What problem does it solve?

Explains a confusing wall of git changes by turning a diff or PR into an easy, intent-grouped walkthrough that helps the user understand what changed, why it happened, and how it works.

Core Features & Use Cases

Intent-based grouping: Clusters diff hunks into 2–6 human-labeled groups like setup, feature, fix, refactor, config/deploy, and tests.
Guided What/Why/How walkthrough: Produces concise explanations per group with file/line anchors for the “how” part.
Diff-to-action summary: Ends with a single memorable takeaway and suggested next steps (including glossary, git story, and ship/lifecycle follow-ups when relevant).

Quick Start

Ask your agent: explain the diff for this pull request as grouped What/Why/How walkthroughs with file and line anchors, then end with one question asking which group to zoom into.

FAQPage Schema

How do I understand a large git diff or pull request without reading every line?▼

Understand a large git diff by clustering hunks into 2–6 intent-based groups like setup, feature, fix, refactor, config/deploy, and tests. This produces a concise What/Why/How walkthrough with file and line anchors, preventing overwhelming line-by-line dumping and speeding up comprehension.

What is the best way to explain what changed in a pull request for a code review?▼

The best way to explain pull request changes for a code review is generating an intent-grouped walkthrough that clarifies what changed, why it happened, and how it works. This method clusters diff hunks into labeled categories and provides file:line anchors for guided navigation.

Can I get a summary of git changes grouped by intent instead of file order?▼

Yes, you can get a summary of git changes grouped by intent. The process clusters diff hunks into 2–6 human-labeled groups such as feature, fix, or refactor, and ends with a single memorable takeaway and suggested next steps for ship or lifecycle follow-ups.

How do I walk through a git diff and see exactly which file and line numbers changed?▼

Walk through a git diff by generating a safe walkthrough that includes file:line anchors for the “how” part of the explanation. These anchors pinpoint exactly where changes occurred within the intent-grouped clusters, making navigation through the codebase direct.

Does this diff explanation approach work for understanding changes after large edit batches?▼

Yes, this diff explanation approach works for understanding changes after large edit batches. It applies when users need clarity after massive edits, transforming a confusing wall of git changes into an easy, intent-grouped walkthrough without overwhelming line-by-line dumping.
