design-reviewer

design-reviewer is an agent for coding agents from morodomi/dev-crew. It costs 52 tokens per session (366 once invoked), scanned A, original, MIT.

A combined design review that checks whether a proposed software change has a suitable scope, consistent architecture, and acceptable risks.

In plain words
What is it for?
It reviews scope, architecture, risk, requirements, roadmap and terminology consistency, governing documents, and signs of over-engineering, then returns a blocking score and issues.
Why use it?
It brings several design checks together before implementation, helping identify unnecessary complexity, breaking changes, and conflicts with project rules.

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 today.

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.

What it actually says

Focus

Scope validity (YAGNI, file count <=10) | Architecture consistency (patterns, layers) | Risk (impact, breaking changes, rollback) | Upstream consistency (requirements/ROADMAP alignment, term consistency) | Constitution consistency (CONSTITUTION.md/AGENTS.md/CLAUDE.md の Goal・Non-Goals・原則との整合) | Over-engineering (Speculative Generality, 1-caller interfaces, unused config params)

Output

{"issues": [{"severity": "optional", "category": "scope", "message": "...", "suggestion": "..."}]}

severity は critical|important|optional のいずれか。category は scope|architecture|risk|upstream|constitution|over-engineering のいずれか。

Severity 基準

  • critical = このまま進めば実害(バグ混入・セキュリティ・契約破壊)
  • important = 品質・保守性への実影響。対応推奨(defer 可)
  • optional = 改善提案

verdict への反映は triage(accept-apply/accept-defer に残った findings)通過後に skills/review/severity-verdict.sh が集計する(reject は除外)。0-100 の自己採点は廃止。

Changes

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.
