Download\n\nThis skill guides you on how to resolve a TikTok video URL into direct download and playback links, helping sellers save influencer/promotional video assets for offline analysis or reuse.\n\n## Core Concepts\n\nThis tool takes a single TikTok video URL and resolves it to direct media addresses: a no-watermark download URL (preferred for clean assets), a watermarked download URL, a playback URL, and cover images (static and dynamic). This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\n\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\n- Short link: `https://vt.tiktok.com/xxxxxx`\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\n\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\n\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\n\n## Parameter Guide\n\n| Parameter | Type | Required | Description | Default |\n|-----------|------|----------|-------------|---------|\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\n\n## 调用方式\n\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\n- **成本约束**：本工具会消耗算力；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\n\n**输出策略（脚本默认行为）**：\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\n\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\n\n## 解决认证和算力问题\n发生以下异常情况时，采用 references/onboarding.md 引导解决问题：\n\n### 异常情况\n- **未配置API Key**：环境变量未配置 `LINKFOX_AGENT_API_KEY`，也未配置 `LINKFOXAGENT_API_KEY`。\n- **响应401或402状态码**\n- **响应提示算力或余额不足**：消息含\"算力余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值\"，或类似含义的内容。\n\n## Usage Examples\n\n**1. Resolve a full TikTok video link**\n```json\n{\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\n}\n```\n\n**2. Resolve a TikTok short link**\n```json\n{\n \"url\": \"https://vt.tiktok.com/Z123abc/\"\n}\n```\n\n## Display Rules\n\n1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want\n2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding\n3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link — tell the user the video has no direct download address and offer `playUrl` for playback/preview instead\n4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails\n5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly\n6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video\n7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` — `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format\n\n## User Expression & Scenario Quick Reference\n\n### Applicable Scenarios\n\n| User Says | Scenario |\n|-----------|----------|\n| \"Download this TikTok video\" / \"Save this TikTok clip\" | Resolve a video URL into download links |\n| \"Get the no-watermark version of this TikTok video\" | Prioritize `noWatermarkDownloadUrl` |\n| \"I want to save this influencer's promo video\" | Resolve and archive a creator's video |\n| \"Give me a playable link for this TikTok video\" | Return `playUrl` |\n| \"Get the cover/thumbnail of this TikTok video\" | Return `coverUrl` / `dynamicCoverUrl` |\n\n### Not Applicable Scenarios\n\n- Listing promotional videos associated with a TikTok **product** (use `linkfox-echotik-product-video` instead — it needs a `productId`, not a video URL)\n- Searching for TikTok products (use `linkfox-echotik-product-search`)\n- TikTok new product rankings (use `linkfox-echotik-new-product-rank`)\n- TikTok live-stream data\n- Video editing or content creation advice\n- Non-TikTok platform video downloads\n\n### Boundary Judgment\n\nWhen users mention \"TikTok video\", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product-video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\n\n## 算力消耗规则\n\n消耗 5 算力。\n\n> 用户会因算力消耗而支付费用。请充分评估：当需要高频调用本技能，或用户对算力消耗量预期不足时，务必提醒用户，由用户决定是否继续。\n\n**Feedback:**\n\nAuto-detect and report feedback via the Feedback API when any of the following apply:\n1. The functionality or purpose described in this skill does not match actual behavior\n2. The skill's results do not match the user's intent\n3.

