Analyzes article structure, identifies positions requiring visual aids, generates illustrations with Type × Style × Palette three-dimension approach. Use when user asks to "illustrate article", "add images", "generate images for article", or "为文章配图".

Article Illustrator Analyze articles, identify illustration positions, generate images with Type × Style × Palette consistency. User Input Tools When this skill prompts the user, follow this tool selection rule (priority order): 1. Prefer built in user input tools exposed by the current agent runtime — e.g., AskUserQuestion , request user input , clarify , ask user , or any equivalent. 2. Fallback : if no such tool exists, emit a numbered plain text message and ask the user to reply with the chosen number/answer for each question. 3. Batching : if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single question, ask them one at a time in priority order. Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes. Image Generation Tools When this skill needs to render an image, resolve the backend in this order: 1. Current request override — if the user names a specific backend in the current message, use it. 2. Saved preference — if EXTEND.md sets preferred image backend to a backend available right now, use it. 3. Auto select (when the preference is auto , unset, or the pinned backend isn't available): Codex ( imagegen ) — first, inspect your available skills / tool inventory. If a skill named imagegen is listed, you are running inside Codex and MUST use it: invoke via the Skill tool with skill: "imagegen" , passing the saved prompt file's content (plus output path and aspect ratio per Codex imagegen 's own args). Codex imagegen is the official raster backend in that runtime and outranks any non native skill (e.g., baoyu image gen ) unless the user has explicitly pinned a different preferred image backend . Codex via codex exec ( codex imagegen ) — if the current runtime exposes no native imagegen skill but the codex CLI is on PATH with an active codex login , route through baoyu image gen provider codex cli (preferred), or — if baoyu image gen is unavailable — invoke the bundled wrapper directly. Details, parameters, and the runtime discovery procedure live in [references/codex imagegen.md](references/codex imagegen.md) — load that file only when this branch is selected. Cursor ( GenerateImage ) — if the runtime exposes a native GenerateImage tool, you are running inside Cursor and it outranks any non native skill the same way Codex imagegen does. Two hard caveats: (a) it has no aspect ratio parameter — state the target aspect ratio / dimensions explicitly in the prompt text passed as description ; (b) it does not accept an output directory — it saves to a tool managed location, so after generation copy/move the file to the skill's expected output path (e.g., outputs/.../NN xxx.png ). Reference images go in reference image paths . Other runtime native tools — if the runtime exposes a different native image tool (e.g., Hermes image generate ), use it the same way. Otherwise, if exactly one non native backend is installed (e.g., baoyu image gen ), use it. Otherwise (multiple non native backends with no runtime native tool), ask the user once — batch with any other initial questions. 4. If none are available , tell the user and ask how to proceed. ⛔ Never substitute SVG, HTML, canvas, or other code based rendering for raster image generation. Codex imagegen 's own description says it should be used "when the output should be a bitmap asset rather than repo native code or vector." If you cannot resolve a raster backend via step 3, fall through to step 4 and ask the user — do not silently emit SVG, write inline <svg markup, or produce HTML/CSS art as a substitute. This applies even if the article/section seems "diagram like": the consumer skill calling this rule has already decided that a raster image is what it needs. ⛔ Never repair rendered text by painting over a generated bitmap. Do not use ImageMagick, Pillow, Canvas, SVG, HTML/CSS, OCR scripts, or any other programmatic overlay to cover, rewrite, erase, stroke, or replace labels, captions, or any other text inside an already generated illustration. If text is wrong or unclear, regenerate from a corrected prompt, redraw with less or no on image text, or ask the user which imperfect candidate to keep. Setting preferred image backend: ask forces the step 3 prompt every run regardless of available backends. Users change the pinned backend via the Changing Preferences section below. Prompt file requirement (hard) : write each image's full, final prompt to a standalone file under prompts/ (naming: NN {type} [slug].md ) BEFORE invoking any backend. The backend receives the prompt file (or its content); the file is the reproducibility record and lets you switch backends without regenerating prompts. Concrete tool names ( imagegen , GenerateImage , image generate , baoyu image gen ) above are examples — substitute the local equivalents under the same rule. Batch Generation Policy After every prompt file for the run has been saved and verified, generate images in batches by default. Priority order: 1. Use the chosen backend's native batch / multi task interface if it exists. Each task must keep its own prompt file, output path, aspect ratio, and direct reference images. 2. If no native batch interface exists but the runtime can issue parallel tool calls, dispatch up to generation batch size images at a time. Default: 4 . An explicit user request in the current message, such as batch size 4 or "并行4张一起生成", overrides EXTEND.md. 3. If neither native batch nor parallel tool calls are available, generate sequentially. Rules: Never start the first batch until all prompt files for that batch exist on disk. Retry failed items once without regenerating successful items. Do not use subagents merely to parallelize image rendering. Use subagents only for separate prompt iteration or creative exploration. Confirmation Policy Default behavior: confirm before generation . Treat explicit skill invocation, a file path, matched signals/presets, and EXTEND.md defaults as recommendation inputs only . None of them authorizes skipping confirmation. Do not start Step 4 or later until the user completes Step 3. Skip confirmation only when the current request explicitly says to do so, for example: "直接生成", "不用确认", "跳过确认", "按默认出图", or equivalent wording. If confirmation is skipped explicitly, state the assumed type / density / style / palette / language / backend in the next user facing update before generating. Reference Images Users may supply reference images via ref <files... or by providing file paths / pasting images in conversation. Refs guide style, palette, composition, or subject for specific illustrations. Full detection, storage, and processing rules are in [references/workflow.md](references/workflow.md) (Step 1.0 saves to references/NN ref {slug}.{ext} ; Step 5.3 processes per illustration usage direct style palette ). When the chosen backend supports batch input, direct usage entries in each prompt file's references: frontmatter should be propagated into its batch payload so backends can pass them through (e.g. baoyu image gen accepts ref per task).

This is a hard requirement regardless of which backend is chosen — the prompt file is the reproducibility record. 1. For each illustration, create a prompt file per [references/prompt construction.md](references/prompt construction.md) 2. Save to prompts/NN {type} {slug}.md with YAML frontmatter 3. Prompts MUST use type specific templates with structured sections (ZONES / LABELS / COLORS / STYLE / ASPECT) 4. LABELS MUST include article specific data: actual numbers, terms, metrics, quotes 5. DO NOT pass ad hoc inline prompts to prompt without saving prompt files first 6. Select the backend via the Image Generation Tools rule at the top: use whatever is available; if multiple, ask the user once. Do this once per session before any generation. codex imagegen invocation : when the rule resolves to codex imagegen , see [references/codex imagegen.md](references/codex imagegen.md) for the invocation contract (preferred baoyu image gen provider codex cli path, runtime wrapper discovery, parameter notes, stdout schema, batch semantics). 7. Execution strategy : Generate in batches per the Batch Generation Policy : backend native batch first, runtime parallel tool calls second, sequential only as fallback. Default batch size is 4 unless EXTEND.md or the current request overrides it. 8. Process references ( direct / style / palette ) per prompt
