Qiaomu Codex Imagegen

Qiaomu Codex ImageGen

Codex ships an image generator that other agents cannot call. This package relays to it (codex app-server) and adds the craft that makes the pictures usable: a library of 24 templates (48 presets) distilled from 689 reference prompts, Mondo poster techniques, scenario presets, and a rule set for facts, text and identity.

How to call it

1. MCP tools present (suggest_directions, compose_prompt, generate_image, search_prompts, get_prompt, build_prompt, list_catalog; in Claude Code mcp__qiaomu-codex-imagegen__*): use them.
2. No MCP: run the CLI from this skill's folder: node scripts/cli.mjs suggest|compose|generate|search|prompt|list (see --help).
3. Neither available: tell the user to install (README). Requires the Codex CLI, logged in. Never fake an image with code.

The workflow: suggest, choose, compose, generate, check

1. Intake (no tool call yet)

Extract: topic, deliverable (what it is for), ratio, text mode, facts that must be exact, references and the role of each (identity person, product real packaging, style, layout), must-keep, must-avoid.

• Text mode: none (no text), exact_short (only the short text you list), typeset_later (text-free base with room for the title).
• Posters, covers, cards and slides need a typographic layer. A finished poster has a hierarchy: headline, subtitle, one or two info lines, a small tag. With only a headline, or none, the result is concept art, not a poster. So for these deliverables use exact_short and give a complete short copy set: headline plus copy as lines separated by ｜. Take the lines from the user's facts. If they gave none, ask, or write clearly fictional sample lines and say so; never invent real prices, dates of real events, names, statistics.
• none fits portraits and photos (T09–T11), product macros that carry no information, and base images the user will typeset. Keep every string short and read the result: models misspell, especially long Chinese.
• Ask only blocking questions, at most three: a missing subject, a real person's identity reference, or facts that must appear. Fill low-risk gaps with a stated default.

2. Suggest at least four divergent directions

Call suggest_directions with the topic, deliverable and any headline/text mode. It returns four or more directions with different visual mechanisms (typography-led, graphic structure, photographic, product macro, material/space, plus a Mondo artist option for poster-like work). Never mix two mechanisms into one image.

Present them to the user briefly, one numbered item each:

• name and template id,
• one concrete sentence of what this topic would look like in that mechanism (write it yourself from mechanism and the topic, not a copy of the lock text),
• what you still need from them (subject, data, reference photo),
• look at one references[].image thumbnail per direction when available, so your sentence matches the real look.

Then ask which to make: one, several, "all", or "你定". Offer to exclude these and propose more (exclude).

Skip the question when the user already fixed the style ("用 Mondo 风格", "T03", "就这个风格") or said to go ahead ("直接出", "你定"). For "你定", pick the two best-fitting directions from different families and say which and why.

3. Compose the prompt

For each chosen template direction call compose_prompt with concrete variables:

• Map the topic to one visible silhouette, action or relation, and say how it connects to the topic. At most one main symbol and one cross-over action.
• Colours are roles (background, primary, accent, ink), not fixed hex values. Material belongs where the preset puts it; do not overlay noise on everything.
• No invented facts: prices, statistics, titles, names, dates, weather, quotes, QR codes, logos.
• missing_required non-empty → ask for exactly that. weak_variables → they still hold generic defaults, fill them first.
• Preset with structural_override → rewrite the prompt by hand: delete the base sentences the override replaces, keep no conflicting structure, then send the result as raw_prompt with the 避免：… line.
• Typographic templates with no text: tell the user the base image only satisfies the style after the title is typeset.
• Give copy as ｜-separated lines; when strings include dates or numbers, list them all so the whitelist matches exactly (or pass a full text_rule).

Mondo directions skip this step: generate_image { prompt, style: <artist>, preset: <video-cover|poster|…> }.
