factcheck
Skill0 starsChanged 6 months agoNo licenceView on GitHub
Fact-checks claims, text, documents, URLs, and Claude's own responses using live web search. Trigger this skill whenever the user says 'fact check', 'fact-check', 'verify this', 'is this true', 'check this claim', 'is that accurate', 'can you verify', 'double-check this', or pastes text and asks if it's correct. Also trigger when the user shares a URL and asks whether its content is accurate, or asks Claude to verify its own previous response. Each claim gets a clear verdict — ✅ True, ❌ False, ⚠️ Misleading, or ❓ Unverifiable — with a cited source.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
11 rules. 0 are common, 11 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 5 edited versions we read keep these.
11
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.
“Common” is measured: kept by at least 6 in 10 of the 5 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
