The tool integrates with Claude Code, allowing developers to trigger AI-assisted reviews that flag issues like business logic errors and missing tests, while emphasizing that human reviewers retain final decision-making authority.", "body_md": "**AI coding tools have made writing code much faster.**\n\nBut we noticed a new bottleneck in our development workflow:\n\nCode review.\n\nWhen developers can create code faster, more PRs are opened. But the number of reviewers doesn't increase at the same speed.\n\nWhy review is the bottleneck\n\nThis is what we started seeing in our workflow:\n\nThe problem wasn't that our reviewers were slow.\n\nThere was simply too much code for humans to review manually.\n\nSo we started experimenting with AI for the first pass of PR review.\n\nWe built Open PR\n\nWe built Open PR, an open-source AI agent for reviewing GitHub pull requests.\n\nGitHub — TOMOSIA-VIETNAM/open-pr\n\nThe idea is simple:\n\nDeveloper → Pull Request → AI Review → Human Review → Merge\n\nAI handles the initial pass, while humans make the final decisions.\n\nWe're particularly interested in problems that go beyond formatting or simple code smells — things like business logic, unexpected side effects, missing test cases, and inconsistencies with the existing codebase.\n\nSetup with Claude Code\n\nFirst, make sure you have GitHub CLI installed and authenticated:\n\n```\ngh auth login\n```\n\nThen add the Open PR plugin marketplace and install the plugin:\n\n```\n/plugin marketplace add TOMOSIA-VIETNAM/open-pr\n/plugin install open-pr@open-pr\n```\n\nOnce installed, you can review a GitHub PR directly from Claude Code:\n\n```\n/open-pr:review <PR_URL>\n```\n\nFor example:\n\n```\n/open-pr:review https://github.com/your-org/your-repo/pull/123\n```\n\nClaude Code will analyze the PR and return review findings that you can inspect and discuss before merging.\n\nStill an experiment\n\nWe don't think AI code review is solved.\n\nAI can miss important issues, misunderstand business context, or produce false positives. That's why we're treating Open PR as an assistant for reviewers, not a replacement for them.\n\nWe're sharing it openly because we'd like to learn from other teams.\n\nHas AI made your PR review process the new bottleneck?\n\nIf you're experimenting with AI-assisted development, we'd love to hear what your workflow looks like.\n\nOpen PR on GitHub", "url": "https://wpnews.pro/news/we-built-an-open-tool-to-make-github-pr-reviews-less-of-a-bottleneck", "canonical_source": "https://dev.to/open_pr/we-built-an-open-tool-to-make-github-pr-reviews-less-of-a-bottleneck-157k", "published_at": "2026-09-04 08:18:33+00:00", "updated_at": "2026-09-04 08:23:47.587195+00:00", "lang": "en", "topics": ["developer-tools", "ai-agents", "ai-products"], "entities": ["TOMOSIA-VIETNAM", "Open PR", "GitHub", "Claude Code"], "alternates": {"html": "https://wpnews.pro/news/we-built-an-open-tool-to-make-github-pr-reviews-less-of-a-bottleneck", "markdown": "https://wpnews.pro/news/we-built-an-open-tool-to-make-github-pr-reviews-less-of-a-bottleneck.md", "text": "https://wpnews.pro/news/we-built-an-open-tool-to-make-github-pr-reviews-less-of-a-bottleneck.txt", "jsonld": "https://wpnews.pro/news/we-built-an-open-tool-to-make-github-pr-reviews-less-of-a-bottleneck.jsonld"}}
