deep_research — a deterministic multi-source research gatherer.
The tool does the mechanical heavy lifting of a research pass: fan out a set
of sub-queries across the configured search provider, deduplicate the
sources, concurrently fetch the top pages (reusing the SSRF-guarded
web_fetch path), and return a citation-numbered evidence digest with
source-agreement signals. Semantic cross-verification and synthesis are left
to the agent (or the researcher specialist) reading the digest — the tool
itself runs no LLM, so it is cheap, fully deterministic, and unit-testable.
