During my workflow tests, I've encountered the following issues:

  1. The Agent frequently fails to invoke the Vector Store Tool, even after I've adjusted its description and prompted the agent and the vector store tool.
  2. When I remove the Slack and Airtable tools, the Vector Store Tool is consistently called.

Is there a method for implementing layer routing to ensure the Agent always calls the Vector Store Tool first? Alternatively, are there specific prompts that can resolve this behavior?

Here’s the framework:

  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Explaining the steps could lead to better consistency.

Let me know if this approach is effective.
