Use this skill whenever a user asks to generate, create, draw, render, or edit images with GPT Image 2 / gpt-image-2, text-to-image, reference-image editing, inpainting, posters, typography, Chinese text, UI mockups, diagrams, or gallery prompts. Analyze the user's prompt, search the bundled Reference Gallery/craft files for matching design patterns, confer on direction when useful, then call the bundled CLI script directly. Do not write new image-generation code unless explicitly asked to modify this repo.
READ this skill when designing or planning any game system architecture — including combat, skills, AI, UI, multiplayer, narrative, or scene systems. Contains paradigm selection guides (DDD / Data-Driven / Prototype), system-specific design references, and mixing strategies. Works as a domain knowledge plugin alongside workflow skills (OpenSpec, SpecKit) or plan mode of an agent.
Inspect the repo state and recommend the next step in the simplified workflow.
Run the full design pipeline with brainstorm wizard, or add one missing system.
READ this skill when implementing or configuring animation-style shaders (Toon/Cel Shaders) — including outlines, rim lighting, toon shading, MatCap, emission, dissolve, hatching, or any stylized rendering effect. Contains preset styles and feature-to-reference mappings for lilToon, Poiyomi, UTS2, RToon, SToon, and ToonShadingCollection. Works as a domain knowledge plugin alongside workflow skills (OpenSpec, SpecKit) or plan mode of an agent.
Break the project into milestones and create production/milestone.md plus milestone directories.

This skill implements one task at a time from tasks.md.
If argument is a milestone directory or id:
tasks.mdStatus: ReadyIf argument is a task id like TASK-001:
production/milestone-*/tasks.mdIf no argument:
production/milestone-*/tasks.mdStatus: ReadyRead:
tasks.mddesign/gdd/game.mddesign/gdd/systems-index.md if existstech.mdIf task is missing acceptance criteria or files to touch, stop and say to refine with /gat-plan.
If milestone is missing tech.md, stop and say to run /gat-plan first.
Spawn gat-programmer agent with:
tasks.mdtech.mdThe programmer should edit the smallest useful set of files in src/ and tests/.
Summarize files changed, tests added, final task status.
