-### 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 **If README is outdated**: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 commit -m "chore: release v{VERSION}"
-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`

Use when user asks to "generate image with API", "use official API for images", "create image with OpenAI/Google", or needs API-based generation instead of browser-based.

 - 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.

 ## Error Handling
 
 - Missing API key → error with setup instructions
