Agent builders should map task complexity before copying Claude Code-style harnesses

Agent builders are overusing Claude Code-style harnesses, says VibeCoderOfek
The thread argues that many teams copy a heavy Claude Code-style harness into every agent and then end up with systems that are too slow and expensive.
The core advice is to map the job first instead of defaulting to a full stack of memory, compaction, sub-agents, orchestration, planning, hooks, guardrails, and evals.
- A good agent architecture depends on two axes:
- Action complexity: how many tools, decisions, dependencies, and iterations the agent must coordinate.
- Context complexity: how much information must stay coherent across model calls.
- The author says a coding agent is high on both axes, so it may need the full stack.
- By contrast, low-context support agents often need very little of that machinery.
- The practical takeaway: build the minimum harness that matches the task, rather than treating one architecture as a universal default.
