The Agent Skills Directory

[COMMAND_EXECUTION]: The skill requires the use of elevated privileges to install external dependencies.
Evidence: sudo apt-get install is used to install nmap, netcat, hydra, and smtp-user-enum in the prerequisites section.
[COMMAND_EXECUTION]: The workflow involves executing aggressive security tools designed for reconnaissance and exploitation.
Evidence: Use of hydra and medusa for credential brute-forcing, nmap scripts for vulnerability detection, and smtp-user-enum for account discovery.
[EXTERNAL_DOWNLOADS]: The skill triggers the download of software packages from remote repositories.
Evidence: Software installation commands (apt-get install) fetch external binary packages at runtime.
[PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection by processing unsanitized output from remote SMTP servers.
Ingestion points: Banner grabbing (nc TARGET_IP 25) and command enumeration (EHLO responses) in Phases 3 and 4 ingest data directly from target servers into the agent's context.
Boundary markers: None present; external server responses are not wrapped in protective delimiters.
Capability inventory: The skill has extensive command execution capabilities (subprocess calls for nmap, hydra, openssl, etc.).
Sanitization: No validation or escaping is performed on the server-provided strings before processing.
