What is Fact Check?
The Fact Check skill is a specialized utility for Openclaw Skills that enables AI agents to perform rigorous verification of information. It systematically extracts claims from text and subjects them to a multi-stage validation process, querying reliable databases, academic papers, and official government records. This skill is indispensable for users who require high-integrity data and want to eliminate misinformation from their automated workflows.
By leveraging this tool within the Openclaw Skills ecosystem, developers can ensure that their agents don't just generate text, but provide evidence-backed conclusions. The skill utilizes a tiered source hierarchy to prioritize high-authority data like peer-reviewed journals and court records over unverified social media reports, ensuring the highest possible standard of truth.
Fact Check Use Cases
- Verifying the accuracy of statistics and data points in technical reports.
- Confirming the authenticity of quotes and primary source attributions.
- Cross-referencing news events across multiple independent international outlets.
- Validating historical dates and academic facts using scholarly publications.
- Investigating company information and product claims via official SEC filings and corporate statements.
How Fact Check Works
- Extract the specific claim or statement that requires verification from the provided context.
- Execute targeted queries across reliable sources, including news archives, academic journals, and official databases.
- Cross-reference the retrieved data across multiple independent sources to find consensus.
- Evaluate the credibility of each source based on the internal source hierarchy (Tier 1 to Tier 3).
- Deliver a structured verdict with clear evidence, highlighting any nuances or caveats identified during research.
Fact Check Setup
To deploy this skill within your Openclaw Skills environment, add the fact-check definition to your agent configuration. Ensure your agent has active web-search capabilities enabled.
# Install the skill via the Openclaw CLI
openclaw install fact-check
# Configure your trusted source API keys if required
openclaw configure fact-check --tier1-access
Fact Check Data Schema & Taxonomy
The skill produces a structured output to ensure clarity and traceability of every verification task:
| Attribute | Description | Formatting |
|---|---|---|
| Claim | The exact statement being investigated | Plain Text |
| Verdict | The final assessment (e.g., TRUE, FALSE, UNVERIFIABLE) | Uppercase Enum |
| Evidence | List of sources and specific supporting details | Unordered List |
| Notes | Contextual caveats, potential biases, or additional info | Markdown Text |
Fact Check Advanced Features
- Intelligent source hierarchy prioritization to favor Tier 1 evidence (journals, gov data).
- Automated claim type classification for customized search strategies (Statistics vs. News).
- Real-time distinction between unverified claims and demonstrably false information.
- Dynamic verdict updates when new evidence or primary sources emerge.
- Support for multi-agent workflows where one agent drafts and the Openclaw Skills fact-check agent audits.
