 * MESSAGE commitment definition
 *
 * The MESSAGE commitment contains 1:1 text of the message which AI assistant already
 * sent during the conversation. Later messages are later in the conversation.
 * It is similar to `WRITING SAMPLE`, but it is not a sample. It is the real
 * message that the AI assistant already sent.
 *
 * Example usage in agent source:
 *
 * ```book
 * MESSAGE Hello! How can I help you today?
 * MESSAGE I understand you're looking for information about our services.
 * MESSAGE Based on your requirements, I'd recommend our premium package.
 * ```
 *
 * @private [🪔] Maybe export the commitments through some package
