Cursor vs Claude Code vs Codex

AI coding tools differ not only in model capability, but also in context management, task boundaries, code review flow, and execution environment.

Tool	Strength	Risk
Cursor	IDE 内迭代快	容易局部最优
Claude Code	长任务拆解强	成本和上下文管理要求高
Codex	仓库任务自动化	需要清晰任务描述

Recommendation

When a team adopts AI coding tools, start with test coverage, code review, documentation, and small refactors before delegating core architecture work.
