Return the guidelines for composing and animating SVGs. Read this before generating an animation. Pass a style (a preset key like "minimal-modern" or a freeform phrase like "minimalistic but modern") to also get concrete art direction for that look.

List the built-in animation style presets. You can also pass any freeform style phrase to create_animation/get_best_practices.

Render a self-contained animated SVG in the local preview UI and open it in the browser. First compose the scene as a layered SVG with an explicit viewBox, then animate it with CSS @keyframes (or SMIL) embedded in the SVG, using natural easing. Call get_best_practices (optionally with a style) first if you need the full guidance. Pass the same style you designed for so it is recorded and shown. The svg argument must be a complete ... document that animates on its own with no external assets or scripts.

List animations created this session, newest first.

Long-poll for the next change the user typed into the preview UI's chat box. This is how live edits work: call it, and it blocks until a request arrives (or ~25s passes). When it returns an edit, apply the change FAST: for small tweaks (color, size, position, timing, text, easing) call apply_patch with minimal find/replace edits — do NOT regenerate the whole SVG. Use apply_edit (full SVG) only for structural changes. Then call await_edit_request again to keep watching. When it returns 'idle', simply call it again. Keep this loop running while the user iterates.

Apply a regenerated SVG to the animation referenced by an edit request (from await_edit_request). Updates the animation in place — the preview UI refreshes live. Pass the complete new .

Apply small find/replace edits to an animation's SVG in place — the fast path for tweaks like color, size, position, timing, text, or easing. Prefer this over apply_edit: it avoids resending the whole document. Each find must match the current SVG exactly (verbatim substring). If a find isn't found, the patch is rejected wholesale (nothing changes) — fix the find or fall back to apply_edit. The preview refreshes live.

Ensure the preview web server is running and open it in the browser.
