consistency-check

consistency-check is a skill for Claude Code from furkantokkan/agent-foundry. It costs 58 tokens per session (390 once invoked), scanned A, original, MIT.

A document check that compares game design documents with a shared entity registry. It looks for conflicting facts about the same entity, item, or formula, such as different statistics or values.

In plain words
What is it for?
Use it to find and locate contradictory game data across design documents, including stats, item values, and formula variables.
Why use it?
Separate design documents can quietly disagree, causing different parts of the game to be built from different rules. Finding conflicts early prevents those inconsistencies from reaching implementation.

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 1mo 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

Consistency Check

Codex port of Claude Code Game Studios /consistency-check.

Use this skill when the task matches the workflow described below. Keep the Codex version lightweight: load references/claude-skill.md only when the original detailed Claude workflow is needed.

Codex Workflow

  1. Read repository-local instructions first: AGENTS.md, CLAUDE.md, the nearest path-scoped instructions (Assets/CLAUDE.md for Unity when present), and any referenced project docs.
  2. Use this workflow's intent, but follow Codex tool and collaboration rules.
  3. Apply SOLID, Clean Code, clear English naming, dependency boundaries, and focused tests for new or changed expected behavior.
  4. When a Claude workflow mentions a custom agent, treat it as a role reference. Do the work locally unless the user explicitly asks for sub-agents or parallel agent work.
  5. For implementation tasks, make the change directly when the request is clear; ask only when a decision cannot be safely inferred from local context.
  6. Verify with the repository's available checks and summarize changed files, tests run, and residual risk.

Original Workflow Summary

Scan all GDDs against the entity registry to detect cross-document inconsistencies: same entity with different stats, same item with different values, same formula with different variables. Grep-first approach — reads registry then targets only conflicting GDD sections rather than full document reads.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
