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

1. Extract smallest span: Save only the text needed to support the specific claim
2. One entry per fact: If a source has multiple facts, create separate evidence entries
3. Keep it verbatim: Snippet must be exact text from the source, not paraphrased
4. Cite by ID: Use the returned ID in your final answer (e.g., per e3a1f2)
