Grounding & anti-hallucination

“It won’t make up a citation” is a concrete, demonstrable promise in CoSci — not a hope. That’s because literature and citation work is grounded in real data, not generated from a language model’s memory.

Real tools, via ToolUniverse

Literature sweeps, citation checks and protein/structure context reach live scientific databases through the ToolUniverse tool layer:

• PubMed · Europe PMC — biomedical literature and open full-text
• Semantic Scholar — citations and the citation graph
• UniProt · InterPro — proteins and their domains
• PDB — experimental structures

Every external call is cached, governed, and shown in Agents → Tool runs. See scientific tools for the workflows this exposes.

The citation-existence gate

When CoSci makes claims that cite the literature, a citation gate audits each claim against references that actually exist. A claim backed by a paper that can’t be found doesn’t pass. This is what turns “grounded” from a slogan into a check.

Why this matters

A PI can’t stake work on invented references. By making grounding a tool call and citation existence a gate, CoSci makes the anti-hallucination property structural — it comes from how the system is built, not from asking the model nicely.
