kunchenguid/backpass ? reverse-engineered prompt

Build me a local first command line tool for macOS and Linux that helps improve an agent memory file like AGENTS.md by reading past coding assistant sessions from disk and suggesting better instructions from real evidence.

I want it to scan the transcript folders for a few common agent tools, figure out which sessions belong to the current repo, distill the useful parts, and then use that to propose small edits to the memory file. It should never write automatically, only show me the suggested changes with quotes from the sessions that support each one, and let me accept or reject them one by one. Keep it careful about secrets, keep the output under a small token budget, and make sure the same idea only gets added when there is evidence from more than one session.

Please make it work as a simple CLI with commands like init, scan, and apply, and let it run without any API keys of its own. If you need current docs for any of the harnesses or local storage formats, look them up online first.
