💡 This Skill includes references (resource) components.

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.
