Restoring a checkpoint and an earlier point in the conversation

[liorshk]

It seems like there are 2 missing capabilities in the protocol right now but are available in the underlying CLIs:

“Restore to before this change/tool call”

When the agent has made a series of edits (fs writes, refactors, etc.), I’d like to let the user click a button like “Restore to before this step” and have the agent roll the session back to that checkpoint.

“Restore to an earlier point in the conversation”

Sometimes the user just wants to go back to an earlier point in the dialogue / plan (even if no files changed) and keep working from there.

Right now, different agents expose this in ad-hoc ways (e.g., gemini has checkpointing) but it seems like the current protocol doesn't support this.

Agree with this - "double escape" has become a useful (and necessary) convention for working with Agents - would be keen to support.

We would also love to see this feature! (branch out conversations, edit previous messages, etc.)
