Generate SDK Locally
This skill generates, builds, and tests Azure SDKs locally from TypeSpec with automatic customization support, covering the end-to-end workflow for fixing generation issues, applying SDK-specific updates, and refreshing package metadata when needed.
Triggers
USE FOR: generate, build, and test Azure SDKs locally from TypeSpec with automatic customization; update changelog; fix SDK build errors; fix breaking changes; resolve SDK generation errors; customize TypeSpec; rename SDK client or model; hide operation from SDK; fix analyzer errors; resolve customization drift; create subclient; update metadata; update version

DO NOT USE FOR: publishing to package registries, CI pipeline configuration, API design review
Rules
- Requires the
azure-sdk-mcp server for the MCP workflow; without MCP, use npm exec --prefix eng/common/tsp-client -- tsp-client CLI.
- Verify the target language repo and the correct TypeSpec configuration file before generation.
- After generation or customization, run the check and test steps before updating metadata or finalizing changes.
MCP Tools
| Tool | Purpose |
|---|
azure-sdk-mcp:azsdk_verify_setup | Verify environment |
azure-sdk-mcp:azsdk_package_generate_code | Generate SDK |
azure-sdk-mcp:azsdk_package_build_code | Build package |
azure-sdk-mcp:azsdk_package_run_check | Validate package |
azure-sdk-mcp:azsdk_package_run_tests | Run tests |
azure-sdk-mcp:azsdk_customized_code_update | Apply customizations (includes regeneration and build) |
azure-sdk-mcp:azsdk_package_update_changelog_content | Update changelog |
azure-sdk-mcp:azsdk_package_update_metadata | Update metadata including ci.yml |
azure-sdk-mcp:azsdk_package_update_version | Update version |
Prerequisites: azure-sdk-mcp server must be running. Without MCP, use npx tsp-client CLI.
Steps
- Select language — Confirm target language: .NET, Java, JavaScript, Python, Go, or Rust.
- Verify repo — Ensure the user has a local clone of the correct SDK repo. If not cloned, instruct user to clone it.
- Identify config file — Determine the path to the TypeSpec configuration file. See config file details.
- From
azure-rest-api-specs repo: use path to tspconfig.yaml.
- From an SDK language repo: use path to
tsp-location.yaml.
- Verify setup — Run
azure-sdk-mcp:azsdk_verify_setup to confirm environment.
- Generate — Run
azure-sdk-mcp:azsdk_package_generate_code with the config file path.
- Build — Run
azure-sdk-mcp:azsdk_package_build_code. If build succeeds, proceed to step 8.
- Customize — If build fails, or if user requests SDK modifications, run
azure-sdk-mcp:azsdk_customized_code_update with the build errors or user request. The tool handles the full workflow internally: it classifies the issue, applies TypeSpec decorators and/or code patches, regenerates the SDK, and builds — all in one call. See customization workflow.
- Commit checkpoint — Prompt the user to commit generated changes before proceeding. See commit checkpoint details.
- Validate — Run
azure-sdk-mcp:azsdk_package_run_check and azure-sdk-mcp:azsdk_package_run_tests.
- Metadata — Run
azure-sdk-mcp:azsdk_package_update_changelog_content, azure-sdk-mcp:azsdk_package_update_metadata, and azure-sdk-mcp:azsdk_package_update_version. (Note: For .NET data plane, skip this step — metadata, changelog, and version updates are per-commit tasks, not part of the generate/build/test workflow.)
- Final commit — Prompt the user to commit final changes (changelog, metadata, version). See commit checkpoint details.
SDK repos | Customization workflow | Detailed workflow
Guardrails
- NEVER modify generated SDK code files directly for customizations. Always use
azure-sdk-mcp:azsdk_customized_code_update. It handles classification, TypeSpec decorators, code patches, regeneration, and build as a single atomic workflow.
- If
azure-sdk-mcp:azsdk_customized_code_update fails or times out, report the error to the user and suggest retrying. Do not attempt to replicate its behavior by editing files manually.
- Only the customization tool understands the correct layering of TypeSpec decorators vs code patches and ensures regenerated code stays consistent.
Examples
- "Generate the SDK locally for my TypeSpec service"
- "Build and test the Python SDK package"
- "Run CI checks for my SDK package"
- "Fix the SDK build errors on this PR"
- "The SDK generation has breaking changes, resolve them"
- "Rename FooClient to BarClient for .NET"
- "Hide the internal polling operation from the Python SDK"
- "Fix .NET analyzer errors AZC0030 and AZC0012"
- "The build is failing because a customization references a renamed property"
- "Create a subclient architecture for the Python SDK"
- "Apply TypeSpec customizations to fix compilation errors"
- "Update the changelog for this SDK package"
- "Update the package version"
- "Update the package metadata and ci.yml"
Troubleshooting
- Run
azure-sdk-mcp:azsdk_verify_setup to confirm MCP and tools.
- If build fails with type conflicts, breaking changes, analyzer errors, or customization drift, use
azure-sdk-mcp:azsdk_customized_code_update to apply customizations.
- The customization tool uses a two-phase approach: TypeSpec decorators first (Phase A), then code repairs if needed (Phase B).
- If
azure-sdk-mcp:azsdk_customized_code_update fails or times out, report the error and retry. Do not manually edit generated SDK code — manual edits will be overwritten on the next regeneration.
- Without MCP, use
npx tsp-client CLI.
