SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Explains branch changes at the implementation level by providing a structured analysis of diffs with cited code excerpts and flow tracing.

Core Features & Use Cases

  • Provides a deterministic diff collection workflow: gather inputs, resolve paths, collect diff, and generate a report.
  • Produces a reproducible, code-backed analysis suitable for code reviews and design discussions.
  • Use Case: A developer wants to understand why a particular bug was introduced by examining exact changed lines and surrounding context.

Quick Start

Run the analyze-diff skill on a target branch or commit range and review the generated diff-navigator-report.md.

FAQPage Schema
How do I analyze a git diff to understand code changes between branches?

To analyze a git diff, you can generate a structured report that reads file statistics and contextual code excerpts between branches. This produces a reproducible, code-backed analysis suitable for understanding implementation-level changes and tracing potential bugs.

What is the best way to generate a code review report from a git branch diff?

The best way to generate a code review report is to use a deterministic workflow that collects diffs and resolves paths to output a structured markdown file. This reproducible analysis cites exact changed lines and surrounding context for design discussions.

How does diff analysis with code excerpts help trace introduced bugs?

Diff analysis with code excerpts helps trace bugs by examining exact changed lines and their surrounding context within the repository history. It provides implementation-level insights and flow tracing to pinpoint why and how a specific change altered behavior.

Do I need any external dependencies to analyze git diffs for audit trails?

No external dependencies are required to analyze git diffs for audit trails. The process relies on reading existing Git diffs, file statistics, and contextual code excerpts directly from your live repository history to produce the structured analysis.

Can I use branch diff analysis for understanding commit histories in live repositories?

Yes, you can use branch diff analysis for understanding commit histories in live repositories. It gathers inputs from a target branch or commit range and applies a deterministic collection workflow to generate a code-backed report of the changes.
