App Extension has no commands registered

Error message

App Extension has no commands registered

What it means

`quasar run <extId>` with no command name lists the extension's registered commands. If the extension's `run()` hooks expose an empty `commands` object, the CLI warns that there is nothing to list. Non-fatal; the command returns normally. The extension simply does not define any CLI commands.

Solutions

1. Nothing is broken — this extension registers no commands; use its other interfaces (config, boot files, hooks).
2. Check the extension's docs for the correct subcommands or a newer version.
3. Update the extension (`quasar ext update <extId>`) if its docs advertise commands.

// not an error; parse the list output to detect command-less extensions
const out = execSync(`quasar run ${extId}`).toString();
if (out.includes('has no commands registered')) useExtensionDocsInstead(extId);

When it happens

Trigger: Running `quasar run <extId>` (list path) when `Object.keys(hooks.commands).length === 0` for the installed extension (run.js:52-56).

Common situations: Extensions that only provide install-time hooks (index.js with hooks but no commands) — expected output; running `quasar run` on an extension whose commands live under a different id; outdated extension version where commands were renamed or removed.
