name: surgepix-generate-illustrations description: Generate 16:9 horizontal article illustrations (1536×864, hand-drawn style) via SurgePix for blogs, WeChat Official Account articles, and tweets. Use when the user wants 文章配图, 公众号配图, 博客插图, 推文配图, or horizontal editorial illustrations. Output rule: API returns only ONE download URL — single image = image URL; multiple images = ZIP URL (resultType zip). When ZIP, show ONLY that download link; NEVER fabricate per-image URLs (img1.png, 第1张, etc.). Do NOT use for 小红书/RED/竖版套图 — use surgepix-generate-xhs.

SurgePix Generate Illustrations

Generate 16:9 horizontal article illustrations (hand-drawn style, fixed 1536×864) from a topic or per-shot specifications, and get a download URL.

Skill router (read first)

Use this skill	Use surgepix-generate-xhs instead
公众号 / 博客 / 推文 / 文章	小红书 / RED / 笔记 / 套图
16:9 horizontal editorial illustrations	Vertical carousel (cover + content pages)
Hand-drawn style with handwritten annotations	Social post image set (modern/vintage/bold presets)

Do NOT use this skill when:

• User wants 小红书套图, 小红书笔记图, 竖版轮播, or RED post images
• User explicitly mentions 小红书, RED, 笔记, or vertical social carousel

Ambiguous input: If the user only says「配图」「做几张图」without platform or aspect ratio, ask:

是要 小红书竖版套图（笔记轮播），还是 公众号/博客横版插图（16:9）？

When to use

• User says "文章配图", "博客插图", "公众号配图", "推文配图", "generate illustrations", "make article images"
• User wants horizontal (16:9) illustrations for blog posts, WeChat Official Account articles, tweets, or other editorial content
• User provides a topic/article summary or detailed per-shot specifications
• User says「生成配图」and context indicates 公众号/博客/文章/横版 (not 小红书/笔记/竖版)

Prerequisites

• Node.js >= 18
• SURGEPIX_API_KEY configured (see Step 0)

What the Skill Does

Action	Description
Generate illustrations	Create 16:9 horizontal illustrations from topic or per-shot specs
Upload reference image	Upload a style reference image to calibrate the illustration style
Check task status	Poll a generation task by taskId to check progress
Download result	Retrieve the download URL (single image URL or ZIP for multiple)

The script always submits the task asynchronously (the API returns a taskId immediately). The --nowait flag controls what the script does next:

• --nowait false (default) — the script polls internally until the task is succeeded/failed and returns the final download URL in one call.
• --nowait true — the script returns the taskId immediately without waiting; resolve it later with the surgepix-query-task skill.

Setup

Requirement: Set the SURGEPIX_API_KEY environment variable. Get your API Key at your platform's API management page.

export SURGEPIX_API_KEY=your-api-key-here

This skill uses the script at <skills-dir>/surgepix-generate-illustrations/scripts/generate_illustrations.mjs.

Usage Examples

Auto-generate by topic (simplest mode):

node "<skills-dir>/surgepix-generate-illustrations/scripts/generate_illustrations.mjs" \
  --topic "内容生产闭环：从选题、写作到分发与复盘" \
  --count 4
# Output (JSON):
#   {"ok":true,"taskId":"task_abc123","sessionId":123,"progress":"succeeded","download":"https://...illustrations.zip","imageCount":4,"resultType":"zip","note":"API 仅返回 ZIP 下载地址，不含单张图片 URL；禁止编造单张链接"}
#   ← Save sessionId for retries

Per-shot detailed specifications (inline JSON):

node "<skills-dir>/surgepix-generate-illustrations/scripts/generate_illustrations.mjs" \
  --shots '[{"theme":"内容生产闭环","structureType":"Workflow","coreIdea":"用传送带表现选题→写作→分发→复盘","composition":"小黑站在传送带旁推纸条","elements":["传送带","纸条","四个槽口"],"labels":["选题","写作","分发","复盘"]},{"theme":"算法推荐与人工干预","structureType":"before-after","coreIdea":"对比纯算法推流与人工校准后两种状态"}]'
# Generates 2 illustrations with precise control

