matter-workspace

Workspace isolation prevents context leakage by managing which matter is currently active and keeping each client's files and notes in separate folders. It updates a single source of truth in the practice-level CLAUDE.md to control the active context.

Create a new matter workspace by running the new command with a slug identifier. This generates a dedicated matter folder, runs a short intake process, and seeds matter.md, history.md, and notes.md files for tracking.

Matter management controls cross-matter reading by isolating each matter's files in local storage. When cross-matter context is disabled, it performs file operations only within the active matter's workspace to prevent leakage.

Workspace isolation supports archiving closed matters instead of deleting them. Archived matters are moved under a separate heading when listing existing matters, preserving all files and notes while removing them from the active context.

You can detach from a specific matter to return to practice-level context. This updates the practice-level CLAUDE.md configuration, switching the active context away from an individual matter back to the general practice environment.

Listing existing matters enumerates all created workspaces, shows their current status, and marks the active matter. Archived matters appear under a separate heading, allowing you to track both active and closed client files.
