Forum Downloader

从论坛帖子批量下载图片/视频到指定目录。支持需要代理访问的论坛（如 hjd2048），自动提取页面标题创建文件夹，PowerShell 脚本，UTF-8 BOM 编码。

Security Scan

The skill's requirements and instructions match its stated purpose (PowerShell-based forum downloader); no unrelated credentials or installs are requested, but pay attention to file-path handling and what you ask it to download.

Purpose & Capability

Name/description (bulk download images/videos from forum posts via proxy, PowerShell script, GBK handling) align with declared requirement of the powershell binary and the described PowerShell WebClient/WebProxy approach. No unrelated binaries, env vars, or config paths are requested.

Instruction Scope

SKILL.md stays focused on fetching pages via a user-provided proxy, parsing titles, and downloading media with PowerShell. However it instructs creating folders from page titles and writing files to a user-specified directory but does not mention filename/path sanitization, overwrite protection, size limits, or content validation. That omission increases risk (e.g., filenames with traversal characters, overwriting important files, or downloading unwanted/malicious content).

Install Mechanism

Instruction-only skill with no install spec and no external downloads — lowest-risk delivery model. Requiring an existing powershell binary is reasonable for a PowerShell script.

Credentials

No environment variables, credentials, or config paths are requested. The skill asks the user at run-time for a proxy address (not hard-coded) which is proportionate to the described proxy use-case.

Persistence & Privilege

always is false and the skill does not request persistent/system-wide changes. It will write files to directories the user specifies, which is expected behavior for a downloader but means the user should avoid sensitive system paths.

Assessment

This skill appears coherent for downloading forum images/videos using PowerShell. Before installing or running it: (1) only provide proxies you trust (the skill will use whatever proxy you give it); (2) avoid pointing the downloader at sensitive system directories—give an explicit safe folder; (3) ask whether the implementation sanitizes page titles and filenames (to prevent directory traversal or invalid characters) and whether it prevents overwriting files; (4) be cautious about legal/copyright or malware risks from downloaded content; and (5) if you need stronger guarantees, request that the skill include filename sanitization, file-size limits, content-type checks, and a dry-run mode that lists files before downloading.

从论坛帖子批量下载图片或视频，保存到用户指定目录。

适用场景

• hjd2048、2048 等需要代理访问的论坛
• 帖子内含多张图片或附件视频
• 自动用页面标题创建文件夹

使用方式

提供论坛帖子 URL，我会自动：

1. 通过代理获取页面内容
2. 用 GBK/GB2312 编码正确提取标题
3. 在用户指定目录下创建 {标题} 文件夹
4. 解析页面中的图片/附件 URL
5. 用 PowerShell WebClient 下载全部文件

技术细节

• 下载方式：System.Net.WebClient + WebProxy
• 脚本编码：UTF-8 with BOM（解决 PowerShell 中文路径变量问题）
• 编码处理：论坛页面用 GBK 编码读取
• 代理地址：从用户处获取（不硬编码）

示例

用户说 "下载到 D:\图片，使用 XXX 端口的代理"：

1. 创建目录：D:\图片\{页面标题}\
2. 用用户提供的代理地址获取页面
3. 解析图片 URL（data-original 属性）
4. 批量下载

常见问题

Q: 代理端口不是 7890？ → 告诉我实际的代理地址和端口。

Q: 图片是其他格式（jpeg/gif/webp）？ → 脚本中用正则匹配所有图片扩展名，自动处理。

Q: 想下载视频而不是图片？ → 同样适用，只需提供视频帖子的 URL。
