verifying-before-citing

verifying-before-citing is a skill for Claude Code, Codex from redhuntlabs/wizard. It costs 31 tokens per session (1,127 once invoked), scanned A, original, MIT.

A source-checking discipline for claims, statistics, quotations, and attributions before they are cited. It compares the claim with the original source or clearly marks what remains unverified.

In plain words
What is it for?
Use it before publishing or sending work that cites research, numbers, quotes, or statements attributed to someone else. It is also useful when summarising what a source says.
Why use it?
It prevents errors introduced when information is copied through summaries, memory, or other secondary sources. If the original source cannot support the claim, the wording is qualified or removed.

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

verifying-before-citing 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 5d 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.

Verifying Before Citing

What this does

Forces every cited claim, statistic, quote, or attribution to be verified against the actual primary source before it appears in writing. Eliminates "secondhand citation drift" — the failure mode where a claim is true at the start of a citation chain but mangled by the third repetition.

When to use

  • About to publish, ship, or send anything that cites a source
  • About to attribute a quote to a person
  • About to cite a statistic, percentage, or numeric finding
  • About to summarize what a source "says" without having opened it recently
  • Whenever pulling from memory, AI output, or a secondary source

What you bring (Inputs)

  • The claim and its proposed citation
  • Access (or lack of access) to the primary source

What you get (Output)

A claim that you have personally verified against the primary source, OR an explicit hedge ("according to X, who cites Y, which I have not verified") OR the claim removed.

How it works (Steps)

This is a discipline. The behavioral structure is: a non-negotiable rule (below), an excuses-and-counters table to defeat rationalizations, warning signs to spot the moment of risk, and a hard gate that fires before publishing. Apply the gate at every citation; verify, hedge, or cut.

The non-negotiable rule

Every cited claim, quote, statistic, or attribution must be verified against the primary source — opened, read in context — before it leaves your hands. If you cannot, you must hedge explicitly or remove the claim.

Excuses and counters

If you think... Reality
"I remember reading this" Memory drifts. Open the source.
"I've cited this before" The source may have updated, or your prior cite may have been wrong. Open the source.
"An AI told me this is from X" AI-attributed quotes are routinely fabricated or misattributed. Verify or remove.
"It's a famous quote, everyone knows it's from X" Famous quotes are misattributed at the highest rates. Especially these. Verify.
"I'm short on time" The cost of a wrong citation lasts longer than the time to verify it. Verify.
"It's a small detail" Small wrong details destroy credibility for the rest. Verify.
"The secondary source seems reliable" Even reliable secondaries get details wrong. Open the primary.
"I'll mark it for fact-check later" "Later" doesn't happen. Verify now or hedge now or cut now.

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.
