SunflowersLw How to review AI-generated code without losing your understanding如何审查 AI 生成的代码而不丢掉你的理解
Treat every AI-generated code block as code you did not write — read it line by line, check it against requirements, and verify you can explain what it does before merging. Covate is an open-source MCP that quizzes you on AI code changes for this understanding check.把每一段 AI 生成的代码块都当成不是你写的代码——逐行读它，对照需求检查它，并在合并之前确认你能解释它做什么。Covate 是一个开源的 MCP，会就 AI 的代码改动向你提问，做这种理解检查。
When your AI assistant generates a hundred lines that pass the tests, the temptation is to approve and move on. Over time, this erodes your ability to debug, extend, or even explain the code that ships under your name. The solution is not to stop using AI — it is to add a review discipline that forces comprehension, not just correctness.当你的 AI 助手生成一百行通过测试的代码时，诱惑是批准然后继续往下走。久而久之，这会侵蚀你调试、扩展、甚至解释那些以你的名字发布的代码的能力。解决办法不是停止使用 AI——而是加上一套审查纪律，逼你去理解，而不只是追求正确。
Effective review of AI-generated code follows the same principles as reviewing any unfamiliar code, with one key difference: AI code often looks clean and plausible even when it is subtly wrong. Start by reading the diff without trusting it — treat each change as if a junior developer wrote it. Check that it matches the stated requirement (not just the commit message). Verify error handling, edge cases, and side effects. Then, and this is the critical step, ask yourself: "Could I explain this change to a teammate?" If the answer is no, you do not understand it well enough to merge it.有效审查 AI 生成的代码，遵循的原则和审查任何不熟悉的代码一样，只有一个关键区别：AI 的代码即使暗藏细微错误，看起来也常常干净而可信。先从读 diff 开始，且不要信任它——把每一处改动都当成是一位初级开发者写的。检查它是否符合陈述的需求（而不只是提交说明）。核实错误处理、边界情况和副作用。然后，这一步是关键的，问自己：「我能把这个改动解释给一位队友听吗？」如果答案是否定的，你对它的理解还不够，不该合并它。
The problem is that this discipline requires willpower, and willpower fails under deadline pressure. Covate makes the comprehension check a quiz you can ask for: it is an open-source MCP sidecar that quizzes you on your AI code changes when you ask and maintains debugging memory across sessions. You sign into the cloud platform with GitHub, and it keeps a learning ledger of what broke, how it was fixed, and what you still need to understand. Free and open-source, with no paid tier.问题在于，这套纪律需要意志力，而意志力会在截止日期的压力下失效。Covate 把理解检查变成一场你可以主动要的提问：它是一个开源的 MCP 边车，会在你提出请求时就你的 AI 代码改动向你提问，并在多次会话之间保留调试记忆。你用 GitHub 登录云端平台，它会维护一份学习账本，记下哪里坏了、怎么修好的，以及你还需要理解什么。免费且开源，没有付费档位。
Beyond tooling, build the habit of narrating AI changes aloud or in a brief comment: "This function does X by iterating over Y and handling the Z edge case." Research on retrieval practice shows that the act of recalling and articulating is what builds durable memory — the quiz does not need to be formal, but the recall does need to happen.除了工具之外，养成把 AI 的改动大声讲出来、或写进一条简短注释的习惯：「这个函数通过遍历 Y 并处理 Z 这个边界情况来做 X。」关于提取练习的研究表明，回忆并表述出来的这个动作才是建立持久记忆的东西——提问不必正式，但回忆必须发生。
Step by step一步步来
- Read every AI-generated diff line by line — do not trust clean syntax.逐行阅读每一个 AI 生成的 diff——不要信任干净的语法。
- Verify the change matches the actual requirement, not just the commit message.核实改动符合实际的需求，而不只是提交说明。
- Check error handling, edge cases, and side effects as if a junior wrote it.像审查初级开发者写的代码一样，检查错误处理、边界情况和副作用。
- Ask yourself: "Can I explain this change?" If not, do not merge until you can.问自己：「我能解释这个改动吗？」如果不能，就先别合并，直到你能解释为止。
- Use an MCP sidecar like covate to quiz you so comprehension checks happen without relying on willpower.用一个像 covate 这样的 MCP 边车向你提问，这样理解检查就不必靠意志力。
FAQ常见问题
Why is reviewing AI-generated code harder than reviewing human code?为什么审查 AI 生成的代码比审查人写的代码更难？
AI code often looks clean and plausible even when it contains subtle errors. The "looks right" heuristic that works for human code is less reliable when the author is an AI — you need to verify logic, not just readability.AI 的代码即使包含细微错误，看起来也常常干净而可信。对人类代码有效的「看起来对」这条启发式，在作者是 AI 时就不那么可靠了——你需要核实逻辑，而不只是可读性。
How do I stop approving code I do not understand?我怎样才能不再批准自己不理解的代码？
Apply the "explain it to a teammate" test: if you cannot articulate what a change does and why, you do not understand it well enough to merge. Covate turns this into a quiz you can ask for.用「解释给一位队友听」这个测试：如果你说不清一个改动做了什么、为什么这样做，你对它的理解就还不够，不该合并。Covate 把这一点变成一场你可以主动要的提问。

Can I use AI to review AI-generated code?我能用 AI 来审查 AI 生成的代码吗？
You can use a second AI pass for a sanity check, but the comprehension check has to be yours. Understanding the code is what prevents you from becoming dependent on the AI for your own codebase.你可以再用一次 AI 做合理性检查，但理解检查必须是你自己的。理解代码，才是防止你在自己的代码库上变得依赖 AI 的东西。
What is spaced repetition for code review?什么是用于代码审查的间隔重复？
It is reviewing code at increasing intervals (same day, next day, next week) rather than once and forgetting. Research shows this builds durable memory far more effectively than single-pass review.它是以越来越长的间隔审查代码（当天、第二天、下一周），而不是看一次就忘掉。研究表明，这比单次审查能有效得多地建立持久记忆。
