Palantir OSDK First Read and Validated Action

Overview

Prove the smallest safe vertical slice: Developer Console application, generated OSDK, authenticated client, bounded object read, and an optional validation-only Action. Avoid mixing the Platform SDK, OSDK, transforms, and deployment in the first proof.

Prerequisites

• Choose a non-production Foundry environment and a low-sensitivity object type with a few synthetic or approved test objects.
• Identify the application owner, Ontology owner, OSDK language, user-delegated or backend-service grant, and selected Ontology resources.
• Read references/official-docs.md plus the generated application-specific documentation in Developer Console.
• Prepare an approved Action only if validation-only behavior is available and no production write is required.

Current Contract

• Developer Console creates and manages OSDK applications and generates language-specific packages for selected Ontology resources.
• The generated OSDK exposes the actual object types, links, Actions, and Functions selected for that application.
• An OSDK application authenticates with OAuth as a public/confidential user application or backend service, according to its design.
• A first read should be bounded by filters, selected properties, deterministic ordering, and pagination.
