This is a prompt I use often to improve readability of a module. With something like Claude custom slash commands you can map these to an alias for easy use.

Prompt:
Analyze this code in the context of the following rules and apply appropriate refactoring.

Summary:
The goal of these rules is to improve readability within a file. 
It is highly valuable to start at the top of the abstraction hierarchy

This is a short LLM prompt to have the tool read your git history and summarize what you did in the project. It's nice to have. With something like Claude custom slash commands you can map these to an alias for easy use.

// summarize-day.md
Read through my git commit history for today and summarize what I did in a file with the filename `${yyyy-mm-dd}_Summary.md`. 
Create a 'worklog' folder in the root of this project, and save the markdown there.

Clean Architecture Filtering Layer: Design Patterns and Implementation

Overview

This code sample demonstrates a complete filtering layer implementation that adheres to clean architecture principles. The system provides type-safe, configurable filtering for business entities while maintaining strict separation of concerns and dependency inversion.

Architecture Layers

Domain Layer (Innermost)

The domain layer contains pure business entities and value types with no external dependencies:

/**
 * Creates a typed key-value pair object to work around TypeScript issue #13948.
 * This function preserves the literal type of the key in the resulting object type.
 *
 * @see [source](https://github.com/microsoft/TypeScript/issues/13948#issuecomment-1333159066)
 *
 * @example
 * const obj = createTypedKeyValue('userId', 123);
 * // obj has type: { userId: number } with literal key preservation
 *

This script is a vetting tool designed to automate the process of running tests, retrying failures if necessary, and saving the results of each test cycle to a session-specific directory. Here's a summary of its functionality:

Key Features and Workflow:

1. Session Setup:

   • Creates a session-specific directory based on the current timestamp and Git branch name.
   • Ensures the base directory (vetting-results) exists and creates the session directory recursively.

2. User-Specified Test Parsing:

   • Parses command-line arguments to extract user-specified tests to run.

const logFolder = 'LogFolder'
const logFilePath = join(process.cwd(), logFolder, 'proxy.log')

// Ensure the log folder exists
if (!existsSync(logFolder)) {
