Least-privilege permissions

• Restrict file access: Only allow the AI agent to read input files it needs and write QR code outputs to a dedicated folder; prevent access to other system files or sensitive data directories.
• Limit user scope: Grant this skill to only the teams or users who genuinely need QR code generation; don't enable it for all users by default.
• Control output sharing: Implement access restrictions on generated QR code files so they aren't automatically viewable by unauthorized people.

Network isolation

• No external data fetching: Ensure the skill cannot download or fetch content from the internet unless explicitly needed; this reduces the risk of injecting malicious code.
• Firewall QR generation: If possible, run this skill on an isolated or sandboxed system separate from critical business systems to contain any potential damage.
• Audit API calls: Monitor what external services (if any) the skill communicates with; document and approve all outbound connections.

Monitoring

• Log all QR generation requests: Record who creates QR codes, what data is encoded, and when—this helps detect misuse or suspicious patterns.
• Track input sizes: Watch for unusually large input strings being submitted, which could indicate an attempt to crash the system or exhaust memory.
• Alert on repeated failures: Set up alerts if QR generation fails repeatedly, as this could signal an attack or malfunction.

Red flags to watch for

• Sensitive data in QR codes: Stop and review if QR codes ever contain passwords, API keys, social security numbers, or other secrets—this defeats the purpose of a QR code's security.
• Rapid generation spikes: Sudden unusual increases in QR code creation requests may indicate automated abuse or malicious activity.
• Abandoned maintenance: Regularly check if the skill's underlying library receives security updates; if the maintainer stops responding to security issues, consider finding an alternative.
