10# Article Illustrator
11 
12Analyze articles, identify illustration positions, generate images with Type × Style × Palette consistency.
13 
14## User Input Tools
15 
16When this skill prompts the user, follow this tool-selection rule (priority order):
17 
181. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., `AskUserQuestion`, `request_user_input`, `clarify`, `ask_user`, or any equivalent.
192. **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.
203. **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.
21 
22Concrete `AskUserQuestion` references below are examples — substitute the local equivalent in other runtimes.
23 
24## Image Generation Tools
25 
26When this skill needs to render an image, resolve the backend in this order:
27 
281. **Current-request override** — if the user names a specific backend in the current message, use it.
292. **Saved preference** — if `EXTEND.md` sets `preferred_image_backend` to a backend available right now, use it.
303. **Auto-select** (when the preference is `auto`, unset, or the pinned backend isn't available):
31   - 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.
32   - Otherwise, if exactly one non-native backend is installed (e.g., `baoyu-imagine`), use it.
33   - Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.
344. **If none are available**, tell the user and ask how to proceed.
35 
36Setting `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.
37 
38**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.
39 
40Concrete tool names (`imagegen`, `image_generate`, `baoyu-imagine`) above are examples — substitute the local equivalents under the same rule.
41 
42## Confirmation Policy
43 
44Default behavior: **confirm before generation**.
45 
46- Treat explicit skill invocation, a file path, matched signals/presets, and `EXTEND.md` defaults as **recommendation inputs only**. None of them authorizes skipping confirmation.
47- Do **not** start Step 4 or later until the user completes Step 3.
48- 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.
49- If confirmation is skipped explicitly, state the assumed type / density / style / palette / language / backend in the next user-facing update before generating.
50 
51## Reference Images
52 
53Users 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.
54 
55Full 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-imagine` accepts `ref` per task).
56 
57## Three Dimensions
58 
59| Dimension | Controls | Examples |
60|-----------|----------|----------|
61| **Type** | Information structure | infographic, scene, flowchart, comparison, framework, timeline |
62| **Style** | Rendering approach | notion, warm, minimal, blueprint, watercolor, elegant |
63| **Palette** | Color scheme (optional) | macaron, warm, neon — overrides style's default colors |
64 
65Combine freely: `--type infographic --style vector-illustration --palette macaron`
66 
67Or use presets: `--preset edu-visual` → type + style + palette in one flag. See [Style Presets](references/style-presets.md).
68 
69## Types
70 
71| Type | Best For |
72|------|----------|
73| `infographic` | Data, metrics, technical |
74| `scene` | Narratives, emotional |
75| `flowchart` | Processes, workflows |
76| `comparison` | Side-by-side, options |
77| `framework` | Models, architecture |
78| `timeline` | History, evolution |
79 
80## Styles
81 
82See [references/styles.md](references/styles.md) for Core Styles, full gallery, and Type × Style compatibility.

84## Workflow
85 
86```
87- [ ] Step 1: Pre-check (EXTEND.md, references, config)
88- [ ] Step 2: Analyze content
89- [ ] Step 3: Confirm settings (AskUserQuestion)
90- [ ] Step 4: Generate outline
91- [ ] Step 5: Generate images
92- [ ] Step 6: Finalize
93```
94 
95### Step 1: Pre-check
96 
97**1.5 Load Preferences (EXTEND.md) ⛔ BLOCKING**
98 
99Check EXTEND.md in priority order — the first one found wins:
100 
101| Priority | Path | Scope |
102|----------|------|-------|
103| 1 | `.baoyu-skills/baoyu-article-illustrator/EXTEND.md` | Project |
104| 2 | `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-article-illustrator/EXTEND.md` | XDG |
105| 3 | `$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md` | User home |
106 
107| Result | Action |
108|--------|--------|
109| Found | Read, parse, display summary |
110| Not found | ⛔ Run [first-time-setup](references/config/first-time-setup.md) |
111 
112Full procedures: [references/workflow.md](references/workflow.md#step-1-pre-check)
113 
114### Step 2: Analyze
115 
116| Analysis | Output |
117|----------|--------|
118| Content type | Technical / Tutorial / Methodology / Narrative |
119| Purpose | information / visualization / imagination |
120| Core arguments | 2-5 main points |
121| Positions | Where illustrations add value |
122 
123**CRITICAL**: Metaphors → visualize underlying concept, NOT literal image.

