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):

- If the current runtime exposes a native image tool (e.g., Codex imagegen, Hermes image_generate), use it. Runtime-native tools are preferred by default — agents that know their own tool inventory should surface the native one here. - 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.

1. If none are available, tell the user and ask how to proceed.

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.

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", "不用確認", "跳過確認", "按默認出圖", 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

Combine freely: --type infographic --style vector-illustration --palette macaron

Or use presets: --preset edu-visual → type + style + palette in one flag. See Style Presets.

Workflow

- [ ] Step 1: Pre-check (EXTEND.md, references, config)
- [ ] Step 2: Analyze content
- [ ] Step 3: Confirm settings (AskUserQuestion)
- [ ] Step 4: Generate outline
- [ ] Step 5: Generate images
- [ ] Step 6: Finalize

Step 1: Pre-check

1.5 Load Preferences (EXTEND.md) ⛔ BLOCKING

Check EXTEND.md in priority order — the first one found wins:

Full procedures: references/workflow.md

Step 2: Analyze

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.

Full procedures: references/workflow.md

Step 4: Generate Outline

Save outline.md with frontmatter (type, density, style, palette, image_count) and entries:

## Illustration 1
**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.

1. For each illustration, create a prompt file per 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.
7. Execution strategy: When multiple illustrations have saved prompt files and the task is now plain generation, prefer the chosen backend's batch interface (if it offers one) over spawning subagents. Use subagents only when each image still needs separate prompt iteration or creative exploration. If the backend has no batch interface, generate sequentially.
8. Process references (direct/style/palette) per prompt frontmatter
9. Apply watermark if EXTEND.md enabled
10. Generate from saved prompt files; retry once on failure

Full procedures: references/workflow.md

Step 6: Finalize

Insert ![description]({relative-path}/NN-{type}-{slug}.png) 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):

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.

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. - 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.
