# Hello Brainfuck

A greeting tool written entirely in **Brainfuck** - the famously minimalist esoteric programming language created by Urban Müller in 1993.

## About Brainfuck

Brainfuck has only 8 commands:
- `>` - Move pointer right
- `<` - Move pointer left
- `+` - Increment cell
- `-` - Decrement cell
- `.` - Output cell as ASCII
- `,` - Input to cell
- `[` - Jump past `]` if cell is zero
- `]` - Jump back to `[` if cell is non-zero

Everything else (including comments) is ignored.

## How It Works

The program builds each ASCII character using multiplication loops. For example, to print `H` (ASCII 72):
```brainfuck
>+++++++[-<++++++++++>]<++.[-]
```
This creates 7 in a cell, multiplies by 10 (using a loop), adds 2, then prints.

## Usage

### CLI

```bash
enact run enact/hello-brainfuck
```

### MCP (for LLMs/Agents)

Call `enact__hello-brainfuck` with no arguments.

## Output

Returns JSON:
```json
{"message":"Hello from Brainfuck!"}
```

## Why?

Because we can. And because every tool registry deserves at least one Brainfuck program.
