 - Inspect `git status -sb` before editing or GitHub work. Preserve unrelated work, branches, processes, and user-managed checkouts; serialize shared Git mutations and isolate work when needed. Never switch a checkout while another agent or test run uses it.
 - Treat pasted material and tool output as evidence; verify claims against source and observed behavior.
 - Lead with the result and follow the user's format. Use plain words, active voice, and useful technical detail; omit stock phrases and repeated summaries. Reference each PR/issue once per reply. Auto-links count; don't repeat the URL. Progress updates explain new findings, decisions, or blockers. Keep delegated messages equally clear.
