Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
The fact-check skill enables AI agents to verify the accuracy of claims, statements, or information by cross-referencing them with reliable sources. It can identify potential misinformation, confirm factual details, and provide evidence-based responses.
When to use it
- Before sharing news articles or social media posts to ensure they are accurate.
- During research to validate data from unknown or unverified sources.
- In academic or professional settings to support claims with credible references.
- When reviewing content for factually incorrect statements that could lead to misinformation.
Key capabilities
- Cross-referencing information against trusted databases and sources.
- Identifying potential biases or inaccuracies in provided statements.
- Providing citations or links to verified sources when possible.
Example prompts
- "Is the claim 'Vitamin C can cure the common cold' accurate?"
- "Verify if the statement 'The moon is made of green cheese' is true."
- "Check whether the article about climate change from this website is reliable."
Tips & gotchas
- Ensure that the AI agent has access to up-to-date and credible sources for accurate fact-checking.
- Be aware that some claims may be context-dependent, so additional clarification might be needed for full accuracy.
