Longxia Skill Scanner

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed remote scanner that sends a user-provided public GitHub URL to Longxia and does not execute the target repository.

Install this only if you are comfortable sending the public GitHub URL you provide to Longxia's remote scanning service. Do not use it with private repositories, credential-bearing URLs, internal links, or URLs containing sensitive query parameters.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The script sends the user-supplied GitHub URL to a third-party service at https://longxia.cool/api/scans, which is an external data transmission. Even though this behavior is consistent with the skill’s stated purpose, there is no runtime warning, consent prompt, or inline disclosure in the script itself, so users may unknowingly transmit private repository paths, sensitive URL tokens, or internal metadata if they misuse the tool.

      --silent \
      --show-error \
Confidence
88% confidence
Finding
This curl invocation performs outbound network communication to an external API using user-provided input. In the context of a scanning skill this is expected, but it still creates a real privacy and data-handling risk because repository URLs are exfiltrated to a remote service without additional guardrails, disclosure, or validation beyond basic hostname checking.
