Use this skill for Daytona infrastructure, not test placement.
Setup
Install the Daytona CLI with brew install daytonaio/cli/daytona, then authenticate:
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.
For a PR preview that should open inside Codex and support named scenarios, use preview-my-work. It composes the same maintained world and Daytona primitives with scoped ownership and teardown.
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:
daytona preview-url <sandbox> -p 9825
daytona preview-url <sandbox> -p 6080
Secrets
bash .devcontainer/setup-daytona-secrets-volume.sh <local-env> <name>.env
Electron sandboxes mount the reusable secrets volume at /daytona-secrets.
Snapshot refresh
bash .devcontainer/create-daytona-openwork-snapshot.sh
bash .devcontainer/create-daytona-openwork-server-snapshot.sh
Teardown
daytona delete <sandbox>
