--- name: baoyu-cover-image description: Generates article cover images with 5 dimensions (type, palette, rendering, text, mood) combining 10 color palettes and 7 rendering styles. Supports cinematic (2.35:1), widescreen (16:9), and square (1:1) aspects. Use when user asks to "generate cover image", "create article cover", or "make cover". version: 1.56.1 metadata: openclaw: homepage: https://github.com/JimLiu/baoyu-skills#baoyu-cover-image --- # Cover Image Generator Generate elegant cover images for articles with 5-dimensional customization. ## Usage ```bash # Auto-select dimensions based on content /baoyu-cover-image path/to/article.md # Quick mode: skip confirmation /baoyu-cover-image article.md --quick # Specify dimensions /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 # Direct content input /baoyu-cover-image --palette mono --aspect 1:1 --quick [paste content] ``` ## Options | Option | Description | |--------|-------------| | `--type <name>` | hero, conceptual, typography, metaphor, scene, minimal | | `--palette <name>` | warm, elegant, cool, dark, earth, vivid, pastel, mono, retro, duotone | | `--rendering <name>` | flat-vector, hand-drawn, painterly, digital, pixel, chalk, screen-print | | `--style <name>` | Preset shorthand (see [Style Presets](references/style-presets.md)) | | `--text <level>` | none, title-only, title-subtitle, text-rich | | `--mood <level>` | subtle, balanced, bold | | `--font <name>` | clean, handwritten, serif, display | | `--aspect <ratio>` | 16:9 (default), 2.35:1, 4:3, 3:2, 1:1, 3:4 | | `--lang <code>` | Title language (en, zh, ja, etc.) | | `--no-title` | Alias for `--text none` | | `--quick` | Skip confirmation, use auto-selection | | `--ref <files...>` | Reference images for style/composition guidance | ## Five Dimensions | Dimension | Values | Default | |-----------|--------|---------| | **Type** | hero, conceptual, typography, metaphor, scene, minimal | auto | | **Palette** | warm, elegant, cool, dark, earth, vivid, pastel, mono, retro, duotone | auto | | **Rendering** | flat-vector, hand-drawn, painterly, digital, pixel, chalk, screen-print | auto | | **Text** | none, title-only, title-subtitle, text-rich | title-only | | **Mood** | subtle, balanced, bold | balanced | | **Font** | clean, handwritten, serif, display | clean | Auto-selection rules: [references/auto-selection.md](references/auto-selection.md) ## Galleries **Types**: hero, conceptual, typography, metaphor, scene, minimal → Details: [references/types.md](references/types.md) **Palettes**: warm, elegant, cool, dark, earth, vivid, pastel, mono, retro, duotone → Details: [references/palettes/](references/palettes/) **Renderings**: flat-vector, hand-drawn, painterly, digital, pixel, chalk, screen-print → Details: [references/renderings/](references/renderings/) **Text Levels**: none (pure visual) | title-only (default) | title-subtitle | text-rich (with tags) → Details: [references/dimensions/text.md](references/dimensions/text.md) **Mood Levels**: subtle (low contrast) | balanced (default) | bold (high contrast) → Details: [references/dimensions/mood.md](references/dimensions/mood.md) **Fonts**: clean (sans-serif) | handwritten | serif | display (bold decorative) → Details: [references/dimensions/font.md](references/dimensions/font.md) ## File Structure Output directory per `default_output_dir` preference: - `same-dir`: `{article-dir}/` - `imgs-subdir`: `{article-dir}/imgs/` - `independent` (default): `cover-image/{topic-slug}/` ``` <output-dir>/ ├── 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 # macOS, Linux, WSL, Git Bash test -f .baoyu-skills/baoyu-cover-image/EXTEND.md && echo "project" test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-cover-image/EXTEND.md" && echo "xdg" test -f "$HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md" && echo "user" ``` ```powershell # PowerShell (Windows) if (Test-Path .baoyu-skills/baoyu-cover-image/EXTEND.md) { "project" } $xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" } if (Test-Path "$xdg/baoyu-skills/baoyu-cover-image/EXTEND.md") { "xdg" } if (Test-Path "$HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md") { "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 **⚠️ People in Reference Images — MUST follow all 3 rules:** If reference images contain **people** who should appear in the cover: 1. **`usage: direct`** — MUST set in refs description file. NEVER use `style` or `palette` when people need to appear 2. **Per-character description** — MUST describe each person's distinctive features (hair, glasses, skin tone, clothing) in `refs/ref-NN-{slug}.md`. Vague descriptions like "a man" will fail 3. **`--ref` flag** — MUST pass reference image via `--ref` in Step 4 so the model sees actual faces See [reference-images.md § Character Analysis](references/workflow/reference-images.md) for description format. ### Step 2: Confirm Options ⚠️ **MUST use `AskUserQuestion` tool** to present options as interactive selection — NOT plain text tables. Present up to 4 questions in a single `AskUserQuestion` call (Type, Palette, Rendering, Font + Settings). Each question shows the recommended option first with reason, followed by alternatives. Full confirmation flow and question format: [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 ``` Cover Generated!
