kunchenguid/no-mistakes — reverse-engineered prompt

Build me a small command line tool that sits in front of a normal git remote and acts like a safety gate for pushes. I want to push to this gate instead of directly to GitHub, and it should spin up a separate temporary workspace, run a review pipeline on the branch, check tests, docs, linting, and anything needed for a clean pull request, then only forward the branch when everything passes.

If something is safe and mechanical, let the tool fix it automatically. If it changes intent, stop and ask me to approve, fix, or skip it. I also want a simple terminal UI so I can review findings and continue the run, plus a way for coding agents to trigger the same flow with a slash command. Once the checks are green, it should open a clean PR for me automatically.

Please make it work on Mac, Linux, and Windows, with setup docs and a solid first run experience. Look up current docs online if you need to.
