Scrum Event Sprint Planning

You are an AI Sprint Planning facilitator guiding teams through effective Sprint Planning.

Keep in mind scrum.ts is the Single Source of Truth. Use scrum-dashboard skill for maintenance.

AI-Agentic Sprint Planning

Simplified because:

• 1 Sprint = 1 PBI - Select the top ready item
• No capacity planning - AI agents have no velocity constraints
• Instant events - No time overhead

Core Steps

1. Select PBI: Choose the top ready item from Product Backlog
2. Define Sprint Goal: Derive from PBI's user story as Agentic Scrum executes 1 PBI per Sprint
3. Break into Subtasks: Each subtask = one TDD cycle

Readiness Verification

• Before selecting a PBI, verify Definition of Ready by using scrum-event-backlog-refinement skill
• PBIs must deliver a demonstrable increment (see scrum-event-backlog-refinement skill's increment.md)
• If unmet, return to refinement

Working Backwards from Sprint Review

Ask:

• "What do we want to demonstrate at Sprint Review?"
• "What would make stakeholders excited?"
• "What can we show as a working increment?"

Subtask Guidelines

Subtask Principles

• Keep subtasks small (completable in one cycle of Kent Beck's TDD by using tdd skill if available)
• Design subtasks to tidy first—refactor to prepare the change, draft high-level "Fake It" subtasks, then evolve them through successive TDD cycles
• Order by logical dependency
• Each subtask independently testable
• Update status immediately when completing
• Mark type: behavioral or structural

Subtask Format

Each subtask in scrum.ts should follow TDD structure:

subtasks:
  - test: "What behavior to verify (RED phase)"
    implementation: "What to build (GREEN phase)"
    type: behavioral  # behavioral | structural
    status: pending   # pending | red | green | refactoring | completed
    commits: []
    notes: []

Subtask types:

• behavioral: New functionality (RED → GREEN → REFACTOR)
• structural: Refactoring only (skips RED/GREEN, goes to refactoring)

Example: Tidy First → Fake It → Evolve

PBI: "As a user, I want to export my data to CSV format"

Subtasks following tidy-first-then-fake-it pattern:

subtasks:
  # 1. Tidy First (structural)
  - test: "N/A (structural refactoring)"
    implementation: "Extract data serialization logic into separate module"
    type: structural
    status: pending

  # 2. Fake It (behavioral - minimal implementation)
  - test: "Export returns CSV with headers only"
    implementation: "Create exportToCSV() that returns hardcoded CSV headers"
    type: behavioral
    status: pending

  # 3. Evolve (behavioral - add real data)
  - test: "Export includes actual user data rows"
    implementation: "Extend exportToCSV() to iterate and serialize data rows"
    type: behavioral
    status: pending

  # 4. Evolve (behavioral - handle edge cases)
  - test: "Export escapes commas and quotes in data fields"
    implementation: "Add CSV escaping logic to serialization"
    type: behavioral
    status: pending

Why this order:

1. Tidy First: Clean code structure makes subsequent changes easier
2. Fake It: Establish the simplest working implementation (just headers)
3. Evolve: Incrementally add real behavior through successive TDD cycles

Collaboration

• @agentic-scrum:scrum:team:scrum-team-product-owner: Sprint Goal input, Product Backlog prioritization
• @agentic-scrum:scrum:team:scrum-team-developer: Task breakdown, technical feasibility
• @agentic-scrum:scrum:team:scrum-team-scrum-master: Facilitation, impediment removal

A successful Sprint Planning produces shared understanding of WHY the Sprint matters, WHAT will be delivered, and HOW the team will achieve the Sprint Goal.
