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):

test -f .baoyu-skills/baoyu-cover-image/EXTEND.md && echo "project"
test -f "$HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md" && echo "user"

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

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

Image Modification

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.
