What the source shows
Ubisoft describes writers defining character background and behavior, followed by iteration on how models respond within those constraints. The authoring work remains part of the system.
Supporting documentation (opens in a new tab)What to take into your own work
Start with one character, a specific scene and a limited objective. Test both a normal conversation and a request that contradicts the character’s knowledge or motivation.
What this does not establish
Ubisoft explicitly presents a prototype, not a feature shipped across its games. The page does not establish a current product subscription or a repeatable workflow for independent developers.
