# Dream Loop Skill

An autonomous process for building extremely impressive visuals, especially 3D
scenes (games, apps, usually browser three.js/WebGL): generate photorealistic
concept art of the ideal result, build it, screenshot the live build, have a
judge score screenshot vs concept against a gated ladder, and iterate until
convergence. Goal: the most visually stunning result at an acceptable frame
rate for the target platform (e.g. 60 fps browser, 120 fps modern mobile).

This skill does NOT cover general web-app functionality, 2D UI design, or
non-visual quality, only the visual-fidelity loop.

## When to Use

- User says "dream loop" or asks for a game/scene/app built to a very high
  level of graphical fidelity.
- Follow-up refinement passes on an existing visual product (see Follow-up
  loops below).

## Prerequisites

- **Concept art**: the `image_generate` tool. If unavailable, stop and ask the
  user for a concept image (or an image-generation API to connect to).
- **Screenshots**: `browser_exec`, serve the build locally
  (`python3 -m http.server` for static builds), then `new_tab(url)`,
  `wait_for_load()`, `capture_screenshot()`.
- **Judging**: `vision_analyze` (see Judge section for the one-image-per-call
  workaround).
- **Optional**: Blender for asset modeling, see the `blender-3d-automation`
  skill. `delegate_task` for parallel asset work and fresh-context judging.

If you don't have the tools needed for the full loop, flag that to the user
early and stop.
