SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the critical need for trust and security within a plugin ecosystem by providing a robust framework for verifying, auditing, and scoring third-party plugins.

Core Features & Use Cases

  • Plugin Verification: Ensures the integrity and authenticity of plugin packages through signature verification.
  • Permission Sandboxing: Enforces strict runtime boundaries on plugin resource access (filesystem, network, execution).
  • Trust Scoring: Assigns a composite score based on multiple factors (signature, reputation, code analysis, community, freshness) to guide user decisions.
  • Security Auditing: Statically analyzes plugin code for dangerous patterns and potential vulnerabilities.
  • Use Case: Before installing a new plugin from a marketplace, an administrator can use this Skill to get a comprehensive security report and trust score, ensuring the plugin is safe to integrate into their system.

Quick Start

Use the supply-chain-security skill to get a trust score for the plugin named 'data-enricher'.

Frequently Asked Questions about supply-chain-security

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check a plugin for security vulnerabilities before installing it?▼

To check a plugin for security vulnerabilities, you can perform a static security audit that analyzes the code for dangerous patterns and generates a comprehensive report on potential risks before installation.

Can I restrict plugin resource access to the filesystem and network?▼

Yes, you can restrict plugin resource access by applying permission sandboxing, which enforces strict runtime boundaries on filesystem, network, and execution permissions for third-party plugins.

How does trust scoring work for marketplace plugins?▼

Trust scoring works by assigning a composite score based on multiple factors, including signature verification, reputation, code analysis, community feedback, and freshness, to guide installation decisions.

What is the best way to verify the authenticity of a third-party plugin?▼

The best way to verify the authenticity of a third-party plugin is through signature verification, which ensures the integrity and authenticity of the plugin package before it is integrated into your system.

Do I need a security audit if my plugins are sandboxed?▼

Yes, you still need a security audit because permission sandboxing enforces runtime boundaries, but static code analysis is required to proactively identify dangerous patterns and underlying vulnerabilities within the plugin code.
