Minimal access
Why this level
- The skills edit project files and run `deno`, and broad permissions such as `-A` give programs access to the whole system.
Install
- Works in
In your terminal, with SkillFoxx CLI
npx skillfoxx add plugins/deno-skillsDetects the agents on your machine, shows the access level and pins the version.

What it does
A set of five skills from Deno Land. `deno` covers dependencies, permissions, `deno.json`, the built-in toolchain and publishing. `migrate-to-deno` moves projects from Node, npm, Yarn, pnpm and Bun, `deno-deploy` guides deployment, `deno-frontend` covers Fresh, Preact and Tailwind CSS, and `deno-sandbox` runs untrusted code safely through `@deno/sandbox`. The skills tell an agent that npm and JSR work together, that `deno fmt`, `deno lint` and `deno test` replace prettier, eslint and jest, and that permissions are best granted narrowly, for example `--allow-net=example.com`, rather than with `-A`.
Who it is for. TypeScript developers writing or migrating Deno projects in Claude Code, Cursor or Copilot.
Good fit when
- A Node project with `package.json` is moved to Deno without a rewrite.
- A new Fresh application is built with Preact and Tailwind CSS.
- A service ships to Deno Deploy and the agent needs details on databases, domains and authentication.
- User code runs in an isolated environment through `@deno/sandbox`.
Not a fit when
- The project stays on Node or Bun with no migration plan.
- Deno is older than 2.9; the examples target a newer release.
- Skills for other frameworks are needed; the set covers Deno and its ecosystem only.
Example request
Move this project from npm to Deno: keep `package.json`, replace prettier and eslint with built-in commands and grant minimal permissions.Limitations
The skills target Deno 2.9 and newer and may diverge from older releases. In Cursor, agent skills need version 2.4, and in VS Code with Copilot the `chat.useAgentSkills` setting must be enabled. The three former skills (`deno-guidance`, `deno-expert`, `deno-project-templates`) merged into `deno` in plugin version 2.0 and need no separate install. The skills change project files and run `deno`, so grant run permissions narrowly. Last commit in the repository: July 2026.
How to disable. In Claude Code run `/plugin uninstall deno-skills@denoland-skills`. For a manual install, delete the skill folders from `~/.claude/skills/`, `~/.cursor/skills/` or `.github/skills/`.
FAQ
How do I install a single skill?
Run `npx skills add denoland/skills --skill deno`. Replace `deno` with another skill name from the set.
How do I install it as a Claude Code plugin?
Run `/plugin marketplace add denoland/skills`, then `/plugin install deno-skills@denoland-skills`.
What happened to the old `deno-guidance` and `deno-expert` skills?
They merged with `deno-project-templates` into the single `deno` skill. If you installed them separately, install `deno` instead.
How do I install the skills manually?
Copy the folders you need from `skills/` to `~/.claude/skills/` for Claude Code or `~/.cursor/skills/` for Cursor.
When do the skills trigger?
When an agent works in a project with `deno.json`, creates a Deno application, adds dependencies or deploys to Deno Deploy.
