At a glance

Test any GUI app or change on a Daytona Windows remote desktop sandbox.

  • Launch a GUI program
  • SKILL.md covers Overview, When to Use, Usage and Typical flow, plus 3 more sections
  • Runs JavaScript scripts from its folder; calls node and npm; needs DAYTONA_API_KEY
  • Sync a local project

What it does

Remote Desktop Testing Windows is an agent skill from letta-ai/skills. Test any GUI app or change on a Daytona Windows remote desktop sandbox. Use to launch a GUI program, sync a local project, take a screenshot, record a video, or share a clickable live-desktop link with a teammate. Generic — the only dependency is Daytona. For Linux, use remote-desktop-testing-linux.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts.

It works with Linux and Letta. The repository describes itself as: A shared repository for skills. Intended to be used with Letta Code, Claude Code, Codex CLI, and other agents that support skills.

When your agent uses it

  • Launch a GUI program
  • Sync a local project
  • Take a screenshot
  • Share a clickable live-desktop link with a teammate

Example prompts

  • “/remote-desktop-testing-windows”

Requirements

  • Node.js
  • A credential in DAYTONA_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 6785511. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • DAYTONA_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Remote Desktop Testing Windows loads about 1.5k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 607 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:31
    environment or a dotenv file — `./.env` by default, override with `--env-path <file>`.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 607 words (~1,530 tokens).

“Generic Daytona Windows sandbox driver. It creates (or reuses) a Windows sandbox whose desktop is streamed over noVNC, and provides the primitives for visual testing of any GUI app: sync code, run PowerShell, launch GUI programs in the interactive desktop…”
