## Summary - **SDK (`dev` & `dev --once`)**: After app registration, the CLI now obtains an `APPLICATION_ACCESS` token via `client_credentials` grant using the app's own `clientId`/`clientSecret`, and uses that token for CoreApiClient schema introspection — instead of the user's `config.accessToken` which returns the full unscoped schema. - **Config**: `oauthClientSecret` is now persisted alongside `oauthClientId` in `~/.twenty/config.json` when creating a new app registration, so subsequent `dev`/`dev --once` runs can obtain fresh app tokens without re-registration. - **CI action**: `spawn-twenty-app-dev-test` now outputs a proper `API_KEY` JWT (signed with the seeded dev workspace secret) instead of the previous hardcoded `ACCESS` token — giving consumers a real API key rather than a user session token. ## Motivation When developing Twenty apps, `yarn twenty dev` was using the CLI user's OAuth token for GraphQL schema introspection during CoreApiClient generation. This token (type `ACCESS`) has no `applicationId` claim, so the server returns the **full workspace schema** — including all objects — rather than the scoped schema the app should see at runtime (filtered by `applicationId`). This caused a discrepancy: the generated CoreApiClient contained fields the app couldn't actually query at runtime with its `APPLICATION_ACCESS` token. By switching to `client_credentials` grant, the SDK now introspects with the same token type the app will use in production, ensuring the generated client accurately reflects the app's runtime capabilities.

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
