README (SKILL.md)
local-qrcode
Overview
A simple skill for generating QR codes locally. Convert any text or URL to a QR code image (PNG) or display as ASCII art in terminal. Everything runs locally, no external API calls needed.
Features
- Generate PNG QR code: Save QR code as PNG image file
- ASCII QR output: Display QR code directly in terminal as ASCII art
- Customizable: Adjust box size and border size for output
Dependencies
Requires qrcode and Pillow Python packages:
pip install qrcode pillow
Usage
Generate PNG QR code
python3 scripts/generate_png.py "https://example.com" output.png
Generate ASCII QR code
python3 scripts/generate_ascii.py "Hello World"
Custom size
python3 scripts/generate_png.py --box-size 10 --border 4 "content" output.png
Resources
scripts/
generate_png.py- Generate QR code as PNG image filegenerate_ascii.py- Generate QR code as ASCII art for terminal output
Usage Guidance
This skill appears safe and does what it claims, but verify before use: (1) install qrcode and Pillow in a virtualenv (pip install qrcode pillow) to avoid contaminating your system Python; (2) be aware the scripts print the QR content to stdout and will write the PNG to the given path (it can overwrite files); (3) because the source is 'unknown', inspect the two small scripts yourself (they are short and clear) before running; and (4) avoid encoding sensitive secrets into QR codes if you don't want them shown in terminal or written to disk.
Capability Analysis
Type: OpenClaw Skill
Name: local-qrcode
Version: 1.0.0
The skill bundle provides legitimate functionality for generating QR codes locally using the standard 'qrcode' and 'Pillow' Python libraries. Analysis of 'generate_ascii.py' and 'generate_png.py' shows no evidence of data exfiltration, malicious execution, or obfuscation, and the 'SKILL.md' file contains no harmful prompt injection instructions.
Capability Assessment
Purpose & Capability
Name/description (local QR generation) matches the included files and declared dependencies (qrcode, Pillow). No unrelated binaries, services, or credentials are requested.
Instruction Scope
SKILL.md and the scripts limit actions to generating QR codes, printing to stdout, and saving a PNG file. The scripts do not read other files, environment variables, or perform network I/O.
Install Mechanism
No install spec is provided (instruction-only skill). Dependencies are standard Python packages (qrcode, Pillow) which are reasonable for the stated purpose; user must install them via pip or use an environment that already has them.
Credentials
The skill requests no environment variables, credentials, or config paths. The scripts do print the QR content to terminal which is expected but could expose sensitive content if the input is secret.
Persistence & Privilege
always is false and the skill does not request persistent or elevated privileges, nor does it modify agent/system configuration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install local-qrcode - After installation, invoke the skill by name or use
/local-qrcode - Provide required inputs per the skill's parameter spec and get structured output
Version History
