What should a native agent harness handle beyond tool calling?
Glittering812 · reddit · 2026-10-23
A Reddit discussion on production agent harness design argues that once agents run for hours or days, the hard problems live outside the model: managing context/memory/state across long tasks, deciding whether retries/permissions/scheduling belong in the harness or a workflow engine, verifying task completion rather than trusting reports, and essential logging and risk controls before granting real tool access. The author focuses on the boundary between model reasoning and deterministic infrastructure: what belongs in an agent runtime built from scratch today.
