Microsoft Skill Creator

Create hybrid skills for Microsoft technologies that store essential knowledge locally while enabling dynamic Learn MCP lookups for deeper details.

About Skills

Skills are modular packages that extend agent capabilities with specialized knowledge and workflows. A skill transforms a general-purpose agent into a specialized one for a specific domain.

Skill Structure

├── SKILL.md (required)     # Frontmatter (name, description) + instructions
├── references/             # Documentation loaded into context as needed

Key Principles

Learn MCP Tools

| Tool | Purpose | When to Use | |------|---------|-------------| | microsoft_docs_search | Search official docs | First pass discovery, finding topics | | microsoft_docs_fetch | Get full page content | Deep dive into important pages | | microsoft_code_sample_search | Find code examples | Get implementation patterns |

CLI Alternative

If the Learn MCP server is not available, use the mslearn CLI from the command line instead:

# Run directly (no install needed)
npx @microsoft/learn-cli search "semantic kernel overview"
Or install globally, then run
npm install -g @microsoft/learn-cli
mslearn search "semantic kernel overview"

| MCP Tool | CLI Command | |----------|-------------| | microsoft_docs_search(query: "...") | mslearn search "..." | | microsoft_code_sample_search(query: "...", language: "...") | mslearn code-search "..." --language ... | | microsoft_docs_fetch(url: "...") | mslearn fetch "..." |

Generated skills should include this same CLI fallback table so agents can use either path.

Creation Process

Step 1: Investigate the Topic

Build deep understanding using Learn MCP tools in three phases:

Phase 1 - Scope Discovery:

microsoft_docs_search(query="{technology} overview what is")
microsoft_docs_search(query="{technology} concepts architecture")
microsoft_docs_search(query="{technology} getting started tutorial")

Phase 2 - Core Content:

microsoft_docs_fetch(url="...")  # Fetch pages from Phase 1
microsoft_code_sample_search(query="{technology}", language="{lang}")

Phase 3 - Depth:

microsoft_docs_search(query="{technology} best practices")
microsoft_docs_search(query="{technology} troubleshooting errors")

#### Investigation Checklist

After investigating, verify:

Step 2: Clarify with User

Present findings and ask: 1. "I found these key areas: [list]. Which are most important?" 2. "What tasks will agents primarily perform with this skill?" 3. "Which programming language should code samples prioritize?"

Step 3: Generate the Skill

Use the appropriate template from skill-templates.md:

| Technology Type | Template | |-----------------|----------| | Client library, NuGet/npm package | SDK/Library | | Azure resource | Azure Service | | App development framework | Framework/Platform | | REST API, protocol | API/Protocol |

#### Generated Skill Structure

{skill-name}/
├── SKILL.md                    # Core knowledge + Learn MCP guidance
├── references/                 # Detailed local documentation (if needed)
└── sample_codes/               # Working code examples
    ├── getting-started/
    └── common-patterns/

Step 4: Balance Local vs Dynamic Content

Store locally when:

Keep dynamic when:

#### Content Guidelines

| Content Type | Local | Dynamic | |--------------|-------|---------| | Core concepts (3-5) | ✅ Full | | | Hello world code | ✅ Full | | | Common patterns (3-5) | ✅ Full | | | Top API methods | Signature + example | Full docs via fetch | | Best practices | Top 5 bullets | Search for more | | Troubleshooting | | Search queries | | Full API reference | | Doc links |

Step 5: Validate

1. Review: Is local content sufficient for common tasks? 2. Test: Do suggested search queries return useful results? 3. Verify: Do code samples run without errors?

Common Investigation Patterns

For SDKs/Libraries

"{name} overview" → purpose, architecture
"{name} getting started quickstart" → setup steps
"{name} API reference" → core classes/methods
"{name} samples examples" → code patterns
"{name} best practices performance" → optimization

For Azure Services

"{service} overview features" → capabilities
"{service} quickstart {language}" → setup code
"{service} REST API reference" → endpoints
"{service} SDK {language}" → client library
"{service} pricing limits quotas" → constraints

For Frameworks/Platforms

"{framework} architecture concepts" → mental model
"{framework} project structure" → conventions
"{framework} tutorial walkthrough" → end-to-end flow
"{framework} configuration options" → customization

Example: Creating a "Semantic Kernel" Skill

Investigation

microsoft_docs_search(query="semantic kernel overview")
microsoft_docs_search(query="semantic kernel plugins functions")
microsoft_code_sample_search(query="semantic kernel", language="csharp")
microsoft_docs_fetch(url="https://learn.microsoft.com/semantic-kernel/overview/")

description: Build AI agents with Microsoft Semantic Kernel. Use for LLM-powered apps with plugins, planners, and memory in .NET or Python.
Semantic Kernel
Orchestration SDK for integrating LLMs into applications with plugins, planners, and memory.
Key Concepts
Kernel: Central orchestrator managing AI services and plugins
Plugins: Collections of functions the AI can call
Planner: Sequences plugin functions to achieve goals
Memory: Vector store integration for RAG patterns