126 
127### Step 3: Confirm Settings ⚠️
128 
129**Hard gate**: this step is mandatory per the [Confirmation Policy](#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).
130 
131**ONE AskUserQuestion, max 4 Qs. Q1-Q2 REQUIRED. Q3 required unless preset chosen.**
132 
133| Q | Options |
134|---|---------|
135| **Q1: Preset or Type** | [Recommended preset], [alt preset], or manual: infographic, scene, flowchart, comparison, framework, timeline, mixed |
136| **Q2: Density** | minimal (1-2), balanced (3-5), per-section (Recommended), rich (6+) |
137| **Q3: Style** | [Recommended], minimal-flat, sci-fi, hand-drawn, editorial, scene, poster, Other — **skip if preset chosen** |
138| Q4: Palette | Default (style colors), macaron, warm, neon — **skip if preset includes palette or preferred_palette set** |
139| Q5: Language | When article language ≠ EXTEND.md setting |

142 
143### Step 4: Generate Outline
144 
145Save `outline.md` with frontmatter (type, density, style, palette, image_count) and entries:
146 
147```yaml
148## Illustration 1
149**Position**: [section/paragraph]
150**Purpose**: [why]
151**Visual Content**: [what]
152**Filename**: 01-infographic-concept-name.png
153```
154 
155Full template: [references/workflow.md](references/workflow.md#step-4-generate-outline)
156 
157### Step 5: Generate Images
158 
159⛔ **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.
160 
1611. For each illustration, create a prompt file per [references/prompt-construction.md](references/prompt-construction.md)
1622. Save to `prompts/NN-{type}-{slug}.md` with YAML frontmatter
1633. Prompts **MUST** use type-specific templates with structured sections (ZONES / LABELS / COLORS / STYLE / ASPECT)
1644. LABELS **MUST** include article-specific data: actual numbers, terms, metrics, quotes
1655. **DO NOT** pass ad-hoc inline prompts to `--prompt` without saving prompt files first
1666. 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.
1677. **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.
1688. Process references (`direct`/`style`/`palette`) per prompt frontmatter
1699. Apply watermark if EXTEND.md enabled
17010. Generate from saved prompt files; retry once on failure
171 
172Full procedures: [references/workflow.md](references/workflow.md#step-5-generate-images)
173 
174### Step 6: Finalize
175 
176Insert `![description]({relative-path}/NN-{type}-{slug}.png)` after paragraphs. Path computed relative to article file based on output directory setting.
177 
178```
179Article Illustration Complete!
180Article: [path] | Type: [type] | Density: [level] | Style: [style] | Palette: [palette or default]
181Images: X/N generated
182```
183 
184## Output Directory
185 
186Output directory is determined by `default_output_dir` in EXTEND.md (set during first-time setup):
187 
188| `default_output_dir` | Output Path | Markdown Insert Path |
189|----------------------|-------------|----------------------|
190| `imgs-subdir` (default) | `{article-dir}/imgs/` | `imgs/NN-{type}-{slug}.png` |
191| `same-dir` | `{article-dir}/` | `NN-{type}-{slug}.png` |
192| `illustrations-subdir` | `{article-dir}/illustrations/` | `illustrations/NN-{type}-{slug}.png` |
193| `independent` | `illustrations/{topic-slug}/` | `illustrations/{topic-slug}/NN-{type}-{slug}.png` (relative to cwd) |
194 
195All auxiliary files (outline, prompts) are saved inside the output directory:
196 
197```
198{output-dir}/
199├── outline.md
200├── prompts/
201│   └── NN-{type}-{slug}.md
202└── NN-{type}-{slug}.png
203```
204 
205When input is **pasted content** (no file path), always uses `illustrations/{topic-slug}/` with `source-{slug}.{ext}` saved alongside.
206 
207**Slug**: 2-4 words, kebab-case. **Conflict**: append `-YYYYMMDD-HHMMSS`.
208 
209## Modification
210 
211| Action | Steps |
212|--------|-------|
213| Edit | Update prompt → Regenerate → Update reference |
214| Add | Position → Prompt → Generate → Update outline → Insert |
215| Delete | Delete files → Remove reference → Update outline |

228## Changing Preferences
229 
230EXTEND.md lives at the first matching path listed in Step 1.5. Three ways to change it:
231 
232- **Edit directly** — open EXTEND.md and change fields. Full schema: `references/config/preferences-schema.md`.
233- **Reconfigure interactively** — delete EXTEND.md (or ask "reconfigure baoyu-article-illustrator preferences" / "重新配置"). The next run re-triggers first-time setup.
234- **Common one-line edits**:
235  - `preferred_image_backend: auto` — default; runtime-native tool wins, falls back to the only installed backend, asks only if multiple non-native are present.
236  - `preferred_image_backend: codex-imagegen` — pin to Codex's built-in.
237  - `preferred_image_backend: baoyu-imagine` — pin to the baoyu-imagine skill.
238  - `preferred_image_backend: ask` — confirm backend every run.
239  - `preferred_type: infographic`, `preferred_style: notion`, `preferred_palette: macaron`, `language: zh`.
240  - `default_output_dir: imgs-subdir` — where to write generated images relative to the article.
