Agent Framework Skill for Claude

Create Agent with Microsoft Agent Framework

Build AI agents, agentic apps, and multi-agent workflows using Microsoft Agent Framework SDK.

Quick Reference

| Property | Value |

|----------|-------|

| SDK | Microsoft Agent Framework (Python) |

| Patterns | Single Agent, Multi-Agent Workflow |

| Server | Azure AI Agent Server SDK (HTTP) |

| Debug | AI Toolkit Agent Inspector + VSCode |

| Best For | Enterprise agents with type safety, checkpointing, orchestration |

When to Use This Skill

Use when the user wants to:

• Create a new AI agent or agentic application
• Scaffold an agent with tools (MCP, function calling)
• Build multi-agent workflows with orchestration patterns
• Add HTTP server mode to an existing agent
• Configure F5/debug support for VSCode

Defaults

• Language: Python
• SDK: Microsoft Agent Framework (pin version 1.0.0b260107)
• Server: HTTP via Azure AI Agent Server SDK
• Environment: Virtual environment (create or detect existing)

MCP Tools

This skill delegates to microsoft-foundry MCP tools for model and project operations:

| Tool | Purpose |

|------|---------|

| foundry_models_list | Browse model catalog for selection |

| foundry_models_deployments_list | List deployed models for selection |

| foundry_resource_get | Get project endpoint |

Creation Workflow

• Gather context (read agent-as-server.md + debug-setup.md + code samples)
• Select model & configure environment
• Implement agent/workflow code + HTTP server mode + .vscode/ configs
• Install dependencies (venv + requirements.txt)
• Verify startup (Run-Fix loop)
• Documentation

Step 1: Gather Context

Read reference files based on user's request:

Always read these references:

• Server pattern: agent-as-server.md (required — HTTP server is the default)
• Debug setup: debug-setup.md (required — always generate .vscode/ configs)

Read the relevant code sample:

• Code samples: agent-samples.md, workflow-basics.md, workflow-agents.md, or workflow-foundry.md

Model Selection: Use microsoft-foundry skill's model catalog to help user select and deploy a model.

Recommended: Search microsoft/agent-framework on GitHub for advanced patterns.

Step 2: Select Model & Configure Environment

*Decide on the model BEFORE coding.*

If user hasn't specified a model, use microsoft-foundry skill to list deployed models or help deploy one.

ALWAYS create/update .env file:

FOUNDRY_PROJECT_ENDPOINT=<project-endpoint>
FOUNDRY_MODEL_DEPLOYMENT_NAME=<model-deployment-name>

• Standard flow: Populate with real values from user's Foundry project
• Deferred Config: Use placeholders, remind user to update before running

Step 3: Implement Code

All three are required by default:

• Agent/Workflow code: Use gathered context to structure the agent or workflow
• HTTP Server mode: Wrap with Agent-as-Server pattern from agent-as-server.md — this is the default entry point
• Debug configs: Generate .vscode/launch.json and .vscode/tasks.json using templates from debug-setup.md

> ⚠️ Warning: Only skip server mode or debug configs if the user explicitly requests a "minimal" or "no server" setup.

Step 4: Install Dependencies

• Generate/update requirements.txt

  # pin version to avoid breaking changes

  # agent framework
  agent-framework-azure-ai==1.0.0b260107
  agent-framework-core==1.0.0b260107

  # agent server (for HTTP server mode)
  azure-ai-agentserver-core==1.0.0b10
  azure-ai-agentserver-agentframework==1.0.0b10

  # debugging support
  debugpy
  agent-dev-cli

• Use a virtual environment to avoid polluting the global Python installation

> ⚠️ Warning: Never use bare python or pip — always use the venv-activated versions or full paths (e.g., .venv/bin/pip).

Step 5: Verify Startup (Run-Fix Loop)

Enter a run-fix loop until no startup errors:

• Run the main entrypoint using the venv's Python (e.g., .venv/Scripts/python main.py on Windows, .venv/bin/python main.py on macOS/Linux)
• If startup fails: Fix error → Rerun
• If startup succeeds: Stop server immediately

Guardrails:

• ✅ Perform real run to catch startup errors
• ✅ Cleanup after verification (stop HTTP server)
• ✅ Ignore environment/auth/connection/timeout errors
• ❌ Don't wait for user input
• ❌ Don't create separate test scripts
• ❌ Don't mock configuration

Step 6: Documentation

Create/update README.md with setup instructions and usage examples.

Error Handling

| Error | Cause | Resolution |

|-------|-------|------------|

| ModuleNotFoundError | Missing SDK | Run pip install agent-framework-azure-ai==1.0.0b260107 in venv |

| AgentRunResponseUpdate not found | Wrong SDK version | Pin to 1.0.0b260107 (breaking rename in newer versions) |

| Agent name validation error | Invalid characters | Use alphanumeric + hyphens, start/end with alphanumeric, max 63 chars |

| Async credential error | Wrong import | Use azure.identity.aio.DefaultAzureCredential (not azure.identity) |
