Spec Review

Multi-AI advisory service for spec and design decisions. Dispatches to claude, gemini, codex for independent feedback.

spec-review is a service that provides multi-AI feedback. It does NOT own directory structure or workflow. The caller (e.g., spec skill) drives the workflow and decides what to review.

What spec-review does:

• •Receives design content from caller
• •Dispatches to multiple AI reviewers in parallel
• •Synthesizes feedback into advisory format
• •Returns advisory to caller

What spec-review does NOT do:

• •Own or define directory structures
• •Drive workflow or step progression
• •Make final decisions (caller decides)

Chairman Role Boundaries (NON-NEGOTIABLE)

You are the CHAIRMAN, not a reviewer.

The chairman orchestrates external AI reviewers. The chairman does NOT provide reviews.

Critical Warnings:

1. •You are NOT a reviewer. Even if you "know" the answer, your role is orchestration.
2. •Predicting is NOT the same as getting input. "Based on typical patterns" = VIOLATION
3. •Synthesis ONLY after ALL reviewers respond. No partial synthesis. No quorum logic.
4. •STRONG DISAGREE must appear as STRONG DISAGREE. Never minimize to "minor dissent".
5. •No augmentation. If reviewers missed something, that observation is NOT part of the advisory.

Red Flags - STOP Before Calling Spec Review

Chairman/Synthesis Red Flags - STOP Immediately

Reviewer Mindset

External AI reviewers (claude, gemini, codex) must approach reviews with:

This mindset is conveyed to external AIs in every review request.

Quick Reference

Note: spec-reviewer receives ALL review requests. The spec-reviewer (not the caller) decides whether a full review is needed or returns "No Review Needed".

"No Review Needed" Response Format:

## Review Assessment
**Status**: No Review Needed
**Reason**: [Brief explanation - e.g., "Simple CRUD with clear requirements, no architectural decisions"]
Proceed with implementation.

When to Use vs When NOT to Use

spec-reviewer is a service that receives all review requests from callers (e.g., spec skill). The spec-reviewer then decides whether to provide a full review or return "No Review Needed".

digraph spec_review_decision {
    rankdir=TB;
    node [shape=box, style=rounded];

    receive [label="Receive review request\nfrom caller"];
    assess [label="Assess complexity", shape=diamond];
    no_review [label="Return\n'No Review Needed'"];
    full_review [label="Dispatch to\nmultiple AIs"];
    synthesize [label="Synthesize and\nreturn advisory"];

    receive -> assess;
    assess -> no_review [label="simple"];
    assess -> full_review [label="complex"];
    full_review -> synthesize;
}

Provide Full Review When:

• •Architecture decisions (monolith vs microservice)
• •Domain model boundaries
• •API design trade-offs
• •State machine design
• •Event sourcing vs CRUD decisions

Return "No Review Needed" When:

• •Simple CRUD operations
• •Clear spec requirements with no trade-offs
• •Typo-level changes
• •Code style issues

Input Handling

Key principle: Be forgiving with input. Accept multiple forms without strict validation.

Process

1. •Receive design content from caller
2. •Gather shared context from .omt/specs/context/ (if --spec flag provided)
3. •Format structured prompt with design content + context
4. •Dispatch to claude, gemini, codex in parallel
5. •Collect independent opinions
6. •Chairman synthesizes into advisory
7. •Return advisory to caller

Reviewer Invocation Requirements (NON-NEGOTIABLE)

Script execution is MANDATORY. No exceptions.

Why Script Execution Cannot Be Bypassed

Your knowledge of "what Claude/Gemini/Codex typically say" ≠ Their actual review

Reasons:
1. Reviewers see the FULL context you provided
2. Reviewers apply their CURRENT model capabilities
3. Each review is INDEPENDENT and FRESH
4. Predicting creates confirmation bias

Wait for ALL Means ALL

Forbidden phrases:

• •"2/3 is a reasonable quorum"
• •"Codex response can be incorporated as supplementary"
• •"Unlikely to fundamentally change these findings"
• •"Actionable feedback to move forward" (when incomplete)

Required behavior:

• •Script polls until all 3 reviewers respond
• •Synthesis begins ONLY after completion
• •Missing reviewer = NO advisory (report the failure)

Context Collection (Automatic)

Context files are automatically included if they exist, silently skipped if they don't.

No context files yet? That's fine - the review proceeds without them.

