+description: Create agent skills for Microsoft technologies using Learn MCP tools. Use when users want to create a skill that teaches agents about any Microsoft technology, library, framework, or service (Azure, .NET, M365, VS Code, Bicep, etc.). Investigates topics deeply, then generates a hybrid skill storing essential knowledge locally while enabling dynamic deeper investigation.

+# 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-name/
+├── SKILL.md (required)     # Frontmatter (name, description) + instructions
+├── references/             # Documentation loaded into context as needed
+├── sample_codes/           # Working code examples
+└── assets/                 # Files used in output (templates, etc.)
+```
+
+### Key Principles
+
+- **Frontmatter is critical**: `name` and `description` determine when the skill triggers—be clear and comprehensive
+- **Concise is key**: Only include what agents don't already know; context window is shared
+- **No duplication**: Information lives in SKILL.md OR reference files, not both
+
+## 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 |
+
+## 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:
+- [ ] Can explain what the technology does in one paragraph
+- [ ] Identified 3-5 key concepts
+- [ ] Have working code for basic usage
+- [ ] Know the most common API patterns
+- [ ] Have search queries for deeper topics
+
+### 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](references/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:**
+- Foundational (needed for any task)
+- Frequently accessed
+- Stable (won't change)
+- Hard to find via search
+
+**Keep dynamic when:**
+- Exhaustive reference (too large)
+- Version-specific
+- Situational (specific tasks only)
+- Well-indexed (easy to search)
+
+#### 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/")
+```

+
+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
