Auto-mode Selection: Let Copilot Intelligently Choose Between Agent, Ask, and Plan Modes

[Fahad090NP]

Problem

Users must manually select between Agent, Ask, and Plan modes before each interaction. Real-world tasks rarely fit into a single mode — a single prompt can require clarification (Ask), structured thinking (Plan), and code execution (Agent) all at once. Forcing users to pre-select a mode means they either get a partial response or have to split one natural task across multiple sessions.

Proposed Solution

Introduce an Auto mode where Copilot doesn't just pick one mode — it combines the expertise of all three modes within a single response to a single prompt.

For example, "Help me redesign and implement the payment flow" should:

1. Ask — clarify scope and requirements if the prompt is ambiguous
2. Plan — break down the approach into steps
3. Agent — execute the implementation

This unified experience should be the default, with manual mode selection still available as an override.

Benefits

• Copilot will have access to the full expertise of all modes (Agent, Ask, and Plan)
• A single prompt can fully leverage Agent, Ask, and Plan together
• Eliminates artificial boundaries between modes for complex tasks
• Reduces friction and decision fatigue, especially for newer users
• Accomplishes more in fewer interactions, reducing premium quota consumption

Suggested UX

• Add "Auto" as the default option in the mode selector
• Optionally show which modes were activated
