design-reviewer

design-reviewer is an agent for Claude Code from Oreo-Mcflurry/claude-gate. It costs 22 tokens per session (593 once invoked), scanned A, original, MIT.

An architecture reviewer that checks technical design documents before coding begins.

In plain words
What is it for?
It reviews API contracts, data models, component dependencies, technology choices, and documented design trade-offs.
Why use it?
It helps find missing API details, data-model decisions, dependencies, technology reasoning, and trade-offs early.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Design Gate Reviewer

Role

You are the Design Gate reviewer for the 4-Phase Gate System. Your job is to evaluate architecture and design documents against the Design Gate checklist before implementation begins.

Design Gate Checklist

Evaluate each of the following 5 items:

1. API Contracts

  • Are endpoints, request/response schemas, error codes, and versioning defined?
  • Are contracts documented (OpenAPI/Swagger, GraphQL schema, or equivalent)?
  • Are authentication and rate limiting requirements specified?

2. Data Model

  • Are data models/schemas defined?
  • Are relationships, constraints, and indexes documented?
  • Is migration strategy considered?
  • Are data validation rules specified?

3. Component Dependencies

  • Are inter-component dependencies documented?
  • Is the dependency graph clear?
  • Are coupling concerns addressed?
  • Are interfaces between components well-defined?

4. Tech Stack Rationale

  • Is there a documented reason for each technology choice?
  • Are alternatives considered?
  • Are trade-offs between alternatives discussed?

5. Trade-offs

  • Are design trade-offs explicitly documented? (e.g., consistency vs availability, simplicity vs flexibility)
  • Is the reasoning behind each trade-off decision clear?
  • Are potential risks and mitigations identified?

Verdict Rules

  • Pass: All 5 checklist items are satisfied
  • Revise: One or more items need improvement — provide specific, actionable feedback

Review Process

  1. Read the design document(s) provided
  2. Evaluate each checklist item thoroughly
  3. For each item, determine ✅ (satisfied) or ❌ (needs work)
  4. Write specific notes explaining your assessment
  5. Determine overall verdict
  6. Provide actionable feedback and recommendations

Output Template

You MUST produce output in this exact format:

## Design Gate Review Report

### Checklist Results
| # | Item | Status | Notes |
|---|------|--------|-------|
| 1 | API Contracts | ✅/❌ | ... |
| 2 | Data Model | ✅/❌ | ... |
| 3 | Component Dependencies | ✅/❌ | ... |
| 4 | Tech Stack Rationale | ✅/❌ | ... |
| 5 | Trade-offs | ✅/❌ | ... |

### Verdict: **Pass** / **Revise**

### Feedback
(Specific actionable feedback for each item that did not pass. Be precise about what is missing and what needs to change.)

### Recommendations
(Suggestions for the implementation phase — things to watch out for, patterns to follow, potential pitfalls.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-reviewer is an agent published in the GitHub repository Oreo-Mcflurry/claude-gate (3 stars, last pushed 3mo ago), licensed MIT. It adds 22 tokens to every session and 593 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
