The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to download the ngrok agent binary from the vendor's official distribution domain at bin.equinox.io.
[COMMAND_EXECUTION]: The instructions involve executing shell commands to download, extract, and start the ngrok agent binary (ngrok start).
[PRIVILEGE_ESCALATION]: The skill describes installing the ngrok agent as a native OS service, which typically requires root or administrator privileges on the host system.
[PERSISTENCE]: The skill facilitates maintaining persistent access to the sandbox environments by configuring the ngrok agent as a native system service (e.g., using systemd on Linux) to ensure it restarts automatically.
[INDIRECT_PROMPT_INJECTION]: The skill ingests a uuid from the control plane's object model to derive resource names and internal hostnames.
Ingestion points: A UUID string is provided by the control plane environment to identify sandboxes.
Boundary markers: None explicitly mentioned for the UUID string, though it is used within structured identifiers.
Capability inventory: The skill uses the ngrok API to provision service users, credentials, and endpoints, and executes shell commands for agent management.
Sanitization: The skill assumes the identifier is derived from a trusted internal object model, though no specific sanitization of the UUID string is described before interpolation into URLs and names.
