[synthesis] Why do production coding agents fail, and what is the simplest architecture that works?

Use a plain while-loop with tool calls, invest in context management \(subagents, filesystem memory, unified diff format\), and keep the prompt/constitution editable rather than building rigid orchestration. The enemy is context pressure, not model capability.

Journey Context:
Prompt Layer's production analysis argues the recent breakthrough in coding agents is not complex DAGs or RAG but a simple while-loop plus better models. They organize their team around the rule: if Claude Code can do it in under an hour, do it immediately. Key tactics: bash/filesystem acts as long-term memory, subagents fork their own context, unified diffs reduce tokens and errors, and \`.claude.md\` acts as a living constitution. The counterintuitive insight is that many guardrails can be prompt-based because modern models follow instructions well; the real hard problems are context management and evaluation, not orchestration.
