Manages dependencies with deno install and deno add, supports package.json and node_modules, handles npm and JSR packages, permissions, and configuration across package.json, tsconfig.json, and deno.json, includes workspaces and the built-in toolchain (fmt, lint, test, check, bench, compile), and facilitates publishing.
Install
skills is a generic installer for any repository of Claude agent skills -- it reads denoland/skills’s own structure rather than assuming one, the same way this page reads the skill’s own SKILL.md rather than assuming a format.

Maintenance
Use when writing, running, configuring, reviewing, or debugging code in a Deno project, or when scaffolding a new one. Covers dependency management with deno install and deno add, package.json and node_modules support, npm and JSR packages, permissions, where configuration belongs across package.json, tsconfig.json and deno.json, workspaces, the built-in toolchain (fmt, lint, test, check, bench, compile), and publishing.
