Pinocchio: a skill to [try to] detect hallucinations

Luiz F. Weber — Thu, 23 Apr 2026 03:02:05 +0000

I created a AI skill called **Pinocchio **and I would like to share with you.

It's compatible with Claude's web version and Copilot in VS Code (since I tested).

Basically, the skill added an extra info to each answer, trying to show a percentage of certainty (maybe a lie detector?).

Well, when we use it with web searches, the results seem to have a sort of accuracy.

The tests above were proposed by Claude himself, as a self-assessment, meaning it could also be an attempt to reinforce that his answer is correct.

For those who want to test:

Can you guys help me in order to prove that the skill really works (or if this was just another hallucination)?

Thank you very much.

How many of you use Apache NiFi?

I work on a data integration project, in which data is ingested via NiFi to the cloud.

Is this software used by you or do you recommend another one for Big Data, IOT or another application?

We really like NiFi, because It is highly scalable, resilient, allows back pressure and is open source :)
