agora: Skill for Claude Code

.claude/skills/verify-claims/SKILL.md

verify-claims is a skill for Claude Code from DanceNitra/agora. It costs 163 tokens per session (1,922 once invoked), scanned A, original, MIT.

A pre-publication fact-checking workflow for written material. It checks factual claims, numbers, studies, quotes, and other sources against the original paper, dataset, filing, or other primary source.

In plain words
What is it for?
Use it to review posts, research notes, outreach replies, press material, or any draft containing factual claims or citations. It can provide a verification banner and guidance for keeping claims safe.
Why use it?
It helps catch incorrect, incomplete, or unsupported claims before they are published or sent outside the project. It returns a verdict and corrections for each checkable claim.

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 9d 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.

Verify Claims — adversarial pre-publish fact-check

What this does

Takes a draft (a post .md, a Crucible note, an outreach reply, pasted text) and, before it goes public, independently verifies every checkable claim against its PRIMARY source — not a blog summary, the actual paper/dataset/filing. It returns truthful verdicts (CONFIRMED / PARTIALLY CONFIRMED / UNVERIFIED / FALSE), the exact corrections, a verification banner, and a claim-safety guide, then patches the draft. This is the operational form of Agora's hard rule "verify measured numbers vs the source before any public citation" (we once posted an unreproduced "+144%"; never again). It is the same adversarial pass that, run inside storm-research, caught a misattributed arXiv ID, a 1,692→1,689 sample-size error, and a fragile vendor stat — all before publish.

Self-contained: built-in Agent (general-purpose), WebSearch/WebFetch, Read/Edit. No external services.

When to use (hard gate)

Run this and pass it BEFORE: rendering/publishing any post, recording a public Crucible entry, posting a gated outreach reply or press piece, or approving any outward action that cites a number or source. A piece that has not passed this is not ready to publish.

Process

1. Extract the checkable claims

Read the target. Pull EVERY independently-checkable assertion:

  • each cited number / statistic / effect size / percentage / dollar figure / date / sample size,
  • each named study / paper / author / venue / arXiv-or-DOI id,
  • each direct quote or "X said/found Y",
  • each claim of priority ("first to…", "nobody has…"). List them. Our OWN measured numbers count too — re-check them against server/.lab.json / the lab script / re-run, not against a vault note (a number in a note is NOT verified).

1b. Run the CONSTRUCTION gate on every artifact behind one of OUR numbers (mandatory, blocking)

python -X utf8 tools/publish_gate.py <draft.md>        # audits every runnable model the draft links
python -X utf8 tools/publish_gate.py <probe.py> ...    # or name the artifacts directly

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.

It adds 163 tokens to every session and 1,922 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
