compile-prompt-t2i

Overview

Compiles a structured asset brief into a backend-specific prompt for t2i_concept or t2i_reconstruction_input. The brief remains the source of truth; this skill only translates it.

When to Use

• When asset-generation-brief selects backend target t2i_concept or t2i_reconstruction_input.
• During asset-gacha-session candidate generation.
• When repairing a candidate for this backend.

Compilation Focus

concept mood, silhouette, material, style tension, role readability, output composition, and reconstruction source-image constraints when selected.

Prompt Assembly Order

1. State asset type and game context.
2. Insert hard/soft anchors from asset-prompt-core.
3. Insert asset role and player-read.
4. Insert style-kit route and tension dials.
5. Insert creative aperture and lineage fields.
6. Insert backend-specific constraints.
7. Insert output request.
8. Insert negative prompt.

Required Output

backend_profile: t2i_concept | t2i_reconstruction_input
prompt: ""
negative_prompt: ""
metadata_patch:
  compiler_skill: compile-prompt-t2i
  required_checks: []

Backend-Specific Checks

• t2i_concept: multiple distinct compositions allowed; no vague "make it cool".
• t2i_reconstruction_input: require explicit primary_style_goal and style kit; single centered complete object; neutral gray or light gray solid background; no scene, diorama, text, logo, watermark, transparent glass, translucent shell, volumetric smoke, fire/flame-only detail, particle-only form, or hologram-only surface; use a 3/4 primary view with mild orthographic/product-shot feel; prefer thick opaque forms, clear pivot, and socketable modules.
• i2i_iteration: explicitly list PRESERVE and MUTATE fields.
• i2i_reconstruction_input: preserve selected source strengths while enforcing the reconstruction input contract; block unless hostile source features have explicit opaque/solid repair instructions.
• icon_ui: require 32px/64px readability and no fake text.
• vfx_texture: require gameplay phase and occlusion budget.
• material_tile: require one material read and tile/reuse constraints.

Use only the checks relevant to t2i_concept or t2i_reconstruction_input.

Reconstruction Input Contract

For t2i_reconstruction_input, block the brief instead of compiling when:

• primary_style_goal is missing.
• style_kit or an equivalent style-kit route is missing.
• the requested asset depends on transparent glass, translucent membranes, fire, smoke, particles, holograms, liquid mist, hair/fur/cloth strands, many tiny legs, or other reconstruction-hostile detail.

When valid, the prompt must still describe the game style: pixel-first hyperreal cute-tech, dark-neon readable game asset, cute arcade pixel readability, and Godot no-rig modular asset friendliness. Do not turn that style into an environment scene.

Common Pitfalls

1. Adding new art direction not present in the brief.
2. Omitting negative prompt.
3. Using the same prose for all backends.

Verification Checklist

• Uses backend profile t2i_concept or t2i_reconstruction_input
• Preserves brief fields
• Includes hard anchors and selected style kit
• Includes backend-specific constraints
• Reconstruction input prompts require style, plain neutral background, one complete centered object, no scene/text/logos, and opaque/solid material boundaries
• Emits prompt, negative_prompt, and metadata_patch
