ALT Say who owns the code Claude Fable 5.2 responds closely to what the prompt says about who owns the code it works on. In Anthropic’s testing on small coding tasks, when a prompt said nothing about ownership or presented the code base as someone else’s, the model tended to add to the existing structure, even when that repeated existing code. It also tended to report nearby problems instead of fixing them. When the prompt says the code base is the model’s own, the model often merges repeated code and makes related fixes without being asked. If you want the model to improve the structure as it works, say that the code is its own: This codebase is yours: what it's for and how it's built are your call, and you'll keep building on it. In Anthropic’s testing on small coding tasks, the model merged repeated code in about half of the tries with this sentence, and in under a tenth of the tries without it. The rate varied by task. The result held when the sentence stood inside a long system prompt

ALT Screenshot of a mobile 3D voxel-style game: a first-person view from the saddle of a small teal dragon, its neck with pale diamond markings and two curved white horns in the foreground, flying toward a dark stone castle with tall teal-gray conical spires, glowing windows and teal pennants, set on a rocky island in a lake with green and snowy hills behind. Top bar: profile icon, "keep it", "your den" dropdown, "+ new game" button and a "..." menu. Right side: icon buttons and a portrait of a white-haired, freckled character labeled "tap to talk". Bottom right buttons: "JUMP" and "USE".

ALT Screenshot of the same game with the chat panel open over the castle scene. Top bar: "your den" dropdown, "+ new game". Button: "earlier ↑". User message: "Make the dragon smaller and land it next to me again". Replies from the white-haired character: "on it. shrinking it to a pony-sized dragon and landing it right beside you." Then: "it's a little dragon now and you're already up on it over the lake. your view sits right in its saddle, horns ahead. fly back to the house and look down. saw your screen just now: flying over the water, the neck and horns ahead, the house on the far shore" Then: "oh, idea: USE while flying could breathe fire instead, with JUMP held to land. want it?" Input box: "what do you want to bring in?" Buttons below: upload, a small pixel-art icon, "lock in" and a microphone.
