chore: release v1.23.0

refactor(baoyu-cover-image): replace 20 styles with 5D palette×rendering system
Migrate from 4-dimension (Type×Style×Text×Mood) to 5-dimension (Type×Palette×Rendering×Text×Mood) system. 9 palettes × 6 renderings = 54 combinations replacing 20 fixed styles. Add style presets for backward compatibility, v2→v3 schema migration, and new reference structure (palettes/, renderings/, workflow/).

-### Step 5: Check README Updates
+### Step 5: Group Changes by Skill/Module

-**IMPORTANT**: Before updating version file, check if README needs updates.
+Analyze commits since last tag and group by affected skill/module:

-1. **Scan for README files**: `README*.md` in project root
-2. **For each skill/feature changed**, check if README documentation matches:
-   - Options/flags documented correctly
-   - Usage examples reflect current syntax
-   - Feature descriptions are accurate
-3. **If README is outdated**:
-   - Update README.md (and README.zh.md if exists) to reflect changes
-   - Include in release commit
+1. **Identify changed files** per commit
+2. **Group by skill/module**:
+   - `skills/<skill-name>/*` → Group under that skill
+   - Root files (CLAUDE.md, etc.) → Group as "project"
+   - Multiple skills in one commit → Split into multiple groups
+3. **For each group**, identify related README updates needed
+
+**Example Grouping**:
+```
+baoyu-cover-image:
+  - feat: add new style options
+  - fix: handle transparent backgrounds
+  → README updates: options table
+
+baoyu-comic:
+  - refactor: improve panel layout algorithm
+  → No README updates needed
+
+project:
+  - docs: update CLAUDE.md architecture section
+```
+
+### Step 6: Commit Each Skill/Module Separately
+
+For each skill/module group (in order of changes):
+
+1. **Check README updates needed**:
+   - Scan `README*.md` for mentions of this skill/module
+   - Verify options/flags documented correctly
+   - Update usage examples if syntax changed
+   - Update feature descriptions if behavior changed
+
+2. **Stage and commit**:
+   ```bash
+   git add skills/<skill-name>/*
+   git add README.md README.zh.md  # If updated for this skill
+   git commit -m "<type>(<skill-name>): <meaningful description>"
+   ```
+
+3. **Commit message format**:
+   - Use conventional commit format: `<type>(<scope>): <description>`
+   - `<type>`: feat, fix, refactor, docs, perf, etc.
+   - `<scope>`: skill name or "project"
+   - `<description>`: Clear, meaningful description of changes
+
+**Example Commits**:
+```bash
+git commit -m "feat(baoyu-cover-image): add watercolor and minimalist styles"
+git commit -m "fix(baoyu-comic): improve panel layout for long dialogues"
+git commit -m "docs(project): update architecture documentation"

-git tag v{VERSION}
+Before creating the release commit, ask user to confirm:
+
+**Use AskUserQuestion with two questions**:
+
+1. **Version bump** (single select):
+   - Show recommended version based on Step 3 analysis
+   - Options: recommended (with label), other semver options
+   - Example: `1.2.3 → 1.3.0 (Recommended)`, `1.2.3 → 1.2.4`, `1.2.3 → 2.0.0`

+**1.1 Determine Input Type**
+
+| Input | Output Directory | Next |
+|-------|------------------|------|
+| File path | Ask user (1.2) | → 1.2 |
+| Pasted content | `illustrations/{topic-slug}/` | → 1.4 |
+
+**1.2 Determine Output Directory** (file path input only)
+
+Check `default_output_dir` in preferences:
+
+| Preference Value | Action |
+|------------------|--------|
+| `same-dir` | Use `{article-dir}/`, display "Output: {path}" |
+| `imgs-subdir` | Use `{article-dir}/imgs/`, display "Output: {path}" |
+| `illustrations-subdir` | Use `{article-dir}/illustrations/`, display "Output: {path}" |
+| `independent` | Use `illustrations/{topic-slug}/`, display "Output: {path}" |
+| Not configured | **MUST** ask with AskUserQuestion ↓ |
+
+**AskUserQuestion** (when no preference):
+- `{article-dir}/` - Same directory as article
+- `{article-dir}/imgs/` - Images subdirectory
+- `{article-dir}/illustrations/` - Illustrations subdirectory (Recommended)
+- `illustrations/{topic-slug}/` - Independent directory
+- Save as default - Remember this choice for future runs
+
+**1.3 Check Existing Images**
+
+Scan target directory for `.png/.jpg/.webp` files.
+
+If images exist → AskUserQuestion: How to handle?
+- `supplement` - Keep existing, generate only new positions
+- `overwrite` - Overwrite same-name files
+- `regenerate` - Clear all and regenerate
+
+**1.4 Confirm Article Update Method** (file path input only)
+
+AskUserQuestion: How to update article?
+- `update` - Modify original file directly
+- `copy` - Create `{name}-illustrated.md` copy
+
+**1.5 Load Preferences (EXTEND.md)**

