或者使用Python

pip install microsoft-agent-framework pip install microsoft-agent-skills

2. 项目配置

<!-- .csproj文件配置 -->
<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <Nullable>enable</Nullable>
  </PropertyGroup>

<ItemGroup> <PackageReference Include="Microsoft.Agent.Framework" Version="1.0.0" /> <PackageReference Include="Microsoft.Agent.Skills" Version="1.0.0" /> </ItemGroup> </Project>

一步步集成Agent Skills

步骤1:创建基础Agent

using Microsoft.Agent.Framework;
using Microsoft.Agent.Framework.Agents;

// 创建基础Agent public class MyFirstAgent : AgentBase { public MyFirstAgent(string name) : base(name) { // 初始化配置 Configure(options => { options.EnableMemory = true; options.MaxConcurrentTasks = 5; options.LogLevel = LogLevel.Information; }); }

protected override async Task OnInitializeAsync() { await base.OnInitializeAsync(); Console.WriteLine($"Agent '{Name}' initialized successfully."); } }

步骤2:定义Skill接口

using Microsoft.Agent.Framework.Skills;

// 定义Skill接口 public interface ICalculatorSkill : ISkill { Task<double> AddAsync(double a, double b); Task<double> MultiplyAsync(double a, double b); Task<double> DivideAsync(double a, double b); }

// Skill属性配置 [SkillMetadata( Name = "Calculator", Description = "提供基础数学计算功能", Version = "1.0.0", Author = "Your Name", Category = "Utilities" )] public class CalculatorSkill : SkillBase, ICalculatorSkill { public CalculatorSkill() : base("calculator") { }

public async Task<double> AddAsync(double a, double b) { LogInformation($"Calculating {a} + {b}"); return await Task.FromResult(a + b); }

public async Task<double> MultiplyAsync(double a, double b) { LogInformation($"Calculating {a} * {b}"); return await Task.FromResult(a * b); }

public async Task<double> DivideAsync(double a, double b) { if (Math.Abs(b) < double.Epsilon) throw new DivideByZeroException("Cannot divide by zero");

LogInformation($"Calculating {a} / {b}"); return await Task.FromResult(a / b); }

protected override Task OnInitializeAsync() { Console.WriteLine($"Skill '{Name}' initialized."); return Task.CompletedTask; } }

步骤3:注册和使用Skills

using Microsoft.Agent.Framework;
using Microsoft.Agent.Framework.Agents;
using Microsoft.Agent.Framework.Skills;

class Program { static async Task Main(string[] args) { // 创建Agent实例 var agent = new MyFirstAgent("MathAssistant");

// 初始化Agent await agent.InitializeAsync();

// 创建并注册Calculator Skill var calculatorSkill = new CalculatorSkill(); await agent.RegisterSkillAsync(calculatorSkill);

// 创建并注册其他Skills var weatherSkill = new WeatherSkill(); var webSearchSkill = new WebSearchSkill();

await agent.RegisterSkillAsync(weatherSkill); await agent.RegisterSkillAsync(webSearchSkill);

// 使用Skill var result = await agent.ExecuteSkillAsync<double>( "calculator", "AddAsync", new { a = 10.5, b = 20.3 } );

Console.WriteLine($"计算结果: {result}");

// 列出所有注册的Skills var skills = await agent.GetRegisteredSkillsAsync(); Console.WriteLine($"已注册Skills: {string.Join(", ", skills.Select(s => s.Name))}"); } }

步骤4:实现复杂Skill - 天气查询

using System.Net.Http;
using System.Text.Json;
using Microsoft.Agent.Framework.Skills;

[SkillMetadata( Name = "Weather", Description = "查询城市天气信息", Version = "1.0.0", Author = "Your Name", Category = "Services" )] public class WeatherSkill : SkillBase { private readonly HttpClient _httpClient; private readonly string _apiKey;

public WeatherSkill() : base("weather") { _httpClient = new HttpClient(); _apiKey = Environment.GetEnvironmentVariable("WEATHER_API_KEY") ?? throw new InvalidOperationException("Weather API key not found"); }

