SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Most developers ship code and move on. But the fastest way to grow is to pause and reflect: what principle did I just apply? What trade-off did I make? What would I do differently?

This skill analyzes recent git history and surfaces the engineering lesson embedded in the work you just did.

Core Features & Use Cases

Git-history-driven — Analyzes commit history to surface actionable engineering takeaways.
Principle-grounded — Maps observations to named SE principles (from se-principles.md) and anti-patterns.
Conversation-ready outputs — Produces structured lessons ready for review and sharing.

Quick Start

Summarize the most actionable engineering lesson from my latest commits.

FAQPage Schema

How do I extract software engineering lessons from git commit history?▼

To extract lessons from git commit history, analyze recent diffs and commit messages to identify applied principles and anti-patterns. The skill reads recent changes and maps them to named engineering principles, outputting structured takeaways with evidence references.

What is the best way to map code refactoring changes to software engineering principles?▼

Mapping code refactoring changes to software engineering principles involves analyzing git diffs against an established principles reference. This skill compares your recent commits against se-principles.md and anti-patterns to surface the exact trade-offs made.

How many commits does the lesson extraction analyze from my current branch?▼

The lesson extraction analyzes the last five commits when operating on the main branch. If you are working on a feature branch, it reads the entire branch history to capture the full context of your feature work, debugging, or refactoring.

Can I generate a code review summary from recent git diff changes?▼

You can generate a code review summary from recent git diff changes by reading commit messages and change context. This skill processes your recent git history to produce conversation-ready, structured lessons grounded in software engineering principles.

Does this lesson extraction tool work with feature branches and main branch history?▼

Yes, the lesson extraction tool works with both feature branches and main branch history. It automatically detects your current git branch, analyzing the last five commits on main or the entire commit history when on a feature branch.

Why should I review anti-patterns and engineering principles after committing code?▼

Reviewing anti-patterns and engineering principles after committing code surfaces actionable takeaways from your recent work. This reflection process identifies applied trade-offs and maps findings to named principles, accelerating developer growth through grounded lessons.
