The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes local scripts (upload.mjs and download.mjs) executed via the Bun runtime to manage file operations and network requests.
[DATA_EXFILTRATION]: Performs file uploads to user-defined Xdrop servers. While this involves sending local data to a remote endpoint, it is the primary intended function of the skill and requires user-provided configuration (server URL).
[EXTERNAL_DOWNLOADS]: Fetches encrypted data and manifests from remote servers during the download and decryption process.
[SAFE]: Includes a robust sanitizePath function in scripts/download.mjs that prevents directory traversal attacks by filtering out '..' segments and stripping dangerous characters from server-provided filenames.
[SAFE]: Employs standard cryptographic practices using node:crypto and crypto.subtle for AES-GCM encryption and HKDF key derivation, ensuring file content remains encrypted while stored on the intermediary server.
