What it is: Visual Studio Code is the host, not the agent: one Session Target control switches a session between five harnesses — Local, GitHub Copilot, Anthropic Claude, OpenAI Codex and Cloud — so the editor stays fixed while the agent behind it changes. [code.visualstudio.com/docs/agents]
Choose Visual Studio Code when: Run Anthropic's agent without installing a second product: the Claude harness is enabled by default and bills either through a GitHub Copilot subscription or through your own Anthropic key. [code.visualstudio.com/docs/agents]
Where it hurts: The app you download is not the MIT repository: Microsoft ships Visual Studio Code as a licensed distribution of the open-source Code - OSS tree, and says the product is built on open source rather than being open source. [code.visualstudio.com/docs/supporting]
Price: The editor is free but the agents are not: reaching the Claude Code and Codex harnesses through a Copilot subscription starts at Copilot Pro, $10 per user a month. [github.com/features/copilot]
