Learned-skill delivery for native Microsoft Agent Framework ChatClientAgent agents. Version 0.1.0 targets .NET 9 and supports Agent Framework >=1.0.0,<2.0.0.

Publication requires a deployed learned-skill delivery API and a published canonical CopilotKit.Intelligence client with GetLearnedSkillsSnapshotAsync. This source checkout uses the canonical client project in the same repository.

Setup

Set CPK_INTELLIGENCE_API_KEY and CPK_INTELLIGENCE_LEARNING_CONTAINER_ID on the server. Set INTELLIGENCE_API_URL for a self-hosted server. Set CPK_INTELLIGENCE_SKILLS_REVISION to pin one exact revision.

using CopilotKit.Intelligence;
using CopilotKit.Intelligence.AgentFramework;
using Microsoft.Agents.AI;
using Microsoft.Extensions.AI;

// chatClient is your application's IChatClient.
using var skills = new SkillRegistryContextProvider(new SkillRegistryOptions());
try
{
    await skills.InitializeAsync();
}
catch (LearnedSkillsException error)
{
    Console.Error.WriteLine(error.Message);
    // The application remains alive. A later invocation retries the check.
}

var agent = skills.CreateAgent(chatClient, new ChatClientAgentOptions
{
    Name = "support",
    ChatOptions = new() { Instructions = "Follow the application's support policy." }
});
var response = await agent.RunAsync("Help with a refund.");
Console.WriteLine(response.Text);

CreateAgent copies the supplied agent configuration. Existing developer instructions, context providers, and tools remain in place. Each invocation receives a delimited catalog and two native tools: copilotkit_load_skill(skill_name) and copilotkit_read_skill_file(skill_name, path). The tools remain available when the registry is empty. Reads stay inside that invocation's immutable snapshot; supporting files must contain UTF-8 text. Tool errors follow the framework's normal behavior.

Developer instructions outrank learned skills. The adapter asks the model to load relevant skills, but does not guarantee model selection or compliance. It does not execute scripts.

Dependency injection

services.AddCopilotKitIntelligenceSkills(
    "support",
    new SkillRegistryOptions { ContainerId = "your-container" },
    provider => provider.GetRequiredService<IChatClient>(),
    new ChatClientAgentOptions
    {
        ChatOptions = new() { Instructions = "Follow the application's support policy." }
    });

// Resolve both services with the same key.
var skills = serviceProvider.GetRequiredKeyedService<SkillRegistryContextProvider>("support");
await skills.InitializeAsync();
var agent = serviceProvider.GetRequiredKeyedService<AIAgent>("support");

Import Microsoft.Extensions.DependencyInjection for these extensions. DI owns the registered context provider. An injected canonical Intelligence client remains application-owned. To share one registry across several selected agents, call CreateAgent on the same provider. Subagents receive learned skills only when explicitly configured; the adapter does not discover or modify an agent hierarchy.

Lifecycle and status

Explicit configuration overrides environment values. Client accepts an existing canonical IntelligenceClient; its connection configuration is authoritative, and the adapter creates no second HTTP client. FreshnessWindow and RequestTimeout default to five seconds. A zero freshness window checks on every invocation. Debug output is disabled unless Debug is true; diagnostics contain no credentials, response bodies, or skill contents.

InitializeAsync is optional preload. Missed or concurrent initialization shares the same refresh used by invocations. A verified empty snapshot counts as initialized. Cancellation of one waiter does not cancel a shared refresh needed by another invocation.

Status returns immutable Initialized, Revision, Mode, LastCheckedAt, Stale, and LastError fields. LastCheckedAt records the last successful check, including a matching 304 response. Failures throw LearnedSkillsException with stable Code, Message, and Retryable fields; InnerException is available for explicit diagnostics.

A transient failure keeps a previously verified snapshot available with no maximum stale age. Confirmed denial blocks new invocations until a successful authorization check. An invocation already in progress retains its snapshot. Pinned mode still checks access and revocation and never substitutes a different revision. Disposal cancels pending refreshes and releases only an adapter-owned canonical client. There is no disk cache or coordination across registry instances or processes.

Supported native execution

Use CreateAgent or the DI extension for complete invocation checks. Direct attachment through AIContextProviders supplies the catalog and tools, but cannot guard background continuations: Agent Framework skips all context providers for those calls.

The creation helper rejects background responses and continuation tokens with INVALID_CONFIG before model execution. Ordinary new runs, streaming runs, and tool-result resumes with new messages use native framework execution and acquire a new pin. Custom client stacks using UseProvidedChatClientAsIs must supply their own native function-invocation decorator. Arbitrary custom agents are outside the turnkey scope.

Development

From the repository root, with .NET 9 installed:

pnpm nx run intelligence-agent-framework-dotnet:test
pnpm nx run intelligence-agent-framework-dotnet:build
pnpm nx run intelligence-agent-framework-dotnet:pack

Tests use shared snapshot and lifecycle fixtures plus the real ChatClientAgent with a deterministic model client. The native tests cover streaming tool loops, refresh during a run, denial during a pinned run, keyed DI, and continuation guards. Package publication is a separate release step after the canonical client and server prerequisites.
