Look up Microsoft API references, find working code samples, and verify SDK code is correct. Use when working with Azure SDKs, .NET libraries, or Microsoft APIs—to find the right method, check parameters, get working examples, or troubleshoot errors. Catches hallucinated methods, wrong signatures, and deprecated patterns by querying official docs.

The file

We split this skill into the rules it gives an agent

5 rules. 3 are common, 0 are distinctive, and 2 are very specific to this project.

  • 3

    Common

    Most of the 5 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use microsoft_code_sample_search to get official, working examples:

    line 24
  2. Common:

    Before writing code—find a working pattern to follow

    line 33
  3. Common:

    After errors—compare your code against a known-good sample

    line 34
  4. Very specific:

    Use microsoft_code_sample_search to find working code samples and compare with your implementation.

    line 56
  5. Common:

    Before generating code using Microsoft SDKs, verify it's correct:

    line 77

“Common” is measured: kept by at least 6 in 10 of the 5 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Microsoft Code Reference

Prerequisites: Connect to the Microsoft Learn MCP Server

IMPORTANT: This skill requires the Microsoft Learn MCP Server (type: http, url: https://learn.microsoft.com/api/mcp). If it's not already connected, you MUST install and configure it yourself. Ask the user for permission if needed.

It's a free, official Microsoft-owned MCP, no API key or authentication required.

Tools

NeedToolExample
API method/class lookupmicrosoft_docs_search"BlobClient UploadAsync Azure.Storage.Blobs"
Working code samplemicrosoft_code_sample_searchquery: "upload blob managed identity", language: "python"
Full API referencemicrosoft_docs_fetchFetch URL from microsoft_docs_search (for overloads, full signatures)

Finding Code Samples

Use microsoft_code_sample_search to get official, working examples:

microsoft_code_sample_search(query: "upload file to blob storage", language: "csharp")
microsoft_code_sample_search(query: "authenticate with managed identity", language: "python")
microsoft_code_sample_search(query: "send message service bus", language: "javascript")

When to use:

  • Before writing code—find a working pattern to follow
  • After errors—compare your code against a known-good sample
  • Unsure of initialization/setup—samples show complete context

API Lookups

# Verify method exists (include namespace for precision)
"BlobClient UploadAsync Azure.Storage.Blobs"
"GraphServiceClient Users Microsoft.Graph"

# Find class/interface
"DefaultAzureCredential class Azure.Identity"

# Find correct package
"Azure Blob Storage NuGet package"
"azure-storage-blob pip package"

Fetch full page when method has multiple overloads or you need complete parameter details.

Error Troubleshooting

Use microsoft_code_sample_search to find working code samples and compare with your implementation. For specific errors, use microsoft_docs_search and microsoft_docs_fetch:

Error TypeQuery
Method not found"[ClassName] methods [Namespace]"
Type not found"[TypeName] NuGet package namespace"
Wrong signature"[ClassName] [MethodName] overloads" → fetch full page
Deprecated warning"[OldType] migration v12"
Auth failure"DefaultAzureCredential troubleshooting"
403 Forbidden"[ServiceName] RBAC permissions"

When to Verify

Always verify when:

  • Method name seems "too convenient" (UploadFile vs actual Upload)
  • Mixing SDK versions (v11 CloudBlobClient vs v12 BlobServiceClient)
  • Package name doesn't follow conventions (Azure.* for .NET, azure-* for Python)
  • Using an API for the first time

Validation Workflow

Before generating code using Microsoft SDKs, verify it's correct:

  1. Confirm method or package exists — microsoft_docs_search(query: "[ClassName] [MethodName] [Namespace]")
  2. Fetch full details (for overloads/complex params) — microsoft_docs_fetch(url: "...")
  3. Find working sample — microsoft_code_sample_search(query: "[task]", language: "[lang]")

For simple lookups, step 1 alone may suffice. For complex API usage, complete all three steps.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
