Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install blog-factcheck

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent extracts the load-bearing claims in your post, validates and fetches each cited URL, then scores whether the claimed passage is really there. Uncited claims are flagged with a search lead. You get a clear source-by-source report that also says what it could not verify.

Updated November 2, 2026

Report table listing each claim, its URL, match score and status.

Frequently asked questions

Can the agent check without web access?

No. It needs a page-fetching tool (WebFetch). Without one, every claim is marked "unverified" instead of being scored from memory.

Does it work on its own?

This skill points to sibling files (the `blog/references` folder) and to `/blog ...` commands from a larger suite. They are not included here: the agent works from the instructions in the file alone.
