Harness Engineering

You need this when you're building agents that run for hours or days without supervision. It covers the control plane: which files the agent can edit versus which stay locked (like eval metrics), how to structure append-only logs so crashes don't lose work, when to gate on novelty checks, and where to draw the human approval line. The core insight is that feedback loops break down when agents can modify their own success criteria, so you separate editable surfaces from locked rubrics. If you're setting up research loops, PR-generating workflows, or anything that needs rollback and durable state, this gives you the checklist and file patterns to keep autonomy from drifting into chaos.
