Risk Level: SAFE
Full Analysis
- [SAFE]: The skill focuses on performance optimization using standard web platform features like
fetchpriority,Speculation Rules API, andPerformanceObserver. - [DATA_EXFILTRATION]: The code examples include patterns for Real User Monitoring (RUM) using
navigator.sendBeacon. These examples use relative paths (e.g., "/rum"), which is standard practice for same-origin telemetry and does not pose an exfiltration risk. - [PROMPT_INJECTION]: No attempts to override agent behavior, bypass safety guidelines, or perform indirect injection were detected. The skill specifically includes defensive patterns to exclude destructive URLs (e.g., "/logout") when using speculation rules, which is a security best practice.
- [REMOTE_CODE_EXECUTION]: No remote script downloads or dynamic code execution patterns were found.
- [COMMAND_EXECUTION]: No shell command execution or privilege escalation patterns were found.
