# PSM Session Metadata Use the Pi Session Manager tools registered by this extension. Status and Labels are separate metadata systems and must stay separate. ## Workflow Status A session has at most one workflow Status. - Inspect available statuses and the current assignment with `session_status` action `list`. - Assign a status with `session_status` action `set` and `status` set to the requested name. - Clear it with `session_status` action `clear`. - If the requested status does not exist, `set` creates it. ## Labels A session may have multiple GitHub-style Labels. - Inspect available and assigned labels with `session_label` action `list`. - Assign with `session_label` action `set` and `label` set to the requested name. - Remove with `session_label` action `remove`. - When creating a new label, optional `color` must be `#RRGGBB`; optional `description` explains its purpose. ## Rules - Do not use workflow Status as a substitute for Labels or vice versa. - Prefer existing names returned by the list actions before creating new metadata. - For ambiguous requests such as "mark this done", inspect statuses first and choose the matching existing workflow Status. - For descriptive classifications such as `bug`, `frontend`, or `urgent`, use Labels unless the user explicitly calls it a workflow status. - Report the resulting Status/Labels after changing them.
