The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes standard project build and preview commands (e.g., npm run build, npm start) to audit production-ready versions of web applications. These operations are limited to the local environment and the project's own scripts.
[EXTERNAL_DOWNLOADS]: Utilizes npx to execute well-known and official utilities including lighthouse and serve from the standard npm registry. These are established industry tools and are treated as safe within this context.
[DATA_EXFILTRATION]: Includes curl commands strictly for health-checking the local server availability (localhost). No access to sensitive files or external network exfiltration patterns were detected.