This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\n\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\n- Short link: `https://vt.tiktok.com/xxxxxx`\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\n\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\n\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\n\n## Parameter Guide\n\n| Parameter | Type | Required | Description | Default |\n|-----------|------|----------|-------------|---------|\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\n\n## 调用方式\n\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\n- **成本约束**：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\n\n**输出策略（脚本默认行为）**：\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\n\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\n\n## 解决认证和积分问题\n发生以下异常情况时，采用 references/onboarding.md 引导解决问题：\n\n### 异常情况\n- **未配置API Key**：环境变量未配置 `LINKFOX_AGENT_API_KEY`，也未配置 `LINKFOXAGENT_API_KEY`。\n- **响应401或402状态码**\n- **响应提示积分或余额不足**：消息含\"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值\"，或类似含义的内容。\n\n## Usage Examples\n\n**1. Resolve a full TikTok video link**\n```json\n{\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\n}\n```\n\n**2. Resolve a TikTok short link**\n```json\n{\n \"url\": \"https://vt.tiktok.com/Z123abc/\"\n}\n```\n\n## Display Rules\n\n1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want\n2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding\n3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link — tell the user the video has no direct download address and offer `playUrl` for playback/preview instead\n4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails\n5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly\n6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video\n7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` — `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format\n\n## User Expression & Scenario Quick Reference\n\n### Applicable Scenarios\n\n| User Says | Scenario |\n|-----------|----------|\n| \"Download this TikTok video\" / \"Save this TikTok clip\" | Resolve a video URL into download links |\n| \"Get the no-watermark version of this TikTok video\" | Prioritize `noWatermarkDownloadUrl` |\n| \"I want to save this influencer's promo video\" | Resolve and archive a creator's video |\n| \"Give me a playable link for this TikTok video\" | Return `playUrl` |\n| \"Get the cover/thumbnail of this TikTok video\" | Return `coverUrl` / `dynamicCoverUrl` |\n\n### Not Applicable Scenarios\n\n- Listing promotional videos associated with a TikTok **product** (use `linkfox-echotik-product-video` instead — it needs a `productId`, not a video URL)\n- Searching for TikTok products (use `linkfox-echotik-product-search`)\n- TikTok new product rankings (use `linkfox-echotik-new-product-rank`)\n- TikTok live-stream data\n- Video editing or content creation advice\n- Non-TikTok platform video downloads\n\n### Boundary Judgment\n\nWhen users mention \"TikTok video\", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product-video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\n\n## 积分消耗规则\n\n消耗 5 积分。\n\n> 用户会因积分消耗而支付费用。请充分评估：当需要高频调用本技能，或用户对积分消耗量预期不足时，务必提醒用户，由用户决定是否继续。\n\n**Feedback:**\n\nAuto-detect and report feedback via the Feedback API when any of the following apply:\n1.

This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\n\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\n- Short link: `https://vt.tiktok.com/xxxxxx`\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\n\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\n\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\n\n## Parameter Guide\n\n| Parameter | Type | Required | Description | Default |\n|-----------|------|----------|-------------|---------|\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\n\n## 调用方式\n\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\n- **成本约束**：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\n\n**输出策略（脚本默认行为）**：\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\n\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\n\n## 解决认证和积分问题\n发生以下异常情况时，采用 references/onboarding.md 引导解决问题：\n\n### 异常情况\n- **未配置API Key**：环境变量未配置 `LINKFOX_AGENT_API_KEY`，也未配置 `LINKFOXAGENT_API_KEY`。\n- **响应401或402状态码**\n- **响应提示积分或余额不足**：消息含\"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值\"，或类似含义的内容。\n\n## Usage Examples\n\n**1. Resolve a full TikTok video link**\n```json\n{\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\n}\n```\n\n**2. Resolve a TikTok short link**\n```json\n{\n \"url\": \"https://vt.tiktok.com/Z123abc/\"\n}\n```\n\n## Display Rules\n\n1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want\n2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding\n3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link — tell the user the video has no direct download address and offer `playUrl` for playback/preview instead\n4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails\n5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly\n6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video\n7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` — `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format\n\n## User Expression & Scenario Quick Reference\n\n### Applicable Scenarios\n\n| User Says | Scenario |\n|-----------|----------|\n| \"Download this TikTok video\" / \"Save this TikTok clip\" | Resolve a video URL into download links |\n| \"Get the no-watermark version of this TikTok video\" | Prioritize `noWatermarkDownloadUrl` |\n| \"I want to save this influencer's promo video\" | Resolve and archive a creator's video |\n| \"Give me a playable link for this TikTok video\" | Return `playUrl` |\n| \"Get the cover/thumbnail of this TikTok video\" | Return `coverUrl` / `dynamicCoverUrl` |\n\n### Not Applicable Scenarios\n\n- Listing promotional videos associated with a TikTok **product** (use `linkfox-echotik-product-video` instead — it needs a `productId`, not a video URL)\n- Searching for TikTok products (use `linkfox-echotik-product-search`)\n- TikTok new product rankings (use `linkfox-echotik-new-product-rank`)\n- TikTok live-stream data\n- Video editing or content creation advice\n- Non-TikTok platform video downloads\n\n### Boundary Judgment\n\nWhen users mention \"TikTok video\", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product-video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\n\n## 积分消耗规则\n\n消耗 5 积分。\n\n> 用户会因积分消耗而支付费用。请充分评估：当需要高频调用本技能，或用户对积分消耗量预期不足时，务必提醒用户，由用户决定是否继续。\n\n**Feedback:**\n\nAuto-detect and report feedback via the Feedback API when any of the following apply:\n1.

