Generate a complete TypeSpec declarative agent for Microsoft 365 Copilot with instructions, capabilities, and conversation starters. Produces a main.tsp file with agent declaration, instructions, conversation starters, and capability definitions following Microsoft's TypeSpec M365 Copilot schema Supports 10 capability types including WebSearch, OneDriveAndSharePoint, TeamsMessages, Email, People, CodeInterpreter, GraphicArt, GraphConnectors, Dataverse, and Meetings with optional scoping (URLs, folders, sites) Enforces constraints: agent names under 100 characters, descriptions under 1,000 characters, instructions under 8,000 characters, and 2-4 diverse conversation starters per agent Guides users through discovery questions about agent purpose, required capabilities, knowledge sources, and typical interactions to inform the generated definition

Create TypeSpec Declarative Agent

Create a complete TypeSpec declarative agent for Microsoft 365 Copilot with the following structure:

Requirements

Generate a main.tsp file with:

Agent Declaration

Use @agent decorator with a descriptive name and description

Name should be 100 characters or less

Description should be 1,000 characters or less

Instructions

Use @instructions decorator with clear behavioral guidelines

Define the agent's role, expertise, and personality

Specify what the agent should and shouldn't do

Keep under 8,000 characters

Conversation Starters

Include 2-4 @conversationStarter decorators

Each with a title and example query

Make them diverse and showcase different capabilities

Capabilities (based on user needs)

WebSearch - for web content with optional site scoping

OneDriveAndSharePoint - for document access with URL filtering

TeamsMessages - for Teams channel/chat access

Email - for email access with folder filtering

People - for organization people search

CodeInterpreter - for Python code execution

GraphicArt - for image generation

GraphConnectors - for Copilot connector content

Dataverse - for Dataverse data access

Meetings - for meeting content access

Template Structure

import "@typespec/http";

import "@typespec/openapi3";

import "@microsoft/typespec-m365-copilot";

using TypeSpec.Http;

using TypeSpec.M365.Copilot.Agents;

@agent({

  name: "[Agent Name]",

  description: "[Agent Description]"

})

@instructions("""

  [Detailed instructions about agent behavior, role, and guidelines]

""")

@conversationStarter(#{

  title: "[Starter Title 1]",

  text: "[Example query 1]"

})

@conversationStarter(#{

  title: "[Starter Title 2]",

  text: "[Example query 2]"

})

namespace [AgentName] {

  // Add capabilities as operations here

  op capabilityName is AgentCapabilities.[CapabilityType]<[Parameters]>;

}

Best Practices

Use descriptive, role-based agent names (e.g., "Customer Support Assistant", "Research Helper")

Write instructions in second person ("You are...")

Be specific about the agent's expertise and limitations

Include diverse conversation starters that showcase different features

Only include capabilities the agent actually needs

Scope capabilities (URLs, folders, etc.) when possible for better performance

Use triple-quoted strings for multi-line instructions

Examples

Ask the user:

What is the agent's purpose and role?

What capabilities does it need?

What knowledge sources should it access?

What are typical user interactions?

Then generate the complete TypeSpec agent definition.
