Finding

The manifest description lists broad invocation examples such as 'create an invoice', 'add a new customer', and 'send this invoice' without explicit scope limits or negative examples. In a manifest file, these generic phrases can overlap with ordinary conversation and make it unclear when this specific skill should activate versus other finance or CRM-related skills.
