The Agent Skills Directory

[COMMAND_EXECUTION]: The skill instructs the agent to use a specialized CLI tool called mac-backup for all file operations. The instructions explicitly prohibit the use of raw shell commands like rsync, scp, or sshfs, directing the agent to use the vendor-provided implementation for mirroring, archiving, and restoring files.
[INDIRECT_PROMPT_INJECTION]: The skill processes external job configuration files which could potentially contain malicious instructions.
Ingestion points: The skill reads job definitions from JSON files via the mac-backup plan <job> command.
Boundary markers: None explicitly defined, though the skill requires the agent to verify the plan's metadata (byte counts, volume IDs) against the user's original request.
Capability inventory: The skill has the capability to mirror, restore, and delete files (archive) through the CLI tool.
Sanitization: The instructions require a mandatory plan step to review execution details before proceeding with transfers.
