design-review

design-review is a skill for Claude Code from IdoCohen560/claude-unity-game-studio. It costs 34 tokens per session (3,047 once invoked), scanned A, a copy of design-review, MIT.

A review process for checking whether a game design document is complete, consistent, practical to build, and aligned with the project’s design standards. A game design document describes how the game and its systems should work.

In plain words
What is it for?
Use it before handing a game design document to programmers, especially when checking its requirements, dependencies, and readiness for technical work.
Why use it?
Design problems found after programming starts are slower and more expensive to fix. The review exposes missing details, contradictions, broken dependencies, and ideas that cannot yet be implemented clearly.

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-review 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.

How it starts

The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phase 0: Parse Arguments

Extract --depth [full|lean|solo] if present. Default is full when no flag is given.

Note: --depth controls the analysis depth of this skill (how many specialist agents are spawned). It is independent of the global review mode in production/review-mode.txt, which controls director gate spawning. These are two different concepts — --depth is about how thoroughly this skill analyses the document.

  • full: Complete review — all phases + specialist agent delegation (Phase 3b)
  • lean: All phases, no specialist agents — faster, single-session analysis
  • solo: Phases 1-4 only, no delegation, no Phase 5 next-step prompt — use when called from within another skill

Phase 1: Load Documents

Read the target design document in full. Read CLAUDE.md to understand project context and standards. Read related design documents referenced or implied by the target doc (check design/gdd/ for related systems).

Dependency graph validation: For every system listed in the Dependencies section, use Glob to check whether its GDD file exists in design/gdd/. Flag any that don't exist yet — these are broken references that downstream authors will hit.

Lore/narrative alignment: If design/gdd/game-concept.md or any file in design/narrative/ exists, read it. Note any mechanical choices in this GDD that contradict established world rules, tone, or design pillars. Pass this context to game-designer in Phase 3b.

Prior review check: Check whether design/gdd/reviews/[doc-name]-review-log.md exists. If it does, read the most recent entry — note what verdict was given and what blocking items were listed. This session is a re-review; track whether prior items were addressed.


Phase 2: Completeness Check

Evaluate against the Design Document Standard checklist:

  • Has Overview section (one-paragraph summary)
  • Has Player Fantasy section (intended feeling)
  • Has Detailed Rules section (unambiguous mechanics)
  • Has Formulas section (all math defined with variables)
  • Has Edge Cases section (unusual situations handled)
  • Has Dependencies section (other systems listed)
  • Has Tuning Knobs section (configurable values identified)
  • Has Acceptance Criteria section (testable success conditions)

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.
