O'Reilly Radar: choose a coding harness by the control layer you need
Overview
O'Reilly Radar argues that developers should pick a coding harness by which layer of control they need, not by overall quality.
It says Claude Code gives control inside the run through instructions, skills, subagents and hooks. Codex offers separation through sandboxed, noninteractive runs. Pi exposes the agent loop itself, and DeepSeek's harness is built from composable plug-ins.
The article's recommendation is to match the harness to the layer where control is required. The report does not include benchmark results or measured performance comparisons between the four tools.
