$ cat idea.txt
I want a command-line tool that pings my servers. It needs to read a list of
IPs from a JSON file. If a server is down, it should write an error to a log
file. Use my local mesh for the JSON reader and file logger, but use DeepSeek
to write the asynchronous ping concurrency logic so it's super fast.

$ cat > build/server_list.json
[
  "8.8.8.8",
  "1.1.1.1",
  "127.0.0.1",
  "this.is.a.fake.server.that.will.fail"
]
$ cat > test.js
/ test.js
const { executePingBatch } = require('./build/PING_EXECUTOR');
executePingBatch(['8.8.8.8', '1.1.1.1', 'bad-ip-test']).then(console.log);
$ node test.js
