping > Map module dependencies and relationships. Use for complex codebases with non-trivial coupling.

Trace import/require statements across modules 2. Identify central or critical components (high fan-in) 3. Look for circular dependencies 4. Note tightly coupled areas 5. Document external dependency usage patterns ## Output Create `context/dependency-graph.md` using the template in `templates/dependency-graph.md`. ## Tips - Focus on logical dependencies, not every file - Highlight modules that many others depend on - Note any dependency injection patterns - Flag circular dependencies as potential issues --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/amattas) — claim your Tome and manage your conversions.
