What happened?

I have a bunch of agent defintions in my local .gemini/ folder.

When I make a query, the filesnames are being read into context, and then the files themselves are read into context, and the model uses these instructions for completion.

This is not expected. The main agent / instance should not get polluted with preferences / content from agents definitions.

What did you expect to happen?

It just uses the model to generate a completion using only the system prompt and user instructions. Not other information that is lying around.

TL;DR

The issue can be mitigated by ensuring that the agent definitions in the local .gemini/ folder do not interfere with the main agent's context.

Guidance

  • Verify that the agent definitions are properly isolated from the main agent's context by checking the code that reads the filenames and files into context.
  • Check the documentation for the Gemini CLI to see if there are any configuration options or flags that can be used to prevent the agent definitions from being read into context.
  • Consider modifying the code that reads the agent definitions to only read the necessary information and ignore any unnecessary data.
  • Review the security and isolation features of the Gemini CLI to ensure that they are properly configured to prevent unintended access to sensitive information.

Notes

The exact cause of the issue is unclear, but it appears to be related to the way the agent definitions are being read into context. Without more information about the code and configuration, it is difficult to provide a more specific solution.

Recommendation

Apply workaround: Modify the code that reads the agent definitions to properly isolate them from the main agent's context, as this is the most likely cause of the issue and can be addressed without waiting for a potential fix in a future version.
