 ## Workflow

-### Step 1: Analyze Content & Determine Scope
+### Step 1: Analyze Content

 1. Read source content
-2. If `--style` specified, use it; otherwise auto-select
-3. If `--layout` specified, use it; otherwise auto-select per page
-4. Determine page count based on content complexity:
+2. Select style (from `--style` or auto-detect)
+3. Select layout (from `--layout` or auto-detect per page)
+4. Determine page count:
+   - Short story: 5-8 pages
+   - Medium complexity: 9-15 pages
+   - Full biography: 16-25 pages

-| Content Type | Page Count (incl. cover) |
-|-------------|--------------------------|
-| Single event / short story | 5-8 |
-| Medium complexity / mini biography | 9-15 |
-| Full biography / multi-thread | 16-25 |
+### Step 2: Define Characters

-### Step 2: Generate Outline
+**Purpose**: Establish visual consistency across all pages.

-Plan cover + each page with detailed panel breakdowns:
+1. Extract all characters from content (protagonist, supporting, antagonist, narrator)
+2. Create `characters/characters.md` with visual specs for each character
+3. Generate `characters/characters.png` (character reference sheet)

-```markdown
-# [Comic Title] - Knowledge Biography Comic Outline
+**Reference**: `references/character-template.md` for detailed format and examples.

-**Topic**: [topic description]
-**Time Span**: [e.g., 1912-1954]
-**Style**: [selected style]
-**Default Layout**: [selected layout or "varies"]
-**Page Count**: Cover + N pages
-**Generated**: YYYY-MM-DD HH:mm
+### Step 3: Generate Outline

---
+Create `outline.md` with:
+- Metadata (title, style, layout, page count, character reference path)
+- Cover design
+- Each page: layout, panel breakdown, visual prompts

-## Cover
+**Reference**: `references/outline-template.md` for detailed format.

-**Filename**: 00-cover.png
-**Core Message**: [one-liner]
+### Step 4: Generate Images

-**Visual Design**:
- Title typography style
- Main visual composition
- Color scheme
- Subtitle / time span notation
+For each page (cover + pages):

-**Visual Prompt**:
-[Detailed image generation prompt]
+1. Save prompt to `prompts/XX-page.md`
+2. Call image generation skill with:
+   - Base prompt: `references/base-prompt.md`
+   - Character reference (text or image, depending on skill capability)
+   - Page prompt
+   - Output path

---
+**Image Generation Skill Selection**:
+- Check available image generation skills in the environment
+- Adapt parameters based on skill capabilities:
+  - If supports `--promptfiles`: pass prompt files
+  - If supports reference image: pass `characters/characters.png`
+  - If text-only: concatenate prompts into single text
+- If multiple skills available, ask user preference

-## Page 1 / N
+**Session Management**:
+If the image generation skill supports `--sessionId`:
+1. Generate a unique session ID at the start (e.g., `comic-{topic-slug}-{timestamp}`)
+2. Use the same session ID for character sheet and all pages
+3. This ensures visual consistency (character appearance, style) across all generated images

-**Filename**: 01-page.png
-**Layout**: [standard/cinematic/dense/splash/mixed]
-**Narrative Layer**: [Main narrative / Narrator layer / Mixed]

-
-### Step 3: Save Outline
-
-Save as `outline.md` in target directory.
-
-### Step 4: Generate Images Page by Page
-
-For each page:
-
-1. **Save prompt file** to `prompts/` subdirectory
-2. **Call image generation skill**:
-
-```bash
-npx -y bun skills/baoyu-gemini-web/scripts/main.ts \
-  --promptfiles skills/baoyu-comic/prompts/system.md [target]/prompts/00-cover.md \
-  --image [target]/00-cover.png
-```
-
-After each generation:
-1. Confirm success
-2. Report progress: "Generated X/N pages"
-3. Continue to next
+3. Report progress after each generation

 ### Step 5: Completion Report

-## Narrative Structure Principles
+## Style-Specific Guidelines

-### Cover Design
+### Ohmsha Style (`--style ohmsha`)

- Academic gravitas with visual appeal
- Title typography reflecting knowledge/science theme
- Composition hinting at core theme (character silhouette, iconic symbol, concept diagram)
- Subtitle or time span for epic scope
+Additional requirements for educational manga:
+- Default characters: Student (大雄), Mentor (哆啦A梦), Antagonist (胖虎)
+- Custom: `--characters "Student:小明,Mentor:教授"`
+- Must use visual metaphors (gadgets, action scenes) - NO talking heads
+- Page titles: narrative style, not "Page X: Topic"

-### Panel Composition Principles
+**Reference**: `references/ohmsha-guide.md` for detailed guidelines.

