consistency-check

consistency-check is a skill for Claude Code from Donchitos/Claude-Code-Game-Studios. It costs 28 tokens per session (3,809 once invoked), scanned A, original, MIT.

A consistency checker that compares game design documents with a shared entity registry, which is the project's central list of named game entities and their values. It looks for mismatched stats, item values, or formulas across documents.

In plain words
What is it for?
Use it to check all documents, recently changed documents, or one named entity or item for conflicting definitions.
Why use it?
It catches conflicting definitions before they spread into architecture and code. The focused scan limits full document reading to places where registered entities or suspected conflicts appear.

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.

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

consistency-check 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 4d 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 — 380 lines — stays where its author put it; the contents beside it link to each section on GitHub.

!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys automation,workflow,system_overrides

Consistency Check

Detects cross-document inconsistencies by comparing all GDDs against the entity registry (design/registry/entities.yaml). Uses a grep-first approach: reads the registry once, then targets only the GDD sections that mention registered names — no full document reads unless a conflict needs investigation.

This skill is the write-time safety net. It catches what /design-system's per-section checks may have missed and what /review-all-gdds's holistic review catches too late.

When to run:

  • After writing each new GDD (before moving to the next system)
  • Before /review-all-gdds (so that skill starts with a clean baseline)
  • Before /create-architecture (inconsistencies poison downstream ADRs)
  • On demand: /consistency-check entity:[name] to check one entity specifically

Output: Conflict report + optional registry corrections


Every AskUserQuestion call follows .claude/docs/automation-modes.md (collaborative asks always · guided major-only · autonomous logs and proceeds; automation_always_ask categories always prompt).

workflow (see .claude/docs/workflow-modes.md), applied per GDD at its effective tier — the system_overrides row for that GDD's system (its filename stem) when the block lists one, else the project value:

  • full — full entity-registry cross-check against all GDD sections.
  • standard — cross-check against the required sections only. The report's Scope line says so, and each value stated for a registered name outside those sections is listed as not checked at this tier (Phase 3 applies this).
  • minimal — not meaningful (no GDDs to check).

Phase 1: Parse Arguments and Load Registry

Modes:

  • No argument / full — check all registered entries against all GDDs
  • since-last-review — check only GDDs modified since the last review report
  • entity:<name> — check one specific entity across all GDDs
  • item:<name> — check one specific item across all GDDs
