Consider the following flow: you submit prompt A. Prompt A generates
some edits. You don't click on either "reject" or "keep"; they stay in a
pending state. You then submit prompt B, but before the agent outputs
any response, you click to edit prompt B, thus submitting a
regeneration.
Before this PR, the above flow would make the edits originated from
prompt A to be auto-rejected. This feels very incorrect and can surprise
users when they see that the edits that were pending got rejected. It
feels more correct to only auto-reject changes if you're regenerating
the prompt that directly generated those edits in the first place. Then,
it also feels more correct to assume that if there was a follow-up
prompt after some edits were made, those edits were passively
"accepted".
So, this is what this PR is doing. Consider the following flow to get a
picture of the behavior change:
- You submit prompt A.
- Prompt A generates some edits.
- You don't click on either "reject" or "keep"; they're pending.
- You then submit prompt B, but before the agents outputs anything, you
click to edit prompt B, submitting a regeneration.
- Now, edits from prompt A will be auto-kept.
Release Notes:
- agent: Improved the "reject"/"keep" behavior when regenerating older
prompts by auto-keeping pending edits that don't originate from the
prompt to-be-regenerated.
