Daytona Electron Den Agent Skill

Daytona Electron Against Den

Use this skill for full-stack cloud behavior: one Daytona sandbox runs Den, and a

separate Daytona sandbox runs the real Electron app pointed at that Den server.

Start The Server Sandbox

Use the server skill first:

bash .devcontainer/test-server-on-daytona.sh <branch-or-commit>

Record the printed values:

• SERVER_SANDBOX
• DEN_WEB_URL
• DEN_API_URL
• DEN_WORKER_PROXY_URL

Validate server health:

curl -sf "$DEN_WEB_URL/api/den/health"
curl -sf "$DEN_API_URL/health"

Start Electron Against Den

bash .devcontainer/test-on-daytona.sh <branch-or-commit> \
  --den-base-url "$DEN_WEB_URL" \
  --den-api-base-url "$DEN_API_URL" \
  --artifacts-volume

Add --require-signin when the expected behavior must be signed-out until cloud

auth completes. Add --record-video --recording-name <name> when PR evidence is

needed.

Validate Bootstrap

Before testing cloud behavior, prove Electron is using the Daytona Den server:

JSON.stringify({ hash: location.hash, text: document.body.innerText.slice(0, 1000) })

Then inspect the desktop bootstrap file:

daytona exec "$SANDBOX" -- 'cat /workspace/.ipollowork-daytona/desktop-bootstrap.json'

Expected: baseUrl is DEN_WEB_URL and apiBaseUrl is DEN_API_URL, not

production.

Desktop Handoff Pattern

For seeded/demo auth, create the handoff URL from the Den API, then paste it into

Electron's Cloud Account sign-in code field. Do not rely on browser navigation

alone as proof that desktop auth completed.

Validate all of these:

• Electron Cloud Account shows signed-in user/org state.
• Den API logs show handoff exchange or /v1/me/orgs.
• Electron UI can refresh cloud providers/workers/marketplace without production URLs.

Marketplace, Policy, Provider Sync

For each cloud feature, use the daytona-flow-validator loop:

• Assert server seed or API state.
• Act in Electron UI.
• Assert Electron visible state.
• Assert Den logs/API state if relevant.
• Capture screenshot or recording evidence.

Minimum assertions:

• Marketplace: package appears, install/remove changes local extension state.
• Org policy: restriction appears in Electron and persists after reload.
• Provider sync: Den-managed provider appears as imported/credential-ready, model can be selected, and task metadata uses the Den provider id.
• Worker proxy: worker/proxy failures affect only worker UI and recover after proxy restart.

Evidence

Report both server and Electron proof:

• Den Web/API health checks.
• Relevant /tmp/den-*.log snippets.
• Electron CDP assertions and screenshots.
• Recording URL if requested.
