deno SKILL.md skillA

deno from openhands/extensions is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add openhands/extensions/deno@git:20260214.cb4039b

Pins git:20260214.cb4039b in mdr.lock. Pin the fingerprint instead.

If the project uses deno, use this skill. Use this skill to initialize and work with Deno projects, add/remove dependencies (JSR and npm), run tasks and scripts with appropriate permissions, and use built-in tooling (fmt/lint/test).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Deno

Use Deno as the default runtime/tooling when the repo contains `deno.json`/`deno.jsonc`, uses `deno.lock`, or scripts/documentation reference `deno task`, `deno run`, `deno test`, etc.

## Quick decision rules

- Prefer `deno task <name>` if the repo defines tasks.
- Use `deno add` / `deno remove` to manage dependencies (writes to config).
- Be explicit about permissions for `deno run` / `deno test`.

## Common operations

### Initialize a new project

```bash
deno init
```

### Add dependencies (JSR and npm)

```bash
# JSR (recommended for Deno-first packages)
deno add jsr:@std/path

# npm packages are supported too
deno add npm:react

# multiple at once
deno add jsr:@std/assert npm:chalk
```

### Remove dependencies

```bash
deno remove jsr:@std/path
```

### Run a script

```bash
# Minimal permissions: only what the program needs
# Examples:
#   --allow-net=api.example.com
#   --allow-read=./data
#   --allow-env=FOO,BAR

deno run --allow-net --allow-read main.ts
```

### Run tasks

```bash
# list tasks
deno task

# run a task defined in deno.json/deno.jsonc
deno task dev
```

### Formatting, linting, testing

```bash
deno fmt
deno lint
deno test

How to install

The exact contents, by fingerprint
mdr add openhands/extensions/deno@sha256:6704eb29264daea9

The line at the top of this page pins the label git:20260214.cb4039b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
