Deck gives you visibility into what your agents are doing. Task runs produce screenshots and reasoning traces that you can review in the Console. Review what your agent saw, the decisions it made, and how it completed the task. Deck automatically redacts sensitive information from screenshots and reasoning traces, including personal data, passwords, and other credentials. Detection is strong but not perfect, so some content may occasionally pass through. If you spot something that should have been redacted, email help@deck.co and we’ll take a look.

​
Screenshots

Deck captures screenshots automatically during execution, roughly once every 5 seconds. Screenshots are retained for 15 days. Screenshots show what your agent sees at each moment, giving you a visual timeline of the run. Screenshots are available in the Console on any task run detail view, and through the API: 
GET /v2/task-runs/{run_id}/screenshots
The response is paginated, oldest first. Each item carries a pre-signed url for the image, the agent’s reasoning at the time of capture, and the created_at timestamp.

​
Agent reasoning

Each screenshot includes your agent’s reasoning trace: what it observed on the page, what options it considered, and why it chose a specific action. Reasoning traces are attached to screenshots in the Console.
