SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the difficulty of maintaining situational awareness during long-running development tasks by automatically synthesizing the delta between your current work and the main branch.

Core Features & Use Cases

  • Change Synthesis: Automatically aggregates diffs and commit history to provide a high-level overview of progress.
  • Risk Assessment: Identifies potential gaps or follow-up tasks based on the current state of the code.
  • Use Case: Use this before a stand-up meeting or a pull request to quickly generate a summary of what you have accomplished and what remains to be done.

Quick Start

Run the diff-analyze skill to generate a summary of your current branch changes compared to the origin main branch.

FAQPage Schema
How do I summarize my git branch progress against main?

Summarizing git branch progress against main requires analyzing differences and commit history between your current working branch and the origin main branch. This automatically aggregates diffs to provide a high-level overview of development progress.

What's the best way to track code changes before a pull request?

Tracking code changes before a pull request is best done by synthesizing the delta between your current work and the main branch. This approach identifies potential gaps or follow-up tasks based on the current state of the code.

Do I need a local git repository to analyze branch differences?

Yes, you need a local git repository to analyze branch differences. Specifically, the repository must have an initialized origin remote to perform branch comparisons and aggregate the commit history against the main branch.

Can I generate a stand-up meeting summary from my recent git commits?

Yes, you can generate a stand-up meeting summary from recent git commits by analyzing the differences between your current working branch and origin main. It synthesizes your diffs to quickly show what you have accomplished and what remains.

How does automated diff analysis identify remaining development tasks?

Automated diff analysis identifies remaining development tasks by assessing risks and finding potential gaps based on the current state of the code. It compares your working branch against the origin main to highlight what is left to be done.

Why does branch comparison fail without an initialized origin remote?

Branch comparison fails without an initialized origin remote because the analysis depends on fetching differences and commit history from the origin main branch. Without the remote configured, the tool cannot establish the baseline for your working branch.
