# Dependency Graph Generator Skill

## Overview

Generates module dependency graphs with circular dependency identification, coupling metrics calculation, and visualization output in Graphviz or D3 formats.

## Capabilities

- Generate module dependency graphs
- Identify circular dependencies
- Calculate coupling metrics (afferent, efferent)
- Calculate instability metrics
- Visualize dependencies (Graphviz, D3)
- Package/module level analysis
- External dependency tracking

## Target Processes

- microservices-decomposition
- refactoring-plan
- migration-strategy

  "required": ["entryPoints"],
  "properties": {
    "entryPoints": {
      "type": "array",
      "items": { "type": "string" },
      "description": "Entry point files or directories"
    },
    "outputFormat": {
      "type": "string",
      "enum": ["dot", "json", "d3", "mermaid"],
      "default": "dot"
    },

## Usage Example

```javascript
{
  kind: 'skill',
  skill: {
    name: 'dependency-graph-generator',
    context: {
      entryPoints: ['src/index.ts'],
      outputFormat: 'dot',
      outputPath: 'docs/dependencies.dot',
      options: {
        groupByPackage: true,
        detectCircular: true
      }
    }
  }
}
```
