Use microsoft_docs_search with the class name, method name, and namespace, such as "BlobClient UploadAsync Azure.Storage.Blobs". For methods with multiple overloads, follow up with microsoft_docs_fetch on the result URL to see full signatures.

Use microsoft_code_sample_search with a task description and language, for example query "upload blob managed identity" with language "python". It returns official working examples you can compare against your own implementation.

Yes, the mslearn CLI is a fallback. Run npx @microsoft/learn-cli search "your query" or install it globally with npm install -g @microsoft/learn-cli, then use mslearn search, code-search, and fetch commands.

Do not use it for conceptual documentation questions, Bicep or Terraform module lookups, or skill creation tasks. It is scoped to verifying Microsoft SDK code, packages, and samples rather than general architecture guidance.