-| Panel Type | Recommended Count | Usage |
-|-----------|-------------------|-------|
-| Main narrative | 3-5 per page | Story progression |
-| Concept diagram | 1-2 per page | Visualize abstractions |
-| Narrator panel | 0-1 per page | Commentary, transition, questions |
-| Splash (full/half) | Occasional | Major moments |
+## References

-### Panel Size Reference
-
- **Full page (Splash)**: Major moments, key breakthroughs
- **Half page**: Important scenes, turning points
- **1/3 page**: Standard narrative panels
- **1/4 or smaller**: Quick progression, sequential action
-
-### Concept Visualization Techniques
-
-Transform abstract concepts into concrete visuals:
-
-| Abstract Concept | Visual Approach |
-|-----------------|-----------------|
-| Neural network | Glowing nodes with connecting lines |
-| Gradient descent | Ball rolling down valley terrain |
-| Data flow | Luminous particles flowing through pipes |
-| Algorithm iteration | Ascending spiral staircase |
-| Breakthrough moment | Shattering barrier, piercing light |
-| Logical proof | Building blocks assembling |
-| Uncertainty | Forking paths, fog, multiple shadows |
-
-### Text Element Design
-
-| Text Type | Style | Usage |
-|-----------|-------|-------|
-| Character dialogue | Oval speech bubble | Main narrative speech |
-| Narrator commentary | Rectangular / hand-drawn box | Explanation, commentary |
-| Caption bar | Edge-mounted rectangle | Time, location info |
-| Thought bubble | Cloud shape | Character inner monologue |
-| Term label | Bold / special color | First appearance of technical terms |
-
-## Ohmsha Style Special Requirements
-
-When using `--style ohmsha`, follow these additional guidelines:
-
-### Character Setup (Required)
-
-Define characters before generating outline:
-
-| Role | Default | Traits |
-|------|---------|--------|
-| Student (Role A) | 大雄 | Confused, asks basic but crucial questions, represents reader |
-| Mentor (Role B) | 哆啦A梦 | Knowledgeable, patient, uses gadgets as technical metaphors |
-| Antagonist (Role C, optional) | 胖虎 | Represents misunderstanding, or "noise" in the data |
-
-User can specify custom characters via `--characters "Student:小明,Mentor:教授,Antagonist:Bug怪"`
-
-### Outline Spec Block (Required)
-
-Every ohmsha outline must start with a spec block:
-
-```markdown
-【漫画规格单】
- Language: [Same as input content]
- Style: Ohmsha (Manga Guide), Full Color
- Layout: Vertical Scrolling Comic (竖版条漫)
- Characters: [List character names and roles]
- Page Limit: ≤20 pages
-```
-
-### Visual Metaphor Rules (Critical)
-
-**NEVER** create "talking heads" panels. Every technical concept must become:
-
-1. **A tangible gadget/prop** - Something characters can hold, use, demonstrate
-2. **An action scene** - Characters doing something that illustrates the concept
-3. **A visual environment** - Stepping into a metaphorical space
-
-### Page Title Convention
-
-Avoid AI-style "Title: Subtitle" format. Use narrative descriptions:
- ❌ "Page 3: Introduction to Neural Networks"
- ✓ "Page 3: 大雄被海量单词淹没，哆啦A梦拿出'词向量压缩机'"
-
-### Ending Requirements
-
- NO generic endings ("What will you choose?", "Thanks for reading")
- End with: Technical summary moment OR character achieving a small goal
- Final panel: Sense of accomplishment, not open-ended question
-
-## Notes
-
- Image generation typically takes 30-60 seconds per page
- Auto-retry once on generation failure
- Historical figures rendered in portrait/illustration style for recognizability
- All text in Chinese unless source is in another language
- Each panel description should be detailed enough to serve as standalone AI art prompt
- Maintain style consistency across all pages in series

+
+## Character 2: The Bombe Machine
+
+**Role**: Supporting (anthropomorphized)
+**Appearance**:
+- Large brass and wood cabinet
+- Dial "eyes" that can express states
+- Paper tape "mouth"
+- Indicator lights for emotions
+
+**Expression Range**:
+- Processing: Spinning dials, humming
+- Success: Lights up warmly
+- Stuck: Smoke wisps, stuttering
+
+---
+
+## Reference Sheet Prompt
+
+Character reference sheet in Ligne Claire style, clean lines, flat colors:
+
+TOP ROW - Alan Turing:
+- Front view: Young man, 30s, short dark wavy hair, thoughtful expression, wearing tweed jacket with elbow patches, white shirt
+- 3/4 view: Same character, slight smile, showing profile of nose
+- Expression sheet: Neutral | Excited (eureka moment) | Focused (working) | Worried
+
+BOTTOM ROW - The Bombe Machine (anthropomorphized):
+- Bombe machine as character: Large, brass and wood, dial "eyes", paper tape "mouth"
+- Expressions: Processing (spinning dials) | Success (lights up) | Stuck (smoke wisps)
+
+COLOR PALETTE:

