# Agent observability

> Visibility into agent behavior through screenshots and reasoning traces.

Deck gives you visibility into what your agents are doing. Task runs produce screenshots and reasoning traces that you can review in the [Console](https://console.deck.co). 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](mailto: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.

## 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.
