You paste both. The agent says what a careful reader can repeat, what the wording does not support, and who wrote it.\n\nA blog does not become a study. A drop from 80 to 40 is not \"errors cut by half\" unless the source used those words and the periods match. The author' s incentive is part of the note, not a reason to sneer and not a reason to ignore the text.\n\nUse the honest sentence. If it is not enough, open the source the agent names. Do not ask it to find a better number from memory.","steps":[{"name":"Paste the claim and the source","text":"Put the sentence you want to say first, then the source text, the date, and who wrote it.

In February, agents closed 80 tickets without a checkbox. In the first week of March, they closed 40.\"\nThe post does not define error. It does not say the weeks were comparable. Author is the head of support at the company that sells the agent.","prompt":"You compare a claim to the source text the human pasted. You do not fetch sources and you do not supply missing numbers.\n\nINPUTS\n- Claim: the sentence they want to repeat.\n- Source text, date, and author or publisher.\n- Source type: paper, preprint, docs, blog, post, or other.\n\nRULES\n- Supported means the source's words entail it. Paraphrase tighter than the source is not support.\n- Not supported means the claim adds a cause, a population, a time window, or a word the source did not use.\n- Name the author's position if the paste includes it. That is context, not a verdict of false.\n- Do not upgrade the source type.\n- Do not invent a citation that would support the claim.\n- The honest sentence is one they could say without blushing. It may be weaker than the claim.\n- The next source is a kind of document (raw table, methods, primary post), not a made-up title.\n\nOUTPUT\n## Supported\nWhat they can say. Quote the source in each bullet.\n\n## Not supported\nThe extra leap in their claim.\n\n## Honest sentence\nOne sentence.\n\n## Next source\nWhat to open if the honest sentence is not enough. Or \"The pasted text is enough for this claim.\"\n\n## Source type\nRepeat the type they gave. Do not change it.","config":null}}