[SkillFunction("获取城市天气")] public async Task<WeatherInfo> GetWeatherAsync(string city, string country = "CN") { try { LogInformation($"查询{city}的天气信息");

var url = $"https://api.weather.com/v1/{country}/{city}/current"; var request = new HttpRequestMessage(HttpMethod.Get, url); request.Headers.Add("X-API-Key", _apiKey);

var response = await _httpClient.SendAsync(request); response.EnsureSuccessStatusCode();

var json = await response.Content.ReadAsStringAsync(); var weatherData = JsonSerializer.Deserialize<WeatherApiResponse>(json);

return new WeatherInfo { City = city, Country = country, Temperature = weatherData?.Temperature ?? 0, Humidity = weatherData?.Humidity ?? 0, Condition = weatherData?.Condition ?? "Unknown", LastUpdated = DateTime.UtcNow }; } catch (Exception ex) { LogError($"获取天气信息失败: {ex.Message}"); throw new SkillExecutionException($"无法获取{city}的天气信息", ex); } }

[SkillFunction("获取天气预报")] public async Task<WeatherForecast[]> GetForecastAsync(string city, int days = 3) { // 实现天气预报逻辑 return await Task.FromResult(new WeatherForecast[days]); }

protected override async Task OnInitializeAsync() { await base.OnInitializeAsync(); Console.WriteLine($"Weather Skill '{Name}' 初始化完成"); }

protected override async Task OnDisposeAsync() { _httpClient?.Dispose(); await base.OnDisposeAsync(); } }

// 数据模型 public class WeatherInfo { public string City { get; set; } public string Country { get; set; } public double Temperature { get; set; } public double Humidity { get; set; } public string Condition { get; set; } public DateTime LastUpdated { get; set; } }

public class WeatherApiResponse { public double Temperature { get; set; } public double Humidity { get; set; } public string Condition { get; set; } }

步骤5:Skill依赖管理

using Microsoft.Agent.Framework.Skills;

// 具有依赖关系的Skill [SkillMetadata( Name = "TravelAssistant", Description = "旅行助手,整合多个服务", Version = "1.0.0", Dependencies = new[] { "weather", "calculator", "maps" } )] public class TravelAssistantSkill : SkillBase { private readonly ISkill _weatherSkill; private readonly ISkill _calculatorSkill; private readonly ISkill _mapsSkill;

public TravelAssistantSkill( ISkill weatherSkill, ISkill calculatorSkill, ISkill mapsSkill) : base("travel-assistant") { _weatherSkill = weatherSkill ?? throw new ArgumentNullException(nameof(weatherSkill)); _calculatorSkill = calculatorSkill ?? throw new ArgumentNullException(nameof(calculatorSkill)); _mapsSkill = mapsSkill ?? throw new ArgumentNullException(nameof(mapsSkill)); }

[SkillFunction("规划旅行")] public async Task<TravelPlan> PlanTravelAsync( string origin, string destination, DateTime travelDate) { LogInformation($"规划从{origin}到{destination}的旅行");

// 使用Weather Skill查询天气 var weatherInfo = await _weatherSkill.ExecuteAsync<WeatherInfo>( "GetWeatherAsync", new { city = destination } );

// 使用Maps Skill计算距离 var distance = await _mapsSkill.ExecuteAsync<double>( "CalculateDistance", new { from = origin, to = destination } );

// 使用Calculator Skill估算费用 var estimatedCost = await _calculatorSkill.ExecuteAsync<double>( "MultiplyAsync", new { a = distance, b = 0.5 } // 假设每公里0.5元 );

return new TravelPlan { Origin = origin, Destination = destination, TravelDate = travelDate, Weather = weatherInfo, Distance = distance, EstimatedCost = estimatedCost, CreatedAt = DateTime.UtcNow }; } }

public class TravelPlan { public string Origin { get; set; } public string Destination { get; set; } public DateTime TravelDate { get; set; } public WeatherInfo Weather { get; set; } public double Distance { get; set; } public double EstimatedCost { get; set; } public DateTime CreatedAt { get; set; } }

步骤6:Skill配置管理

using Microsoft.Agent.Framework.Configuration;
using Microsoft.Extensions.Configuration;

// 可配置的Skill public class ConfigurableSkill : SkillBase { private readonly SkillConfiguration _configuration;

public ConfigurableSkill(IConfiguration configuration) : base("configurable") { _configuration = configuration.GetSection("Skills:Configurable") .Get<SkillConfiguration>() ?? new SkillConfiguration(); }

