An agent skill that builds a game, app, or scene with impressive visuals, by creating a closed loop:
- AI "dreams" up a high-quality target screenshot using image generation
- AI builds with this target in mind
- A separate AI critic compares the live screenshot to the target and provides feedback
- AI loops back to step 2 until critic is satisfied
- Optionally, AI loops back to step 1 and dreams up an even better target based on the current state.
npx skills add achimala/dream-loop, or clone into your agent's skills directory, or paste the link into your agent and tell it to figure it out.
You need an AI agent with:
- access to image generation, either built-in (e.g. Codex, Grok) or via API (e.g. give it a Gemini API key)
- vision input
- subagents (optional but strongly preferred)
Install Blender if you want custom 3D modeling. The Blender MCP or scripting interface is preferred to computer use; it produces better results.
At the moment this is only tested with GPT-6 Astra in Codex. Other strong models like Claude Fable 5.1 can likely work too.
Prompt:
Build me a graphics demo: isometric camera, voxel-ish art style with realistic shading and reflective wet floors, a character in an interesting scene. Fantasy setting (think Elden Ring, Diablo). Three.js in browser, >60fps. Don't download assets. Time limit of 1 hour. Controls: click to move the character, camera lazy-follows; drag to rotate camera; scroll to zoom in/out. No gameplay for now. World should feel alive: motion, animations, subtle environmental behaviors. Area around player should look expansive, but only allow movement in a limited space. No need to confirm the art with me or ask questions, just go!

I'd love to hear feedback, see results, and accept edits to the skill.
If you open a PR, please provide example results produced by the skill, to ensure the changes don't regress performance.
