⭐ Community Toolkit

This page describes the AppHost APIs in the Aspire Community Toolkit Squad integration. Use the getting started guide for an overview, or see Connect to a Squad team to use its connection string in a service.

Installation

Install the hosting package in your AppHost project:

aspire add communitytoolkit-squad

A Aspire CLI é interativa; escolha o resultado adequado quando solicitado:

Select an integration to add:

> communitytoolkit-squad (CommunityToolkit.Aspire.Hosting.Squad)
> Other results listed as selectable options...

#:package CommunityToolkit.Aspire.Hosting.Squad@*

<PackageReference Include="CommunityToolkit.Aspire.Hosting.Squad" Version="*" />

Add a Squad resource

Call AddSquad with a resource name and the path to the workspace root, the directory containing .squad/. The teamRoot argument is optional and defaults to the current working directory.

TypeScript
C#

import { createBuilder } from './.aspire/modules/aspire.mjs';
import path from 'node:path';

const builder = await createBuilder();
const teamRoot = path.resolve('./research-squad');

const squad = await builder.addSquad('research-squad', { teamRoot });

await builder.build().run();

var builder = DistributedApplication.CreateBuilder(args);
var teamRoot = Path.Combine(builder.AppHostDirectory, "research-squad");

var squad = builder.AddSquad("research-squad", teamRoot);

builder.AddProject<Projects.Api>("api")
    .WithReference(squad);

// After adding all resources, run the app...
builder.Build().Run();

The TypeScript addSquad API is generated from the integration’s exported AddSquad method. The example uses the TypeScript AppHost module generated after package installation. The C# example references the resource from a project so Aspire injects its connection string into that project.

Configure the team root

AddSquad has one required parameter and one optional parameter:

name: the Aspire resource name. Aspire uses this name as the consuming app’s connection string key.
teamRoot: the workspace root path, which contains .squad/. If omitted, the integration uses Directory.GetCurrentDirectory().

At startup, the resource reads .squad/team.md. It recognizes table rows and bullets with bold agent names. If the roster file is missing, or no usable roster names are found, the resource uses a default roster. When .squad/agents/ exists, discovered names are included only when a matching {name}/charter.md file exists.

Dashboard metadata and commands

The Squad resource appears in the Aspire dashboard as a logical resource. Its properties include the workspace location, roster file, decisions file, inbox directory, agent count, discovered agents, protocol (maf-1.0), runtime mode, and capabilities. Aspire assigns the Configured state during resource registration. The lifecycle hook publishes Spawning, Active, and Finished; the resource does not run a process and does not have a service health check.

The resource also adds these dashboard commands:

Refresh Agents reports the roster read at startup. Roster changes take effect after restarting the AppHost.
Open Team Root opens the workspace directory in the system file explorer.
Open Copilot CLI opens a terminal in the workspace and runs copilot --agent squad. Install GitHub Copilot CLI and make copilot available on PATH. On Linux, a supported terminal emulator must also be installed.
Check Inbox counts Markdown files in .squad/decisions/inbox/ and reports the result in the AppHost console.

Exported AppHost API

The package exports the following AppHost API:

API	Description
`AddSquad(string name, string? teamRoot = null)`	Adds a Squad logical resource and returns `IResourceBuilder<SquadResource>`.
`SquadResource(string name, string teamRoot)`	Creates a resource for the named workspace.
`SquadResource.TeamRoot`	Gets the workspace root path.
`SquadResource.Agents`	Gets the discovered agent names.
`SquadResource.ConnectionStringExpression`	Provides the `squad://` connection descriptor.
`SquadTeamAnnotation(string teamRoot, string decisionsMdPath, string inboxDir, string agentRosterFile)`	Creates the resource annotation used by the integration.
`SquadTeamAnnotation.TeamRoot`	Gets the workspace root path stored in the annotation.
`SquadTeamAnnotation.DecisionsMdPath`	Gets the decisions file path stored in the annotation.
`SquadTeamAnnotation.InboxDir`	Gets the decision inbox path stored in the annotation.
`SquadTeamAnnotation.AgentRosterFile`	Gets the roster file path stored in the annotation.

AddSquad attaches the annotation automatically. Create it directly only when working with the resource annotation API.
