SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Long, noisy pull requests with whitespace-only changes, import reorders, and moved-but-unchanged code make reviews slow and create messy history. This Skill helps you identify and minimize those unnecessary changes so reviewers can focus on substantive edits.

Core Features & Use Cases

Categorizes changed files as substantive, whitespace-only, import-reorder, or trivial to highlight diff bloat.
Produces JSON and human-readable summaries, per-file flags, and exit codes to integrate with CI or pre-push checks.
Use cases: pre-PR audits, branch comparisons, and automated checks to enforce minimal, focused commits.

Quick Start

Run the analyze-diff.py tool on your current branch to flag whitespace-only, import-reorder, and other non-substantive changes.

FAQPage Schema

How do I detect whitespace-only changes in a git diff before creating a pull request?▼

To detect whitespace-only changes in a git diff, you can run an analysis script that categorizes modified files and flags non-substantive edits. This highlights diff bloat to keep your pull request focused and reviewable.

What is diff bloat and how do I identify moved code and import reorders in git?▼

Diff bloat consists of non-substantive edits like whitespace changes, import reorders, and moved code that make reviews slow. Analyzing your git history identifies these trivial changes so you can minimize them before pushing.

Can I generate JSON output from a git diff analysis for CI pipelines?▼

Yes, you can generate JSON output and per-file flags from a git diff analysis to integrate with CI or pre-push checks. This produces structured categorizations and exit codes to automate branch comparisons and enforce minimal commits.

Does this git diff analysis require access to the full repository history?▼

Yes, analyzing git diffs to detect moved code and import reorders requires access to git repository history. This access allows the script to perform local branch comparisons and accurately categorize substantive versus trivial changes.

What is the best way to audit a local branch for trivial code changes before a code review?▼

The best way to audit a local branch for trivial code changes is to run a diff analysis script that flags whitespace-only and import-reorder edits. This pre-PR audit produces human-readable summaries to help reviewers focus on substantive logic.
