fact-check
fact-check
A lightweight, single-claim adversarial verifier. You hand it one factual
claim; it gathers a little evidence, runs the same adversarial quorum
deep-research uses, and returns a verdict — supported / refuted /
inconclusive with cited evidence and a confidence — not a multi-page
report.
This is the point-check counterpart to deep-research. Where
deep-research fans out across 3–6 angles and dozens of sources to synthesize a
breadth report, fact-check spends a small budget on one claim and stops at
the verdict. It reuses deep-research's verify + quorum primitives directly:
schemas.py, rank.py, prompts.py, dedup.py in this skill's scripts/
are byte-identical copies of deep-research's (kept in sync by a repo-level
MD5 drift check). Only factcheck.py — the Stage-C verdict mapper — is new.
