## What it is
McFly is a Rust-based CLI tool that replaces the default ctrl-r shell history search with an intelligent, context-aware search engine. It prioritizes command suggestions in real time using a small neural network and stores extended history metadata in a SQLite database.

## Use cases
- search shell history intelligently with ctrl-r
- find commands I ran in this directory before
- avoid re-running previously failed commands
- scrub sensitive commands from shell history
- track command exit status and timestamps
- get history suggestions based on recently executed commands

## When to choose
- you use Bash, Zsh, Fish, or PowerShell and want a smarter ctrl-r
- you want history search that considers working directory and command context
- you want a fast, safe Rust tool that keeps your normal history file intact

## When to avoid
- you need a tool with active maintenance and quick bug fixes
- you use a shell other than Bash, Zsh, Fish, or PowerShell
- you prefer simple plain-text history search without a database

## Facets
- artifact type: cli-tool
