/rforge:deps - Dependency Graph

Build and visualize dependency relationships in your R package ecosystem.

What It Does

Uses the rforge_deps MCP tool to:

• Parse DESCRIPTION files
• Build dependency graph
• Identify topological order
• Find circular dependencies
• Calculate dependency depth

Usage

# Dependency graph for ecosystem
/rforge:deps

# Graph for specific package
/rforge:deps medfit

# Include reverse dependencies
/rforge:deps --reverse

Output

Returns dependency analysis with:

• Graph Structure: ASCII or Mermaid diagram
• Topological Order: Safe update sequence
• Depth Levels: How deep each dependency goes
• Circulars: Any circular dependency issues

Examples

Ecosystem Dependencies

🔗 DEPENDENCY GRAPH

Level 0 (Core):
  └─ medfit

Level 1 (Implementations):
  ├─ probmed → medfit
  ├─ medsim → medfit
  └─ sensitivity → medfit

Level 2 (Meta):
  └─ mediationverse → medfit, probmed, medsim

Topological order: medfit → {probmed, medsim, sensitivity} → mediationverse

Reverse Dependencies

🔗 REVERSE DEPS: medfit

Direct dependents: 3
  • probmed (suggests in 2 places)
  • medsim (imports 1 function)
  • sensitivity (depends)

Indirect dependents: 1
  • mediationverse (via probmed, medsim)

Total ecosystem impact: 4 packages

Use When

• Planning version updates
• Understanding ecosystem structure
• Before making breaking changes
• Coordinating multi-package releases
