lookdev-auto
When to Use
Use whenever "looks/feels right" is the success criterion and there's no cheap numeric metric — animation easing/timing, zoom/camera feel, color grade, layout/spacing, design params, render/encoder settings, prompt params. Use the automated counterpart to lookdev when there's no human to sit the loop.

Visual eval loop — let a vision/video model tune what only an eye can judge
When the target is "does this LOOK/FEEL right" (not a number you can minimize), a
vision model (image) or video-understanding model (motion/timing) can be the judge in
a tight optimize loop. Worked reference: the screenstudio-alternative skill (iteration.py)
(tuned zoom-animation feel via fal-ai/video-understanding).
Set a maximum rounds/variants/render time and provider cost cap before starting. Upload only authorized artifacts to an approved destination, retain the previous best and stop on invalid output or no meaningful improvement. The referenced iteration.py helper is not bundled. Two-round convergence and token savings are hypotheses, not measured guarantees.
