Description
Generate QR codes from text, URLs, WiFi credentials, vCards, or any data. Use when the user wants to create a QR code, share a link as a scannable code, gene...
Usage Guidance
This skill appears to do exactly what it claims (generate QR codes) and includes a small Python script. Before using: (1) be aware the script will run pip install qrcode[pil] if the package is missing — this performs network downloads and installs into your Python environment (run it in a virtualenv if you prefer isolation); (2) inspect/verify the qrcode package on PyPI if you have supply-chain concerns; (3) remember any WiFi password or contact info you encode will be visible to anyone who scans or sees the generated image; and (4) the script will overwrite files at the given output path, so avoid paths you can't afford to replace.
Capability Analysis
Type: OpenClaw Skill
Name: qr-gen
Version: 1.1.0
The `scripts/generate_qr.py` file contains two significant vulnerabilities. Firstly, it uses `subprocess.check_call` to install dependencies, which, while hardcoded to a legitimate package here, represents a powerful primitive that could lead to Remote Code Execution if the arguments were ever derived from untrusted input. Secondly, the script allows writing to arbitrary file paths via the `-o` argument without proper sanitization, creating a path traversal/arbitrary file write vulnerability. There is no clear evidence of intentional malicious behavior such as data exfiltration or backdoor installation, but these are serious flaws that could be exploited.
Capability Assessment
Purpose & Capability
The name/description match the included Python script and examples. There are no unrelated environment variables, binaries, or config paths requested; required capabilities are proportional to a QR generator.
Instruction Scope
SKILL.md instructs the agent to run the bundled script with explicit arguments and examples (URLs, WiFi strings, vCards, ASCII, PNG, SVG). The instructions do not ask the agent to read unrelated files, environment variables, or transmit data to external endpoints. Note: the script will install a Python package at runtime if missing (network activity to PyPI).
Install Mechanism
There is no install spec in the registry (instruction-only), which is low-risk. The included script calls pip to auto-install the qrcode[pil] package if missing; this is a common pattern but does perform network downloads and executes package install steps in the runtime environment (moderate supply-chain risk).
Credentials
The skill requests no environment variables, credentials, or config paths. The WiFi/password and vCard data are provided as command-line args or data strings and are encoded only into the QR output; no other secrets are requested or accessed.
Persistence & Privilege
The skill is not forced-always, is user-invocable, and does not modify other skills or global agent configuration. It does not request elevated or persistent privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install qr-gen - After installation, invoke the skill by name or use
/qr-gen - Provide required inputs per the skill's parameter spec and get structured output
