SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Run Chain-of-Verification (CoVe) on a draft or block of text to identify factual claims and verify them against sources, by spawning a fresh claim-verifier context.

Core Features & Use Cases

  • Ad-hoc fact-checking of drafts or text blocks to surface factual claims (citations, numerical facts, named entities) for independent verification.
  • Ensures fresh-context independence by forking a dedicated verifier and reporting which claims are supported, contradicted, or unverifiable.
  • Use cases include manuscript drafting, peer-review preparation, and post-hoc verification of claimed results.

Quick Start

Provide a draft or text block to verify, optionally supplying source pointers to guide the verification process.

FAQPage Schema
How do I fact-check a draft for verifiable claims before submission?

Fact-checking a draft for verifiable claims works by extracting citations, numerical facts, and named entities, then spawning a fresh claim-verifier context for independent verification. You receive a structured report classifying each claim as supported, contradicted, or unverifiable.

What is Chain-of-Verification and how does it work for academic writing?

Chain-of-Verification (CoVe) for academic writing operates by identifying factual claims in a text block and spawning a dedicated verifier with a fresh context to check them independently. It protects draft secrecy while delivering a structured verification report.

Can I use optional sources to guide the fact-checking process for a manuscript?

Yes, you can supply optional source pointers alongside your draft to guide the fact-checking process. The verifier uses these sources to independently verify extracted claims and report whether they are supported, contradicated, or unverifiable.

Does the claim-verifier require access to specific directories to check text blocks?

Yes, the claim-verifier requires access to the claim-verifier definition and the .claude/agents directory to function. This setup allows it to fork a fresh context for independently verifying extracted claims from your draft.

How do I handle unverifiable claims when running a post-hoc verification on peer-review drafts?

Post-hoc verification supports configurable failure behavior to handle unverifiable claims. You can define how the system responds when the independent verifier cannot confirm or contradict extracted claims within the structured verification report.
