Description
QR code generation and reading. Use when user says "generate QR code", "create QR", "read QR code", or wants to work with QR codes.
Usage Guidance
This skill appears coherent and limited to local QR operations, but before installing consider: 1) Ensure you want files written to the skill/workspace qrcodes directory (the script creates a qrcodes folder at a parent workspace-level). 2) Install the documented dependencies (qrencode, zbar) from trusted package managers. 3) Review the script if you need stricter filesystem controls — it will read any input file you point it at (batch mode) and write PNGs; avoid passing untrusted input. 4) For extra safety, run the script in a sandboxed environment or container if you are cautious. 5) Be aware of cross-platform differences (md5sum may be missing on macOS). If you want me to, I can highlight exact lines in the script to review or suggest a small hardening patch (e.g., restrict output path or sanitize filenames).
Capability Analysis
Type: OpenClaw Skill
Name: qr-code-toolkit
Version: 1.0.0
The qr-code-toolkit skill bundle provides standard functionality for generating and reading QR codes using the 'qrencode' and 'zbarimg' utilities. The shell script (scripts/qr.sh) correctly implements the features described in SKILL.md and README.md, including WiFi and vCard generation, without any evidence of data exfiltration, persistence mechanisms, or malicious intent.
Capability Assessment
Purpose & Capability
Name/description (generate/read QR codes) match the provided script and README. The script relies on qrencode for generation and zbarimg/zbar-tools for reading — these are the expected tools for the stated purpose.
Instruction Scope
Runtime instructions point to the included shell script and only perform local filesystem operations (generate files under a qrcodes directory and read user-supplied images). The script reads an input file for batch operations and writes output PNGs; it does not contact remote endpoints or read unrelated system secrets. Note: the script resolves QR_DIR by moving three levels up from the script directory, which places the qrcodes folder at a workspace/root level (intentional per SKILL.md), and batch uses md5sum for filenames (md5sum may not be present on all platforms).
Install Mechanism
This is an instruction-only skill with no install spec; the README documents installing qrencode and zbar via package managers. No remote downloads or archive extraction are present in the skill bundle.
Credentials
No environment variables or credentials are requested. The script does not access secrets or configuration outside of the user-supplied input files and the filesystem where it writes output.
Persistence & Privilege
always is false and the skill is user-invocable. It does not modify other skills or system-wide agent settings and has no installation hooks that would grant persistent elevated privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install qr-code-toolkit - After installation, invoke the skill by name or use
/qr-code-toolkit - Provide required inputs per the skill's parameter spec and get structured output
