Auto-switch to Prototype agent when pasting a prototype into a new Elle chat

What is the challenge?

• When starting a new Elle chat, the default agent is selected. If you paste in an Elle prototype, the agent context does not match the content. You have to manually switch to the Prototype agent after pasting.

What is the impact?

• Every user who opens a new chat to iterate on a prototype has to perform an extra manual step before Elle responds usefully. It is a consistent friction point for anyone doing regular prototype work.

Describe your idea.

• When a user pastes content into a new Elle chat, detect whether the pasted content is an Elle prototype. If it is, automatically switch the active agent to the Prototype agent. If the user already has a specific agent selected, do not override it.
