name: microsoft-code-reference description: 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.

Microsoft Code Reference (OnoCoro Customized)

Look up Microsoft API references, find working code samples, and verify SDK code is correct. This skill is customized for OnoCoro C# development, Recovery phase code validation, and PLATEAU SDK integration.

Tools

Finding Code Samples

Use microsoft_code_sample_search to get official, working examples:

Copymicrosoft_code_sample_search(query: "null checking patterns C#", language: "csharp")
microsoft_code_sample_search(query: "async await patterns Recovery phase", language: "csharp")
microsoft_code_sample_search(query: "resource management C# dispose pattern", language: "csharp")
microsoft_code_sample_search(query: "exception handling Unity C#", language: "csharp")

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
• During Recovery phase code review—validate patterns against official standards

API Lookups

Copy# Verify method exists (include namespace for precision)
"Transform.Find() UnityEngine.Transform"
"GetComponent<T>() generic method Unity"
"Instantiate() method signature parameters"

# Find class/interface
"DefaultAzureCredential class Azure.Identity"
"IDisposable interface C# dispose pattern"

# Find correct package
"Azure Blob Storage NuGet package"
"Newtonsoft.Json NuGet package"

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

OnoCoro-Specific Patterns

Recovery Phase Validation

Copy# Null checking patterns
microsoft_code_sample_search(query: "null check guard clause C#", language: "csharp")
microsoft_docs_search(query: "C# null-coalescing operator best practices")

# Transform/Component lookup
microsoft_code_sample_search(query: "Transform.Find() null check pattern", language: "csharp")
microsoft_code_sample_search(query: "GetComponent<T>() error handling", language: "csharp")

PrefabManager Pattern

Copymicrosoft_code_sample_search(query: "resource management singleton pattern C#", language: "csharp")
microsoft_code_sample_search(query: "caching strategy dictionary C#", language: "csharp")
microsoft_docs_search(query: "C# static dictionary performance best practices")

PLATEAU SDK Integration

Copymicrosoft_docs_search(query: ".NET geospatial coordinate transformation")
microsoft_code_sample_search(query: "mesh generation C# procedural", language: "csharp")
microsoft_docs_search(query: "C# large dataset processing performance")

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:

OnoCoro Recovery Phase Workflow

Before Writing Code

1. Search for pattern — microsoft_code_sample_search(query: "[pattern]", language: "csharp")
2. Review official sample — Compare with AGENTS.md standards
3. Implement with confidence that pattern is validated

After NullReferenceException

1. Identify the issue — What object is null?
2. Search for pattern — microsoft_code_sample_search(query: "null check guard clause", language: "csharp")
3. Apply pattern — Add proper null checks with early return
4. Reference .github/instructions/unity-csharp-recovery.instructions.md

During Code Review

1. Check method signature — microsoft_docs_search("[ClassName] [MethodName] signature")
2. Verify pattern — microsoft_code_sample_search("[similar pattern]", language: "csharp")
3. Validate against AGENTS.md compliance

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)
• Using an API for the first time
• In Recovery phase—old code may have deprecated patterns

Validation Workflow

Before generating code or during Recovery merge, 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: "csharp")

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

OnoCoro Code Review Examples

Example 1: Transform.Find() Pattern

Copy// Question: Is this null check pattern correct?
Transform absorbCollider = transform.Find("absorbcollider");
if (absorbCollider == null)
{
    Debug.LogWarning("absorbcollider not found");
    return;
}

Verification Steps:

Copy1. microsoft_docs_search(query: "Transform.Find() null check C# Unity")
2. microsoft_code_sample_search(query: "Transform.Find() error handling", language: "csharp")
3. Confirm pattern matches [.github/instructions/unity-csharp-recovery.instructions.md](../../instructions/unity-csharp-recovery.instructions.md)

Example 2: GetComponent() with Validation

Copy// Question: Should I validate the component exists?
RainAbsorbCtrl rainAbsorb = absorbCollider.GetComponent<RainAbsorbCtrl>();
if (rainAbsorb == null)
{
    Debug.LogWarning("RainAbsorbCtrl component not found");
    return;
}

Verification Steps:

Copy1. microsoft_code_sample_search(query: "GetComponent<T>() null validation pattern", language: "csharp")
2. microsoft_docs_search(query: "Component lifecycle validation best practices")
3. Cross-reference [AGENTS.md](../../../AGENTS.md) Coding Standards section

Example 3: Resource Management Pattern

Copy// Question: Is this the right way to manage prefab caching?
private static Dictionary<PrefabType, GameObject> prefabCache = 
    new Dictionary<PrefabType, GameObject>();

Verification Steps:

Copy1. microsoft_docs_search(query: "C# static dictionary caching patterns performance")
2. microsoft_code_sample_search(query: "singleton pattern static cache C#", language: "csharp")
3. Validate against [.github/instructions/prefab-asset-management.instructions.md](../../instructions/prefab-asset-management.instructions.md)
