scope-check— agent skill

When this skill is invoked:

1. Read the original plan — Find the relevant document:

• If a feature name: read the design doc from design/gdd/
• If a sprint number: read the sprint plan from production/sprints/
• If a milestone: read the milestone definition from production/milestones/

1. Read the current state — Check what has actually been implemented or is in progress:

• Scan the codebase for files related to the feature/sprint
• Read git log for commits related to this work
• Check for TODO comments that indicate unfinished scope additions

1. Compare original vs current scope:

   ## Scope Check: [Feature/Sprint Name]
   Generated: [Date]

   ### Original Scope
   [List of items from the original plan]

   ### Current Scope
   [List of items currently implemented or in progress]

   ### Scope Additions (not in original plan)
   | Addition | Who Added | When | Justified? | Effort |
   |----------|-----------|------|------------|--------|
   | [item] | [commit/person] | [date] | [Yes/No/Unclear] | [S/M/L] |

   ### Scope Removals (in original but dropped)
   | Removed Item | Reason | Impact |
   |-------------|--------|--------|
   | [item] | [why removed] | [what's affected] |

   ### Bloat Score
   - Original items: [N]
   - Current items: [N]
   - Items added: [N] (+[X]%)
   - Items removed: [N]
   - Net scope change: [+/-N] ([X]%)

   ### Risk Assessment
   - **Schedule Risk**: [Low/Medium/High] — [explanation]
   - **Quality Risk**: [Low/Medium/High] — [explanation]
   - **Integration Risk**: [Low/Medium/High] — [explanation]

   ### Recommendations
   1. **Cut**: [Items that should be removed to stay on schedule]
   2. **Defer**: [Items that can move to a future sprint/version]
   3. **Keep**: [Additions that are genuinely necessary]
   4. **Flag**: [Items that need a decision from producer/creative-director]

1. Output the scope check with a clear verdict:

• On Track: Scope within 10% of original
• Minor Creep: 10-25% scope increase — manageable with adjustments
• Significant Creep: 25-50% scope increase — need to cut or extend timeline
• Out of Control: >50% scope increase — stop and re-plan

Rules

• Scope creep is additions without corresponding cuts or timeline extensions
• Not all additions are bad — some are discovered requirements. But they must be acknowledged and accounted for.
• When recommending cuts, prioritize preserving the core player experience over nice-to-haves
• Always quantify scope changes — "it feels bigger" is not actionable, "+35% items" is
