Hybrid Ralph - Show Dependencies

You are displaying the dependency graph and analysis for all stories in the PRD.

Path Storage Modes

PRD file location depends on the storage mode:

• New Mode: ~/.plan-cascade/<project-id>/prd.json or in worktree directory
• Legacy Mode: prd.json in project root or worktree

Step 1: Verify PRD Exists

# Get PRD path from PathResolver
PRD_PATH=$(uv run python -c "from plan_cascade.state.path_resolver import PathResolver; from pathlib import Path; print(PathResolver(Path.cwd()).get_prd_path())" 2>/dev/null || echo "prd.json")

# Also check local prd.json (in worktree)
if [ -f "prd.json" ]; then
    PRD_PATH="prd.json"
elif [ ! -f "$PRD_PATH" ]; then
    echo "ERROR: No PRD found at: $PRD_PATH"
    exit 1
fi

Step 2: Read PRD

Read the PRD file at $PRD_PATH to get all stories and their dependencies.

Step 3: Build Dependency Graph

Create a mapping of:

• Story → Dependencies (what this story depends on)
• Story → Dependents (what depends on this story)
• Story → Depth (how many levels from root)

Step 4: Detect Issues

Check for Circular Dependencies

Use depth-first search to detect cycles:

For each story:
  Mark as visiting
  For each dependency:
    If dependency is visiting → CYCLE DETECTED
    If dependency not visited → recurse
  Mark as visited

Check for Orphan Stories

Find stories with:

• No dependencies
• No dependents

Check for Bottlenecks

Find stories with many dependents (threshold: 4+).

Step 5: Display Dependency Report

## Visual Graph

{ASCII tree showing dependencies}

Example:
story-001 (Database Schema)
    │
    ├─── story-002 (User Registration)
    │        │
    │        └─── story-004 (Password Reset)
    │
    └─── story-003 (User Login)
             │
             └─── story-004 (Password Reset)

## Dependency Details

{For each story, show:
  - ID and title
  - Dependencies (if any)
  - Depth level
  - Dependents (if any)
  - Type (root, intermediate, endpoint, orphan, bottleneck)
}

## Analysis

- Maximum depth: {depth} levels
- Critical path length: {count} stories
- Bottleneck stories: {list}
- Circular dependencies: {count or "none detected"}
- Orphan stories: {count or "none detected"}
