HN Show: Tool Generates Before/After Change-Preview Pages for Code Review
A developer built a skill that auto-generates a review page combining before/after screenshots, diagrams, annotated UI changes, code diffs, and AI-written rationale for reviewing AI agent output. The post showcases the built tool rather than describing an unmet need in detail.

Similar Problems
surfaced semanticallyReviewing Large AI-Generated Code Diffs Overwhelms Developers
Developers reviewing large code changes produced by coding agents face walls of unstructured file diffs that are hard to parse and give feedback on. Existing terminal-based review tools address pieces of this but lack a narrated, chaptered walkthrough that breaks a large change into a guided, commentable tour.
No Inline Source Verification in AI Outputs for High-Stakes Contexts
When using LLMs for research or analysis in domains where errors carry real consequences — legal, medical, financial — users cannot easily verify that cited sources actually support the AI's claims without manually cross-referencing original documents. This context-switching is slow and trust-eroding, but skipping it risks acting on fabricated or distorted information. The problem is structural: current LLM interfaces present conclusions without grounding evidence visible alongside the output.
PR review fragmented from project management workflow
Engineering teams context-switch between project management tools and GitHub for code review, breaking focus and slowing iteration. Reviewing diffs natively inside the issue tracker where tasks live reduces this friction.
Project Documentation and Showcase After Coding Is Tedious and Manual
Developers frequently find the post-coding phase — writing READMEs, taking screenshots, checking for security leaks, and adding license info — more time-consuming than the actual coding. This last-mile effort is poorly automated and often skipped, leaving projects undiscoverable and underrepresented. The post showcases a workflow to address this, but the underlying pain is widespread.
No-Code Workflow Platforms Lack Meaningful Version Control
No-code workflow platforms store configurations as JSON or YAML but lack meaningful version control and visual diffing. When workflows break after changes, teams cannot easily see what changed or roll back to a working state.
