When Your AI Coding Plugin Starts Picking Your Dependencies: Marketplace Skills And Dependency Hijack In Claude Code
SentinelOne, Monday, January 5th, 2026
AI coding assistants are no longer just autocompleting lines of code, they are quietly making decisions for you. Tools like Claude Code are able to read projects, plan multi-step changes, install dependencies, and modify files with minimal human oversight.
To make this possible, these assistants rely on plugin marketplaces, where third-party developers can enable 'skills' that teach the agent how to manage infrastructure, testing, and dependencies. Though powerful, the model requires a high degree of trust, thus bringing with it a new set of risks.
At a first glance, third-party marketplace plugins are harmless productivity boosters. Connect a marketplace and enable a plugin so your coding assistant becomes smarter about your stack.
