Thanks for trying aider and filing this issue.

I'm not sure what you mean by "when the AI context is full" and "giving an error". Can you share output of the problem you are having.

Aider does make suggestions about how to reduce tokens when it hits token limits:

https://aider.chat/docs/troubleshooting/token-limits.html

When reporting problems, it is very helpful if you can provide:

• Aider version
• LLM model you are using
• Any stack traces or error messages
• A description of what you were doing when the error happened.

Including the “announcement” lines that aider prints at startup is an easy way to share some of this helpful info.

Aider v0.37.1-dev
Models: gpt-4o with diff edit format, weak model gpt-3.5-turbo
Git repo: .git with 243 files
Repo-map: using 1024 tokens

The current output when the context limit is reached is just an error message. The output I would like to see would be like this:

The context space is full and to continue you need to drop some resources from the chat.
Choose from of the following:

Index	Resource	Tokens
1	📑 workspace/myproject/src/main.py	1523 tokens
2	🌐 https://docs.github.com/en/actions/learn-github-actions/expressions	4987 tokens

12	🔰Aider ask chat history	3300 tokens
13	🔰Aider help chat history	700 tokens

Total Token Used: 198197 tokens (max context tokens: 200000)

Choose a number between 1 and 13 (Use comma to drop multiple resources, C to clear all chat context):
> 7, 13, 8

This would be a nice feature independently. Instead of clearing the full chat history or dropping all files, clearing specific components? Clearing part of the history would be nice too (e.g. keep last 10 commands only).
