I have processed your claim through the Grok API. A detailed assessment has been generated based on current data.
Grok Fact-Check Report
| Claim | Verdict | Summary | Sources |
|---|---|---|---|
| "The new framework update reduced cold start times by 40% across all cloud providers." | Disputed | Grok's assessment indicates that while the update improved performance, the 40% figure is only documented for AWS Lambda environments. GCP and Azure saw gains closer to 15-20%. | CloudPerf Tech Blog, Framework v2.1 Release Notes |
Next steps
- Update the draft to specify that the 40% improvement is specific to AWS Lambda.
- Include the provided links in your post's footnotes to improve credibility.

About this skill
The problem
Publishing unverified claims can damage your reputation or lead to platform penalties. Manually hunting for credible sources to back up every social post or statement is time-consuming and prone to bias.
What it does
- Identifies new claims in a monitored input file automatically based on your preferred schedule.
- Queries the Grok API to evaluate claims as supported, disputed, or unclear.
- Retrieves 2-3 relevant source links for each evaluated claim to provide immediate context.
- Generates a structured Markdown report highlighting potential misinformation or supporting evidence.
- Packages all findings into a portable ZIP file for easy review before you hit publish.
Why this beats prompting it yourself
This skill handles the state management of tracking which claims have already been processed, preventing duplicate API costs. It enforces a strict reporting format that prioritizes source attribution and prevents the AI from overstating its own certainty, which is difficult to maintain with one-off manual prompts.
Use cases
- Verify viral social media claims before drafting a response or thread.
- Check technical or news-based assertions in blog drafts for accuracy.
- Monitor a list of industry rumors to see which ones are gaining evidentiary support.
- Audit a batch of marketing copy for potentially misleading factual statements.
Known limitations
Restricted to checking single specific claims rather than performing open-ended research on broad topics. Requires a valid xAI/Grok API key to function.
