evidence-add Tool
Save a short citable snippet. Every fact you will put in your final answer must come from an evidence entry.
REQUIRED: source (URL or identifier), note (1-line summary), snippet (<=1KB of exact text)
RULES:
- Save the SMALLEST span that supports the claim. Don't dump a paragraph when one sentence is enough.
- One note = one claim. If a page has three useful facts, store three entries.
- Snippet must be verbatim from the source, not paraphrased.
- The returned id is what you cite in your final answer (e.g.
per e3a1f2).
EXAMPLE:
{"name": "evidence-add", "input": {"source": "https://en.wikipedia.org/wiki/Turing_machine", "note": "Turing machine introduced in 1936", "snippet": "The Turing machine was invented in 1936 by Alan Turing."}}
Workflow
- Extract smallest span: Save only the text needed to support the specific claim
- One entry per fact: If a source has multiple facts, create separate evidence entries
- Keep it verbatim: Snippet must be exact text from the source, not paraphrased
- Cite by ID: Use the returned ID in your final answer (e.g.,
per e3a1f2)
