# Make tweakable Make sure your design supports Tweaks. If the user tells you what to make tweakable, do that. If not, pick a few high-impact values — key colors, a layout variant, a feature flag, headline copy. Keep the Tweaks panel small and tasteful; hide it completely when Tweaks is off.

Timeline-based motion design
Runtime capabilities a published Artifact page can be granted — behavior static HTML cannot provide on its own, such as the page reading live or connected data, remembering what people do on it (a poll, a sign-up sheet, a checklist, a document edited in place — it saves new versions of itself), keeping state shared across viewers, knowing who is viewing, asking Claude a question of its own, storing files people add, or handing the viewer a file to save. Serves this user's live capability roster and the typed call definitions. Load it whenever the user asks for an artifact needing any such runtime behavior.
Design guidance and fundamentals for Artifacts.
Diagramming know-how for Artifacts - when a picture earns its place, how to draw one that shows the real mechanism, and the inline-SVG mechanics that keep it legible in both themes.
Research and plan a large-scale change, then execute it in parallel across 5–30 isolated worktree agents that each open a PR.
