VS Code, Cursor and Antigravity share the same base, so the platform integration works the same everywhere; Cursor and Antigravity bring the AI agent along, in VS Code you work with Claude Code or Codex in the terminal.
Opening a project
From the setup app you open a project with one click in the default tool set there, or by hand via ~/Documents/application-platform/<organization-slug>/<project-slug>; open the project folder, not a single repository, so all repositories are visible and the shared configuration applies.
The Application Platform extension
The setup app installs the extension doppelt-digital.application-platform in VS Code, Cursor and Antigravity; the workspace configuration recommends it if missing. Its welcome page shows all repositories with description, tech stack, recommended files and links to GitLab, Sentry and this documentation; a button per repository starts ap run-local, plus quick links to the web interface and AI tools and a decrypted view of deployment configuration.
Configuration from local-configuration
The files from local-configuration are symlinked into the project folder; if you change them there and push, they apply to the whole team.
| Folder or file | Effect |
|---|---|
.vscode/ |
Extension recommendations and editor settings |
.cursor/rules/ |
Cursor rules, including the platform guidelines |
.antigravity/ |
Agent rules for Antigravity |
AGENTS.md |
Central instructions read by all AI tools |
The agent in Cursor and Antigravity thus follows the platform conventions from AGENTS.md; you add your own rules under Your own rules for AI agents.
Agent plugin in Cursor
For the agent to create or import projects, install the agent plugin via Customize → Plugins or with npx plugins add doppelt-digital/application-platform-plugin -s user -y and reload the window (Developer: Reload Window); installation routes, tools and failure cases are in CLI and agent plugin.
