# Playground and debugging

> Test deployments and inspect what the agent received for each turn

The agent playground is the fastest way to test a cloud deployment without
building a client. Open a project, choose an environment and agent, then create
a session.

## Select the correct target

The project header selects `development` or `production`. Projects with
multiple agents have a separate agent selector in the playground. A session
keeps the deployment selected when it starts.

Create a new session after changing the target when you want an isolated test.
Resume an existing session when you want to verify multi-turn behavior.

## Use the debug inspector

The inspector shows the information needed to explain a turn:

* deployment and session identifiers
* rendered agent instructions
* selected model
* tools and MCP capabilities available to that render
* tool activity and errors

OpenComputer's private platform instructions and credentials are intentionally
not shown. The inspector describes your deployed agent configuration, not the
internal execution implementation.

## Follow runtime logs

Use the CLI when a failure needs more detail:

```bash theme={null}
npx --package @opencomputer/cli opencomputer logs --follow
npx --package @opencomputer/cli opencomputer logs --session <session-id>
```

See [Logs](/agents/logs) for filters and JSON output.
