update-profile

desktop-manager: update-profile

For one-off field changes against an existing profile. If the user wants a wholesale re-profile, run /desktop-manager:onboard instead.

Workspace resolution

PLUGIN_DATA_DIR="${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/desktop-manager"
PROFILE_FILE="$PLUGIN_DATA_DIR/profile.json"

If $PROFILE_FILE doesn't exist, point the user at /desktop-manager:onboard and stop. Don't bootstrap a partial profile from this skill.

Arguments

$ARGUMENTS is parsed as <field-path> [new-value]. Examples:

• desktop.session_type wayland
• policies.sudo_mode passwordless
• packaging.preferred_for_gui_apps flatpak
• services_of_interest +bluetooth (append)
• services_of_interest -bluetooth (remove)
• quirks +"AMDGPU resets randomly under heavy load" (append free-form)
• hardware.gpu (no value → re-detect just this field via lspci -k)

If no arguments, show the user the current profile and ask which field they want to change.

Procedure

1. Load $PROFILE_FILE. If version doesn't match what this plugin understands (currently 1), refuse and tell the user to re-onboard.

2. Resolve the field. Walk the JSON path. If the path doesn't exist, reject with the closest sibling suggestion — don't silently create new top-level fields.

3. Compute the new value:

   • Bare new-value → set the field.
   • +value on a list field → append (deduplicate).
   • -value on a list field → remove.
   • No value given → re-run the auto-detection probe for that field from onboard's table and propose the result.

4. Diff and confirm. Show old value, new value. Wait for explicit user confirmation.

5. Write. Update last_profiled to now (UTC ISO-8601). chmod 600 "$PROFILE_FILE".

6. Tell the user what changed and which commands are affected. For example, if desktop.session_type flipped to wayland, mention that troubleshoot-hardware will now use wlr-randr instead of xrandr.

Editable fields

See lib/PROFILE.md for the full schema. All fields in there are user-editable except version, which is owned by the plugin.
