k4sh is traditionally headless (no GUI). This plugin spawns a lightweight local web server (port 8080) that renders a real-time dashboard. You can watch order flows, plugin statuses, and custom charts without ever touching the terminal.
k4sh (kinetic shell) treats plugins as pure composable functions that speak stdin → stdout → stderr. No background daemons. No global state. k4sh plugins
#!/bin/bash
# k4sh-plugin: hello_world
# version: 1.0
# description: Demonstrates a simple command extension.
function k4sh_plugin_hello()
echo "[k4sh] Hello from custom plugin!"
echo "Arguments received: $*"

Even the best k4sh plugins can encounter problems. Here is a quick fix guide:
| Issue | Likely Cause | Solution |
|-------|--------------|----------|
| Plugin fails to load | Missing dependency | Run k4sh plugin deps <plugin_name> |
| High latency (>5ms) | Plugin blocking the event loop | Switch to async mode (plugin_config.async = true) |
| Memory leak | Bad plugin code | Monitor with k4sh plugin memusage and update the plugin |
| Conflicts between two plugins | Both hook the same event | Change load order in k4sh/config/plugin_order.toml |
