TOON Context Compression

Pipe any command output through toon to compress JSON and save ~40% tokens.

Usage

# API responses
curl -s "https://api.example.com/data" | toon

# JSON files  
cat data.json | toon

# Any command - safe on non-JSON (passes through unchanged)
some_command | toon

Install

# Copy script to PATH
cp scripts/toon ~/.local/bin/
chmod +x ~/.local/bin/toon

Requires: npx (Node.js)

Example

[{"id":1,"name":"Alice"},{"id":2,"name":"Bob"}]

→

[2]{id,name}:
  1,Alice
  2,Bob

When to Use

Always when reading JSON files into context
