Conflict: append YYYYMMDD HHMMSS Workflow Progress Checklist Flow Step 0: Load Preferences ⛔ BLOCKING Check EXTEND.md existence (priority: project → user): Result Action Found Load, display summary → Continue Not found ⛔ Run first time setup ([references/config/first time setup.md](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](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](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](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 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.
