Prompt guide

Good prompts name the thing, the style, and the use:

Fantasy shop panel · hand-painted, gold trim, dark wood · Roblox mobile UI, 4 item slots

• Put the game genre first: “cozy farm”, “sci-fi shooter”, “obby”.
• Name colors and materials, not adjectives like “cool” or “nice”.
• For packs, list items: “sword, shield, bow, potion, key”.
• Use Style Lock once you get a result you love to keep the rest consistent.

Chuni MCP

Let your coding agent generate assets directly into your project. Create a key in Studio → Settings → API keys, then:

claude mcp add chuni -e CHUNI_API_KEY=chuni_xxx -- npx -y @chuni/mcp

Cursor, Windsurf and other MCP clients use the same command and environment variable.

Tools your agent gets:

• chuni_generate_asset: generate and save files into your project (default assets/chuni/)
• chuni_get_generation: check on or download an earlier generation
• chuni_list_generations: your recent work
• chuni_account: plan, credits and costs

Then ask your agent: Add a matching health bar and coin icon to the HUD.

REST API

Use an API key as a bearer token. Generations run asynchronously; poll until status is completed.

POST /api/chuni/generate
Authorization: Bearer chuni_xxx
Content-Type: application/json

{ "prompt": "neon ability icons", "kind": "icon", "engine": "unity", "count": 4 }
→ { "id": "abc123", "status": "queued", "cost": 200, "credits": 14800 }

GET /api/chuni/v1/generations/abc123
→ { "generation": { "status": "completed", … }, "files": ["/api/files/…?token=…"] }

GET /api/chuni/v1/generations?limit=20
GET /api/chuni/v1/me

File links expire after a few minutes; fetch the generation again for fresh ones. Failed generations are refunded.