This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\n\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\n- Short link: `https://vt.tiktok.com/xxxxxx`\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\n\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\n\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\n\n## Parameter Guide\n\n| Parameter | Type | Required | Description | Default |\n|-----------|------|----------|-------------|---------|\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\n\n## 调用方式\n\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\n- **成本约束**：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\n\n**输出策略（脚本默认行为）**：\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\n\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\n\n## 解决认证和积分问题\n发生以下异常情况时，采用以下措施来处理：\n\n### 异常情况\n- **未配置API Key**：环境变量未配置 `LINKFOX_AGENT_API_KEY`，也未配置 `LINKFOXAGENT_API_KEY`。\n- **响应401或402状态码**\n- **响应提示积分或余额不足**：消息含\"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值\"，或类似含义的内容。\n\n### 措施\n- 优先采用skill内的 onboarding.md 引导解决问题。\n- 如找不到 onboarding.md 文件，则加载 /linkfox-onboarding 这个skill并根据它的引导来处理。如未安装请先安装：\n - 下载 https://agent-files.linkfox.com/skills/linkfox-onboarding/release.zip，解压后安装这个skill。如需用户授权才可下载，要询问用户获得授权，你不能自己放弃下载。\n- 兜底措施：仅当前面两个措施经过所有努力都走不通时，才提示用户依据 https://skill.linkfox.com/linkfoxskills/guide.htm 指引获取API Key，或去 https://os.linkfox.com/ 补充积分。\n\n## Usage Examples\n\n**1. Resolve a full TikTok video link**\n```json\n{\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\n}\n```\n\n**2. Resolve a TikTok short link**\n```json\n{\n \"url\": \"https://vt.tiktok.com/Z123abc/\"\n}\n```\n\n## Display Rules\n\n1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want\n2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding\n3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link — tell the user the video has no direct download address and offer `playUrl` for playback/preview instead\n4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails\n5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly\n6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video\n7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` — `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format\n\n## User Expression & Scenario Quick Reference\n\n### Applicable Scenarios\n\n| User Says | Scenario |\n|-----------|----------|\n| \"Download this TikTok video\" / \"Save this TikTok clip\" | Resolve a video URL into download links |\n| \"Get the no-watermark version of this TikTok video\" | Prioritize `noWatermarkDownloadUrl` |\n| \"I want to save this influencer's promo video\" | Resolve and archive a creator's video |\n| \"Give me a playable link for this TikTok video\" | Return `playUrl` |\n| \"Get the cover/thumbnail of this TikTok video\" | Return `coverUrl` / `dynamicCoverUrl` |\n\n### Not Applicable Scenarios\n\n- Listing promotional videos associated with a TikTok **product** (use `linkfox-echotik-product-video` instead — it needs a `productId`, not a video URL)\n- Searching for TikTok products (use `linkfox-echotik-product-search`)\n- TikTok new product rankings (use `linkfox-echotik-new-product-rank`)\n- TikTok live-stream data\n- Video editing or content creation advice\n- Non-TikTok platform video downloads\n\n### Boundary Judgment\n\nWhen users mention \"TikTok video\", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product-video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\n\n## 积分消耗规则\n\n消耗 4.5 积分。\n\n> 用户会因积分消耗而支付费用。请充分评估：当需要高频调用本技能，或用户对积分消耗量预期不足时，务必提醒用户，由用户决定是否继续。\n\n**Feedback:**\n\nAuto-detect and report feedback via the Feedback API when any of the following apply:\n1.

