SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill verifies the accuracy of claims and assertions by cross-referencing them with source code, documentation, and external information, ensuring factual correctness.

Core Features & Use Cases

  • Claim Verification: Checks specific statements for accuracy.
  • Evidence Citation: Provides concrete evidence (code, commits, URLs) for verification results.
  • Use Case: After a code audit, use this Skill to fact-check specific findings like "function X is not thread-safe" by having it search the codebase and git history.

Quick Start

Use the verify skill to check if the claim 'the user service handles invalid input' is true.

FAQPage Schema
How do I fact-check claims against source code and documentation?

To fact-check claims, you cross-reference specific assertions with source code, documentation, and external resources. The verification process gathers concrete evidence using search and read tools to confirm the statement's factual accuracy.

What is code audit claim verification and how does it work?

Code audit claim verification validates statements by searching the codebase and git history. It operates in serial or fan-out modes to handle varying claim loads, providing concrete evidence citations like code snippets and commits for each result.

How do I validate assertions in my codebase with evidence citations?

You validate assertions by running a verification process that searches source code and documentation for matching evidence. It returns concrete citations including code snippets, commits, and URLs that prove or disprove the original claim.

Can I verify multiple claims at once during a code audit?

Yes, you can verify multiple claims simultaneously using fan-out verification mode. This mode handles varying claim loads by distributing the evidence gathering process across multiple assertions, rather than processing them sequentially in serial mode.

Do I need specific tools to fact-check statements against my repository?

Yes, fact-checking statements requires tools like Grep, Read, Glob, Bash, WebSearch, and WebFetch for evidence gathering. These tools search the codebase, read files, execute commands, and fetch external documentation to validate claims.

When should I use automated assertion checking instead of manual review?

Use automated assertion checking when validating specific factual claims post-audit, such as confirming if a service handles invalid input. It provides concrete evidence citations faster than manual review, especially when processing high claim loads in fan-out mode.
