Work on a Deno project
Use the Deno guidance when your coding agent needs to manage dependencies, work with project configuration or use the runtime's built-in development tools.
Overview
This marketplace provides the deno-skills plugin, which brings Deno's agent skills into Claude Code for work on JavaScript and TypeScript projects. The guidance covers dependency management, permissions, project configuration, the built-in development tools and publishing. For existing projects, the migration guidance separates adopting Deno into choices about package management, running code, permissions and the development toolchain.
The plugin also provides guidance for Deno Deploy, frontend development and isolated code execution with Deno Sandbox. Claude can load each skill when relevant to your request; you can also invoke a skill explicitly from the slash menu.
Use Cases
Assess a move to Deno
For a project using Node.js, npm, Yarn, pnpm or Bun, use the migration guidance to assess dependencies, scripts and development tooling before choosing changes. Package management, running the project, tightening permissions and adopting the built-in toolchain can be considered separately.
Components
The guidance targets Deno 2.9 and later.
