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 ``` Cover Generated!
