Tools Hidden in UI

12/10/2025, 6:40 PMSome tools I've created a while ago and use across multiple agents are not visible in the UI anymore. However, they're available when calling the ID via API. The tool is also now only showing up via ID on the agents it's connected to vs instead of its name.
Will this cause issues when referencing the tool by name (instead of ID) in the prompt?

get_weather Copy code
text
Use the get_weather tool to fetch the current weather.c

12/12/2025, 6:33 PMHi Cole,
It's important to consistently reference your tools by their exact name in assistant prompts rather than their ID. This ensures that your assistant uses the correct tool, even if its name isn't visible in the UI. As long as the configuration is correct and the tool is integrated properly in the assistant, using the tool's name will not cause issues. If the tool is still accessible via API and functions normally via ID, it should work without problems when referenced by name in prompts. For troubleshooting, you can refer to the [custom tools troubleshooting guide](https://docs.vapi.ai/tools/custom-tools-troubleshooting).
