Copilot Agent Advisor
Not sure whether a scenario needs a full custom agent, a lightweight standard agent, or nothing more than Microsoft 365 Copilot as it ships? This skill makes that call for you.
Describe the scenario and it recommends one of three options:
| Option | What it is |
|---|---|
| Use Microsoft 365 Copilot as-is | The built-in Copilot experience over your Microsoft 365 data — no build. |
| Standard agent (declarative) | Copilot tailored with your instructions, knowledge, and actions, running on Copilot’s own orchestrator and models, inside Microsoft 365 apps. |
| Custom agent (custom engine) | A fully custom agent — your own orchestrator and models, custom workflows, its own hosting, and reach beyond Microsoft 365. |
It also advises which Copilot Studio harness to build on — the GitHub Copilot harness (reasoning-heavy, multi-step work), the standard harness (rule-based and predictable), or the Copilot chat harness (extending Microsoft 365 Copilot Chat) — and flags that agents aren’t transferable between the GitHub Copilot and standard harnesses.
How it works
It weighs the factors that actually drive the decision:
- Where the knowledge/data lives (Microsoft 365 vs external systems)
- Whether you need your own or fine-tuned models
- Whether you need custom orchestration or deterministic business logic
- Channels (inside Microsoft 365 only, or external too)
- Autonomy (user-initiated vs proactive/triggered)
- Audience (individual vs group collaboration)
- Compliance (inherit Microsoft 365’s, or own it)
- Speed & skill (fastest low-code, or full pro-code control)
Then it returns a clear recommendation with the reasoning tied to your specifics, a runner-up and the single factor that would flip the decision, how to build it, and the trade-offs (cost, hosting, compliance ownership).
Example
You: “We want a Teams helpdesk assistant that answers from our SharePoint IT policies. Which agent should I build?”
It recommends: a standard (declarative) knowledge agent in Microsoft 365 Copilot Agent Builder — because the knowledge already lives in Microsoft 365, it runs inside Teams, it’s user-initiated, and it inherits Microsoft 365 compliance. Runner-up (custom engine agent) only if you later add external-system write-back, your own model, or proactive behavior.
Good to know
- It advises — it doesn’t build. It recommends the choice; it won’t provision, configure, or deploy the agent.
- It stays current. Agent capabilities and previews move fast, so it verifies fast-moving specifics against Microsoft Learn before asserting them.
- Works everywhere. Platform-neutral — the same advisory logic runs in Cowork, Copilot Studio, and Scout, with no dependency on platform-specific tools.
- Grounded in Microsoft Learn’s declarative-vs-custom-engine decision guidance and the Copilot Studio harnesses overview (GitHub Copilot, standard, and Copilot chat harnesses).
