Description

@open doesn't send the correct context or sometimes ANY content to the LLM

The Errors about config.json not found in the log output are instances where Continue tried to use config.json as the only context to my prompt, despite having multiple files open and config.json not being the active Tab. Also, the file is existant in that location. Note, that while I'm running VSCode on my Win11 Computer, my workspace resides on a Unix-Server using the Remote-SSH extension.

To reproduce

1. Add @open to your config.json
2. Try to use @open in your prompt
3. See that no context was given or the wrong has file been given as context
