Description
Generate styled QR images/cards for ClawHub skills so users can scan and install instantly. Supports install-command payloads, ClawHub links, and GitHub link...
Usage Guidance
This skill appears coherent and does what it claims, but check a few operational points before running: (1) Ensure your environment has Node and the 'qrcode' npm package (the repo does not declare an install step); (2) ImageMagick's 'convert' is optionally executed to create PNGs — verify you trust the 'convert' binary on the host; (3) The script writes files under ./images/ (it may overwrite similarly named files); (4) If you copy this into an automated agent, ensure the agent only supplies intended slugs/flags (the script will embed whatever you pass into the QR payload). If you want extra caution, run the script in a sandbox or container and review/lock the 'convert' binary before allowing automated invocation.
Capability Analysis
Type: OpenClaw Skill Name: skill-qr-card Version: 0.1.2 The script `scripts/generate_qr_card.js` contains a shell injection vulnerability where the `--out` command-line argument is passed unsanitized into an `execSync` call to ImageMagick's `convert` utility. While this allows for potential Remote Code Execution (RCE) if an attacker can influence the output filename, there is no evidence of intentional malice or self-exploitation, qualifying it as a critical vulnerability rather than malware.
Capability Assessment
Purpose & Capability
Name/description align with requested files and actions. The included script generates QR payloads for install/ClawHub/GitHub links and produces SVG (and optional PNG) outputs — all expected for a 'QR card' generator.
Instruction Scope
SKILL.md instructs the agent to run the bundled script with CLI flags and to return generated image paths. The script only reads CLI args, writes files under ./images/, and optionally invokes ImageMagick; it does not read other config files, environment variables, or network endpoints.
Install Mechanism
There is no install spec. The script requires Node and the npm package 'qrcode' (not declared) and will optionally call the system 'convert' binary to produce PNGs. This is operationally important (dependencies must be present) but not a security red flag.
Credentials
No environment variables, credentials, or config paths are requested. The script only uses user-supplied CLI arguments (slug, title, mode, github, out).
Persistence & Privilege
Skill is not always-enabled and does not request persistent system privileges. It writes output files to a local ./images/ directory (expected behavior) and does not modify other skills or system-wide configuration.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install skill-qr-card
  3. After installation, invoke the skill by name or use /skill-qr-card
  4. Provide required inputs per the skill's parameter spec and get structured output
