# Scope Check
|
||
|
||
This skill is read-only — it reports findings but writes no files.
|
||
|
||
Compares original planned scope against current state to detect, quantify, and triage
|
||
scope creep.
|
||
|
||
**Argument:** `$ARGUMENTS[0]` — feature name, sprint number, or milestone name.
|
||
|
||
---
|
||
|
||
## Phase 1: Find the Original Plan
|
||
|
||
Locate the baseline scope document for the given argument:
|
||
|
||
- **Feature name** → read `design/gdd/[feature].md` or matching file in `design/`
|
||
- **Sprint number** (e.g., `sprint-3`) → read `production/sprints/sprint-03.md` or similar
|
||
- **Milestone** → read `production/milestones/[name].md`
|
||
|
||
If the document is not found, report the missing file and stop. Do not proceed without
|
||
a baseline to compare against.
|
||
|
||
---
|
||
|
||
## Phase 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 (`git log --oneline --since=[start-date]`)
|
||
- Check for TODO/FIXME comments that indicate unfinished scope additions
|
||
- Check active sprint plan if the feature is mid-sprint
|
||
|
||

|
||
|
||
## Phase 3: Compare Original vs Current Scope
|
||
|
||
Produce the comparison report:
|
||
|
||
```markdown
|
||
## 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 | Source | 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]
|
||
```
|
||

|
||
|
||
## Phase 4: Verdict
|
||
|
||
Assign a canonical verdict based on net scope change:
|
||
|
||
| Net Change | Verdict | Meaning |
|
||
|-----------|---------|---------|
|
||
| ≤10% | **PASS** | On Track — within acceptable variance |
|
||
| 10–25% | **CONCERNS** | Minor Creep — manageable with targeted cuts |
|
||
| 25–50% | **FAIL** | Significant Creep — must cut or formally extend timeline |
|
||
| >50% | **FAIL** | Out of Control — stop, re-plan, escalate to producer |
|
||
|
||
Output the verdict prominently:
|
||
|
||
```
|
||
**Scope Verdict: [PASS / CONCERNS / FAIL]**
|
||
Net change: [+X%] — [On Track / Minor Creep / Significant Creep / Out of Control]
|
||
```
|
||
|
||
---
|
||
|
||
## Phase 5: Next Steps
|
||
|
||
After presenting the report, offer concrete follow-up:
|
||
|
||
- **PASS** → no action required. Suggest re-running before next milestone.
|
||
- **CONCERNS** → offer to identify the 2–3 additions with best cut ratio. Reference `/sprint-plan update` to formally re-scope.
|
||
- **FAIL** → recommend escalating to producer. Reference `/sprint-plan update` for re-planning or `/estimate` to re-baseline timeline.
|
||
|
||
Always end with:
|
||
> "Run `/scope-check [name]` again after cuts are made to verify the verdict improves."
|

||
### 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
