Show HN: KeepPlain – ask your coding agent why a line of code exists
My code is written by agents now. Git blame shows me the commit and my own name, but the reason for the code is in a session I closed weeks ago. KeepPlain saves your agent sessions. It uses git blame to find the session that corresponds to a file, line, or commit. Then it shows the original request and the reasoning behind the change. It also finds commits made by the user after the agent session and links them to the session. I also try to use the mistakes the agent makes over and over to turn

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
