Cornerstone: The Cornerstone Project — Four Desks, One Afternoon
Everything you need to run today is on this page and inside your desk — no instructor walkthrough required. Read this once, then go.
Every desk below is one of the "five moments" from your Day 4 prompt library — now played out as a full working day. Your group gets one desk. Everything you need — the fictional dataset, the brief, and every deliverable — lives inside that one lab page. Nothing here is real Burgan data; nothing you build here should ever be pointed at a real Burgan system.
Start here — before you open a desk
- Get into groups of 4. More than 16 people in the room? Double up — two groups can run the same desk independently and compare notes at presentation time.
- Agree on one desk. If two groups want the same one, whoever decides second picks a different one.
- Check your tools before you start the clock: everyone should have Claude open in a browser tab (same as every day this week), and at least one person in your group should have a free account at gamma.app ready — you'll need it later for your presentation, and it's free to sign up.
- Pick one "scribe" — whoever's laptop holds your group's official answers in the lab page. Everyone else still works in parallel (their own Claude tabs, notes, or scratch paper) — see the "How to split this" tip under every tab inside your desk for exactly how to divide the work so nobody's idle.
- Open your desk below, read the brief, download the dataset, and start with Triage. That's the whole kickoff.
The AML Escalation Desk
Eighteen flagged alerts. One Monday-morning deadline. Build the process, not just the notes.
The Complaint Handover Desk
Sixteen overnight complaints. One morning to triage, draft, and hand each one off safely.
The Credit Committee Desk
Eight loan files. One committee meeting. The number that matters better be checked.
The Overdue-Loan Batch Desk
25 accounts. One afternoon. One instruction that has to work every single time.
Every group's deliverables — same seven, different desk
- Triage — classify this desk's recurring tasks by shape and risk.
- Safety pass — decide what belongs in a prompt and what doesn't, even on fictional data.
- Prompt library — 2-3+ reusable, iterated prompts for this desk's repeating task.
- Agent design — a trigger, instructions, and a guardrail, actually run across the whole dataset.
- Validation log — cross-check the agent's output against the source. Something in every dataset doesn't add up — find it.
- Agent Card — what this agent may do alone, what always needs a human, and what it would take before this pattern could touch a real Burgan system.
- Presentation — a short Gamma.app deck, presented live to the room.
