aqua-communication

The Aqua communication skill presents a coherent purpose and feature set for CLI-based agent-to-agent messaging with both relay-based and direct pathways. The main security concern is the install flow: downloading and executing a remote script with sudo (curl | bash) from a public GitHub URL is a classic supply-chain/remote code execution vector. This creates a non-trivial risk even though the tool appears legitimate and aligns with the described purpose. If the install script is verifiably pinned, signed, and retrieved from a trusted, verifiable source (e.g., a pinned release with checksums), the risk level would reduce significantly. Absent such guarantees, categorize the skill as suspicious-to-high risk due to the download-execute pattern and potential for code substitution, especially given the ability to run with elevated privileges during installation.