 ## File Structure

-Each session creates an independent directory named by content slug:
+Output directory depends on `default_output_dir` preference:
+
+| Preference | Output Path |
+|------------|-------------|
+| `same-dir` | `{article-dir}/` |
+| `imgs-subdir` | `{article-dir}/imgs/` |
+| `independent` (default) | `cover-image/{topic-slug}/` |
+| Pasted content | `cover-image/{topic-slug}/` (always) |

 ├── prompts/cover.md       # Generation prompt
 └── cover.png              # Output image
 ```

-**Slug Generation**:
-1. Extract main topic from content (2-4 words, kebab-case)
-2. Example: "The Future of AI" → `future-of-ai`
-
-**Conflict Resolution**:
-If `cover-image/{topic-slug}/` already exists:
- Append timestamp: `{topic-slug}-YYYYMMDD-HHMMSS`
- Example: `ai-future` exists → `ai-future-20260118-143052`
-
-**Source Files**:
-Copy all sources with naming `source-{slug}.{ext}`:
- `source-article.md`, `source-reference.png`, etc.
- Multiple sources supported: text, images, files from conversation
+**Slug**: Extract main topic (2-4 words, kebab-case). Example: "The Future of AI" → `future-of-ai`

-   - Detect source content language
-   - Note user's input language (from conversation)
-   - Compare with language preference in EXTEND.md
+1. **Save source content** (if pasted, save to `source.md` in target directory; if file path, use as-is)
+2. **Content analysis**: Extract topic, core message, tone, keywords; identify visual metaphors; detect content type
+3. **Language detection**: Detect source language, note user's input language, compare with EXTEND.md preference
+4. **Determine output directory** per File Structure rules. If no `default_output_dir` preference + file path input, include in Step 2 Q4

 ### Step 2: Confirm Options ⚠️

-**Purpose**: Validate all 4 dimensions. **Skip if `--quick` flag OR all 4 dimensions specified via CLI.**
+Validate all 5 dimensions + aspect ratio. Full confirmation flow: [references/workflow/confirm-options.md](references/workflow/confirm-options.md)

 **Skip Conditions**:
-| Condition | Behavior |
-|-----------|----------|
-| `--quick` flag | Auto-select missing dimensions, skip to Step 3 |
-| All 4 dimensions specified | Use specified values, skip to Step 3 |
-| `quick_mode: true` in EXTEND.md | Auto-select missing dimensions, skip to Step 3 |
-| Otherwise | Show confirmation (current behavior) |

-**Quick Mode Output** (when skipping confirmation):
-
-```
-Quick Mode: Auto-selected dimensions
-• Type: [type] ([reason])
-• Style: [style] ([reason])
-• Text: [text] ([reason])

+| All 5 + `--aspect` specified | All | None |

 ### Step 3: Create Prompt

-Save to `prompts/cover.md`:
-
-```markdown
-# Content Context
-Article title: [full original title from source]
-Content summary: [2-3 sentence summary of key points and themes]
-Keywords: [5-8 key terms extracted from content]
-
-# Visual Design
-Cover theme: [2-3 words visual interpretation]
-Type: [confirmed type]
-Style: [confirmed style]
-Text level: [confirmed text level]
-Mood: [confirmed mood]
-Aspect ratio: [confirmed ratio]
-Language: [confirmed language]
-
-# Text Elements
-[Based on text level:]
- none: "No text elements"
- title-only: "Title: [max 8 chars headline]"
- title-subtitle: "Title: [headline] / Subtitle: [max 15 chars context]"
- text-rich: "Title: [headline] / Subtitle: [context] / Tags: [2-4 keywords]"
-
-# Mood Application
-[Based on mood level:]
- subtle: "Use low contrast, muted colors, light visual weight, calm aesthetic"
- balanced: "Use medium contrast, normal saturation, balanced visual weight"
- bold: "Use high contrast, vivid saturated colors, heavy visual weight, dynamic energy"
-
-# Composition
-Type composition:
- [Type-specific layout and structure]
-
-Visual composition:
- Main visual: [metaphor derived from content meaning]
- Layout: [positioning based on type and aspect ratio]
- Decorative: [style elements that reinforce content theme]
-
-Color scheme: [primary, background, accent from style, adjusted by mood]
-Type notes: [key characteristics from type definition]
-Style notes: [key characteristics from style definition]
-
-[Watermark section if enabled]
-```
-
-**Content-Driven Design**:
- Article title and summary inform the visual metaphor choice
- Keywords guide decorative elements and symbols
- The skill controls visual style; the content drives meaning
-
-**Type-Specific Composition**:
-
-| Type | Composition Guidelines |
-|------|------------------------|
-| `hero` | Large focal visual (60-70% area), title overlay on visual, dramatic composition |
-| `conceptual` | Abstract shapes representing core concepts, information hierarchy, clean zones |
-| `typography` | Title as primary element (40%+ area), minimal supporting visuals, strong hierarchy |
-| `metaphor` | Concrete object/scene representing abstract idea, symbolic elements, emotional resonance |
-| `scene` | Atmospheric environment, narrative elements, mood-setting lighting and colors |
-| `minimal` | Single focal element, generous whitespace (60%+), essential shapes only |
-
-**Title guidelines** (when text level includes title):
