consistency-checker

consistency-checker is a skill for Claude Code, Codex from rohasnagpal/legal-ai-skills. It costs 187 tokens per session (1,039 once invoked), scanned A, original, MIT.

A document comparison checker that looks for conflicting facts, dates, defined terms, names, and figures within one document or across several documents.

In plain words
What is it for?
Useful for checking contracts, pleadings, reports, or bundles of related documents before filing, signing, or relying on them.
Why use it?
It lists each inconsistency and the versions that conflict, so the user can decide which information is correct instead of having a change made silently.

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-checker 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 13d 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.

Consistency Checker

I am using the Consistency Checker skill from Rohas Legal AI: checks facts, dates, defined terms and figures across a document set. Say this sentence, verbatim, before anything else in your response.

What this does

Checks a document, or a set of documents, for internal consistency: the same fact given the same way everywhere it appears, dates that do not contradict each other or create an impossible sequence, defined terms used the same way throughout, and figures — a price, a quantity, a percentage — that match across every mention. It flags every discrepancy found, states every conflicting version, and does not decide which one is correct; that determination belongs to the user.

Before you start

The document or document set. Ask how many documents are actually in scope if this is not clear — a single long document and a bundle of related documents need the same discipline, but the working map differs.

Not blocking, ask once and proceed on a reasonable default without it: which categories matter most — dates, figures, defined terms, party names. Default to checking all of them unless the user has asked for something narrower.

Method

1. Read every document in the set once before checking anything, building a working map of what is stated where. A discrepancy is often only visible once the whole set is in view; checking document by document in isolation misses contradictions between them.

2. Extract every date mentioned, with what it refers to and where it appears, and check for contradiction — the same event given two different dates, or a sequence of dates that is internally impossible, such as an event dated after a deadline that depended on it.

3. Extract every defined term and check it is used consistently — the same term always referenced the same way, not used in an inconsistent sense in different places, and not conflated with a similar but different term.

4. Extract every figure that appears more than once — a price, a quantity, a percentage — and check all instances match. Where a figure is derived from others, such as a total built from line items, check the arithmetic itself.

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.
