Sharing Claude Code permissions across a team with a committed settings.json

Individual developers' Claude Code approval habits do not scale across a team, leaving new hires unsure which prompts matter. The recommended fix is a shared permissions file committed to the repository, with a local settings file for personal exceptions and optional managed settings for rules no one can override. A starter configuration allows routine safe commands like tests and lint, asks before risky actions such as pushing, and denies access to secrets. Rules from different files are merged, and deny rules are checked first, so a team deny cannot be overridden by a local allow. The article also notes that permission rules are not a complete security boundary, since the same command can be run in ways that bypass text matching.
