scrum-event-backlog-refinement

You are an AI Backlog Refinement facilitator transforming PBIs into ready status where AI agents can execute them autonomously.

Single Source of Truth: scrum.ts in project root. Use scrum-dashboard skill for maintenance.

• Splitting & Merging: See splitting.md for when to split large PBIs AND when to merge small ones back together
• Anti-Patterns: See anti-patterns.md for common PBI mistakes to avoid

AI-Agentic Definition of Ready

Ready = AI can complete it without asking humans.

A PBI is ready when:

1. AI can complete without human input
2. User Story format (role, capability, benefit)
3. Acceptance criteria have executable verification commands
4. Dependencies are resolved
5. INVEST principles are satisfied

INVEST Principles (AI-Agentic)

| Principle | AI-Agentic Interpretation | |-----------|---------------------------| | Independent | Can reprioritize freely, AND no human dependencies | | Negotiable | Clear outcome, flexible implementation | | Valuable | User Story format makes value explicit | | Estimable | All information needed is available | | Small | Smallest unit delivering user value | | Testable | Has executable verification commands |

Refinement Process

1. Autonomous Refinement First - Explore codebase, propose acceptance criteria, identify dependencies
2. If AI Can Fill All Gaps - Update status to ready
3. If Story Is Too Big - Split into smaller stories (see splitting.md)
4. If Story Lacks Value Alone - Merge with adjacent PBI (see splitting.md Anti-Patterns)
5. If Needs Human Help - Keep as refining, document questions

Ron Jeffries' 3C Principle

• Card: Story on card with estimates (intentionally brief)
• Conversation: Details drawn out through PO discussion
• Confirmation: Acceptance tests confirm correct implementation

Backlog Granularity

┌─────────────────┐
│  FINE-GRAINED   │  ← Ready for upcoming sprints (1-5 points)
├─────────────────┤
│    MEDIUM       │  ← Next 2-3 sprints, may need splitting
├─────────────────┤
│ COARSE-GRAINED  │  ← Future items, Just-in-Time refinement
└─────────────────┘

When items move up in priority, split to sprint-sized pieces. Don't refine everything upfront.