[SkillFunction("可配置操作")] public async Task<string> ExecuteConfigurableOperationAsync(string input) { var result = new StringBuilder();

if (_configuration.EnableLogging) { result.AppendLine($"[LOG] 开始处理: {input}"); }

// 执行核心逻辑 var processed = ProcessInput(input, _configuration.ProcessingMode); result.AppendLine(processed);

if (_configuration.EnableValidation) { var validationResult = ValidateResult(processed, _configuration.ValidationRules); result.AppendLine($"[VALIDATION] {validationResult}"); }

return await Task.FromResult(result.ToString()); }

private string ProcessInput(string input, ProcessingMode mode) { return mode switch { ProcessingMode.Uppercase => input.ToUpper(), ProcessingMode.Lowercase => input.ToLower(), ProcessingMode.Reverse => new string(input.Reverse().ToArray()), _ => input }; }

private string ValidateResult(string result, ValidationRules rules) { if (result.Length < rules.MinLength) return $"验证失败: 长度小于{rules.MinLength}";

if (result.Length > rules.MaxLength) return $"验证失败: 长度大于{rules.MaxLength}";

return "验证通过"; } }

public class SkillConfiguration { public bool EnableLogging { get; set; } = true; public bool EnableValidation { get; set; } = true; public ProcessingMode ProcessingMode { get; set; } = ProcessingMode.Uppercase; public ValidationRules ValidationRules { get; set; } = new(); }

public enum ProcessingMode { Uppercase, Lowercase, Reverse }

public class ValidationRules { public int MinLength { get; set; } = 1; public int MaxLength { get; set; } = 1000; }

高级集成技巧

1. Skill生命周期管理

public class LifecycleManagedSkill : SkillBase
{
    private Timer _healthCheckTimer;

public LifecycleManagedSkill() : base("lifecycle-managed") { }

protected override async Task OnInitializeAsync() { await base.OnInitializeAsync();

// 初始化定时健康检查 _healthCheckTimer = new Timer(HealthCheckCallback, null, TimeSpan.FromMinutes(1), TimeSpan.FromMinutes(5));

LogInformation("Skill初始化完成,健康检查已启动"); }

protected override async Task OnActivateAsync() { await base.OnActivateAsync(); LogInformation("Skill已激活"); }

protected override async Task OnDeactivateAsync() { await base.OnDeactivateAsync(); LogInformation("Skill已停用"); }

protected override async Task OnDisposeAsync() { _healthCheckTimer?.Dispose(); await base.OnDisposeAsync(); LogInformation("Skill资源已释放"); }

private void HealthCheckCallback(object state) { try { // 执行健康检查 LogDebug("执行健康检查..."); // 检查依赖服务状态等 } catch (Exception ex) { LogError($"健康检查失败: {ex.Message}"); } } }

2. Skill版本管理

[SkillMetadata(
    Name = "VersionedSkill",
    Description = "支持版本管理的Skill",
    Version = "2.1.0",
    MinFrameworkVersion = "1.2.0",
    MaxFrameworkVersion = "2.0.0"
)]
public class VersionedSkill : SkillBase
{
    private readonly Dictionary<string, Func<object, Task<object>>> _versionedFunctions;

public VersionedSkill() : base("versioned") { _versionedFunctions = new Dictionary<string, Func<object, Task<object>>> { ["1.0.0"] = async (input) => await ProcessV1Async(input), ["2.0.0"] = async (input) => await ProcessV2Async(input), ["2.1.0"] = async (input) => await ProcessV2_1Async(input) }; }

[SkillFunction("版本化处理", SupportedVersions = new[] { "1.0.0", "2.0.0", "2.1.0" })] public async Task<string> ProcessAsync(string input, string version = "2.1.0") { if (!_versionedFunctions.TryGetValue(version, out var processor)) { throw new SkillVersionException($"版本{version}不受支持"); }

var result = await processor(input); return result.ToString(); }

private async Task<object> ProcessV1Async(object input) { // V1版本处理逻辑 return await Task.FromResult($"V1: {input}"); }

private async Task<object> ProcessV2Async(object input) { // V2版本处理逻辑 return await Task.FromResult($"V2: {input}"); }

private async Task<object> ProcessV2_1Async(object input) { // V2.1版本处理逻辑 return await Task.FromResult($"V2.1: {input}"); } }

