The Source Cross-Check Tool
Compare a statement against multiple independent sources to see whether they agree, disagree, or are silent — so an agent can flag contested claims instead of trusting a single source.
Autonomous agents fail quietly
An agent that can act is only useful if it remembers, plans, and checks its own work. Without a cognitive core, agents forget context, skip steps, and state wrong answers with full confidence — and you find out too late.
No memory across runs
Agents start from zero every session, re-asking what they were already told.
Acting before thinking
Without an explicit plan, agents take the first path, not the right one.
Confident wrong answers
Nothing checks the output, so mistakes ship as if they were facts.
No accountability
When it goes wrong, there is no trace of why the agent did what it did.
Source Cross-Check, without the risk
Capability
What it does
Corroborate a claim across independent sources.
it checks a claim against multiple independent sources and reports where they agree or conflict.
- Multi-source corroboration
- Agreement / conflict summary
- Surfaces the disagreement
- Flags lone claims
Assignable to any agent
How it works
Predictable, inspectable behavior
Designed to be reliable.
it aligns the claim to each source and returns an agreement summary with the conflicting passages, so an agent can distinguish consensus from a lone assertion.
Every call logged
Governance
Private, governed, on-premise
Runs inside your perimeter.
This tool runs inside your perimeter, scoped per user with full audit logging, so the agent’s reasoning, memory, and decisions stay private and accountable — never sent to a third-party service.
Per-tenant, logged
Parameters
The source_crosscheck tool accepts these inputs when an agent calls it. Required inputs are flagged.
How the Source Cross-Check tool works in practice
Source Cross-Check is an agent core & quality tool you assign to a VDF AI agent. It checks a claim against multiple independent sources and reports where they agree or conflict. Its hallmarks — Cross-check, Corroborate, Consensus — let an agent rely on it as a dependable step in a larger task rather than a brittle one-off script.
Under the hood, it aligns the claim to each source and returns an agreement summary with the conflicting passages, so an agent can distinguish consensus from a lone assertion. It expects claim and sources as required inputs, so calls are explicit and easy to audit. Every call is scoped to the requesting tenant and written to an audit log, so the capability is safe to run inside a regulated, on-premise environment — the same governance model behind every VDF AI tool.
Teams reach for Source Cross-Check when they need to handle contested facts, due diligence, and news synthesis. It rarely works alone — pair it with Citation Verifier, Fact Checker, and WEB Search to build a complete, governed workflow, then compose those steps into an on-premise VDF AI Network.
Where Source Cross-Check pays back
Contested facts
Flag a claim only one source makes.
Due diligence
Confirm a figure appears consistently across filings.
News synthesis
Separate widely reported facts from single-source rumors.
Research rigor
Show where the evidence agrees and where it splits.
Assigned to agents, orchestrated as networks
On VDF AI, an industry’s use cases map to agents, and you assign tools like this one to those agents. Compose multiple agents into a governed, on-premise network.
What changes after you assign it
Questions about the Source Cross-Check tool
What is the Source Cross-Check tool?
It checks a claim against multiple independent sources and reports where they agree or conflict. Assigned to a VDF AI agent, it runs under role-based policy with full audit logging so the capability is safe to use in production.
What does it return?
An agreement summary — which sources support, contradict, or are silent on the claim — with the relevant passages.
How is it different from fact-check?
Cross-check compares across sources you supply; fact-check assesses a claim’s truth, often gathering evidence itself.
What inputs does the Source Cross-Check tool need?
It requires claim and sources. Each parameter is validated when an agent calls the tool, and the full call is logged for audit.
Which tools pair well with Source Cross-Check?
Source Cross-Check is commonly assigned alongside Citation Verifier, Fact Checker, and WEB Search. On VDF AI you compose several tools and agents into a single governed, on-premise network.
Does it run on-premise?
Yes. Like every VDF AI tool, it can run on-premise or in your sovereign cloud, scoped per user and audit-logged, so your data never leaves your perimeter.
How do agents use it?
You assign the tool to an agent under a role-based policy; the agent calls it as one step in a task, and several agents and tools can be orchestrated together as a governed VDF AI Network.
