We also walk through how /fleet mode and autopilot can handle massive refactoring tasks while you step away.

pre-commit ci
Developers spend a fair chunk of time during their development flow on fixing relatively trivial problems in their code. pre-commit.ci both enforces that these issues are discovered (which is opt-in for each developer's workflow via pre-commit) but also fixes the issues automatically, letting developers focus their time on more valuable problems.