- Max 8 characters, punchy headline
- Use hooks: numbers, questions, contrasts
- Match confirmed language
-
-**Watermark Application** (if enabled in preferences):
-Add to prompt:
-```
-Include a subtle watermark "[content]" positioned at [position]
-with approximately [opacity*100]% visibility. The watermark should
-be legible but not distracting from the main content.
-```
-Reference: `references/config/watermark-guide.md`
+Save to `prompts/cover.md`. Full template: [references/workflow/prompt-template.md](references/workflow/prompt-template.md)

 ### Step 4: Generate Image

-**Backup Existing Cover** (if regenerating):
-If `cover.png` already exists in the output directory:
- Rename to `cover-backup-YYYYMMDD-HHMMSS.png`
-
-**Image Generation Skill Selection**:
-1. Check available image generation skills
-2. If multiple skills available, ask user preference
-3. Call selected skill with:
-   - Prompt file path
-   - Output image path: `cover.png`
-   - Aspect ratio parameter

+[Based on mood level:]
+- subtle: "Use low contrast, muted colors, light visual weight, calm aesthetic"
+- balanced: "Use medium contrast, normal saturation, balanced visual weight"
+- bold: "Use high contrast, vivid saturated colors, heavy visual weight, dynamic energy"
+
+# Composition
+Type composition:
+- [Type-specific layout and structure]
+
+Visual composition:
+- Main visual: [metaphor derived from content meaning]
+- Layout: [positioning based on type and aspect ratio]
+- Decorative: [palette-specific elements that reinforce content theme]
+
+Color scheme: [primary, background, accent from palette definition, adjusted by mood]
+Rendering notes: [key characteristics from rendering definition — lines, texture, depth, element style]
+Type notes: [key characteristics from type definition]
+Palette notes: [key characteristics from palette definition]
+
+[Watermark section if enabled]
+```
+
+## Content-Driven Design
+
+- Article title and summary inform the visual metaphor choice
+- Keywords guide decorative elements and symbols
+- The skill controls visual style; the content drives meaning
+
+## Type-Specific Composition
+
+| Type | Composition Guidelines |
+|------|------------------------|
+| `hero` | Large focal visual (60-70% area), title overlay on visual, dramatic composition |
+| `conceptual` | Abstract shapes representing core concepts, information hierarchy, clean zones |
+| `typography` | Title as primary element (40%+ area), minimal supporting visuals, strong hierarchy |
+| `metaphor` | Concrete object/scene representing abstract idea, symbolic elements, emotional resonance |
+| `scene` | Atmospheric environment, narrative elements, mood-setting lighting and colors |
+| `minimal` | Single focal element, generous whitespace (60%+), essential shapes only |
+
+## Title Guidelines
+
+When text level includes title:
+- Max 8 characters, punchy headline
+- Use engagement hooks: numbers ("3个陷阱"), questions ("Why X?"), contrasts ("A vs B"), pain points ("别再X了")
+- Match confirmed language
+
+## Watermark Application
+
+If enabled in preferences, add to prompt:
+
+```
+Include a subtle watermark "[content]" positioned at [position].
+The watermark should be legible but not distracting from the main content.
+```

 - Google Imagen: uses `aspectRatio` parameter
 - OpenAI: maps to closest supported size

+## Parallel Generation
+
+Supports concurrent image generation via background subagents for batch operations.
+
+| Setting | Value |
+|---------|-------|
+| Recommended concurrency | 4 subagents |
+| Max concurrency | 8 subagents |
+| Use case | Batch generation (slides, comics, infographics) |
+
+**Agent Implementation**:
+```
+# Launch multiple generations in parallel using Task tool
+# Each Task runs as background subagent with run_in_background=true
+# Collect results via TaskOutput when all complete
+```
+
+**Best Practice**: When generating 4+ images, spawn background subagents (recommended 4 concurrent) instead of sequential execution.

JadeLiang	5a11b49b00	Fix: Windows compatibility for baoyu-post-to-wechat ## Problem The baoyu-post-to-wechat skill failed on Windows due to: 1. `new URL(import.meta.url).pathname` returns incorrect path format on Windows 2. Copy/paste operations used `xdotool` (Linux tool) which doesn't exist on Windows ## Solution 1. md-to-wechat.ts: Use `fileURLToPath()` to correctly resolve file paths on Windows 2. wechat-article.ts: Use CDP `Input.dispatchKeyEvent` for copy/paste operations - Replaces system-dependent tools (xdotool/osascript) - Works consistently across Windows/macOS/Linux - More reliable as it operates within Chrome session ## Changes - Import `fileURLToPath` from 'node:url' - Replace `new URL(import.meta.url).pathname` with `fileURLToPath(import.meta.url)` - Replace system tool calls with CDP keyboard events for Ctrl+C and Ctrl+V - Add platform-specific modifier handling (Cmd for macOS, Ctrl for Windows/Linux) ## Testing - Tested successfully on Windows 11 - Markdown conversion works correctly - HTML copy/paste to WeChat editor works correctly Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2026-01-25 15:24:04 +08:00