+- Machine: Brass (#B5A642), mahogany (#4E2728), emerald indicators (#2ECC71)
+
+White background, clear labels under each character.
+```
+
+## Handling Age Variants
+
+For biographies spanning many years, define age variants:
+
+```markdown
+## Alan Turing - Age Variants
+
+### Young (1920s, age 10-18)
+- Boyish features, round face
+- School uniform (Sherborne)
+- Curious, eager expression
+
+### Adult (1930s-40s, age 25-35)
+- Angular face, defined jaw
+- Tweed jacket, rumpled appearance
+- Intense, focused expression
+
+### Later (1950s, age 40+)
+- Slightly weathered
+- More casual dress
+- Thoughtful, sometimes melancholic
+```
+
+## Best Practices
+
+| Practice | Description |
+|----------|-------------|
+| Be specific | "Short dark wavy hair, parted left" not just "dark hair" |
+| Use distinguishing features | Glasses, scars, accessories that identify character |
+| Define color codes | Use specific color names or hex codes |
+| Include age markers | Wrinkles, posture, clothing style matching era |
+| Reference real people | For historical figures, note "based on 1940s photographs" |
+
+## Why Character Reference Matters
+
+Without unified character definition, AI generates inconsistent appearances. The reference sheet provides:
+1. Visual anchors for consistent features
+2. Color palettes for consistent coloring
+3. Expression documentation for emotional portrayals

+
+Guidelines for `--style ohmsha` educational manga comics.
+
+## Character Setup
+
+| Role | Default | Traits |
+|------|---------|--------|
+| Student (Role A) | 大雄 | Confused, asks basic but crucial questions, represents reader |
+| Mentor (Role B) | 哆啦A梦 | Knowledgeable, patient, uses gadgets as technical metaphors |
+| Antagonist (Role C, optional) | 胖虎 | Represents misunderstanding, or "noise" in the data |
+
+Custom characters: `--characters "Student:小明,Mentor:教授,Antagonist:Bug怪"`
+
+## Character Reference Sheet Style
+
+For Ohmsha style, use manga/anime style with:
+- Exaggerated expressions for educational clarity
+- Simple, distinctive silhouettes
+- Bright, saturated color palettes
+- Chibi/SD (super-deformed) variants for comedic reactions
+
+## Outline Spec Block
+
+Every ohmsha outline must start with:
+
+```markdown
+【漫画规格单】
+- Language: [Same as input content]
+- Style: Ohmsha (Manga Guide), Full Color
+- Layout: Vertical Scrolling Comic (竖版条漫)
+- Characters: [List character names and roles]
+- Character Reference: characters/characters.png
+- Page Limit: ≤20 pages
+```
+
+## Visual Metaphor Rules (Critical)
+
+**NEVER** create "talking heads" panels. Every technical concept must become:
+
+1. **A tangible gadget/prop** - Something characters can hold, use, demonstrate
+2. **An action scene** - Characters doing something that illustrates the concept
+3. **A visual environment** - Stepping into a metaphorical space
+
+### Examples
+
+| Concept | Bad (Talking Heads) | Good (Visual Metaphor) |
+|---------|---------------------|------------------------|
+| Word embeddings | Characters discussing vectors | 哆啦A梦拿出"词向量压缩机"，把书本压缩成彩色小球 |
+| Gradient descent | Explaining math formula | 大雄在山谷地形上滚球，寻找最低点 |
+| Neural network | Diagram on whiteboard | 角色走进由发光节点组成的网络迷宫 |
+
+## Page Title Convention
+
+Avoid AI-style "Title: Subtitle" format. Use narrative descriptions:
+
+- ❌ "Page 3: Introduction to Neural Networks"
+- ✓ "Page 3: 大雄被海量单词淹没，哆啦A梦拿出'词向量压缩机'"
+
+## Ending Requirements
+
+- NO generic endings ("What will you choose?", "Thanks for reading")
+- End with: Technical summary moment OR character achieving a small goal
+- Final panel: Sense of accomplishment, not open-ended question
+
+### Good Endings
+
+- Student successfully applies learned concept
+- Visual callback to opening problem, now solved
+- Mentor gives summary while student demonstrates understanding
+
+### Bad Endings
+
+- "What do you think?" open questions
+- "Thanks for reading this tutorial"
+- Cliffhanger without resolution
+
+## Layout Preference
+
+Ohmsha style typically uses:
+- `webtoon` (vertical scrolling) - Primary choice
+- `dense` - For information-heavy sections
+- `mixed` - For varied pacing
+
+Avoid `cinematic` and `splash` for educational content.

