Wuji CLI User

A user profile is a local record of one person's calibration data under ~/.wuji/sdk. wuji user manages these profiles and moves calibration bundles between machines. Every subcommand is a local operation (registry + files, no device connection) and supports --json.

Mental Model

• A profile is keyed by its name — this is the only identifier the user sees (there is no OS account link; the SDK's internal id is not exposed).
• Calibration is scoped per profile: the hand model is per user + hand side; tactile is per device SN.
• The default user cannot store a calibrated hand model. wuji calib hand-model refuses to run until a named profile is active. Tactile calibration is device-specific and may be stored, inspected, exported, or imported while Default is active.
• Stateless and local: no persistent connection, no device involved.

Commands

Add --help to any subcommand for details.

Safety (read before destructive actions)

• delete is irreversible and removes all of a profile's calibration data. In a Human TTY, omitting the name opens a selector that excludes Default, marks the current profile, and defaults to Cancel operation; after selection, the CLI prints what will be removed, suggests wuji user export for a backup, and asks for a default-No confirmation. Do not select a profile on the user's behalf. Do not pass --yes unless the user has explicitly authorized deleting that specific profile; --yes requires the name to be present. Default cannot be deleted.
• import overwrites the target profile's artifacts. Preview first with --preview (or read the interactive Cliclack preview) and relay the source user, bundle version, contents, and any conflicts before proceeding. In Human TTY mode, use the fixed-footer menus to choose whether to overwrite the current profile, create a new profile, or cancel; --as <name> selects the new-profile path up front. When the bundle comes from a different user and the target already has artifacts, the CLI backs them up under calibration-import-backups/ before overwriting.
• A bundle containing a hand model cannot be imported into Default: Default cannot hold hand model artifacts, so the CLI refuses (exit 5) instead of succeeding with the model silently dropped. Import into a named profile with --as <name>, or wuji user create <name> --switch first. A tactile-only bundle still imports into Default normally.
• Import is not atomic. If it fails partway, the profile can hold a mix of new and previous artifacts. The CLI says so, points at the backup directory when one was made, and tells the user to verify with wuji user show <name>. Relay that recovery path — do not retry blindly.
• Non-interactive modes require explicit consent: in --json/--jsonl or without a TTY, use --preview for a read-only import preview or -y/--yes to apply the import; delete requires both an explicit profile name and --yes. Only add a confirmation flag after confirming the user's intent — never as a default.
• export never clobbers silently: in Human TTY mode, exporting over an existing file asks for confirmation and defaults to No; non-interactive or structured output still requires --force. This includes a directory target whose auto-generated name collides. Exporting a profile with no calibration data fails and tells the user to complete a calibration first — nothing is written.
• Default is protected: it cannot be deleted or renamed. Deleting the current profile resets the current user to Default (the CLI reports this).
• Never choose among multiple profiles on the user's behalf. In a Human TTY, wuji user switch without a name opens a selector that includes Default, marks the current profile, and defaults to Cancel operation; let the user choose. Outside a TTY, supply the explicitly requested profile name. When a profile name is not found, run wuji user list, relay the available profiles, and ask which one to use.

Calibration Workflow

First-time or default-user flow:

wuji user create alice -d "Left-hand operator" --switch    # named profile is now current
wuji calib hand-model               # calibration is allowed

If hand model calibration reports the default-user guidance (create / switch first), create and switch to a named profile, then retry. Tactile calibration does not require a named profile. Obtain confirmation before starting either calibration workflow (see the wuji-cli-calib skill).

Exit Codes and JSON

With --json/--jsonl, success prints one document per command; errors print {"error":{"code":N,"message":...}}. Branch on code (and the process exit code), not on parsing the message text.

create, switch, rename, and delete all report current_user — the active profile after the action, whether or not this action changed it. Read it from the command's own output instead of following up with list --json; the field is always present, so no branching on "did this affect me" is needed. rename also reports previous_name, so a script can confirm which profile it just renamed.

Examples

wuji user list --json                              # Inspect profiles + calibration state
wuji user create alice --description "Left-hand operator" --switch  # Create and activate a profile
wuji user show --json                              # Current profile's artifacts
wuji user export ./alice.zip                       # Export current profile
wuji user import ./alice.zip --preview             # Inspect a bundle without importing
wuji user import ./alice.zip                       # Preview, then confirm import
wuji user import ./alice.zip --as bob               # Import into a fresh profile
