Bulk Prototype Review
Review every registered prototype for completeness, quality, and cross-prototype consistency.
Steps
1. Gather All Prototypes
- Read the prototypes index at
scaffold/prototypes/_index.md.
- Read every prototype file in
scaffold/prototypes/ (Glob scaffold/prototypes/PROTO-*.md).
- Read the design doc at
scaffold/design/design-doc.md.
- Read all system designs — Glob
scaffold/design/systems/SYS-*.md.
- Read all engine docs from
scaffold/engine/.
- Read all ADRs — Glob
scaffold/decisions/ADR-*.md.
- Read known issues at
scaffold/decisions/known-issues.md.
- Read design debt at
scaffold/decisions/design-debt.md.
- If no prototypes exist, report that and stop.
2. Per-Prototype Completeness
For each prototype, check pre-spike sections (all prototypes) and post-spike sections (Complete prototypes only):
Pre-Spike:
| Section | What "Complete" Means |
|---|
| Question | ONE specific, answerable question |
| Hypothesis | Expected answer with reasoning |
| Scope: Build | Numbered list of minimum steps |
| Scope: Skip | At least 2 explicit exclusions |
| Approach | Numbered execution steps |
| Related Documents | At least 1 valid scaffold doc reference |
Post-Spike (if Status is Complete):
| Section | What "Complete" Means |
|---|
| Answer | Direct answer to the Question |
| Evidence | Specific measurements or observations |
| Surprises | Findings listed or explicitly "None" |
| Design Impact | Table of affected docs with changes |
| ADRs Filed | Every Design Impact has a corresponding ADR |
| Disposition | Discarded / Archived / Absorbed with reason |
3. Per-Prototype Quality
For each prototype, check:
- Question is specific and singular — not compound or vague.
- Scope is minimal — Build scope is the minimum to answer the question.
- Skip boundaries are explicit — clear discipline boundary.
- Right-sized — achievable in one spike session.
4. Cross-Prototype Consistency
This is unique to bulk review — check relationships BETWEEN prototypes:
- Question overlap. Flag prototypes with substantially similar questions. Suggest merging or clarifying the distinction.
- Scope overlap. Flag prototypes with overlapping Build scopes — they may be doing redundant work.
- Coverage gaps. Cross-reference with systems, engine docs, slices, and known issues. Flag areas of significant uncertainty that have no prototype.
- ADR follow-through. For Complete prototypes: verify every Design Impact entry has a filed ADR. Flag missing ADRs.
- Disposition consistency. Flag Absorbed prototypes without a referenced TASK-###. Flag prototypes marked Complete but with empty post-spike sections.
- Stale prototypes. Flag Draft prototypes that reference documents which have since changed significantly or been deprecated.
- Status consistency. Check that index status matches file status for every prototype.
5. Registration Check
- Every prototype in
scaffold/prototypes/_index.md must have a corresponding file.
- Every prototype file must be registered in
scaffold/prototypes/_index.md.
- IDs, names, statuses, and dispositions must match between files and index.
Output Format
## Bulk Prototype Review — X prototypes audited
### Overview
| ID | Name | Status | Pre-Spike | Post-Spike | Quality Issues | ADRs |
|----|------|--------|-----------|------------|----------------|------|
| PROTO-001 | ... | Draft | 5/6 | — | 1 issue | — |
| PROTO-002 | ... | Complete | 6/6 | 5/6 | 0 issues | 2 |
### Per-Prototype Details
#### PROTO-001 — [Name]
| Section | Status | Notes |
|---------|--------|-------|
| ... | ... | ... |
Quality Issues:
- [specific issues with quotes]
(repeat for each prototype)
### Cross-Prototype Consistency
- **Question overlap:** [OK / overlapping prototypes found]
- **Scope overlap:** [OK / redundant Build scopes found]
- **Coverage gaps:** [OK / areas without prototypes]
- **ADR follow-through:** [OK / X missing ADRs]
- **Disposition consistency:** [OK / issues found]
- **Stale prototypes:** [OK / X stale prototypes]
### Registration
[Any mismatches between index and files]
### Recommendations (prioritized)
1. [Most impactful fix across all prototypes]
2. [Second priority]
3. ...
Rules
- This skill is read-only. Do not modify any files.
- Cross-prototype checks are the main value of bulk review over individual
/scaffold-review-prototype calls. Emphasize relationship issues.
- Be specific. Quote problematic text when flagging issues.
- Coverage gaps are high-value findings. Identifying what SHOULD be prototyped but isn't is as important as auditing existing prototypes.
- If all prototypes are well-written, say so. Don't manufacture issues.
- Prioritize recommendations by blast radius — issues that affect multiple prototypes or the pipeline rank higher.
