Anthropic Just Shipped Claude 2.0 (Master it in 17 minutes)

Summary

Jay presents a guide to major changes in the Claude desktop app, emphasizing Claude Code as the place where many of Anthropic’s newest features are appearing. He stresses that “Code” does not require programming: users can direct it in plain English.

Session rail and context visibility

• The session rail shows a chat’s working folder, whether it runs locally or in the cloud, connected apps, and files it has created.
• Remote control lets users continue a session from a phone. Settings can enable it for new sessions and keep the computer awake while Claude works.
• A context card shows what is using the chat’s context window, including messages, memory, skills, and connectors. The video says newer Claude models have a 1-million-token context window and notes that preloaded skills and connectors count toward usage.

Sections and nested sessions

Chats can be organized into named sections, similar to folders.

A session can launch separate, interactive chats—called “nested sessions”—for parallel tasks. Unlike simpler sub-agents, nested sessions appear in the sidebar, can be inspected, and can be continued directly.

Master sessions

One chat can act as a coordinator, checking other sessions for decisions awaiting the user, summarizing their status, and starting or managing new sessions.

By default, it can see the 20 most recently active sessions, though Jay says users can ask it to look further back.

Claude Code Projects

Projects run in Anthropic’s cloud, so work can continue after a device is closed. They offer shared project memory and an overview of completed, active, and waiting tasks.

Nested sessions run locally and have easier access to local files, skills, and tools. Projects require those resources to be added, and uploaded business files are stored on Anthropic’s servers.

The video describes Projects as a beta rolling out to Pro and Max users, while nested sessions are available on any plan.

Side chats and split view

Side chats—opened from the menu or with /BTW—can read the main session, letting users ask about progress without interrupting the main task. Unlike the previous temporary version, these chats are saved.

Split view displays multiple sessions together. Jay suggests starting with two panes; too many simultaneous chats can become difficult to manage.

Artifacts

Claude’s collaborative artifacts include Docs, Slides, visual Design projects, data-connected Dashboards, and Claude Motion animated videos.

• Artifacts can be shared or published as links.
• Slides can be downloaded as PowerPoint files or presented in Claude.
• Dashboards can show updated data from connected apps.
• Claude Motion generates animations with code rather than a video model, which Jay says makes them cheaper to produce and easier to modify.

Feature availability varies by plan. Jay also says the standalone Claude Design site is scheduled to close on December 14.

AI-powered artifacts

A setting enables Claude to be embedded in artifacts. For example, a shared dashboard can include a chat box or search bar so teammates can ask questions about its data without using Claude Code themselves.

Slash commands

• /output-style changes Claude’s response style, such as making it shorter or less technical.
• /doctor checks configuration and suggests fixes.
• /skill-doctor reports on skills’ memory use and frequency, helping users identify skills to disable.
• /advisor can call on a stronger model for important decisions while using a less costly model for routine work.
• /insights reports on usage.
• /recap summarizes a session’s status.
• /rewind returns to an earlier point in a chat.

Mods

Mods are add-ons that change Claude Code’s appearance or behavior. They can be created by describing the desired change to Claude.

Jay highlights:

• Ribbon, which displays usage and prompt-cache status. Jay says it is free and open source.
• Savvy Progress, which shows task progress and the activity of helpers or sub-agents.

Keyboard shortcuts

• Ctrl + Alt + Space opens Claude from elsewhere on the computer.
• Pressing Esc twice triggers rewind.
• Ctrl + D enables voice transcription.
• Ctrl + / or Command + / displays the shortcut list.

The video also mentions a free PDF guide containing its prompts, resources, and shortcuts, plus separate tutorials on Claude Motion and Claude mods.

Main speaker and source

• Jay E (RoboNuggets) is the presenter and primary source of the explanations and recommendations.
• Anthropic is referenced as the source of the app features and published tips. Jay also cites an unnamed lead engineer’s description of the overhaul as “Claude 2.0.”
