On the contracts
Every handoff is a Pydantic-validated schema with explicit status enums and mandatory evidence citations — which is what makes ~40 agents agree with each other.
Multi-agent litigation pipeline
The contracts are the architecture.
Seven staged synthesis steps, roughly forty specialized agents, and a typed payload at every handoff. The diagram below is the thing I would whiteboard in an interview — architecture only, no client data.
A left-to-right pipeline of 7 stages containing approximately 40 agents in total. Stage 1 of 7: FOUNDATION. It hands off a CaseFoundation payload to the next stage. Stage 2 of 7: DISCOVERY. It hands off a DiscoveryPlan payload to the next stage. Stage 3 of 7: MOTION PRACTICE. It hands off a MotionSet payload to the next stage. Stage 4 of 7: HEARING PREP. It hands off a HearingBrief payload to the next stage. Stage 5 of 7: DEPOSITION. It hands off a DepositionPlan payload to the next stage. Stage 6 of 7: EXPERTS. It hands off a ExpertReport payload to the next stage. Stage 7 of 7: FINAL STRATEGY. Each arrow between stages is a typed, schema-validated contract rather than free text.

How it holds together
On the providers
Each stage routes across Claude, Gemini, and OpenAI with automatic failover.
On cost
Shared case context is cached with a stable prefix and memoized per session rather than re-read per agent — roughly 60% of token spend.
The handoff contracts
Agents cannot pass prose to each other. Every stage boundary is a validated schema with explicit status enums and mandatory evidence citations, so disagreement fails at the seam instead of compounding downstream.
