/baoyu-cover-image article.md --type conceptual --palette warm --rendering flat-vector

# Style presets (shorthand for palette + rendering)
/baoyu-cover-image article.md --style blueprint
With reference images

/baoyu-cover-image article.md --ref style-ref.png

## File Structure

Output directory per `default_output_dir` preference:
- `same-dir`: `{article-dir}/`
- `imgs-subdir`: `{article-dir}/imgs/`
- `independent` (default): `cover-image/{topic-slug}/`

/ ├── source-{slug}.{ext} # Source files ├── refs/ # Reference images (if provided) │ ├── ref-01-{slug}.{ext} │ └── ref-01-{slug}.md # Description file ├── prompts/cover.md # Generation prompt └── cover.png # Output image


**Slug**: 2-4 words, kebab-case. Conflict: append `-YYYYMMDD-HHMMSS`

## Workflow

### Progress Checklist

Cover Image Progress:

  • Step 0: Check preferences (EXTEND.md) ⛔ BLOCKING
  • Step 1: Analyze content + save refs + determine output dir
  • Step 2: Confirm options (6 dimensions) ⚠️ unless --quick
  • Step 3: Create prompt
  • Step 4: Generate image
  • Step 5: Completion report

### Flow

Input → [Step 0: Preferences] ─┬─ Found → Continue └─ Not found → First-Time Setup ⛔ BLOCKING → Save EXTEND.md → Continue ↓ Analyze + Save Refs → [Output Dir] → [Confirm: 6 Dimensions] → Prompt → Generate → Complete ↓ (skip if --quick or all specified)


### Step 0: Load Preferences ⛔ BLOCKING

Check EXTEND.md existence (priority: project → user):
```bash
test -f .baoyu-skills/baoyu-cover-image/EXTEND.md && echo "project"
test -f "$HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md" && echo "user"
Result Action
Found Load, display summary → Continue
Not found ⛔ Run first-time setup (references/config/first-time-setup.md) → Save → Continue

CRITICAL: If not found, complete setup BEFORE any other steps or questions.

Step 1: Analyze Content

  1. Save reference images (if provided) → references/workflow/reference-images.md
  2. Save source content (if pasted, save to source.md)
  3. Analyze content: topic, tone, keywords, visual metaphors
  4. Deep analyze references ⚠️: Extract specific, concrete elements (see reference-images.md)
  5. Detect language: Compare source, user input, EXTEND.md preference
  6. Determine output directory: Per File Structure rules

Step 2: Confirm Options ⚠️

Full confirmation flow: references/workflow/confirm-options.md

Condition Skipped Still Asked
--quick or quick_mode: true 6 dimensions Aspect ratio (unless --aspect)
All 6 + --aspect specified All None

Step 3: Create Prompt

Save to prompts/cover.md. Template: references/workflow/prompt-template.md

CRITICAL - References in Frontmatter:

  • Files saved to refs/ → Add to frontmatter references list
  • Style extracted verbally (no file) → Omit references, describe in body
  • Before writing → Verify: test -f refs/ref-NN-{slug}.{ext}

Reference elements in body MUST be detailed, prefixed with "MUST"/"REQUIRED", with integration approach.

Step 4: Generate Image

  1. Backup existing cover.png if regenerating
  2. Check image generation skills; if multiple, ask preference
  3. Process references from prompt frontmatter:
    • direct usage → pass via --ref (use ref-capable backend)
    • style/palette → extract traits, append to prompt
  4. Generate: Call skill with prompt file, output path, aspect ratio
  5. On failure: auto-retry once

Step 5: Completion Report

Cover Generated!

Topic: [topic]
Type: [type] | Palette: [palette] | Rendering: [rendering]
Text: [text] | Mood: [mood] | Font: [font] | Aspect: [ratio]
Title: [title or "visual only"]
Language: [lang] | Watermark: [enabled/disabled]
References: [N images or "extracted style" or "none"]
Location: [directory path]

Files:
✓ source-{slug}.{ext}
✓ prompts/cover.md
✓ cover.png

Image Modification

Action Steps
Regenerate Backup → Update prompt file FIRST → Regenerate
Change dimension Backup → Confirm new value → Update prompt → Regenerate

Composition Principles

  • Whitespace: 40-60% breathing room
  • Visual anchor: Main element centered or offset left
  • Characters: Simplified silhouettes; NO realistic humans
  • Title: Use exact title from user/source; never invent

Extension Support

Custom configurations via EXTEND.md. See Step 0 for paths.
