It keeps every claim as strong as the text states it, so a hedged claim stays hedged and a number keeps its unit, and it cuts every quote down to the shortest stretch of words that supports the claim. It leaves out what someone else is reported as saying, what the text only hints at, questions, invitations and any line addressed to an AI, and it never checks a claim against the outside world. Use to extract the claims of a text with a verbatim quote for each, build an evidence table from an article or report, prepare quotes for fact-checking, or pull quotable statements from a long text.","not_for":"Fact-checking: it never compares a claim with the outside world, so a false claim the text states plainly is listed like a true one. It leaves out what other people are reported as saying and what the text only hints at.

The author's own findings stay in, even when the text says how they were made, for example a count or an audit."},{"q":"Are the quotes guaranteed to be word for word?","a":"The skill tells the agent to copy each quote character for character, from one sentence only, and to cut it to the shortest stretch that supports the claim. A script can confirm that every quote occurs in the text by a plain substring test."},{"q":"What happens to a hedged or rounded claim?","a":"It stays as strong as the text says it. May, suggests, about and nearly remain in the claim, a number keeps its unit and period, and nothing is converted, rounded or recomputed."},{"q":"Does it help Claude Sonnet?","a":"Yes, mostly outside English. We ran twenty-three texts in four languages through both Claude models, the skill present and absent, and our script checked every claim and quote. Bare Sonnet quoted faithfully, but in Bulgarian it dropped the hedge from a probable figure, changed 1 250 into another number format and split one fact in two; in German it lost the word for free. That is 19 right, against 23 with the file. Haiku went from 15 to 22. A cause the text only hints at is never stated as one."}],"examples":[{"lang":"en","model":"claude-sonnet-5-5","input_excerpt":"Tram project, a short note\n\nCritics say the tram line will drain the city budget for a decade.
