Before resuming a long session, ask for a short recap of goals and forbidden paths.
Drop chatty history; keep failing tests, allowed directories, and the last good commit.
If the last turn made a bad edit, revert or reject it before continuing.
Start the resumed turn with one small verification task, not a large refactor.
Pin the recap in AGENTS.md when the same constraints will last all day.
Change one variable at a time and confirm what actually helped.
If a company policy is involved, rule that out before chasing client settings.
Write the working steps into a short checklist for next time.
Export or screenshot a good setup so reinstalls are faster.
If it still flakes, retest on a clean network such as phone hotspot.
