Breakdown Connectivity

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed macOS connectivity diagnostic skill with optional Breakdown installation and MCP setup, and no evidence of hidden collection, exfiltration, or destructive behavior.

Install this only if you want Breakdown integrated with your agent for macOS connectivity diagnostics. Review and approve any installer launch or MCP configuration command, because those steps change local application and agent configuration.

MCP Least Privilege
Confidence
88% confidence
Finding
The skill instructs the agent to execute local shell commands such as `./scripts/setup-breakdown.sh install` and related setup operations, but no explicit permissions or trust boundary are declared. This creates a real risk because the skill can trigger installation, app launching, and configuration changes on the host, and users or orchestrators may not realize the skill requires command execution and system modification capabilities.