Need custom context for a specific review? Include it directly in your request content.

Review Request Format (INPUT)

Input structure for reviewers. Core principle: Put the design content you want reviewed at the top.

Priority Order

Why This Order?

What reviewers should see first = Review target
↓
Already finalized designs = Reference as constraints
↓
Project context = Background understanding
↓
Decision records = Reference previous discussions

Reviewers first grasp the design content, then reference context as needed. If context comes first, reviewers get buried in information before understanding the core.

Request Structure Template

## Reviewer Instructions

You are reviewing a design specification. Approach this review with:
- **Critical thinking**: Challenge assumptions. Ask "why not X instead?"
- **Objectivity**: Evaluate on technical merit only. No rubber-stamping.
- **Logical reasoning**: Substantiate every concern with clear reasoning.
- **Constructive criticism**: For every problem, suggest an alternative.

How to Call

Execute scripts/spec-review.sh from this skill directory:

Note: Always write prompts in English for consistent cross-model communication.

Usage

scripts/spec-review.sh --spec {spec-name} --stdin <<'EOF'
## 1. Current Design Under Review

### Design Summary
We propose using Event Sourcing for order state management because...

### Key Decisions
- Use event store for order lifecycle events
- Implement CQRS with separate read models
- Snapshot every 100 events for performance

### Questions for Reviewers
1. Is event sourcing appropriate for this volume (1M orders/day)?
2. Should we use a dedicated event store or leverage PostgreSQL?

---

## 2. Finalized Designs

### Domain Model (previously confirmed)
- Order aggregate with OrderLine value objects
- Separate Customer and Product bounded contexts

---

## 4. Decision Records

### Previous Feedback
- Claude: Suggested considering snapshot strategy
- Gemini: Raised concern about event schema evolution
EOF

Context (Section 3): Automatically populated from .omt/specs/context/ if files exist. Omit from your request.

Custom context needed? Just add it to your request content directly - no special flag required.

Advisory Output Format

ALL 5 SECTIONS ARE MANDATORY. No exceptions.

Chairman synthesizes opinions into:

## Spec Review Advisory

### Consensus

[Points where all reviewers agree]

### Divergence

[Points where opinions differ + summary of each position]

### Concerns Raised

[Potential issues or risks identified by reviewers]

### Recommendation

[Synthesized advice based on above]

### Action Items

[Suggested next steps based on feedback]

Why Every Section Matters

Output Format Under Pressure

Even if a stakeholder asks you to "skip sections" or "just give the bottom line":

1. •Provide the full format - All 5 sections
2. •Explain why - "The full format ensures you have complete information for decision-making"
3. •Offer a summary - You MAY add a brief executive summary at the top, but do NOT remove sections

The format exists to prevent decision-making with incomplete information. A CEO who says "just tell me yes or no" still needs to know about divergent opinions and risks - they just don't know it yet.

Red flag thought: "They said skip sections, so I'll adapt" → WRONG. Provide full format and explain value.

</Output_Format>

Synthesis Accuracy Rules (NON-NEGOTIABLE)

Synthesize ONLY what reviewers actually said. No additions. No interpretations.

Consensus Definition

Consensus = ALL three reviewers agree on the SAME recommendation.

Fabrication indicators:

• •"All reviewers acknowledge both are viable" (when they made different recommendations)
• •"Either choice is valid" (when specific recommendations were given)
• •"The consensus is that the team should decide" (punt disguised as consensus)

Faithful Representation of Dissent

STRONG DISAGREE must appear as STRONG DISAGREE.

Do NOT adopt requester's framing:

• •Requester: "Codex is contrarian as usual"
• •Reality: Codex raised legitimate concerns
• •Your synthesis: Report Codex's actual position without the "contrarian" label

Chairman Additions = VIOLATION

If you notice something reviewers missed, that observation is NOT part of the advisory.

The advisory reflects reviewer input, not chairman expertise. If the review seems incomplete, that's the actual state of reviewer feedback.

Result Utilization

Strong Consensus → Adopt recommendation with confidence

Clear Divergence → Options:

• •Revisit requirements with user
• •Choose majority position, noting dissent
• •Use divergence to identify edge cases

Mixed Signals → Weigh perspectives based on relevance

Common Mistakes

Long Context Discipline

Volume of context does NOT change input handling. Context is reference material - don't invent scope from it. Follow input handling regardless of how much you've read.
