What this skill does
Task Estimation When to use this skill Sprint Planning: Decide what work to include in the sprint Roadmap creation: Build long-term plans Resource planning: Estimate team size and schedule Instructions Step 1: Story Points (relative estimation) Fibonacci sequence: 1, 2, 3, 5, 8, 13, 21 Step 2: Planning Poker Process: 1. Product Owner explains the story 2. Team asks questions 3. Everyone picks a card (1, 2, 3, 5, 8, 13) 4. Reveal simultaneously 5. Explain highest/lowest scores 6. Re-vote 7. Reach consensus Example: Step 3: T-Shirt Sizing (quick estimation) Step 4: Consider risk and uncertainty Estimation adjustment: Output format Estimation document template Constraints Required rules (MUST) 1. Relative estimation: Relative complexity instead of absolute time 2. Team consensus: Agreement from the whole team, not individuals 3. Use historical data: Plan based on velocity Prohibited (MUST NOT) 1. Pressuring individuals: Estimates are not promises 2. Overly granular estimation: Split anything 13+ points 3. Turning estimates into deadlines: estimate ≠ commitment Best practices 1. Break Down: Split big work into smaller pieces 2. Reference Stories: Reference similar past work 3. Include buffer: Prepare for the unexpected References Scrum Guide Planning Poker Story Points Metadata Version Current version: 1.0.0 Last updated: 2025-01-01 Compatible platforms: Claude, ChatGPT, Gemini Tags #estimation #agile #story-points #planning-poker #sprint-planning #project-management Examples Example 1: Basic usage <!-- Add example content here --> Example 2: Advanced usage <!-- Add advanced example content here -->
