Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.6.4

Ollama Version (if applicable)

No response

Operating System

Ubuntu 22.04

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have listed steps to reproduce the bug in detail.

Expected Behavior

The RAG_TEMPLATE is not applied to documents retrieved by tools. Modifying the RAG_TEMPLATE to include debugging instructions or other changes does not affect the output when documents are retrieved using a tool.

Actual Behavior

The RAG_TEMPLATE is not applied to documents retrieved by tools. Modifying the RAG_TEMPLATE to include debugging instructions or other changes does not affect the output when documents are retrieved using a tool.

Steps to Reproduce

  • Configure a tool to retrieve documents.
  • Modify the RAG_TEMPLATE to include a debugging instruction or a noticeable change.
  • Execute the tool and observe the output and subsequent assistant response.
  • Verify that the RAG_TEMPLATE changes are not reflected in the assistant response.

Ideally we would have the possibility to directly modify/add messages within the tool

You should use a Pipe Function for this and not a tool.

thank you,

I just wonder what do you mean by "this".

    1. Pipe is the solution to directly modify/add messages within the tool. This is true I am sorry I am quite new using this (2days).
    1. Or the fact that the RAG_TEMPLATE does not apply to the citations added by a tool is expected, and to apply the RAG_TEMPLATE myself via a pipe that would detect citations ?

Or both ?

Bests,
