Overview

This skill helps a user pick the right way to deliver an AI experience in the Microsoft 365 + Copilot Studio ecosystem. It gathers the handful of factors that actually drive the decision (data sources, models, orchestration, channels, autonomy, collaboration, compliance, and skill/speed), maps them to one of three options, and returns a clear, reasoned recommendation with a runner-up and how to build it. It also advises which Copilot Studio harness (GitHub Copilot, standard, or Copilot chat) to build on.

The three options it chooses between:

Option What it is Use when
Use Microsoft 365 Copilot as-is The built-in Copilot experience over Microsoft Graph data, no build. Built-in capabilities + your Microsoft 365 data already cover the need; you don't need extra knowledge, custom instructions, or actions.
Standard agent (declarative agent) Copilot configured with your instructions, knowledge, and actions, running on Copilot's own orchestrator and foundation models, inside Microsoft 365 apps. You want to tailor Copilot for a focused scenario, stay inside Microsoft 365 (Teams, Outlook, SharePoint, Word), inherit Microsoft 365 compliance/RAI, and ship fast with low-code or a streamlined pro-code path.
Custom agent (custom engine agent) A fully custom agent where you bring your own orchestrator and models, with custom/complex workflows, its own hosting, and multi-channel reach. You need custom orchestration, your own/fine-tuned/domain models, deterministic complex business logic, proactive/autonomous behavior, group collaboration, delivery outside Microsoft 365, or you're integrating an existing external bot.
