What's Wrong?

I've noticed that when I open a new session and start chatting, Haiku automatically summarizes the previous session or sessions that haven't been summarized yet, leading to a large consumption of tokens.

like:

Especially when mixing with roocode, the roocode session does not generate a summary, so switching to Claude Code will summarize all roocode sessions, causing a large amount of token consumption.

What Should Happen?

The summary function can be turned off, or the total number of summary tokens can be limited.

It shouldn’t summarize all sessions that haven’t been summarized before; at the very least, it should have an upper limit.

Steps to Reproduce

If using roocode:

1. First, have a few conversations in roocode
2. Then switch to Claude Code in the same project
3. Type "hi" and press Enter
4. Using /cost, you can see token consumption that is several to dozens of times higher than usual

If don't use roocode:

1. Have a long session in Claude Code
2. Close and open a new Claude Code session in the same project
3. Type "hi" and press Enter
4. Using /cost, you can see token consumption several to ten times higher than usual
