compile-prompt-i2i

Overview

Compiles a structured asset brief into a backend-specific prompt for i2i_iteration or i2i_reconstruction_input. The brief remains the source of truth; this skill only translates it.

When to Use

• When asset-generation-brief selects backend target i2i_iteration or i2i_reconstruction_input.
• During asset-gacha-session candidate generation.
• When repairing a candidate for this backend.

Compilation Focus

preserve/changing fields, mutation operators, avoid total redesign, and explicit reconstruction repair 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: i2i_iteration | i2i_reconstruction_input
prompt: ""
negative_prompt: ""
metadata_patch:
  compiler_skill: compile-prompt-i2i
  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 i2i_iteration or i2i_reconstruction_input.

Reconstruction Input Repair Contract

For i2i_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 source image has transparent glass, translucent shells, fire, smoke, particles, hologram-only surfaces, liquid mist, hair/fur/cloth strands, or other reconstruction-hostile features and the brief does not explicitly request opaque/solid repair.

Allowed repair directions include opaque rubbery jelly, solid painted goo, opaque crystal-like plastic, painted/emissive texture accents, and chunky opaque modules. The prompt must remove scene/background context and request a single complete centered object on a neutral gray or light gray solid background, with no text, logo, watermark, UI, or diorama.

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 i2i_iteration or i2i_reconstruction_input
• Preserves brief fields
• Includes hard anchors and selected style kit
• Includes backend-specific constraints
• Reconstruction input repair 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
