Every dependency you add is a supply chain attack waiting to happen

Third-party dependencies represent a significant supply chain security risk. Recent incidents like the XZ backdoor, the Trivy compromise, and LiteLLM being affected illustrate how both runtime and dev dependencies can be weaponized. The real danger isn't just adding dependencies but automatically updating them with tools like Dependabot, which can introduce compromised versions with little review. The recommendation is to turn off automatic dependency updates, be selective about adding new dependencies, and prefer copying small amounts of code over introducing new libraries.