Per-shot from file (recommended for complex specs):

node "<skills-dir>/surgepix-generate-illustrations/scripts/generate_illustrations.mjs" \
  --shots-file ./illustration-specs.json \
  --reference ./style-ref.png

Iterate with same session ID:

node "<skills-dir>/surgepix-generate-illustrations/scripts/generate_illustrations.mjs" \
  --topic "内容生产闭环：从选题、写作到分发与复盘" \
  --count 4 \
  --session-id 123                ← Pass the sessionId from previous output (number type)
# Both versions appear in the same session on the platform frontend.

Workflow

Step 0: Check environment (required)

Before running, verify config:

node "<skills-dir>/surgepix-setup/scripts/check_env.mjs"

• Exit 0 → proceed to Step 1
• Exit 1 → follow surgepix-setup skill to configure .env, then retry

Step 1: Gather inputs

At least one of --topic or --shots/--shots-file must be provided.

• Topic (conditionally required): article topic or body text summary. Required when --shots is not provided.
• Shots (optional): per-shot illustration specifications as a JSON array (inline via --shots or from file via --shots-file). When provided, takes priority over --topic/--count and generates images in array order.
• Count (optional, default 4, range 1–9): number of images to auto-generate from --topic. Only effective when --shots is not provided.
• Reference image (optional): local file path or image URL for style calibration; script uploads automatically. Repeatable for multiple images. Supported formats: JPEG, JPG, PNG, WEBP — max 20MB each.
• Session ID (optional): if the user is iterating on a previous result, ask them to provide the sessionId (number type) printed by the last run.

Shot Specification Object (for --shots array elements):

Field	Required	Description
theme	Yes	This image's theme
structureType	No	Structure type, e.g. Workflow / before-after / concept metaphor
coreIdea	No	Core message this image should convey
composition	No	Specific scene description
elements	No	Suggested visual elements (string array)
labels	No	Suggested Chinese handwritten annotation labels (string array)

Step 2: Run generate-illustrations

node "<skills-dir>/surgepix-generate-illustrations/scripts/generate_illustrations.mjs" \
  [--topic "<text>"] [--shots '<json>'] [--shots-file "<path>"] \
  [--count <1-9>] [--reference "<path-or-url>" ...] \
  [--session-id <id>] [--nowait <true|false>]

Flag	Description
--topic <text>	Article topic or body summary (required when shots not provided)
--shots <json>	Per-shot specs as inline JSON array
--shots-file <path>	Per-shot specs from a JSON file
--count <1-9>	Auto-generate count from topic, default 4
--reference <path-or-url>	Style reference image (local path auto-uploaded; repeatable)
--session-id <id>	Session ID; pass the sessionId (number type) from a previous run to iterate
--nowait <true|false>	Wait mode, default false (see below)

The request is always submitted asynchronously. --nowait false (default) makes the script poll internally until the task completes and returns the final download; --nowait true makes the script return the taskId immediately, to be resolved later via the surgepix-query-task skill.

Step 3: Parse output

Sync success (--nowait false, stdout):

{"ok":true,"taskId":"task_xxx","sessionId":123,"progress":"succeeded","download":"https://...illustrations.zip","imageCount":4,"resultType":"zip","note":"API 仅返回 ZIP 下载地址，不含单张图片 URL；禁止编造单张链接"}

CRITICAL — 禁止编造单张图片链接

• API 的 taskResult 只有 download 一个字段，没有单张图片 URL 列表。
• resultType: "zip"（或 imageCount > 1）时：只展示 download ZIP 链接，告知用户下载 ZIP 后解压获取各张图。
• 绝对禁止根据 imageCount、主题或 shots 推测并编造 image1.png、image2.png 等单张链接。
• resultType: "image"（imageCount === 1）时：download 才是单张图片 URL，也只展示这一个链接。

