Add jsonskim

[rxzzh]

Hello Awesome-json Team,

I wrote a small tool to get the struct of a large json file, good for human and LLM understanding.

hope it will be merged into the awesome-json family!

Thanks for your review!

Adding jsonskim - a UNIX-style CLI tool for extracting JSON structure by collapsing arrays and truncating long strings.

Why jsonskim?

• Array Collapse: Retains only the first N elements of each array
• String Truncation: Automatically shortens long strings with length indicators
• LLM-Ready: Output optimized for AI context windows (ChatGPT, Claude, etc.)
• Single Binary: ~700KB static executable, zero dependencies
• MCP Support: Works as a Claude Desktop tool via Model Context Protocol

Example

Input (imagine millions of records):

{"users": [{"id": 1, "bio": "very long..."}, {"id": 2}, ...], "logs": [...]}

Output:

{"users": [{"id": 1, "bio": "very lo...<truncated>"}], "logs": [...]}
