Anthropic PDF: 8 layers to build a Claude Duet-style proactive agent
A 15-page PDF lays out the formula context + watch + judgment + gate across 8 layers, with schemas, pseudocode and a 10-day build path.
Anthropic just dropped a 15-page PDF on building your own Claude Duet - 8 layers to an agent that works while you sleep and texts you first: the formula: Proactive Agent = Context + Watch + Judgment + Gate here's how to build your own in 8 layers: layer 1 → context - one thread + your rules stored word for word. no memory without a source layer 2 → watch - one event schema for every app. a dedupe key turns 14 error pings into 1 event layer 3 → judge - anomaly score in code, then the model fills an 8-field rubric. no evidence link, no P0 layer 4 → speak - 1 brief at 8am. alerts only for P0. max 3 interruptions a day layer 5 → prepare - every overnight task gets a sandbox, a turn budget and a finish line layer 6 → gate - every action is 1 packet: exact payload, what can't be undone, expiry. nothing runs without your yes layer 7 → defend - fetched text is data, never orders. a broker holds the passwords, not the model layer 8 → learn - every skip raises the threshold 15%. P0 has a floor it can never learn past the result: replay 30 days of real events before it texts anyone. miss 1 P0 and it doesn't ship this 15-page PDF has the schemas, the pseudocode and a 10-day build path bookmark the PDF to build your own - the full course on using Duet is in the article below ↓
