Watch Any Folder. Spawn a Response. No Daemons. No Cron. Just Files.

Have you ever wanted to trigger real logic — a script, a webhook, a notification — when a file appears in a folder?

You could:

Write a daemon
Set up inotifywait or fswatch

Build a custom shell loop
Fight with permissions, sockets, or systemd

Have you ever wanted to trigger real logic — a script, a webhook, a notification — when a file appears in a folder?

You could:

  • Write a daemon
  • Set up inotifywait or fswatch
  • Build a custom shell loop
  • Fight with permissions, sockets, or systemd

But here’s a quieter way:

🧠 MatrixSwarm: A File-Driven Agent System

With MatrixSwarm, you drop a single JSON into the system — and the OS creates an agent that:

  • Lives inside a folder
  • Watches any directory you want
  • Reacts to changes by design
  • Logs actions directly to the Codex

No containers. No runtime. No “always-on” loop.

Just file events + single-purpose Python.

📁 Example Agent: File Watcher 


json
{
  "agent_name": "watcher-1",
  "permanent_id": "watcher-1",
  "delegated": [],
  "filesystem": {
    "folders": [
      { "name": "payload", "type": "d", "content": null }
    ],
    "files": {}
  }
}


🔁 Real Use Cases
Upload folder monitor

GitHub Actions trigger

Discord file drop responder

Email inbox reader

Remote camera frame detector




Fork it.
Or Fork U.
(The swarm is open. Bring tools or get logged.)
