A tool's message: what the history entry its change makes is for (the command's -m).
export const message = { type: "string", description: 'what this change is for, kept with its history entry and shown as its title: a line saying what and why ("Forge: avatars on history entries, so authors are known at a glance"), then more after a blank line if it needs it. Give one for each change that\'s a step of its own', }
