Two tools with minimal definitions. Echo has a trivial description (34 chars, at baseline minimum) and a single string parameter with a misleading description ('Message for the email' when the tool echoes input). SendEmail has a basic description (32 chars) but critical gaps: no parameter descriptions for 'person' or 'message', no output schema documentation, no error handling guidance, and no indication that it performs a destructive operation (sends email). Neither tool declares input constraints, enums, or validation rules. No pagination, no idempotency markers, no recovery guidance. Schemas are inferred from C# attributes rather than explicitly visible in JSON Schema format.

• Add explicit parameter descriptions to SendEmail: 'person' should describe valid identifiers (e.g., 'Recipient identifier: one of example, aFriend') and 'message' should describe the email body content.
• Update Echo's parameter description from 'Message for the email' to 'Text to echo back to the client' to match the tool's actual behavior.
• Document SendEmail's output schema: specify that it returns a CallToolResponse with a Content array containing a text field with the message 'Message Sent'.
• Add error handling to SendEmail: catch KeyNotFoundException when 'person' is not found and return a recovery message like 'Person not found. Valid recipients: example, aFriend'.
• Declare SendEmail as a destructive operation in its description: 'Sends an email to a recipient. This action is irreversible and will be delivered immediately.'
