name	sprint-planner
description	Facilitate sprint planning, effort estimation, capacity planning, and backlog grooming. Use this skill whenever someone asks about sprint planning, story points, effort estimation, or says things like "plan the sprint", "estimate this work", "story points", "capacity planning", "backlog grooming", "prioritize the backlog", "what fits in this sprint", "velocity", or "sprint retrospective". Also trigger when someone mentions iteration planning, work breakdown, or release planning.

Sprint Planner

Facilitate sprint planning ceremonies, effort estimation, capacity planning, and backlog management for the development team.

Sprint Planning Protocol

Step 1: Review Previous Sprint

Before planning the next sprint, review:

1. Velocity: Average story points completed over last 3 sprints.
2. Carryover: Unfinished stories from the previous sprint (why weren't they completed?).
3. Retrospective actions: Are action items from the last retro being addressed?

## Previous Sprint Summary
- **Sprint**: [Sprint Name/Number]
- **Committed**: [X] story points
- **Completed**: [Y] story points
- **Velocity trend**: [improving | stable | declining]
- **Carryover stories**: [list]
- **Blockers encountered**: [list]

Step 2: Capacity Planning

Calculate team capacity for the upcoming sprint:

## Team Capacity
| Team Member | Available Days | Capacity Factor | Effective Days |
|-------------|---------------|-----------------|----------------|
| [Name] | [X] / [Sprint Length] | [0.0-1.0] | [Result] |

**Total team capacity**: [Sum] effective days
**Capacity factor adjustments**: Holidays, PTO, on-call duty, meetings, tech debt allocation
**Recommended commitment**: [70-80%] of theoretical capacity

Capacity Factor Guide

• 1.0: Fully available, no meetings or other obligations
• 0.8: Standard (daily standups, sprint ceremonies, some meetings)
• 0.6: Heavy meeting load, mentoring responsibilities
• 0.4: On-call primary, significant non-sprint work
• 0.0: On leave, unavailable

Step 3: Backlog Grooming

Ensure stories are ready for sprint planning:

Story Readiness Checklist (Definition of Ready)

• User story follows format: "As a [role], I want [capability] so that [benefit]"
• Acceptance criteria are clear, testable, and complete
• Dependencies identified and resolved (or tracked)
• UI mockups/designs attached (for frontend stories)
• API contract defined (for backend stories)
• Data model changes identified
• Estimated by the team (story points assigned)
• Story fits within a single sprint (if not, split it)

Story Template

## [TICKET-ID]: [Story Title]

**As a** [user role]
**I want** [capability]
**So that** [business value]

### Acceptance Criteria
- [ ] Given [context], when [action], then [expected result]
- [ ] Given [context], when [action], then [expected result]

### Technical Notes
- Backend: [API endpoints, service objects, migrations needed]
- Mobile: [Screens, hooks, components needed]
- Infrastructure: [Terraform changes, config updates]

### Dependencies
- Blocked by: [TICKET-ID] (if any)
- Blocks: [TICKET-ID] (if any)

### Estimate
- Story Points: [1 | 2 | 3 | 5 | 8 | 13]
- T-Shirt Size: [S | M | L | XL]

Step 4: Effort Estimation

Use modified Fibonacci story points (1, 2, 3, 5, 8, 13, 21):

Story Point Reference

Points are relative size, not time. The column that used to sit here — a "Duration Guide" mapping 5 points to "1-2 days" — is the classic way to destroy the abstraction, and it contradicted the first estimation guideline below ("Compare, don't calculate") on the same screen.

Two reasons it has to go, and the second is the one that bites:

1. A 5 is not 1-2 days for whom? A team of seniors on a familiar codebase and a team onboarding deliver very different hours for the same relative size. That is not noise to be corrected — it is the whole reason points exist rather than hours.
2. It makes velocity circular. This skill measures velocity (Step 1, and Velocity Tracking below) precisely to discover what a point is worth for this team, empirically, over time. If the table has already declared that a 5 is 1-2 days, velocity can only measure how wrong the table is. You cannot fix a conversion rate a priori and also claim to be measuring it.

Time comes out of velocity, not out of a table. Estimate relative size; let the team's own completed-points-per-sprint convert it to a date.

Points	Relative size	Example
1	Trivial — the reference story everyone agrees on, or smaller	Config change, copy update, simple bug fix
2	Small	Single endpoint CRUD, simple UI component
3	Medium-small	Endpoint with business logic, form with validation
5	Medium	Feature with multiple endpoints, complex UI flow
8	Large	Multi-component feature, data migration, integration
13	Very large — usually a sign the story wants splitting	Cross-cutting feature, architectural change
21	Too large to plan	Must be broken down further — do not commit it

The examples are the useful part: they are anchors, not definitions. Pick the row whose example your story feels closest to in effort, and move on — an estimate argued to consensus for twenty minutes is not more accurate than the first one, it is just more expensive.

Estimation Guidelines

• The team estimates, not the planner and not this skill. You can facilitate — surface the anchors, ask what makes a story bigger than the reference, flag when an estimate implies a hidden dependency. You cannot supply the number: it encodes what the team knows about a codebase and about itself, and neither is in the ticket. An estimate produced by reading a ticket is a guess wearing a Fibonacci number.
• Compare, don't calculate: Estimate relative to a reference story the team agrees on.
• Include everything: Development, testing, code review, deployment verification.
• Uncertainty adds points: If unclear, round up. Uncertainty = risk.
• 21+ means split: Any story estimated at 21 or above must be decomposed.
• Spike stories: Timeboxed research tasks. Always 3 or 5 points. Output is knowledge, not code.

Step 5: Sprint Commitment

Sprint Backlog Template

## Sprint [Number]: [Sprint Goal]
**Start**: YYYY-MM-DD | **End**: YYYY-MM-DD | **Duration**: [X] days

### Sprint Goal
[One sentence describing the sprint's primary objective]

### Committed Stories
| Priority | Ticket | Title | Points | Assignee | Status |
|----------|--------|-------|--------|----------|--------|
| P0 | PROJ-101 | [Critical story] | 5 | [Name] | To Do |
| P1 | PROJ-102 | [High priority] | 3 | [Name] | To Do |
| P2 | PROJ-103 | [Normal priority] | 8 | [Name] | To Do |

### Totals
- **Committed**: [X] story points
- **Team velocity (avg)**: [Y] story points
- **Commitment ratio**: [X/Y * 100]% (target: 80-100%)

### Risks and Dependencies
| Risk | Impact | Mitigation |
|------|--------|------------|

### Tech Debt Allocation
[10-20% of capacity reserved for tech debt, refactoring, and tooling improvements]

Commitment Guidelines

• Never exceed velocity by more than 10% unless the team explicitly agrees.
• Reserve 10-20% of capacity for tech debt, bugs, and operational work.
• Prioritize by value: P0 (must have) → P1 (should have) → P2 (nice to have).
• Respect dependencies: Do not commit to blocked stories without a resolution plan.
• One sprint goal: The team should be able to state the sprint's purpose in one sentence.

Spike Stories

For uncertain or exploratory work, use timeboxed spike stories:

## Spike: [Investigation Topic]

### Question to Answer
[What specific question or uncertainty are we resolving?]

### Timebox
[X] hours / [Y] story points (max 5 points)

### Expected Output
- [ ] Written summary of findings
- [ ] Recommendation with pros/cons
- [ ] Refined story estimates for the actual implementation
- [ ] Proof of concept (if applicable)

### Acceptance Criteria
- [ ] Question is answered with enough confidence to estimate implementation
- [ ] Findings are documented in [location]

| Sprint N | [X] | [Y] | [Z] | |
