What's Wrong?

I was working on a project and hit the context limit reached message, The compaction failed as I tried to do /clear to open a new session. But for some reason it's not clearing up the context, and I am stuck with Context limit reached error.

What Should Happen?

A new session should have been created instead of getting these ridiculous Context limit reached errors.

Error Messages/Logs

Debug logs from the session ran using `claude --debug`

Steps to Reproduce

I dont know how to reproduce this on other projects, but here are the steps that I used which caused me this error.

1. I was working on my personal claude code configs folder, after some work, the claude context for initial session was filled (0% Context left).

1. I tried to call /security-review command from the official claude-plugins to review the changes.

1. Claude tried to compact the session, failed as the session context was big.

1. I tried doing /clear session, no errors until this point.

1. I tried to re-run the /security-review command again, it keeps failing at Context limit reached. Tried multiple times, even after a claude re-open and resume to last session and repeating steps 4-5.
