A 20-minute AI audit detected a software bug that three senior developers had overlooked, demonstrating the potential of AI tools for code review. The article also covers other AI developments from the week, including updates on AI models, tools, and industry trends.

Linear argues that code review should be fast to maintain developer momentum and reduce context switching. The article highlights that slow reviews create bottlenecks, delay feedback, and hurt team productivity, advocating for quick, lightweight review cycles.

The article argues that code review should be fast to maintain developer productivity and team velocity. It advocates for small, focused pull requests and quick turnaround times to reduce context-switching and bottlenecks. The piece suggests that slow reviews hurt morale and delay value delivery.

Blue-Bear-Security released baloo-bear, an open-source code review agent designed to automate security reviews of code. The tool aims to help developers identify vulnerabilities and improve code quality through automated analysis.

Reckoning is a GitHub Feedback Companion tool designed to help developers manage and review feedback on the GitHub platform. The repository provides utilities for streamlining feedback workflows and improving collaboration.

The author argues that while AI tools can accelerate code writing, code review standards should remain high to prevent quality degradation. They express concern that many teams are lowering review bars and shipping poor-quality "AI slop," leading to record-high bug counts across companies.

A junior software developer describes frustration with coworkers producing low-quality code that passes code review with only cosmetic changes, leading to poor maintainability and cascading defects. The developer seeks advice on how to address the situation after nine months of experience with the codebase.

A review of 128 YC-backed dev tools companies found that only two—Mergify and Graphite—block unchecked code merges by default, despite standards like branch protection being well-established. Most companies in the sample do not enforce merge checks, highlighting a widespread gap between recommended practices and actual adoption in developer tooling.

A software engineer asks how to handle non-technical colleagues using AI tools (vibe-coding) to independently build features and then requesting help reviewing and submitting the code. While seeing a working prototype can clarify what they want, the engineer worries this trend could degrade their role into cleaning up poorly written AI-generated code.

A developer asks whether paying $2 per bug-fix pull request is too high, noting that most of the 20-30 applicants are bots or agents and only 2-3 actually complete the work. Even lowering the reward to $0.39 attracts similar behavior. The developer struggles to filter out low-quality applicants and must check for malware in submitted PRs.

The article explores how cognitive load affects code reviews and offers strategies to improve review quality by reducing mental strain. It suggests techniques like reviewing smaller chunks of code, using checklists, and focusing on specific aspects per review session to make the process more effective and less exhausting for developers.

The article discusses ContextLévy, a small tool built to act as a PR guardrail against token bloat by flagging excessively large context windows in code changes. The author presents it to the community, questioning whether the tool is worth maintaining long-term.

Panorama is a code review tool that aims to speed up the review process, as shown on Show HN.

The article argues that the primary purpose of code review is not finding bugs, but rather sharing knowledge, improving design, and maintaining code quality standards. Code reviews serve as a communication and learning tool that helps build shared understanding and ownership across the team.

The article explains that reviewing AI-generated code is uniquely difficult because AI produces plausible-looking but subtly incorrect code, and humans tend to trust machine output, leading to overlooked bugs.

Mainline is a CLI tool that stores developer intent in Git via hooks, allowing coding agents to record rationale, trade-offs, and risks before and after edits. It aims to reduce rework by making historical intents and decisions visible before code review, and can export a static Hub for sharing.

The article critiques React's `dangerouslySetInnerHTML` prop name as an inconsistent security measure, arguing that developers become desensitized to such warnings over time, which reduces their effectiveness. The author suggests that security-relevant APIs should be fundamentally different in form, not just in name, to truly prevent unsafe usage.

Panorama is a tool designed to help developers review code more efficiently by providing a faster, streamlined interface for code review workflows.

The article argues that pull requests (PRs) introduce unnecessary delays and friction in software development, advocating for trunk-based development with short-lived branches and direct commits to main instead, claiming this approach improves team velocity and reduces code review bottlenecks.

The Thermo-Nuclear Code Quality Review skill from the Cursor Team Kit enforces an extremely rigorous code-review process, requiring 20+ comments per review, mandatory restructuring for nested loops or large functions, and immediate rejection of any code failing to meet its strict quality thresholds.

The article discusses how AI coding agents are reshaping software development by 2026, shifting the focus from manual code writing to skills like prompt engineering, code review, and system architecture. Developers are expected to adapt by mastering AI tooling oversight and higher-level problem-solving rather than routine coding tasks.

Patchmark is a new Language Server Protocol (LSP) tool for reviewing code diffs inside a text editor. It simplifies manipulating diffs, quoting text, removing hunks, and jumping to definitions without requiring special support for the language under review. The creator built it to address the cumbersome workflow of reviewing changes in code harnesses, markdown documents, and PRs.

A Hacker News user asks whether anyone is successfully using "vibe coding" tools like OmO or Ralph loops in a professional setting. They report that the workflow produces large diffs that are hard to trace back to specific prompts or decisions, and are seeking advice on keeping AI-generated code reviewable and traceable in a normal company codebase.

A developer built a Python/SQLite prototype to create a graph that captures the reasoning behind AI-generated code, aiming to make AI-assisted development easier to review later.

FKS2G is a tool that uses LLM-backed metrics to help developers decide how closely to review code changes, aiming to prioritize review effort based on the assessed impact or risk of each change.

Mitchell Hashimoto discusses why PR diff speed matters for developer productivity, emphasizing that slow diff rendering can significantly disrupt workflow and context switching during code review.

Starting June 1, 2025, GitHub Copilot code review runs will count toward a user's monthly included Copilot minutes on GitHub. This change affects Copilot Individual, Business, and Enterprise plans, where automated code review checks will now deduct from the plan's included compute minutes, rather than being free.

A group has published forensic intelligence reports analyzing 20 open-source codebases, examining their security, development practices, and potential risks. The reports aim to provide transparency and insight into the health and trustworthiness of widely used open-source projects.

Traditional small pull request rules are becoming obsolete with AI-assisted development, as AI generates larger code blocks. The author argues code review should focus on logical correctness and design intent rather than arbitrary size limits.

Haystack replaces GitHub's PR review system with a triage queue that sorts pull requests into three buckets—safe to merge, needs fixes, or needs human review—by analyzing diffs, codebase context, and coding-agent conversations. It aims to help teams manage the surge in PRs caused by AI coding agents, focusing human attention on reviews that can meaningfully change outcomes.
