description: Daytona CLI setup, sandbox debugging, keep a sandbox alive, secrets volume, snapshot refresh. Use when Daytona itself is the problem, not for running tests (see run-tests).

# Daytona

Use this skill for Daytona infrastructure, not test placement.

## Setup

Install the Daytona CLI with `brew install daytonaio/cli/daytona`, then authenticate:

```bash

daytona login

```

To run tests, just use `pnpm evals:e2e <slug>` — it picks Daytona automatically

when the CLI is authenticated. `--local` forces local; `--daytona` requires

Daytona and fails when it is unavailable.

## Long-lived manual Electron sandbox

Run `bash .devcontainer/test-on-daytona.sh <ref>`. The maintained helper uses

the reusable desktop snapshot, starts XFCE/noVNC, Vite, and Electron, and prints

the sandbox and preview URLs. Keep that sandbox for exploration or debugging

instead of reproducing its provisioning commands.

## Long-lived manual server sandbox

Run `bash .devcontainer/test-server-on-daytona.sh <ref>`. It starts the separate

MySQL, Den API, and Den Web sandbox and prints public URLs for a desktop sandbox

to consume. Use this helper rather than assembling the server manually.

## Debugging

Inspect `/tmp/start-vnc.log`, `/tmp/vite.log`, `/tmp/electron.log`, and

`/tmp/den-api.log` in the relevant sandbox. Electron CDP is port `9825`; get CDP

and noVNC URLs with:

```bash

daytona preview-url <sandbox> -p 9825

daytona preview-url <sandbox> -p 6080

```

## Secrets

```bash

bash .devcontainer/setup-daytona-secrets-volume.sh <local-env> <name>.env

```

Electron sandboxes mount the reusable secrets volume at `/daytona-secrets`.

## Snapshot refresh

```bash

bash .devcontainer/create-daytona-openwork-snapshot.sh

bash .devcontainer/create-daytona-openwork-server-snapshot.sh

```

## Teardown

```bash

daytona delete <sandbox>

```
