+# SDK
+
+**Status:** Implemented
+**Source:** `src/Sdk/`
+**Owner:** Platform Team
+
+## Purpose
+
+SDK provides code generation and client libraries for integrating with StellaOps APIs. Generates strongly-typed clients from OpenAPI specifications for multiple languages (.NET, TypeScript, Python, Go).
+
+## Components
+
+**Tools:**
+- `StellaOps.Sdk.Generator` - OpenAPI-based client generator
+- `StellaOps.Sdk.Release` - SDK packaging and release automation
+
+**Generated Clients:**
+- .NET (C#) client library
+- TypeScript/JavaScript client
+- Python client (planned)
+- Go client (planned)
+
+## Configuration
+
+SDK generation configured via OpenAPI specs in `docs/api/`.
+
+Key features:
+- Strongly-typed API clients
+- Authentication helpers (OAuth/OIDC, DPoP)
+- Retry and error handling
+- Request/response validation
+- Offline-compatible operation
+
+## Dependencies
+
+- OpenAPI specifications (from all API modules)
+- Authority (authentication flows)
+- Gateway (API routing)
+
+## Related Documentation
+
+- API Reference: `../../09_API_CLI_REFERENCE.md`
+- OpenAPI Specs: `../../api/` (if exists)
+- CLI: `../cli/`
+- Gateway: `../gateway/`
+
+## Current Status
+
+Generator and Release tools implemented. Supports .NET and TypeScript client generation from OpenAPI specs. Used for CLI implementation and Web frontend integration.
