o a tool-managed location, so after generation copy/move the file to the skill's expected output path (e.g., outputs/.../NN-xxx.png). Reference images go in reference_image_paths.

• **Other runtime-native tools** — if the runtime exposes a different native image tool (e.g., Hermes image_generate), use it the same way.
• Otherwise, if exactly one non-native backend is installed (e.g., baoyu-image-gen), use it.
• Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.

4. **If none are available**, tell the user and ask how to proceed.

**⛔ Never substitute SVG, HTML, canvas, or other code-based rendering for raster image generation.** Codex imagegen's own description says it should be used "when the output should be a bitmap asset rather than repo-native code or vector." If you cannot resolve a raster backend via step 3, fall through to step 4 and ask the user — do **not** silently emit SVG, write inline <svg> markup, or produce HTML/CSS art as a substitute. This applies even if the article/section seems "diagram-like": the consumer skill calling this rule has already decided that a raster image is what it needs.

**⛔ Never repair rendered text by painting over a generated bitmap.** Do not use ImageMagick, Pillow, Canvas, SVG, HTML/CSS, OCR scripts, or any other programmatic overlay to cover, rewrite, erase, stroke, or replace labels, headings, callouts, data values, or any other text inside an already generated infographic. If text is wrong or unclear, regenerate from a corrected prompt, switch to a layout with less on-image text, or ask the user which imperfect candidate to keep.

Setting preferred_image_backend: ask forces the step-3 prompt every run regardless of available backends. Users change the pinned backend via the ## Changing Preferences section below.

**Prompt file requirement (hard)**: write each image's full, final prompt to a standalone file under prompts/ (naming: NN-{type}-[slug].md) BEFORE invoking any backend. The backend receives the prompt file (or its content); the file is the reproducibility record and lets you switch backends without regenerating prompts.

Concrete tool names (imagegen, GenerateImage, image_generate, baoyu-image-gen) above are examples — substitute the local equivalents under the same rule.

Reference Images

Users may supply reference images to guide style, palette, composition, or subject.

**Intake**: Accept via --ref <files...> or when the user provides file paths / pastes images in conversation.

• File path(s) → copy to refs/NN-ref-{slug}.{ext} alongside the output
• Pasted image with no path → ask the user for the path (per the User Input Tools rule above), or extract style traits verbally as a text fallback
• No reference → skip this section

**Usage modes** (per reference):

| Usage | Effect |

|-------|--------|

| direct | Pass the file to the backend as a reference image |

| style | Extract style traits (line treatment, texture, mood) and append to the prompt body |

| palette | Extract hex colors from the image and append to the prompt body |

**Record in prompts/infographic.md frontmatter** when refs exist:

references:
  - ref_id: 01
    filename: 01-ref-brand.png
    usage: direct

**At generation time**:

• Verify each referenced file exists on disk
• If usage: direct AND the chosen backend accepts reference images (e.g., baoyu-image-gen via --ref) → pass the file via the backend's ref parameter
• Otherwise → embed extracted style/palette traits in the prompt text

Confirmation Policy

Default behavior: **confirm before generation**.

• Treat explicit skill invocation, a file path, a matched keyword shortcut, EXTEND.md defaults, and the documented default combination as **recommendation inputs only**. None of them authorizes skipping confirmation.
• Do **not** start Step 5 or Step 6 until the user confirms the combination/aspect/language/backend choices.
• Skip confirmation only when the current request explicitly says to do so, for example: --no-confirm, "直接生成", "不用确认", "跳过确认", "按默认出图", or equivalent wording.
• If confirmation is skipped explicitly, state the assumed combination/aspect/language/backend in the next user-facing update before generating.
