The Agent Skills Directory

[SAFE]: The skill provides standard architectural patterns for performance optimization, such as code splitting, image optimization, and caching.
[DATA_EXFILTRATION]: The skill demonstrates capturing Real User Monitoring (RUM) data using the web-vitals library and sending it via navigator.sendBeacon to an internal /api/vitals endpoint. This is a standard and safe telemetry practice for monitoring production performance.
[OBFUSCATION]: A Base64 string is present in the HeroSection component as a blurDataURL placeholder. This is a standard technique for low-quality image placeholders during lazy loading and does not contain hidden instructions or malicious payloads.
[COMMAND_EXECUTION]: The skill includes instructions for running performance analysis tools like k6, artillery, and source-map-explorer. These are standard developer tools used appropriately for performance validation and load testing.
