How does Claude Inbox store messages?

Messages are stored as standard markdown files with YAML frontmatter within a hidden .claude/inbox/ directory inside each specific project.

Can I send messages between any projects?

Yes, as long as the projects are registered in a shared parent directory's CLAUDE.md file and you have configured the necessary file system permissions.

Does this skill handle project setup automatically?

Yes, it can create the global registry, validate project paths, set up the required directories, and update your Claude settings.json with the required permissions.

Is the inbox content secure and private?

The skill automatically adds .claude/inbox/ to your .gitignore file to ensure that internal messages and cross-project tasks are not accidentally committed to version control.

What are the different message types supported?

You can use 'note' for general information, 'request' when you need Claude to perform an action, and 'alert' for urgent notifications.
