--- name: randallliuxin/background-map source: https://app.decimal.ai/s/randallliuxin-background-map@2/SKILL.md source_sha256: 354389f01e52 --- # Background Map Asset Use this skill for a runtime background, map base, parallax plate, fixed battle background, title illustration, or other fixed-viewport scenic asset. Do not use it for scene references, actors, foreground props, UI, or collision-bearing geometry. Background-map produces non-pixel-art scenic images only: do not request pixel art or use nearest-neighbor processing to imitate it. ## Invocation Accept one asset request matching the shared Asset Skill request schema in `.godotmaker/asset-runtime/schema/asset-skill-request.schema.json`. Require `asset_type` to be `background-map`. Run `standalone_validation.compile_and_validate()` before returning it. The runner checks the family binding and stable path at L0, the PNG at L1, the registered `single -> Texture2D` route at L2, and real headless Godot load plus Texture2D structure at L3/L4; it overwrites rather than trusts caller-supplied validation. It begins from the shared result schema and checker, then proves the result. This skill can be invoked directly or by an orchestrator; its request and result are identical in both cases. Do not read or write `ASSETS.md`, tags, stage state, generated manifests, or dispatch state. ## Source, Reference, and Provider Contract References are optional. With no references, generate from the brief. With one or more references, validate every declared local path is a readable image, preserve its `canonical`, `style`, or `screen` role, and send the actual image to the selected provider. A textual path, a prompt-only description, or a silently omitted reference is a failure. Resolve a request `res://` reference against the project root before provider dispatch, while retaining the request path and role in provenance. Providers receive the resulting local image path as an attachment, never the literal `res://` text. Use exactly the declared `provider` (`native`, `codex`, `gemini`, or `openai`). Do not substitute another provider. Read its provider document before source generation. If it cannot execute its declared image-attachment path for every reference, STOP with `validation.passed: false` and create no final runtime asset. For Codex, the source report must include this exact auditable trace shape: ```json { "provider_trace": { "provider": "codex", "coding_model": "", "reasoning": "", "tool_call_id": "", "image_model_identity": "runtime_reported|not_exposed_by_subscription_runtime", "referenced_image_paths": [""] } } ``` When `image_model_identity` is `runtime_reported`, include non-empty `image_model`. Do not substitute a generated-path string, a prose explanation, or a role-only record for this trace. For every attempt, retain these project-local records under `.godotmaker/asset-generation/`: 1. `prompts/.txt` with the fixed viewport, target aspect and orientation, scene role, viewpoint, layer responsibility, style language, reference roles, and invariants to preserve. 2. `sources/_source.png`, the unmodified provider or user source. 3. `reports/_source.json`, recording provider, model, reasoning where the runtime exposes it, real reference attachments with roles, source path, and provider trace or failure. 4. `reports/_finalize.json`, the deterministic finalization report. 5. `reports/_validation.json`, written by the validation runner on a fully passing ladder. Do not edit it; run validation again after any regeneration. The visual source may only be a selected provider output or a user-provided source/reference. Never create art with Pillow, System.Drawing, ImageMagick, SVG, canvas, Godot drawing, inline scripts, color blocks, placeholders, or fake atlases/animations. Project-owned deterministic tools may only process an existing real image. ## Produce 1. Use the brief and actual style or screen references to establish the scene role, viewpoint, target aspect, orientation, layer responsibility, and non-pixel-art style language. 2. Generate a source image with no gameplay actors, pickups, hazards, UI, labels, logos, watermarks, or text. 3. Run the existing deterministic finalizer; do not reimplement it: ```bash python tools/asset_image_finalize.py \ --source .godotmaker/asset-generation/sources/_source.png \ --out assets/generated/background-map//.png \ --label \ --require-aspect \ --resize \ --report .godotmaker/asset-generation/reports/_finalize.json ``` The source aspect must pass before resizing. On failure, keep the attempt incomplete and do not claim readiness. 4. Keep the raw source, final PNG, provider report, and finalize report as provenance. The orchestrator derives its stable `source_layout: single` and `godot_artifact: Texture2D` handoff from this result; this Skill never writes manifests itself. 5. Verify that Godot can import and load that PNG as `Texture2D`. When `GM_EVAL_GODOT_PATH` or `GODOT_BIN` is configured, invoke that exact executable; otherwise invoke the project-configured `godot` command. Godot's normal PNG import is the native resource path for this family; do not create a redundant `.tres` merely to wrap the image. ## Result Return the shared generic result with one `runtime` output: ```json { "asset_type": "background-map", "outputs": [{ "role": "runtime", "name": "", "path": "res://assets/generated/background-map//.png", "godot_type": "Texture2D" }], "sources": [{ "path": "res://assets/generated/background-map//.png", "layout": "single" }], "previews": [], "validation": { "passed": true, "levels": {"L0": true, "L1": true, "L2": true, "L3": true, "L4": true} } } ``` Use the requested stable asset id in every path. A failed aspect, import, or load check must return `validation.passed: false` with an explanatory note; never claim a failed background is ready. Provider/reference failure must return the same failed result with no runtime output. Emit that generic result JSON directly as the final response, including for a STOP. Do not write `ASSET_RESULT.json`, a manifest, or a linked result file in place of returning the JSON: direct callers consume the response itself.