3. 异步Skill链

public class SkillChainOrchestrator
{
    private readonly IServiceProvider _serviceProvider;

public SkillChainOrchestrator(IServiceProvider serviceProvider) { _serviceProvider = serviceProvider; }

public async Task<TResult> ExecuteSkillChainAsync<TResult>( SkillChainDefinition chainDefinition, object initialInput) { var context = new SkillChainContext { Input = initialInput, Results = new Dictionary<string, object>(), CurrentStep = 0 };

foreach (var step in chainDefinition.Steps) { try { LogInformation($"执行Skill链步骤: {step.SkillName}.{step.FunctionName}");

var skill = _serviceProvider.GetRequiredService<ISkill>(step.SkillName); var result = await skill.ExecuteAsync<object>( step.FunctionName, context.Input );

context.Results[step.Name] = result; context.Input = result; // 将结果作为下一步的输入 context.CurrentStep++; } catch (Exception ex) { if (step.IsRequired) { LogError($"必需步骤失败: {step.Name}, 错误: {ex.Message}"); throw new SkillChainException($"Skill链执行失败于步骤: {step.Name}", ex); } else { LogWarning($"可选步骤失败: {step.Name}, 继续执行后续步骤"); context.Results[step.Name] = null; } } }

return (TResult)context.Input; } }

public class SkillChainDefinition { public List<SkillChainStep> Steps { get; set; } = new(); }

public class SkillChainStep { public string Name { get; set; } public string SkillName { get; set; } public string FunctionName { get; set; } public bool IsRequired { get; set; } = true; public TimeSpan? Timeout { get; set; } }

public class SkillChainContext { public object Input { get; set; } public Dictionary<string, object> Results { get; set; } public int CurrentStep { get; set; } }

测试和调试

单元测试Skills

using Xunit;
using Microsoft.Agent.Framework.Skills;

public class CalculatorSkillTests { [Fact] public async Task AddAsync_ShouldReturnCorrectSum() { // 准备 var skill = new CalculatorSkill(); await skill.InitializeAsync();

// 执行 var result = await skill.AddAsync(10, 20);

// 断言 Assert.Equal(30, result); }

[Theory] [InlineData(10, 20, 30)] [InlineData(-5, 10, 5)] [InlineData(0, 0, 0)] public async Task AddAsync_WithVariousInputs_ShouldReturnCorrectResults( double a, double b, double expected) { // 准备 var skill = new CalculatorSkill(); await skill.InitializeAsync();

// 执行 var result = await skill.AddAsync(a, b);

// 断言 Assert.Equal(expected, result); }

[Fact] public async Task DivideAsync_WithZeroDivisor_ShouldThrowException() { // 准备 var skill = new CalculatorSkill(); await skill.InitializeAsync();

// 执行和断言 await Assert.ThrowsAsync<DivideByZeroException>( () => skill.DivideAsync(10, 0) ); } }

集成测试

public class AgentIntegrationTests : IAsyncLifetime
{
    private MyFirstAgent _agent;

public async Task InitializeAsync() { // 测试前初始化 _agent = new MyFirstAgent("TestAgent"); await _agent.InitializeAsync();

// 注册测试Skills await _agent.RegisterSkillAsync(new CalculatorSkill()); await _agent.RegisterSkillAsync(new WeatherSkill()); }

[Fact] public async Task Agent_WithMultipleSkills_ShouldExecuteCorrectly() { // 执行Skill链 var calculatorResult = await _agent.ExecuteSkillAsync<double>( "calculator", "MultiplyAsync", new { a = 5, b = 6 } );

Assert.Equal(30, calculatorResult);

// 验证Skill注册 var skills = await _agent.GetRegisteredSkillsAsync(); Assert.Contains(skills, s => s.Name == "calculator"); Assert.Contains(skills, s => s.Name == "weather"); }

[Fact] public async Task Agent_WithInvalidSkill_ShouldHandleGracefully() { // 尝试执行不存在的Skill var exception = await Record.ExceptionAsync( () => _agent.ExecuteSkillAsync<object>( "nonexistent", "SomeFunction", new { } ) );

Assert.NotNull(exception); Assert.IsType<SkillNotFoundException>(exception); }

public async Task DisposeAsync() { // 测试后清理 if (_agent != null) { await _agent.DisposeAsync(); } } }

[SkillFunction("监控的操作")] public async Task<string> MonitoredOperationAsync(string input) { var stopwatch = Stopwatch.StartNew(); var operationId = Guid.NewGuid().ToString();

try { _metricsCollector.RecordOperationStart(operationId, Name, "MonitoredOperation");

// 执行实际操作 var result = await ExecuteCoreOperationAsync(input);

stopwatch.Stop();

_metricsCollector.RecordOperationSuccess( operationId, stopwatch.ElapsedMilliseconds, result.Length );

return result; } catch (Exception ex) { stopwatch.Stop();

_metricsCollector.RecordOperationFailure( operationId, stopwatch.ElapsedMilliseconds, ex );

throw; } }

private async Task<string> ExecuteCoreOperationAsync(string input) { // 模拟耗时操作 await Task.Delay(100); return $"处理后的: {input.ToUpper()}"; } }
