Your team is moving from the terminal to the VS Code extension, and someone asks whether Claude will be able to do less. What is the answer?

The principle — choose a surface for how you like to work, not for what it unlocks.

Why the key is correct — Anthropic defines a surface as any place you access Claude Code — the CLI, VS Code, JetBrains, Desktop or claude.ai — and states that all surfaces share the same engine. The agentic loop, the tools and the way permissions gate them all come from that engine. So the honest answer to the team is that the interface changes and the capability does not, which turns the decision into a question of preference rather than of trade-off.

Why the others are wrong — treating the terminal as the full product mistakes seniority for scope. Expecting the surfaces to drift apart describes independently built products, which is precisely what a shared engine rules out. And an extension is not a remote execution environment; where you type and where code runs are different questions, and conflating them makes ordinary local work look like a hosted service.

Remember this — the interface changes, the engine does not.
