How Good is Opus 4.7 Really? (New Claude Code Desktop Test)

Description

🚀 Join a growing community of builders learning agentic coding: https://www.skool.com/agentic-labs In this video, we take the new Claude Code Desktop App for a spin with Anthropic's brand new flagship coding model, Opus 4.7. Instead of looking at benchmarks, we push Opus 4.7 to the limit with a one-shot prompt to build a full infinite canvas app (an Excalidraw / Eraser alternative) from scratch. You'll see the complete developer experience of the new Claude Code Desktop app, including parallel agent sessions, the planning pane, bypass permissions mode, the embedded browser preview, file diff reviews, and how Opus 4.7 handles complex agentic coding tasks with the new extra-high reasoning effort. ⏰ TIMESTAMPS: 00:00 Opus 4.7 and Claude Code Desktop launch 00:26 New Claude Code Desktop App UI 00:41 Workspaces and projects sidebar 00:54 Starting a new session 01:04 Local folder vs GitHub repo 01:22 Permission modes explained 01:48 One shot prompt challenge 02:44 Infinite canvas app prompt 04:43 Opus 4.7 extra high reasoning 05:26 Agent clarifying questions 06:44 Tasks and agent progress view 07:39 Reviewing the architecture plan 08:19 Bypass permissions mode 08:37 Scaffolding the Next.js app 09:10 Parallel agents across workspaces 10:24 File diff code review 11:17 Slash commands and context window 11:52 Embedded browser preview pane 12:23 Agent end to end testing 13:17 Testing shapes and connectors 14:04 PNG export functionality 14:17 Adding icons and customization 14:45 Keyboard shortcuts demo 15:30 Final verdict on Opus 4.7 Business & sponsorship enquiries: leon.vanzyl@gmail.com #claudecode #agenticcoding #vibecoding