\nMitigation: Confirm the user has configured an appropriate LinkFox API key, explain credit consumption before repeated calls, and avoid speculative retries without user approval.
\nRisk: The skill saves full API responses locally, which can retain TikTok URLs and returned media links.
\nMitigation: Tell users where responses are stored and clean the local LinkFox cache or result files when retained data is no longer needed.
\nRisk: The security review flags external feedback reporting and a fallback install/download path as behavior users should review before installing.
\nMitigation: Review the feedback flow and onboarding fallback before use, and avoid automatic feedback reporting unless it is acceptable for the user's data handling requirements.

This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\r\n\r\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\r\n- Short link: `https://vt.tiktok.com/xxxxxx`\r\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\r\n\r\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\r\n\r\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\r\n\r\n## Parameter Guide\r\n\r\n| Parameter | Type | Required | Description | Default |\r\n|-----------|------|----------|-------------|---------|\r\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\r\n\r\n## 调用方式\r\n\r\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\r\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\r\n- **成本约束**：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\r\n\r\n**输出策略（脚本默认行为）**：\r\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\r\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\r\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\r\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\r\n\r\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\r\n\r\n## Usage Examples\r\n\r\n**1. Resolve a full TikTok video link**\r\n```json\r\n{\r\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\r\n}\r\n```\r\n\r\n**2. Resolve a TikTok short link**\r\n```json\r\n{\r\n \"url\": \"https://vt.tiktok.com/Z123abc/\"\r\n}\r\n```\r\n\r\n## Display Rules\r\n\r\n1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want\r\n2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding\r\n3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link — tell the user the video has no direct download address and offer `playUrl` for playback/preview instead\r\n4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails\r\n5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly\r\n6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video\r\n7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` — `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format\r\n\r\n## User Expression & Scenario Quick Reference\r\n\r\n### Applicable Scenarios\r\n\r\n| User Says | Scenario |\r\n|-----------|----------|\r\n| \"Download this TikTok video\" / \"Save this TikTok clip\" | Resolve a video URL into download links |\r\n| \"Get the no-watermark version of this TikTok video\" | Prioritize `noWatermarkDownloadUrl` |\r\n| \"I want to save this influencer's promo video\" | Resolve and archive a creator's video |\r\n| \"Give me a playable link for this TikTok video\" | Return `playUrl` |\r\n| \"Get the cover/thumbnail of this TikTok video\" | Return `coverUrl` / `dynamicCoverUrl` |\r\n\r\n### Not Applicable Scenarios\r\n\r\n- Listing promotional videos associated with a TikTok **product** (use `linkfox-echotik-product-video` instead — it needs a `productId`, not a video URL)\r\n- Searching for TikTok products (use `linkfox-echotik-product-search`)\r\n- TikTok new product rankings (use `linkfox-echotik-new-product-rank`)\r\n- TikTok live-stream data\r\n- Video editing or content creation advice\r\n- Non-TikTok platform video downloads\r\n\r\n### Boundary Judgment\r\n\r\nWhen users mention \"TikTok video\", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product-video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\r\n\r\n\r\n**Feedback:**\r\n\r\nAuto-detect and report feedback via the Feedback API when any of the following apply:\r\n1. The functionality or purpose described in this skill does not match actual behavior\r\n2. The skill's results do not match the user's intent\r\n3. The user expresses dissatisfaction or praise about this skill\r\n4. Anything you believe could be improved\r\n\r\nCall the feedback API as specified in `references/api.md`.

