我的二维码生成技能

生成文本、URL或WiFi信息的二维码，支持自定义尺寸、颜色，二维码图片保存到指定路径，默认为桌面。

Security Scan

The skill's code and instructions match its description (generating and saving QR images); the only noteworthy behaviors are runtime pip installation of dependencies and writing files to user-specified paths, both of which are expected for this purpose.

Purpose & Capability

Name/description (generate QR codes, customize size/color, save to path) align with the bundled SKILL.md and agent.py. The code implements generate_qr(text,size,color,save_path) and uses qrcode/Pillow as described—no unrelated services or credentials are requested.

Instruction Scope

SKILL.md and agent.py stay within the stated purpose. The skill writes image files to disk (user-specified path or Desktop) and will create directories if missing — this is necessary for saving output. One minor note: the code reads the USERPROFILE environment variable when choosing the Windows desktop path (os.environ["USERPROFILE"]) but the registry metadata declares no env vars; this is a small implementation detail rather than a scope creep.

Install Mechanism

There is no install spec in the registry; instead agent.py attempts to auto-install missing dependencies at runtime using subprocess.check_call([sys.executable, "-m", "pip", "install", package]). Installing from PyPI at runtime is common but has moderate risk (network fetch, executing package install hooks). This behavior is expected for a Python instruction-only skill but consider pre-installing or pinning versions.

Credentials

The skill does not request credentials or config paths. It does read USERPROFILE (for Windows desktop path) and uses os.path.expanduser on other OSes; this is proportional to the need to compute a default save location. No other environment variables or secrets are accessed or transmitted.

Persistence & Privilege

The skill is user-invocable, not always-enabled, and does not modify other skills or global agent settings. It writes files only to user-specified locations (or default Desktop) and does not request persistent elevated privileges.

Assessment

This skill appears to do what it claims: generate and save QR images. Before installing/using: (1) be aware the Python file will try to pip-install 'qrcode' and 'pillow' at runtime — if you prefer, install these packages yourself in a virtual environment or pin versions; (2) the skill will write files to the path you specify (defaults to your Desktop) and will create directories as needed—avoid giving paths you don't want modified; (3) running code that performs pip installs fetches code from PyPI (network) so run in a controlled environment if you are concerned; (4) if you want extra safety, review the agent.py source locally and run it in a sandboxed/python venv before granting broader access.

Generate QR Code Skill（生成二维码技能）

1. Description

当用户需要将文本、URL、WiFi 信息等转换为可视化二维码时，使用此技能生成二维码图片，并保存到指定路径（默认保存到桌面），支持自定义尺寸和颜色。

2. When to use

• 用户说：“帮我把 https://openclaw.ai 生成二维码”
• 用户说：“生成一个包含 WiFi 信息的二维码，名称：MyWiFi，密码：12345678”
• 用户说：“生成黑色二维码，内容是‘Hello OpenClaw’，保存到 D 盘根目录”
• 用户说：“帮我做一个 400px 大小的二维码，内容是我的手机号 [phone]”

3. How to use

1. 从用户消息中提取核心参数：
   • 必选：生成内容（文本/URL/WiFi 信息，WiFi 格式需为“WIFI:S:名称;T:类型;P:密码;;”）；
   • 可选：尺寸（默认 300px）、颜色（默认黑色）、保存路径（默认桌面）；
2. 若用户未指定可选参数，使用默认值；
3. 调用 agent.py 中的 generate_qr 函数执行生成操作；
4. 返回结果：告知用户二维码保存路径，若生成失败，说明具体原因（如路径无权限、内容为空）。

4. Implementation（代码关联说明）

• 依赖库：qrcode（生成二维码）、Pillow（图片处理）；
• 核心函数：async def generate_qr(text: str, size: int = 300, color: str = "black", save_path: str = None)；
• 参数说明：
  • text：二维码内容（必选）；
  • size：二维码尺寸（单位 px，默认 300）；
  • color：填充颜色（默认 black，支持英文颜色名或十六进制色值，如 #FF0000）；
  • save_path：保存路径（默认桌面，文件名：qr_code.png）。

5. Edge cases

• 内容为空：回复“请提供需要生成二维码的内容（如文本、URL、WiFi 信息）”；
• 保存路径无权限：回复“指定路径无写入权限，请更换保存路径（如桌面）”；
• 未安装依赖库：自动尝试安装 qrcode 和 Pillow，若安装失败，提示用户手动执行“pip install qrcode pillow”；
• 特殊字符内容：自动过滤无效字符，确保二维码可正常识别。
