-- **Cleaner code by default.** The agent now walks an explicit *reduction ladder* before writing code — does this need to exist at all, then the standard library, a native platform or framework feature, an already-installed dependency, one line, and only then the minimum custom code — so it reaches for the simplest working solution without trading away input validation, error handling, security, or accessibility. The same guidance layers into the `/best-practices` profile.
-- **New `cleanup-audit` skill.** A read-only, whole-repo audit that ranks over-engineering — what to delete, simplify, or replace with standard-library/platform equivalents — as the repo-wide complement to the diff-scoped `pythinker review diff --mode deslopify`. It applies no fixes.
-- **Smoother startup.** Update notices no longer appear twice; the hint now renders once on the persistent under-input line instead of also flashing as a footer toast.
+- **Safer silent updates.** The downloaded build is now staged beside the running executable and promoted at exit, instead of overwriting the live onefile bundle in place — eliminating mid-session `zlib: incorrect header check` crashes after a background update.