+**Panel Count**: X
+**Layout Type**: [grid/irregular/splash]
+
+#### Panel 1 (Size: 1/3 page, Position: Top)
+
+**Scene**: [Time, location]
+**Image Description**:
+- Camera angle: [bird's eye / low angle / eye level / close-up / wide shot]
+- Characters: [pose, expression, action]
+- Environment: [scene details, period markers]
+- Lighting: [atmosphere description]
+- Color tone: [palette reference]
+
+**Text Elements**:
+- Dialogue bubble (oval): "Character line"
+- Narrator box (rectangular): 「Narrator commentary」
+- Caption bar: [Background info text]
+
+#### Panel 2...

+**Page Hook**: [Cliffhanger or transition at page end]
+
+**Visual Prompt**:
+[Full page image generation prompt]
+
+---
+
+## Page 2 / N
+...
+```
+
+## Cover Design Principles
+
+- Academic gravitas with visual appeal
+- Title typography reflecting knowledge/science theme
+- Composition hinting at core theme (character silhouette, iconic symbol, concept diagram)
+- Subtitle or time span for epic scope
+
+## Panel Composition Guidelines
+
+| Panel Type | Recommended Count | Usage |
+|-----------|-------------------|-------|
+| Main narrative | 3-5 per page | Story progression |
+| Concept diagram | 1-2 per page | Visualize abstractions |
+| Narrator panel | 0-1 per page | Commentary, transition |
+| Splash (full/half) | Occasional | Major moments |
+
+## Panel Size Reference
+
+- **Full page (Splash)**: Major moments, key breakthroughs
+- **Half page**: Important scenes, turning points
+- **1/3 page**: Standard narrative panels
+- **1/4 or smaller**: Quick progression, sequential action
+
+## Concept Visualization Techniques
+
+Transform abstract concepts into concrete visuals:
+
+| Abstract Concept | Visual Approach |
+|-----------------|-----------------|
+| Neural network | Glowing nodes with connecting lines |
+| Gradient descent | Ball rolling down valley terrain |
+| Data flow | Luminous particles flowing through pipes |
+| Algorithm iteration | Ascending spiral staircase |
+| Breakthrough moment | Shattering barrier, piercing light |
+| Logical proof | Building blocks assembling |
+| Uncertainty | Forking paths, fog, multiple shadows |
+
+## Text Element Design
+
+| Text Type | Style | Usage |
+|-----------|-------|-------|
+| Character dialogue | Oval speech bubble | Main narrative speech |
+| Narrator commentary | Rectangular box | Explanation, commentary |
+| Caption bar | Edge-mounted rectangle | Time, location info |
+| Thought bubble | Cloud shape | Character inner monologue |
+| Term label | Bold / special color | First appearance of technical terms |
+
+## Prompt Structure for Consistency
+
+Each page prompt should include character reference:
+
+```
+[CHARACTER REFERENCE]
+(Key details from characters.md for characters in this page)
+
+[PAGE CONTENT]
+(Specific scene, panel layout, and visual elements)
+
+[CONSISTENCY REMINDER]
+Maintain exact character appearances as defined in character reference.
+- [Character A]: [key identifying features]
+- [Character B]: [key identifying features]

+- Text generation
+- Image generation (download + save)
+- Reference image upload (attach images for vision tasks)
+- Multi-turn conversations within the same executor instance (`keepSession`)
+- Experimental video generation (`generateVideo`) — Gemini may return an async placeholder; download might require Gemini web UI

 ```

+## Executor options (programmatic)
+
+This skill is typically consumed via `createGeminiWebExecutor(geminiOptions)` (see `scripts/executor.ts`).
+
+Key options in `GeminiWebOptions`:
+- `referenceImages?: string | string[]` Upload local images as references (vision input).
+- `keepSession?: boolean` Reuse Gemini `chatMetadata` to continue the same conversation across calls (required if you want reference images to persist across multiple messages).
+- `generateVideo?: string` Generate a video and (best-effort) download to the given path. Gemini may return `video_gen_chip` (async); in that case you must open Gemini web UI to download the result.
+
+Notes:
+- `generateVideo` cannot be combined with `generateImage` / `editImage`.
+- When `keepSession=true` and `referenceImages` is set, reference images are uploaded once per executor instance.

 ### Step 5: Generate Images

+**Session Management**:
+If the image generation skill supports `--sessionId`:
+1. Generate a unique session ID at the start (e.g., `slides-{topic-slug}-{timestamp}`)
+2. Use the same session ID for all slides
+3. This ensures visual consistency (color scheme, style, typography) across all slides
+
 For each slide, generate using:

 ```bash
-/baoyu-gemini-web --promptfiles [SKILL_ROOT]/skills/baoyu-slide-deck/prompts/system.md [TARGET_DIR]/prompts/01-cover.md --image [TARGET_DIR]/01-cover.png
+# With session support

 ```
