Build and Own Your Agent Harness: Custom Setups Beat Out-of-the-Box Agents
JainAI29 · x · 2026-09-12
JainAI29 argues you should build and own your agent harness: very few people understand the magic behind customizing and optimizing one, yet even a minimal harness quickly yields better code, outputs, costs, and writing.
In follow-up discussion, the suggestion is to ground yourself in the underlying fundamentals and start from existing options like Pi's SDK rather than building everything from scratch. The debate also touches on whether a dedicated harness pays off at company scale versus purely as a learning exercise.
