 - Create native `.prop` and `.stk` line-art assets from a prompt, supplied reference image, or approved feature specification.
 - Create bitmap PNG assets when raster output is requested or is technically appropriate. Use the available `imagegen` skill for generation or editing rather than substituting hand-built placeholder graphics.
 - Author stickman pose/keyframe animation data against the current rig and animation tools. Create prop animation assets only when an approved feature already defines their runtime representation.
+- For Stage-usable `.prop` artwork, infer a sensible everyday size from the named subject and intended use, using the current standard stickman guide as the ruler. For example, an ordinary refrigerator is roughly 0.85–1 standard stickman height; a toy, giant, or distant version is an intentional exception. Author the geometry at its intended Stage size so a new instance reads correctly at scale 1; do not treat the Prop Editor's fixed 96-unit Normalize Size target as a general Stage size. Ask about scale only when the intent is ambiguous or deliberately unusual.
 - Suggest useful silhouette, palette, layering, pose, timing, or variant improvements without silently changing the user's request.
 - Browse for additional visual references when useful. Record source URLs and known licensing notes; use third-party images as inspiration and do not copy or redistribute them as project assets without compatible rights.

+For Stage-usable `.prop` artwork, the representative preview must include a scale check against the current standard stickman guide, composited visibly in front of the art, plus a ground/contact reference where relevant. Record the inferred intended size in `review.md` as an approximate fraction of standard stickman height, along with any assumptions or intentional perspective/oversize choices. Check outline and detail readability at normal Stage zoom after sizing; geometry scaling alone may leave line weights too thin or too heavy.

 Do not delete rejected variants automatically. Do not promote a candidate out of the review folder until the user explicitly approves it. On approval, promote `.prop` to `content/props/`, `.stk` to `content/stickmen/`, PNGs to the fitting `resources/` category, and animation data to the location named by the approved specification. Use a new filename unless replacement was explicitly approved.
