The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructions in SKILL.md direct the user to install the ble-opaque-binary-pp-cli tool using npx -y @mvanhorn/printing-press-library install ble-opaque-binary --cli-only. This command fetches and executes the installer from the author's official NPM package.
[COMMAND_EXECUTION]: The skill operates by executing the ble-opaque-binary-pp-cli binary to perform discovery (scan), status checks, and capability reporting.
[INDIRECT_PROMPT_INJECTION]: The skill processes telemetry data from external BLE devices, which represents a potential attack surface where a device could provide malicious input to the agent context.
Ingestion points: BLE characteristic data read via the status command.
Boundary markers: No specific boundary markers or 'ignore' instructions are present in the command output templates.
Capability inventory: The skill has the ability to execute the CLI tool and perform BLE network communication via the tinygo.org/x/bluetooth library.
Sanitization: The tool outputs telemetry derived from device GATT characteristics; no explicit sanitization or validation of the device-provided strings is performed before returning them to the agent.
