verify-claims

verify-claims is a skill for Claude Code, Codex from ShaishavMaisuria/research-paper-lifecycle-skills. It costs 60 tokens per session (2,874 once invoked), scanned A, original, Apache-2.0.

A paper-review tool that checks whether important statements are supported by the paper’s results, tables, figures, experiments, or citations.

In plain words
What is it for?
Use it to audit claims, check first or state-of-the-art statements, compare prose with reported numbers, and prepare a rebuttal or final paper.
Why use it?
It exposes overstatements and mismatches—such as claiming a major improvement that the evidence does not show—before reviewers do.

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

verify-claims 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/claim_audit.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verify Claims

The claim-to-evidence gate. Reviewers attack the gap between what a paper asserts and what it shows — an unbacked "we are the first", a "state-of-the-art" with no comparison, a "significant improvement" with no test, a speedup stated in the text that the table does not support. This skill finds those candidate claims, makes the author map each to its evidence, and produces a claims matrix (claim · location · evidence · status) so the gap is visible and closeable before a reviewer finds it.

It is the content counterpart to verify-citations: that skill proves each reference in the .bib resolves to a real paper; this skill proves each load-bearing sentence in the prose is backed by something in this paper (a number, a figure, a table, an experiment) or a real citation. Run both before any draft, rebuttal, or camera-ready leaves the machine.

When to use

  • The user asks to verify / audit / check claims (not citations): "are my claims supported?", "am I overclaiming?", "do my results match my tables?"
  • Before a rebuttal — reviewers' top complaint is unsupported or overclaimed contributions; close the gaps first, or arm the rebuttal with the evidence.
  • Before camera-ready or arXiv — last chance to soften an indefensible "first" or fix a number that drifted out of sync with a revised table.
  • After polish-tables-figures regenerated a table, to confirm the prose still matches the new numbers.

Inputs

  • The paper's .tex (main file; the script follows \input/\include). Find it next to the .bib, or via the file with \documentclass.
  • The author, in the loop: the skill cannot decide whether a claim is true — it surfaces candidates and the author supplies (or admits the absence of) the evidence. Copilot, not pilot.
  • Optional: .paper-memory/profile.ymlrisk_appetite and contribution_type set how hard the author wants to push novelty vs. hedge (see Memory).

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.
