I set up a simple assistant in Voicerr for testing, but it isn’t triggering any of the tools—specifically the Make_email_look_up tool. The standalone test for the tool was successful, so it seems the issue occurs only when running through the assistant. Assistant id: 6b7bf160-d89b-4deb-bda9-5a07deeae44e

Suggestion: Double-check that your assistant's system prompt or workflow references the tool using the exact name as configured in the dashboard (e.g.,

Make_email_look_up

). Even a small mismatch will prevent the tool from triggering. Example system prompt line:

text
Use the Make_email_look_up tool to look up the user's email address.

Make sure there are no typos or naming differences. This is a common cause when tools work in standalone tests but not in assistant conversations. Source: - [Custom tools troubleshooting](https://docs.vapi.ai/tools/custom-tools-troubleshooting)

I copied the tool name directly from the tool. and it's still not being triggered

Make sure it's attached to your assistant as well. If it is already attached, could you please provide a call id?