This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\r\n\r\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\r\n- Short link: `https://vt.tiktok.com/xxxxxx`\r\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\r\n\r\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\r\n\r\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\r\n\r\n## Parameter Guide\r\n\r\n| Parameter | Type | Required | Description | Default |\r\n|-----------|------|----------|-------------|---------|\r\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\r\n\r\n## 调用方式\r\n\r\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\r\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\r\n- **成本约束**：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\r\n\r\n**输出策略（脚本默认行为）**：\r\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\r\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\r\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\r\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\r\n\r\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\r\n\r\n## Usage Examples\r\n\r\n**1. Resolve a full TikTok video link**\r\n```json\r\n{\r\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\r\n}\r\n```\r\n\r\n**2. Resolve a TikTok short link**\r\n```json\r\n{\r\n \"url\": \"https://vt.tiktok.com/Z123abc/\"\r\n}\r\n```\r\n\r\n## Display Rules\r\n\r\n1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want\r\n2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding\r\n3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link — tell the user the video has no direct download address and offer `playUrl` for playback/preview instead\r\n4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails\r\n5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly\r\n6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video\r\n7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` — `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format\r\n\r\n## User Expression & Scenario Quick Reference\r\n\r\n### Applicable Scenarios\r\n\r\n| User Says | Scenario |\r\n|-----------|----------|\r\n| \"Download this TikTok video\" / \"Save this TikTok clip\" | Resolve a video URL into download links |\r\n| \"Get the no-watermark version of this TikTok video\" | Prioritize `noWatermarkDownloadUrl` |\r\n| \"I want to save this influencer's promo video\" | Resolve and archive a creator's video |\r\n| \"Give me a playable link for this TikTok video\" | Return `playUrl` |\r\n| \"Get the cover/thumbnail of this TikTok video\" | Return `coverUrl` / `dynamicCoverUrl` |\r\n\r\n### Not Applicable Scenarios\r\n\r\n- Listing promotional videos associated with a TikTok **product** (use `linkfox-echotik-product-video` instead — it needs a `productId`, not a video URL)\r\n- Searching for TikTok products (use `linkfox-echotik-product-search`)\r\n- TikTok new product rankings (use `linkfox-echotik-new-product-rank`)\r\n- TikTok live-stream data\r\n- Video editing or content creation advice\r\n- Non-TikTok platform video downloads\r\n\r\n### Boundary Judgment\r\n\r\nWhen users mention \"TikTok video\", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product-video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\r\n\r\n\r\n**Feedback:**\r\n\r\nAuto-detect and report feedback via the Feedback API when any of the following apply:\r\n1. The functionality or purpose described in this skill does not match actual behavior\r\n2. The skill's results do not match the user's intent\r\n3.

