Generic example for creating or updating a Codex skill with appropriate resources, metadata, validation, and forward-testing. Use for generic skill creator, create a skill, update a skill, skill creator, skill authoring, SKILL.md, agents/openai.yaml, init_skill.py, quick_validate.py, forward-test a skill, progressive disclosure and bundled resources. Use when the task needs to create a new Codex skill, update an existing skill, validate a skill folder, generate agents/openai.yaml metadata and forward-test a skill with subagents.

Generate original one-ink or controlled two-ink editorial images from any theme, sentence, article idea, object, or reference photo. Always use this skill when the user asks for 单色海报、双色印刷、单色调视觉、蓝色/绿色孔版印刷、risograph、网点照片、复古或当代编辑排版、zine poster, monochrome editorial poster, duotone print, or asks to use the mono-color style. It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.
