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):
- Prefer built-in user-input tools exposed by the current agent runtime — e.g.,
AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
- 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.
- 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:
- Current-request override — if the user names a specific backend in the current message, use it.
- Saved preference — if
EXTEND.md sets preferred_image_backend to a backend available right now, use it.
- 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-imagine) unless the user has explicitly pinned a different preferred_image_backend.
- 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-imagine), use it.
- Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.
- 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, image_generate, baoyu-imagine) 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:
- 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.
- 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.
- 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 (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-imagine accepts ref per task).
Three Dimensions
| Dimension | Controls | Examples |
|---|
| Type | Information structure | infographic, scene, flowchart, comparison, framework, timeline |
| Style | Rendering approach | notion, warm, minimal, blueprint, watercolor, elegant |
| Palette | Color scheme (optional) | macaron, warm, neon — overrides style's default colors |
Combine freely: --type infographic --style vector-illustration --palette macaron
Or use presets: --preset edu-visual → type + style + palette in one flag. See Style Presets.
Types
| Type | Best For |
|---|
infographic | Data, metrics, technical |
scene | Narratives, emotional |
flowchart | Processes, workflows |
comparison | Side-by-side, options |
framework | Models, architecture |
timeline | History, evolution |
Styles
See references/styles.md for Core Styles, full gallery, and Type × Style compatibility.

Step 1: Pre-check
1.5 Load Preferences (EXTEND.md) ⛔ BLOCKING
Check EXTEND.md in priority order — the first one found wins:
| Priority | Path | Scope |
|---|
| 1 | .baoyu-skills/baoyu-article-illustrator/EXTEND.md | Project |
| 2 | ${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-article-illustrator/EXTEND.md | XDG |
| 3 | $HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md | User home |

Step 2: Analyze
| Analysis | Output |
|---|
| Content type | Technical / Tutorial / Methodology / Narrative |
| Purpose | information / visualization / imagination |
| Core arguments | 2-5 main points |
| Positions | Where illustrations add value |
CRITICAL: Metaphors → visualize underlying concept, NOT literal image.
Full procedures: references/workflow.md
Step 3: Confirm Settings ⚠️
Hard gate: this step is mandatory per the Confirmation Policy — Steps 4+ cannot start until the user confirms here (or explicitly opts out with "直接生成" / equivalent wording in the current request).
ONE AskUserQuestion, max 4 Qs. Q1-Q2 REQUIRED. Q3 required unless preset chosen.
| Q | Options |
|---|
| Q1: Preset or Type | [Recommended preset], [alt preset], or manual: infographic, scene, flowchart, comparison, framework, timeline, mixed |
| Q2: Density | minimal (1-2), balanced (3-5), per-section (Recommended), rich (6+) |
| Q3: Style | [Recommended], minimal-flat, sci-fi, hand-drawn, editorial, scene, poster, Other — skip if preset chosen |
| Q4: Palette | Default (style colors), macaron, warm, neon — skip if preset includes palette or preferred_palette set |
| Q5: Language | When article language ≠ EXTEND.md setting |
Full procedures: references/workflow.md
Step 4: Generate Outline
Save outline.md with frontmatter (type, density, style, palette, image_count) and entries:
**Position**: [section/paragraph]
**Purpose**: [why]
**Visual Content**: [what]
**Filename**: 01-infographic-concept-name.png
Full template: references/workflow.md
Step 5: Generate Images
⛔ BLOCKING: Prompt files MUST be saved before ANY image generation. This is a hard requirement regardless of which backend is chosen — the prompt file is the reproducibility record.
- For each illustration, create a prompt file per references/prompt-construction.md
- Save to
prompts/NN-{type}-{slug}.md with YAML frontmatter
- Prompts MUST use type-specific templates with structured sections (ZONES / LABELS / COLORS / STYLE / ASPECT)
- LABELS MUST include article-specific data: actual numbers, terms, metrics, quotes
- DO NOT pass ad-hoc inline prompts to
--prompt without saving prompt files first
- 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.
- 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.
- Process references (
direct/style/palette) per prompt frontmatter
- Apply watermark if EXTEND.md enabled
- Generate from saved prompt files; retry once on failure
Full procedures: references/workflow.md
Step 6: Finalize
Insert  after paragraphs. Path computed relative to article file based on output directory setting.
Article Illustration Complete!
Article: [path] | Type: [type] | Density: [level] | Style: [style] | Palette: [palette or default]
Images: X/N generated
Output Directory
Output directory is determined by default_output_dir in EXTEND.md (set during first-time setup):
default_output_dir | Output Path | Markdown Insert Path |
|---|
imgs-subdir (default) | {article-dir}/imgs/ | imgs/NN-{type}-{slug}.png |
same-dir | {article-dir}/ | NN-{type}-{slug}.png |
illustrations-subdir | {article-dir}/illustrations/ | illustrations/NN-{type}-{slug}.png |
independent | illustrations/{topic-slug}/ | illustrations/{topic-slug}/NN-{type}-{slug}.png (relative to cwd) |
All auxiliary files (outline, prompts) are saved inside the output directory:
{output-dir}/
├── outline.md
├── prompts/
│ └── NN-{type}-{slug}.md
└── NN-{type}-{slug}.png
When input is pasted content (no file path), always uses illustrations/{topic-slug}/ with source-{slug}.{ext} saved alongside.
Slug: 2-4 words, kebab-case. Conflict: append -YYYYMMDD-HHMMSS.
Modification
| Action | Steps |
|---|
| Edit | Update prompt → Regenerate → Update reference |
| Add | Position → Prompt → Generate → Update outline → Insert |
| Delete | Delete files → Remove reference → Update outline |
Text correction policy:
- If any rendered text (labels, captions, etc.) is misspelled, garbled, hard to read, or visually weak, do not patch the bitmap with code.
- For text-correction regenerations, write a new prompt file and a new output path so the flawed candidate is preserved for comparison.
- Post-processing is limited to crop, resize, compression, or format conversion that does not alter text or the main composition.

Changing Preferences
EXTEND.md lives at the first matching path listed in Step 1.5. Three ways to change it:
- Edit directly — open EXTEND.md and change fields. Full schema:
references/config/preferences-schema.md.
- Reconfigure interactively — delete EXTEND.md (or ask "reconfigure baoyu-article-illustrator preferences" / "重新配置"). The next run re-triggers first-time setup.
- Common one-line edits:
preferred_image_backend: auto — default; runtime-native tool wins, falls back to the only installed backend, asks only if multiple non-native are present.preferred_image_backend: codex-imagegen — pin to Codex's built-in.preferred_image_backend: baoyu-imagine — pin to the baoyu-imagine skill.preferred_image_backend: ask — confirm backend every run.generation_batch_size: 4 — default number of images to render concurrently when the runtime supports parallel generation calls.preferred_type: infographic, preferred_style: notion, preferred_palette: macaron, language: zh.default_output_dir: imgs-subdir — where to write generated images relative to the article.