If they mention a product ID and ask \"what videos promote this product\", use `linkfox-echotik-product-video` instead.\r\n\r\n\r\n**Feedback:**\r\n\r\nAuto-detect and report feedback via the Feedback API when any of the following apply:\r\n1. The functionality or purpose described in this skill does not match actual behavior\r\n2. The skill's results do not match the user's intent\r\n3. The user expresses dissatisfaction or praise about this skill\r\n4. Anything you believe could be improved\r\n\r\nCall the feedback API as specified in `references/api.md`. Do not interrupt the user's flow.\r\n\r\n\r\n## Handling Large Responses\r\n\r\nTo avoid overflowing the agent context, persist the response to disk and extract only the fields you need:\r\n\r\n```\r\npython scripts/response_io.py run --script scripts/echotik_get_video_download_url.py --out-dir ''\r\npython scripts/response_io.py read --fields \"\" # or --path \"\"\r\n```\r\n\r\n> Pick `--out-dir` outside any git working tree (e.g. `/tmp/...` on Unix, `%TEMP%/...` on Windows). Persisted responses may contain PII, pricing, or auth-sensitive data — do not commit them. Files are not auto-deleted; clean up when the task is done.\r\n\r\n`run` writes the full response to a file and emits only a schema preview + file path. `read` projects specific fields, with `--limit/--offset` for slicing and `--format json|jsonl|csv|table` for output.\r\n\r\n**When to prefer this pattern** — apply your judgment based on the response characteristics, e.g.:\r\n- High field count per record, or fields you don't need\r\n- Batch/paginated results (multiple items per call)\r\n- Long-text fields (descriptions, reviews, HTML, time series)\r\n- Output reused across later steps rather than consumed immediately\r\n\r\nFor small, single-use responses, calling the main script directly is fine.\r\n\r\n⚠️ The preview is a truncated schema + sample, not the full data. Any field-level decision must read from the persisted file via `read`.\r\n\r\n\r\n---\r\n*For more high-quality, professional cross-border e-commerce skills, visit [LinkFox Skills](https://skill.linkfox.com/).*\n\nFile v1.0.0:_meta.json\n\n{\n \"ownerId\": \"kn7dmc1t4j28hem1twwyav85p182pb1j\",\n \"slug\": \"linkfox-echotik-get-video-download-url\",\n \"version\": \"1.0.0\",\n \"publishedAt\": 1782719604131\n}\n\nFile v1.0.0:references/api.md\n\n# EchoTik TikTok 视频下载 API 参考\n\n## 调用规范\n\n- **请求地址**：`https://tool-gateway.linkfox.com/echotik/getVideoDownloadUrl`\n- **请求方式**：POST，Content-Type: application/json\n- **认证方式**：Header `Authorization: `，api_key 从环境变量 `LINKFOXAGENT_API_KEY` 读取（如未配置，提示用户前往 https://skill.linkfox.com/linkfoxskills/guide.htm 申请）\n\n## 请求参数\n\nPOST Body（JSON）：\n\n| 参数 | 类型 | 必填 | 说明 |\n|------|------|------|------|\n| url | string | 是 | TikTok 视频地址，支持两种格式：`https://vt.tiktok.com/xxx` 短链或 `https://www.tiktok.com/@user/video/xxx` 完整链接。最大长度 1000 |\n\n## 响应结构\n\n成功时 HTTP 状态码为 200，响应体顶层同时包含业务码 `errcode=200`、`errmsg=\"ok\"` 与下列数据字段。\n\n| 字段 | 类型 | 是否必返 | 说明 |\n|------|------|----------|------|\n| noWatermarkDownloadUrl | string | 条件返回 | 视频下载地址（无水印）。**并非所有视频都返回**：部分视频该字段缺省，此时无法提供无水印下载 |\n| downloadUrl | string | 条件返回 | 视频下载地址（含水印）。**并非所有视频都返回**：与无水印地址一同缺省或出现 |\n| playUrl | string | 始终返回 | 视频播放地址。