SAMRADDHASHRIVASTAVATECH Claim verification
Test a claim against multiple independent sources and return a confidence verdict.
When to use

- Weighing whether a source's statement is corroborated.
- Required as a gate inside
fact-checkinganddeep-research.
Tools used
verify_claim— from aclaim, optionalphrasesto verify against, and averification_threshold(default 0.5).
Workflow
- Reduce the claim to its verifiable kernel.
verify_claim(supplyphrasesto aim the evidence hunt).- Look for independent confirmation, not echo chambers republishing one original.
- Report the verdict + the evidence trail; flag uncertainty explicitly.
Input schema
{ "claim": "str", "phrases": "list[str]", "verification_threshold": "float" }
Output schema

Security
Independence is the whole game: sources that copy each other do not corroborate. Always surface the evidence, not just the verdict.
