VS Code

Source-first development in the editor you already use.

Edit declarative models, navigate the application structure and see diagnostics as you type, on the same tooling contracts as the cell CLI.

What the extension does

Part of Community, not a demo.

The extension relies on the same native tooling operations as the CLI. Business rules aren’t re-implemented in the editor, so what VS Code shows you is what the runtime resolves.

Edit

XML and YAML models

Declarative parsing with source ranges, diagnostics and completion.

Navigate

Source-aware structure

Explore the project and the document structure, and jump to the physical source of any element.

Automate

Same contracts as the CLI

Use VS Code for interactive work and cell for scripts and CI, on the same application.

Maturity per capability

Some advanced capabilities are still stabilising. Each release lists which editor features are available and which are in progress. Release notes
