deno skillA
deno is agent-read markdown (skill) from openhands/extensions: 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)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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 …

mdr add openhands/extensions/deno@git:20260214.cb4039bmdr add openhands/extensions/deno@sha256:6704eb29264daea9Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
