Keep git history clean for each goal-oriented work unit. Use when Codex starts new implementation work, prepares a PR/review request, or needs to ensure unrelated commits/diffs are not mixed.
Create and edit GitHub pull requests with safe branch hygiene, Japanese-by-default PR writing, and markdown-safe PR descriptions. Use when Codex needs to create a PR, update a PR body or title, prepare PR body templates, or verify that PR markdown renders with real line breaks instead of escaped newline text.
