Thoughtworks veterans stay wary of coding agents in production
The lesson is that 'it runs' and 'it is safe to run in production' are still far apart with agents, and guardrails — tests, contracts, architecture checks — matter more than raw code output. Engineering leads and platform teams evaluating agentic workflows should budget for harness-building and design feedback loops rather than measuring speed alone. The whiteboard-to-harness split offers a concrete template for how roles may shift, though Thoughtworks itself calls the story incomplete.
