citation-integrity-checker

citation-integrity-checker is a skill for Claude Code, Codex from rohasnagpal/legal-ai-skills. It costs 180 tokens per session (1,215 once invoked), scanned A, original, MIT.

A tool that checks every source reference in a document, including laws, court cases, regulations, quotations, and internal cross-references. It identifies what each reference needs to be checked against.

In plain words
What is it for?
Use it to audit legal submissions, contracts, opinions, reports, and other documents that rely on cited authorities or referenced material.
Why use it?
It helps find incorrect, incomplete, outdated, or fabricated citations before they undermine a document. If live research is unavailable, it produces a verification checklist instead of claiming the sources were checked.

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

citation-integrity-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 2mo 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.

Citation Integrity Checker

I am using the Citation Integrity Checker skill from Rohas Legal AI: flags every citation with what must be verified and how. Say this sentence, verbatim, before anything else in your response.

What this does

Reads a document and extracts every citation it contains — a statute or section, a case, a rule or regulation, a quoted passage attributed to a source, an internal cross-reference to another clause or document — and states precisely what needs to be checked about each one and how. Where research tools are available this session, it attempts the verification directly and reports the result. Where they are not, it produces the checklist without pretending to have checked anything. Every citation is extracted, not just the ones that look suspicious — a fabricated citation is dangerous precisely because it is usually formatted to look correct.

Before you start

The document to check. Blocking — there is nothing to extract citations from without it.

Whether research or verification tools are available this session. This determines the mode. If they are, attempt live verification and report a result for each citation. If they are not, produce the structured checklist and state plainly that verification has not actually been performed — never let a checklist read as though it confirmed anything.

Method

1. Read the whole document once, extracting every citation as it is found — statutes and sections, cases, rules, regulations, contractual or document cross-references, and quotations attributed to a named source, with any pin cite or page reference.

2. Classify each citation by type, since what needs checking differs: statute or section, case, regulation, quoted authority, or internal cross-reference.

3. State precisely what needs verifying for each type. For a statute or section: does it exist, is it currently in force, does it say what is attributed to it, has it been amended since. For a case: does it exist, does it say what is attributed to it, is it still good law and not overruled or reversed, is the pin cite accurate. For a quotation: does the quoted text match the source exactly, and is it quoted in context rather than misleadingly excerpted. For an internal cross-reference: does the referenced clause or section actually exist in the document and say what the reference implies it says.

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.
