Plan Dependency Graph

Plan Dependency Graph Skill

Analyze all active plans to build a dependency graph, identify the critical path, and detect stale or blocked plans.

Trigger Conditions

• New plan is created
• Existing plan todos are updated
• Milestone event occurs
• User invokes with "plan triage" or "plan-dependency-graph"

Input Contract

• Required: Path to plans directory (.cursor/plans/)
• Optional: Specific plan to analyze

Output Contract

• Complete plan inventory with status summary
• Dependency graph (which plans/todos block others)
• Critical path identification
• Stale plan detection (no updates > 7 days)
• Archive candidates (all todos completed)
• Blocked plan identification (dependencies unresolved)
• Parallel work opportunities (independent plans that can execute simultaneously)

Tool Permissions

• Read: All plan files in .cursor/plans/
• Write: Plan status updates, archive operations
• Search: Grep for plan references, todo statuses

Execution Steps

1. Inventory plans: Scan .cursor/plans/ for all .plan.md files (excluding archive)
2. Parse status: For each plan, extract todos with their statuses
3. Detect dependencies: Find cross-plan references (one plan's todo depends on another plan)
4. Build graph: Create dependency graph of plans and their todos
5. Find critical path: Identify the longest chain of blocking dependencies
6. Detect staleness: Flag plans with no todo updates in 7+ days
7. Identify completions: Plans with all todos completed are archive candidates
8. Report: Produce triage report with actionable recommendations

Plan Health Scores

• Healthy: Active progress, no stale todos, no blockers
• Stale: No updates in 7+ days
• Blocked: Has pending todos with unresolved dependencies
• Complete: All todos done — candidate for archival
• Abandoned: No updates in 30+ days with pending todos
