Problem Statement

Often I find in a session I am working for a while and the context get's bloated so I want to reset it. /clear does this well, but when circling around a bug, you still want to keep some context to what the bug is and what we've tried.

This is also a problem when claude lays out "next steps" and you want to clear the context of the previous and successful work to focus on the next steps.

Proposed Solution

The idea with trim - as a similar implemented feature as /rewind is that you could choose a point to keep from, then it would keep everything that happened since that message and drop the context from before that point.

Alternative Solutions

The workarounds are to have it write to a md file or to copy paste that into a new session. It would be an ergonomic improvement to have /trim for context management as a first class feature.
