FAQPage Schema
How do I scan external skills for prompt injection before installation?

Pre-installation scanning detects prompt injection and command injection by validating target skill files against predefined checks. Running this scanner outputs a structured scan result with recommendations, reducing the risk of integrating unsafe external capabilities.

What is pre-install skill validation for malicious patterns?

Pre-install skill validation is a safety process that checks third-party plugins for command injection and data exfiltration patterns before integration. It enforces safety by applying predefined checks to ensure safe integration into development pipelines.

Can I use command injection detection in my CI/CD pipeline?

Yes, you can use command injection detection in CI/CD pipelines. The scanner applies pre-installation safety checks across environments, validating any plugin or skill integration where third-party capabilities are added during automated development workflows.

How do I check a plugin for data exfiltration patterns?

You check a plugin for data exfiltration patterns by running a scanner on the target skill file before installation. This detects common command-and-data exfiltration patterns and outputs a structured scan result with actionable safety recommendations.

Does pre-install plugin validation work for local development setups?

Yes, pre-install plugin validation works for local development setups. The scanner applies predefined safety checks across any environment where third-party capabilities are added, including both local configurations and CI/CD development pipelines.
