Unable to save the role with arguments (whose name contains…

Error message

Unable to save the role with arguments (whose name contains '#')

What it means

Raised by save_role() when the current role uses argument placeholders (its name/prompt contains '#' argument markers). Such roles are ephemeral by design; persisting a role with unresolved arguments would bake in invalid placeholders, so saving is refused. The input at fault is a role with has_args() true.

Solutions

1. Remove the argument placeholders from the prompt before saving
2. Save the role under a plain name without arguments and pass arguments at usage time
3. Use upsert_role with an explicit, argument-free definition instead