当下载地址缺省时，可作为播放/预览的兜底 |\n| coverUrl | string | 始终返回 | 视频封面地址（静态） |\n| dynamicCoverUrl | string | 始终返回 | 视频动态封面地址 |\n| videoId | string | 始终返回 | 视频 ID |\n| columns | array | 始终返回 | 渲染列定义（字段元数据：field/title/cellType/filterable/sortable，供前端表格渲染用） |\n| type | string | 始终返回 | 渲染样式（如 `tableListWorkbenches`） |\n| costToken | integer | 始终返回 | 消耗 token |\n| errcode | integer | 始终返回 | 业务码，200 表示成功 |\n| errmsg | string | 始终返回 | 业务信息，成功时为 `ok` |\n\n> **下载地址缺省说明**：实测部分视频（受区域、隐私或源站限制）不会返回 `noWatermarkDownloadUrl` / `downloadUrl`，仅返回 `playUrl` 与封面。此时应向用户说明该视频暂无可直接下载地址，可改用 `playUrl` 播放预览。\n\n成功响应示例（真实调用，已截断长 URL）：\n\n```json\n{\n \"errcode\": 200,\n \"errmsg\": \"ok\",\n \"videoId\": \"7096674515245206810\",\n \"noWatermarkDownloadUrl\": \"https://v45.tiktokcdn-eu.com/51678f6e0de3...\",\n \"downloadUrl\": \"https://v45.tiktokcdn-eu.com/626c5d3d5a7d...\",\n \"playUrl\": \"https://v45.tiktokcdn-eu.com/51678f6e0de3...\",\n \"coverUrl\": \"https://agent-files.linkfox.com/tiktok/20260629/7096674515245206810.jpg\",\n \"dynamicCoverUrl\": \"https://p16-common-sign.tiktokcdn-eu.com/tos-useast2a-p-0037...\",\n \"type\": \"tableListWorkbenches\",\n \"costToken\": 12000,\n \"columns\": [/* 渲染列定义 */]\n}\n```\n\n## 错误码\n\n正常情况下，接口的 HTTP 状态码均为 200，业务的成功与否通过响应体中的 `errcode` 字段区分（`errcode = 200` 表示成功，其他值表示业务错误）。当遇到未授权等情况时，HTTP 状态码为 401，且对应的 `errcode` 也是 401。\n\n| errcode | 含义 | 处理建议 |\n|---------|------|----------|\n| 200 | 成功 | 正常解析业务字段 |\n| 400 | 参数错误 | `errmsg` 会指明缺失项，如 `url 为必填参数`；检查 `url` 是否传入且非空 |\n| 401 | 认证失败 | 检查请求头 `Authorization` 是否正确携带 API Key；API Key 申请方式请参考上述[调用规范](#调用规范)下的认证方式。|\n| 10000 | 未获取到视频下载地址 | URL 非 TikTok 视频链接、视频不可访问或已被删除；提示用户检查链接是否为有效的 TikTok 视频地址 |\n| 其他非200值 | 业务异常 | 参考 `errmsg` 字段获取具体错误原因 |\n\n错误响应示例：\n\n```json\n// 参数缺失\n{\n \"errcode\": 400,\n \"errmsg\": \"url 为必填参数\",\n \"url\": \"\"\n}\n\n// 非有效 TikTok 视频链接\n{\n \"errcode\": 10000,\n \"errmsg\": \"未获取到视频下载地址\"\n}\n\n// 未授权\n{\n \"errcode\": 401,\n \"errmsg\": \"authorized error\"\n}\n```\n\n## curl 示例\n\n```bash\ncurl -X POST https://tool-gateway.linkfox.com/echotik/getVideoDownloadUrl \\\n -H \"Authorization: $LINKFOXAGENT_API_KEY\" \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"url\": \"https://www.tiktok.com/@user/video/1234567890\"\n }'\n```\n\n---\n\n## Feedback API\n\n> This endpoint is **separate** from the tool API above.

This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.\n\n**Required input**: A `url` is mandatory. Two URL formats are accepted:\n- Short link: `https://vt.tiktok.com/xxxxxx`\n- Full link: `https://www.tiktok.com/@user/video/1234567890`\n\n**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.\n\n**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.\n\n## Parameter Guide\n\n| Parameter | Type | Required | Description | Default |\n|-----------|------|----------|-------------|---------|\n| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |\n\n## 调用方式\n\n- **API 端点**：`POST /echotik/getVideoDownloadUrl`（完整参数/响应/错误码见 `references/api.md`）\n- **Python 脚本**：`python scripts/echotik_get_video_download_url.py '' [--inline]`\n- **成本约束**：本工具会消耗算力；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。\n\n**输出策略（脚本默认行为）**：\n- **始终**将完整响应写入 `/linkfox///data/linkfox-echotik-get-video-download-url-.json`（`` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）\n- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout\n- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）\n- 加 `--inline` 强制全量打印到 stdout（同样落盘）\n\n**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。\n\n## 解决认证和算力问题\n发生以下异常情况时，采用 references/onboarding.md 引导解决问题：\n\n### 异常情况\n- **未配置API Key**：环境变量未配置 `LINKFOX_AGENT_API_KEY`，也未配置 `LINKFOXAGENT_API_KEY`。\n- **响应401或402状态码**\n-
