SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill automates the end-to-end Reality Check analysis workflow for sources, enabling rapid ingestion, consistent evaluation, and provenance-backed claims registration.

Core Features & Use Cases

  • End-to-end analysis: Fetch a source, perform descriptive, evaluative, and dialectical stages, extract claims, and register them in the database.
  • Provenance & validation: Capture reasoning trails and validate results using rc-db, rc-validate and related tooling.
  • Use Case: Analyze a URL to produce a complete analysis file suitable for database import and future synthesis.

Quick Start

Run the skill against a URL: check <url> [--domain <DOMAIN>] [--quick] [--no-register] [--continue]

FAQPage Schema
How do I automate source evaluation and claims registration for web sources?

Automate source evaluation by executing a single command against a URL to fetch sources, run the three-stage analysis pipeline, extract claims, and register them in a provenance-tracked database.

What is the three-stage analysis pipeline for reality checks?

The three-stage analysis pipeline consists of descriptive, evaluative, and dialectical stages to systematically process sources and extract claims suitable for database import and future synthesis.

How do I validate analysis results and track provenance during a reality check?

Validate results and track provenance using rc-db and rc-validate tools, which capture reasoning trails and ensure deterministic data ingestion throughout the analysis workflow.

Can I run a quick reality check without registering claims in the database?

Yes, you can run a quick reality check without registering claims by passing the --quick and --no-register flags when executing the command against your target URL.

Do I need Python to run end-to-end source analysis workflows?

Yes, the end-to-end source analysis workflow relies on Python scripts for database operations and validation, alongside CLI tools to orchestrate deterministic data ingestion and analysis.

What's the best way to handle domain-specific sources during evidence evaluation?

Handle domain-specific sources during evidence evaluation by specifying the target domain with the --domain flag to ensure the analysis pipeline applies the appropriate contextual processing.
