Stage is a code review platform designed to help engineers understand AI-generated code. Your team is drowning in an endless backlog of PRs. Stage turns code review into a guided process and enables you to review changes faster than using GitHub. Congrats on the launch, Charles Pan and Dean Stratakos!

@StageReviewApp This is awesome! I have an honest question: why wouldn’t GitHub, or even Anthropic embed something like this in their models?

@StageReviewApp Congratulations @ceefryingpan and @DeanStratakos on the launch. Excited for you guyss!!!

@StageReviewApp the bottleneck was never writing the code, it's reviewing diffs you didn't type against a spec you did. i spend more time reading output than i ever did writing. does Stage let you pin the review to an intended spec, or is it still diff-by-diff with no source of truth?

@StageReviewApp Exactly. AI speeds up code generation, but without better review the bottleneck just moves downstream into PR backlog and merge risk.

@StageReviewApp the bar has fallen so low in software engineering that instead of making products to fix the slop we are building products to better understand it

@StageReviewApp This is cool but once again I have to say that this is just babysitting code you didn't write 😆Teach the LLM to read its own diffs first

dnu5 months ago

@StageReviewApp without prompt + tool trace per hunk, review turns into archaeology fast. half the pain isnt bad code, its not knowing which agent step made the weird choice

Nobody is writing 90% of their code using AI. Here's the uncomfortable truth: The real productivity gain from using AI to write code is closer to 10%, nowhere near the 90% people claim. Sundar Pichai said in 2024 that 30% of the new code at Google was AI-generated. However, he went on to admit, during Lex Friedman's podcast, that engineering velocity had only increased by about 10%. AI-generated code isn't free code. It still has to be reviewed, tested, and made production-ready. Optimizing a single step (code generation) doesn't boost output if bottlenecks shift elsewhere (code reviews). It doesn't matter how much code you generate if you can't keep up the review process. The solution: Automate as much as you can the review and verification of your code. I'm working with Sonar, who is sponsoring this post, and they will take care of the code quality and security analysis of your code: • They review over 300B lines of code every single day • They cover reliability, security, and maintainability for your code • You can integrate them into your CI/CD pipeline • You can install them in your IDE (I use their VSCode extension) • Support for more than 30 languages Here is a link so you can check them out:

AI can write more code than any team can review by hand, and a pull request can look fine while hiding a security issue or missing a requirement. In our new short course, AI Code Review, built in collaboration with Qodo and taught by Nnenna, you'll learn the practices that make AI code review effective: review before you open a pull request, give the reviewer full context about your codebase, and triage findings by risk. Then you'll build your own review agent, from a context engine that finds the right code to a team of specialized reviewers. Enroll for free:

You've got to get to a higher leverage point and reviewing only the code is not it. Start reviewing the system. I made a skill you can use to generate a system review in your PRs to make reviewing changes much faster and more fruitful.

Reminder: You can use Codex code review as part of your ChatGPT subscription 🙂 1. Head to 2. Connect your GitHub 3. Enable code review 4. Choose between review all PRs, just yours or trigger explicitly with "Codex magazine review this" To not spam you Codex will respond with 👍 unless it finds high priority items. You can use AGENTS.md to shape what a high priority item is.

Reviewing AI-generated code is the new bottleneck. Writing code was slow before. Now, in a few minutes, you can generate virtually unlimited lines of code using AI. But developers are now spending 70% of their time checking that code. That's the new bottleneck. I've been using Cline, and they have a feature that actually helps with this: You can click a button and have Cline generate an inline explanation for every single line of AI-generated code. Take a look at the attached video. What it does: 1. You can read the code and the explanation together 2. You don't lose context while reviewing code 3. You understand the "why" behind each change And here is the best part: It works on any git diff. You can use it to review PRs, understand commits from other people, or catch up on a codebase you haven't touched in a while.
