Commit progress so a model switch can't undo it
A silent model switch undid a nearly finished fix · Reddit r/cursor · u/SausageSniffer420 · May 2026
Hours into a hard bug, about 90% fixed, the session switched models. With no git commits along the way, most of the work was lost.
The honest numbers
- Says about 90% of the way to a fix

Lesson
Commit small working steps as you go. Git is your undo button when the AI changes course.

Copy this into your own AI tool (Cursor, Lovable, Claude Code, Bolt…). It's general guidance written by us. Review what the AI suggests before applying it.
I keep losing context with Cursor (it forgets rules, re-asks about my project, or a model switch undoes work). 1) Create a short project brief file for the repo (e.g. AGENTS.md or CLAUDE.md): stack, how to run it, key files, files never to touch, and coding rules. 2) Tell me which rules should be enforced by tools instead of prompts (git hooks, linters, tests, ignore files) and set those up after I approve. 3) Remind me to commit working steps with clear messages, and show me how to roll back. Keep the brief under 60 lines.
