anthropic just dropped a new tool called "the three-agent harness" that splits up planning, generation, and evaluation in long-running full-stack ai projects. it's all about making those multi-hour coding sessions smoother with structured steps.
i'm curious to see how this works out compared to other tools on the market right now! anyone tried something similar? what do you think makes a good workflow for extended ai development sprints?
_ i just realized we could call these "planner, coderbot & qa" agents instead of planning/generation/evaluation - that's more fun and relatable
