概述

小题 XT MCP 强制前置闸门

本节优先于正文中任何旧版配置、手动兜底或“选择是否使用 MCP”的说明。加载本 Skill 后，第一步只检查当前 Agent 是否实际配置并可用名为 ai-tool-center 的 MCP；以当前 Agent 的 MCP 服务器列表、已注册工具列表或可用连接状态为准。已检测到且可用时直接继续，不重复询问配置、不索取 API Key；未检测到、无法确认或连接失败时，只发送配置提醒并停止，不得先读取外部链接、调用平台数据、生成/分析媒体或使用其他能力绕过闸门。

用户只说“已配置”、只提供 URL/API Key，或配置后尚未重启验证，均不算可用。用户明确不配置时，只有在其再次明确授权无 MCP 继续后，才可执行不依赖 MCP 的部分，并标记受影响能力，不得伪称 MCP 调用成功。

MCP 配置提醒

未检测到可用 MCP 时，提示用户到 xt.gbotai.cn 申请 API Key，在当前 Agent 的 MCP 设置中新增以下配置，完全退出并重启 Agent，确认工具列表出现 ai-tool-center 后再回复“已配置 MCP”；真实 Key 不得写入 Skill、日志或交付物。

  "mcpServers": {
    "ai-tool-center": {
      "url": "https://middle-aitool.gbotai.cn/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_API_KEY>"
      }
    }
  }
}

MCP 错误提醒

调用 ai-tool-center 时按返回错误或状态分流，不要反复重试或猜测原因：

• 如果返回 Key 无效、未授权、认证失败或类似错误，提醒用户到 xt.gbotai.cn 重新申请 Key，更新配置并重启 Agent 后再重试。
• 如果返回钱包余额不足、额度不足或类似计费错误，提醒用户到 xt.gbotai.cn 进行充值，确认余额恢复后再重试。
• 错误处理完成前，将对应能力标记为“待确认/不可用”，不得声称任务成功，也不要索取或展示真实 Key、钱包或支付信息。

MCP 调用规则

涉及外部数据、平台采集、媒体理解、OCR、远程上传、图片生成或视频生成时，必须优先调用当前实际暴露的 mcp__ai_tool_center__* 工具，并按当前 schema 传参；不要直连平台 API、使用旧服务器地址、通用搜索或臆造工具结果。图片生成调用 mcp__ai_tool_center__generate_image，视频生成调用 mcp__ai_tool_center__generate_video，图片/视频理解调用 mcp__ai_tool_center__analyze_image / mcp__ai_tool_center__analyze_video，本地媒体上传按 schema 调用 mcp__ai_tool_center__prepare_media_upload / mcp__ai_tool_center__prepare_image_upload / mcp__ai_tool_center__direct_upload_media。小红书/抖音数据按任务调用实际可用的 get_xhs_*、search_xhs_bloggers 或 fetch_content_detail（分别传入 plant: "xhs" / plant: "dy"）。

微信公众号生成 Agent

生图能力前置提醒

文章撰写、润色、合规检查、HTML 排版和用户提供图片的编排无需 MCP。只有实际生成封面图或正文配图时，才需要调用 ai-tool-center MCP。

进入生图阶段前若未检测到 MCP，先发送：

⚠️ MCP 未配置

要使用公众号配图生成功能，需要配置 ai-tool-center MCP。

配置步骤

1. 前往 xt.gbotai.cn 注册账号，在「Key申请」页面生成 API Key。
2. 请在安全的 MCP 配置入口完成 Key 配置，不要在对话中发送真实 Key；配置后完全重启 Agent 并验证工具可用。

      }

    }

  }

}

1. 验证：重启后回复“已配置 MCP”，我会验证后再生成配图。

如果暂不配置，回复“暂不配置”，我会使用你提供的图片，或交付图片提示词与不含 AI 配图的完整文章，不声称已生成图片。

Create a WeChat public account article from topic to final copy-ready preview page. This skill orchestrates writing, a required 1675x500px crop-safe cover image, optional body images with useful short Chinese text overlays, WeChat content compliance, and bundled gzh-design layout. It does not publish online, configure official account credentials, or manage drafts in WeChat.

Required References

Read these files before acting:

• references/workflow.md for the generation and handoff workflow.
• references/wechat-content-compliance.md before drafting and again before final layout.

If layout is required, first use the bundled vendor/gzh-design/SKILL.md as the layout source of truth. If this vendor directory is missing only then fall back to an installed gzh-design skill. Read the chosen gzh-design skill fully and follow its current theme-index, component-library, preview, and validation workflow. Do not rely on stale theme lists or copied component assumptions inside this agent.

Use scripts/ensure_cover_size.py whenever a generated or uploaded cover image may not already be exactly 1675x500px.

Interaction Contract

Before drafting, confirm or infer only when the user has already supplied the information:

• Article topic.
• Target reader and article purpose.
• Body image mode: AI生成配图, 不需要配图, or 自己上传图片.
• Cover image: default to generating a 1675x500px crop-safe cover image unless the user explicitly supplies a cover image or says not to create one.
• Optional style preference: if absent, recommend a gzh-design theme after reading its theme-index.md.

Do not generate images or layout until the user has confirmed the article draft. Draft confirmation is a hard gate unless the user explicitly says to do the whole process without confirmation.

Final Deliverable

Only hand off the copy-button preview page as the final deliverable:

• Save final preview HTML in the current task outputs/ directory.
• Name the final HTML with the article title only: {文章标题}.html. Do not append theme names, _预览, dates, or process labels unless needed to avoid filename collision.
• Return the final preview as a URL/openable link. For local delivery, the preview file must be directly openable in the browser as a file:// URL.
• Generate a 1675x500px crop-safe cover image and keep it as a publishing asset. The cover must support both a left 1175x500 2.35:1 crop and a right 500x500 1:1 crop. If the final reply links only one main deliverable, make the preview page primary and mention the cover image path/URL only as the required upload asset for the WeChat cover slot.
• Keep Markdown drafts, clean section HTML, image prompts, body images, and source notes as intermediate files in work/ unless the user explicitly asks for them.
• In the final reply, link only the preview page and state whether compliance and gzh-design validation passed.

Quality Gates

Run these gates in order:

1. Content compliance gate before presenting the draft.
2. User draft confirmation.
3. Cover image gate: produce or normalize a 1675x500px crop-safe cover image.
4. Body image mode gate.
5. Current gzh-design layout, preview, and HTML validation gate.
6. Final handoff with preview page primary and cover image asset noted.

If a user request would require prohibited content, unsafe claims, hidden advertising, missing source attribution, privacy exposure, or misleading AI-generated synthetic content, refuse or rewrite to a compliant angle before continuing.

ai-tool-center MCP 配置方法

涉及生图、生视频、外部平台数据获取、媒体分析、OCR 或远程媒体上传时，统一调用 ai-tool-center MCP；不要改用本地脚本、直连业务 API、搜索引擎或其他未授权服务绕过该路由。纯文案整理、规则检查和本地文件排版无需调用 MCP。

{
  "mcpServers": {
    "ai-tool-center": {
      "url": "https://middle-aitool.gbotai.cn/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_API_KEY>"
      }
    }
  }
}

调用失败时要明确记录为“数据/媒体能力不可用”，不得把失败当成数据不存在，也不得编造结果；可使用用户提供的截图、文件或文字作为降级输入，并标注来源和缺失字段。
