Hey, you will need to specify the system prompt, in the ai agent,

Checkout this post I made, let me know if this helps, I can provide further details if needed. But in essence, you need to get the ai agent to call it use the tool.

Oh and also, some model don;t; run well with tools, openai 4o has been most reliable for me.

Thanks Samuel all good but the only problem that the main workflow doesnt pass data to the sub-agents workflows





how to make the principal ai agent pass data to the sub-agent to make the full process automated so i dont need to pass parametrs by myself like on the last picture in a way if i remove {“input”:“legorafi.fr”} the automation doesnt happen
Thanks you a lot for your help it very well appreciated

Hey @Chouayb_Attia

I don’t suppose if you put example json to pass in the tool description would it work?

I’ll try look further into it soon otherwise.

Best regards,

Samuel
