    "description": "A plugin and extension system architecture for building extensible\nTypeScript applications. JSON Schema defines plugin manifests and\nconfiguration contracts. Zod performs runtime validation of plugin\ninputs and outputs. esbuild bundles plugins into self-contained\nmodules with minimal dependencies. Vitest tests both the plugin\nhost runtime and individual plugin implementations. npm serves as\nthe distribution registry. Designed for teams building extensible\ndeveloper tools, CMS platforms, and automation frameworks where\nthird-party code must execute safely within a host process. The\ntradeoff is the security boundary — plugins running in-process\nshare the host's permissions, requiring careful sandboxing or\ncapability-based access control to prevent malicious extensions.\n",
