/install qrcode2
Description
本地将文本/URL 编成 PNG 二维码，或从图片识别二维码，可与远程 qrcode 技能搭配。当用户说：本地生成二维码图片、离线扫图读码，或类似本地二维码问题时，使用本技能。
Usage Guidance
This skill appears to do exactly what it claims: generate and decode QR codes locally. Before installing or running it, install the recommended Python packages from a trusted source (pip install "qrcode[pil]" opencv-python), and run the script in a directory where writing image files is acceptable. Note the script writes/reads files relative to the current working directory (absolute paths are blocked). The provided qrcode.py file appears duplicated/truncated in the package listing — consider fetching a clean, single-copy version from a trusted repository or asking the publisher to confirm the file integrity before use.
Capability Analysis
Type: OpenClaw Skill
Name: qrcode2
Version: 1.0.4
The qrcode2 skill provides local QR code generation and decoding functionality using the 'qrcode' and 'opencv-python' libraries. The implementation in qrcode.py includes a security-conscious path normalization function (_normalize_local_path) that prevents directory traversal and restricts file operations to the current working directory. No malicious behaviors, data exfiltration, or suspicious network activities were found.
Capability Assessment
Purpose & Capability
Name/description request Python and local QR libraries only; the code imports qrcode and opencv (cv2) and performs only encode/decode operations. No unrelated credentials, binaries, or services are required.
Instruction Scope
SKILL.md instructs running the included Python script with JSON args; the script only reads/writes files within the current working directory (it enforces no absolute paths and blocks leading '..'). This stays within the stated purpose. Note: the skill writes output files to the working directory and will read any image file path you provide, so choose the working directory carefully.
Install Mechanism
There is no install spec; SKILL.md suggests installing dependencies via pip (qrcode[pil], opencv-python). No external downloads or opaque install URLs are used.
Credentials
The skill requests no environment variables or credentials. Its dependency needs (Python packages) are proportional to QR generation/recognition.
Persistence & Privilege
Skill is not always-enabled and is user-invocable. It does not modify other skills or system configuration; it only reads/writes files under the agent's working directory.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install qrcode2 - After installation, invoke the skill by name or use
/qrcode2 - Provide required inputs per the skill's parameter spec and get structured output
