VS Code, Cursor, and Antigravity share the same technical base – which is why the platform integration works identically in all three editors.
Opening a project
Open your project from the setup app with one click in your preferred editor – or open the project folder (~/Documents/application-platform/<organization>/<project>) manually. Important: open the parent project folder, not a single repository – this way you see all repositories and the shared configuration applies.
The Application Platform extension
The extension doppelt-digital.application-platform is installed automatically by the setup app in VS Code, Cursor, and Antigravity, and is also listed as a recommendation in the workspace configuration. It provides:
- A welcome page with all repositories of your project: description, tech stack, recommended files, and links (GitLab, Sentry, docs).
- A start button per repository: opens a terminal and runs
ap run-localwith the right parameters. - Quick links to the platform web app and AI tools.
- Open GitOps secrets decrypted – view encrypted configuration files directly in the editor.
Generated configuration
The local-configuration repository (available via symlinks in the project folder) contains:
| Folder/file | Effect |
|---|---|
.vscode/ |
Extension recommendations for VS Code |
.cursor/rules/ |
Cursor rules, including the platform guidelines for AI agents |
.antigravity/ |
Agent rules for Antigravity |
AGENTS.md |
Central instructions for all AI tools |
The AI in Cursor and Antigravity automatically follows the platform conventions (e.g. use ap run-local, don’t change generated files, never commit secrets). Add your own rules as described in Telling the AI how to work.
