Use

The default review mode is full. Pass quick for a shorter review, and add the screen, flow, or feature after the mode.

In Claude Code, as a plugin. Plugin skills are namespaced, so every skill is prefixed with interfaces:.

/interfaces:better-interface
/interfaces:better-interface quick
/interfaces:better-interface full checkout flow

In Claude Code, installed with the skills CLI:

/better-interface
/better-interface quick
/better-interface full checkout flow

In Codex:

$better-interface
$better-interface quick
$better-interface full checkout flow

The prefix only affects skills you invoke by name. The other six skills are picked up automatically from context either way.
