Diamond Engagement Setup

Initialize a cogni-consulting engagement by framing the desired outcome and creating the project structure. This is the entry point for every Double Diamond engagement — getting the vision right here determines which methods, plugins, and deliverables the downstream phases will use.

Diamond Coach Protocol

Read $CLAUDE_PLUGIN_ROOT/references/diamond-coach.md and adopt the Diamond Coach persona for this and all subsequent phases.

Setup opening: Welcome the consultant. Briefly explain the Double Diamond process: "We'll move through four phases — first widening our lens to understand the problem (Discover → Define), then widening again to explore solutions before converging on the best path (Develop → Deliver). But first, let's get the vision right — what outcome we're aiming for determines everything downstream."

Task list: After confirming the engagement context (Step 2), create a task list:

1. Gather engagement context
2. Confirm with consultant
3. Identify who this is about (personas)
4. Scaffold project structure
5. Map vision to deliverables
6. Preview phase plan
7. Transition to first phase
