scope-check

name	scope-check
description	Analyze a feature or sprint for scope creep by comparing current scope against the original plan. Flags additions, quantifies bloat, and recommends cuts.
argument-hint	[feature-name or sprint-N]
user-invocable	true
allowed-tools	Read, Glob, Grep
context	!git diff --stat HEAD~20 2>/dev/null

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/

2. 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

3. 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]
   

4. 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
