[COMMAND_EXECUTION]: The skill utilizes bundled ZSH scripts to interface with the macOS /usr/bin/security command-line tool. This is the standard system utility for managing credentials on macOS and is used here to perform operations such as checking, setting, and deleting keychain items.
[DATA_EXFILTRATION]: By design, the skill accesses sensitive credential data within the macOS Keychain. However, the implementation includes strong security controls, such as mandatory user confirmation prompts before any plaintext secret is retrieved or displayed. The skill does not perform any network operations, ensuring that credential data remains local to the system.
