❯ cue help cmd
...
Available Commands:
  dump
...

❯ cue dump ./...

What did you expect to see?

Run the specified command

What did you see instead?

❯ cue dump ./...
command "dump" is not defined
Ensure commands are defined in a "_tool.cue" file.
Run 'cue help' to show available commands.

While dumping each directory all works

❯ tree .
.
├── app
│   └── app.cue
├── app.cue
└── dump_tool.cue

❯ cue dump .
name: root

❯ cue dump ./app
name: app

Test case: test.tar.gz

Hi @yujunz - apologies for the delay in replying to this (we've been catching up post migration in #1078)

Using ecb17c9, we I can't reproduce this:

exec cue dump ./...
cmp stdout stdout.golden

-- app/app.cue --
package test

application: app: _
-- app.cue --
package test

application: [Name=_]: {
	name: Name
}

releases: [
	for k, x in application {
		name: k
	},
]

application: root: _

-- dump_tool.cue --
package test

import (
	"encoding/yaml"
)

command: dump: {
	task: print: {
		kind: "print"
		text: yaml.MarshalStream(releases)
	}
}

for rls in releases {
	command: "dump-\(rls.name)": {
		task: print: {
			kind: "print"
			text: rls
		}
	}
}
-- stdout.golden --
name: root

Closing this for now, as we still aren't able to reproduce. More than happy to reopen if you can provide more details.
