Human guide: work with your agent → Connect Deepline to a Cowork session and verify the workspace before a data request. Your first win is a working, authorized CLI in the session’s folder.

​
Before you start

Use a Cowork account and a project folder that the session can access. Keep the folder consistent across setup and later CLI calls. Allow the network access required by your organization’s policy. Anthropic documents plugin installation and Cowork access controls. Client screens and organization controls can vary.

​
1. Add the Deepline plugin

Open Cowork’s plugin customization flow. Add the Deepline marketplace:
Install deepline. Open a session with the intended working folder. Let an in-progress installation finish before starting another setup.

​
2. Authorize the workspace

Ask Cowork to follow the canonical installation instructions:
Complete any browser authorization for the intended workspace. Then ask Cowork to run:
The CLI starts, and authorization identifies the intended workspace. A plugin appearing in the library is not sufficient proof of CLI authorization.

​
3. Try a bounded request after setup

The following starter can perform provider-backed work and incur usage. Review its plan and unresolved results before requesting more rows.
If the session cannot reach Deepline, inspect the effective network policy. Ask the organization owner for required access when controls are locked. Do not assume a local browser connection proves the session can reach it. For repeated authorization, check the working folder and folder binding. For CLI failures, use deepline doctor --json. Ask Cowork to explain the failed check before repeating setup.
