Writing the prompt for a verifier that will "fact check" or "verify" a document or report against sources: hand it complete originals, never your own partial dump. And a verdict back that calls a claim "unsupported" or "fabricated" — check the gap is not in a source you trimmed.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fact-check subagents need complete primary sources ## Problem You dispatch a subagent to independently fact-check a document against its sources. To save context or tokens, you pass the agent a summary or partial dump of one source instead of the full original. The agent then reports a **false positive**: "Claim X is unsupported — the term appears in no source." The claim was actually fine; the supporting text was in the part of the source you abridged away. The failure is asymmetric and dangerous: a missing source region does not make the agent say "I can't tell." It makes the agent confidently say "unsupported" or "fabricated" — because absence-of-evidence reads as evidence-of-absence when the agent believes it holds the complete source. ## Context / Trigger Conditions - About to launch an Agent/Task subagent to "fact-check", "verify", "independently check", "stress-test", or "review the claims in" a document. - Assembling the source bundle / writing the prompt for that agent. - A verification subagent returns "claim X unsupported / appears nowhere / fabricated / not in any source" — especially for one specific claim while everything else verifies cleanly. …

How to install
mdr add wan-huiyan/agent-traffic-control/factcheck-subagent-needs-complete-sources@sha256:f1eaf5223cbae020The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
