tc-protohub

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed ProtoHub publishing helper that reads user-selected prototype files and sends them to a configured ProtoHub API, with no hidden install-time or persistent behavior found.

Install only if you intend to let the agent publish or update ProtoHub prototypes. Use a scoped ProtoHub API key, verify PROTOHUB_URL or --url before running, publish from a clean build/output folder, and confirm the target ID or matched name before updating an existing prototype.

MCP Least Privilege
Confidence
94% confidence
Finding
The skill clearly instructs the agent to read environment variables, access local files/directories or ZIPs, and make authenticated network requests, yet it declares no explicit permissions. This creates a trust and review gap: an operator may invoke the skill without realizing it can exfiltrate local prototype contents or secrets to a remote ProtoHub endpoint, especially since the URL can be overridden from configuration.

Vague Triggers

Medium
Confidence
89% confidence
Finding
The eval prompts describe desired actions but do not define tight trigger boundaries for when this skill should or should not be invoked. In an agent environment, broad invocation semantics can cause the skill to activate on loosely related user requests, leading to unintended file packaging, uploads, updates, or metadata disclosure against ProtoHub resources.
