Claude Code vs Cursor vs Copilot: An Honest Review After 40 Production Automations

说明与用途

Claude Code 在多文件推理和上下文感知编码方面表现出色，降低了开发时间和客户修订次数，但需要仔细配置和成本控制。

问题

Choosing the most effective AI coding assistant for production-grade finance and trading automations that span multiple files, require robust error handling, and maintain existing code conventions.

结果

Claude Code delivers superior multi-file reasoning, context-aware code, and question-asking capabilities, leading to faster development and higher client satisfaction. Cursor excels in speed for single-file edits, while Copilot remains cost-effective for boilerplate tasks.

工作流

• 1. Create a CLAUDE.md file at project root with conventions, library versions, broker API details, and testing rules.
• 2. Use Claude Code for planning new automations, large refactors, and legacy code understanding.
• 3. Use Cursor for rapid single-file edits and inline completions during active typing.
• 4. Use Copilot for boilerplate-heavy typing and cost-sensitive tasks.
• 5. Monitor token usage, set bounded budgets, and switch models based on task type.

I asked it to refactor a bank-reconciliation project that spans eleven modules and 2,300 lines — it traced every call site, flagged one circular import I'd never noticed, and proposed a clean split in a single turn.

If the first three fixes don't resolve an issue, it sometimes cycles — tries approach A, moves to B, comes back to A wrapped in a helper.
