Projects deep-dive

Use Projects to carry context, files, and instructions across sessions.

Project = multi-file, persistent context, weeks-long. Cowork = single doc, hours-long. Chat = one-off question, minutes-long.

A good Project has CLAUDE.md, two to five context files, and project-specific instructions.

Do not put secrets, large binary files, or transient state into a Project.
