A technical walkthrough of creating reliable, scalable AI harnesses to execute complex, multi-stage workflows (e.g., contract review), covering architecture, delegation, validation, and cost/control trade-offs.
– Demo of a contract-review harness with sub-agents, virtual file system, and state management.
– Harness patterns: deterministic rails, parallel sub-agents, memory and context strategies.
– Focus on reliability metrics, validation loops, model selection, and cost optimisation.
Quotes:
The march of nines: each extra nine takes comparable engineering effort.
Agentic workflows compound failure: a 10-step flow at 90% per step yields ~6 daily failures.
Put AI on deterministic rails — Stripe merged 1,300 pull requests weekly by validating changes against tests.
