design-review

design-review is a skill for Claude Code from RamonBedin/mcp-game-deck. It costs 23 tokens per session (348 once invoked), scanned A, original, MIT.

A review of a game design document for missing details, contradictions, technical feasibility, and balance concerns. Unity 6 and URP are tools for building and rendering games.

In plain words
What is it for?
Use it to check mechanics, formulas, dependencies, tuning settings, acceptance criteria, and whether the design fits a Unity 6 project using URP.
Why use it?
It finds unclear rules, missing edge cases, incorrect numbers, and implementation risks before development begins.

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 11d 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.

What it actually says

When this skill is invoked:

  1. Read the design document in full.

  2. Check completeness (all sections present):

    • Overview / summary
    • Player experience goal
    • Detailed mechanics/rules
    • Formulas (if numeric system)
    • Edge cases handled
    • Dependencies on other systems
    • Tuning knobs identified
    • Acceptance criteria
  3. Check consistency:

    • No contradictions within the document
    • Numbers add up (economy flows, damage ranges)
    • References to other systems are accurate
  4. Check implementability with our stack:

    • Can this be built with Unity 6 + URP?
    • Which MCP tools would be needed?
    • ScriptableObject data model feasible?
    • Performance implications clear?
  5. Output:

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.