Async submitted (--nowait true, stdout) — resolve later with the surgepix-query-task skill:

{"ok":true,"async":true,"taskId":"task_xxx","sessionId":123,"progress":"processing","download":null,"hint":"..."}

Failure (stderr):

{"ok":false,"error":"..."}

Step 4: Present result

CRITICAL — 禁止编造单张图片链接（幻觉高发区）

• 脚本输出 resultType: "zip" 或 imageCount > 1 时，API 只返回一个 ZIP 的 download 链接，没有单张图片 URL。
• 只向用户展示 download 这一个 ZIP 链接，说明「共 N 张图，请下载 ZIP 解压查看」。
• 绝对禁止编造类似「第 1 张：https://.../img1.png」「第 2 张：https://.../img2.png」的链接——这些 URL 不存在。
• 若用户需要单张直链，只能重新以 --count 1 或 --shots 只含 1 条重新生成。

• On success: Show only the download URL from script output. Always show sessionId (note: it is a number type, e.g. 123) so the user can pass it in a retry if needed.
  • resultType: "image" (imageCount === 1): download is a single image URL
  • resultType: "zip" (imageCount > 1): download is a ZIP file — do not list per-image URLs
  • On failure: Report the error field. Common causes:
    • Missing required parameter — neither --topic nor --shots/--shots-file provided
    • --count out of range (must be 1–9)
    • --shots JSON parse error
    • Reference image format not supported or exceeds 20MB
    • Generation failed — internal error; retry or simplify the topic
  • The result is automatically attached to the session (auto-created or reused). The user can open the platform frontend to see all iterations in one place.
  • If the user is not satisfied and wants to iterate, instruct them to pass --session-id <sessionId> (number type) in the next run — both versions appear in the same session history on the frontend.

• Resolution: 1536×864 pixels
• Style: Hand-drawn illustration style with Chinese handwritten annotations

---

Rules

• This skill is for 16:9 horizontal article/editorial illustrations only — never use it for 小红书/RED vertical套图 (use surgepix-generate-xhs)
• If the user only says「配图」without 小红书/公众号/博客/横版/竖版, ask which platform and aspect ratio before running
• ALWAYS run check_env.mjs before first use in a session
• At least one of --topic or --shots/--shots-file must be provided
• --count must be 1–9 when provided; only effective in topic mode (no --shots)
• When --shots is provided, it takes priority over --topic and --count; images are generated in array order
• The request is always submitted asynchronously; --nowait only controls whether the script polls locally (false, default) or returns the taskId immediately (true) — do not treat it as the API noWait field
• In async mode (--nowait true), guide the user/Agent to resolve the taskId via the surgepix-query-task skill
• If the user wants to iterate, they pass --session-id 123 in the next run — both versions appear in the same session on the frontend.
• If --session-id is omitted, the platform auto-creates a new session for the run.
• NEVER pass local reference image paths to the API — script handles upload internally
• NEVER invent download URLs — only use the download value from the output
• NEVER invent per-image URLs when resultType is zip — the API does not return individual image links; only the ZIP download exists. Do not fabricate img1.png, img2.png, or numbered image URLs.
• When resultType: "zip", present only the ZIP download link and tell the user to unzip for individual images
• NEVER echo auth tokens in logs or output
• The download URL is valid for 24 hours; download before it expires.
• Reference image supported formats: JPEG, JPG, PNG, WEBP — max 20MB each.
• When multiple images are generated, the download is a ZIP containing all illustrations in order.
• For complex per-shot specifications, prefer --shots-file over inline --shots to avoid shell escaping issues.
• Each shot's theme field is required; other fields (structureType, coreIdea, composition, elements, labels) are optional but recommended for precise control.
