#[editor_commands] takes no arguments

Error message

#[editor_commands] takes no arguments

What it means

editor_commands_impl rejects any attribute argument: the macro must be written exactly as bare #[editor_commands]. Any token content inside #[editor_commands(...)] fails with this spanned error before the module is inspected.

Solutions

1. Remove the argument and use bare #[editor_commands]
2. If per-module configuration is needed, wrap or rename modules instead of passing arguments to the macro

Example fix

// before
#[editor_commands(some_arg)]
mod commands { /* ... */ }

// after
#[editor_commands]
mod commands { /* ... */ }

When it happens

Trigger: Writing #[editor_commands(SomeArg)] or an attribute-value form on the commands module.

Common situations: Trying to configure the macro per module (naming, scoping, feature flags) when it supports no options; autocomplete inserting parentheses with a placeholder argument.
