dsh-top

A plugin for the DeepSeek Harness (DSH) web GUI: a system monitoring tool that shows live system stats in a floating, collapsible panel pinned to the top-right corner.

Features

• CPU — live utilisation (computed from /proc/stat deltas) + core count
• MEM — used / total with percentage bar
• DISK — used / total with percentage bar
• NETWORK — download / upload throughput (computed from /proc/net/dev byte deltas)
• Top 6 processes — PID, name, CPU%, MEM%
• Dark color-coded palette (cyan CPU, magenta RAM, yellow disk, blue/green network), monospace
• Draggable via the title bar, collapsible via the – / + button
• Transient monitor processes (ps, awk, head, …) are filtered out of the top-processes list

How it works

Part	File	What it does
Host half	lib/index.js	Registers GET /api/dsh-top-stats; reads CPU, memory, disk, network and top processes with read-only /proc + ps + df reads.
Browser half	lib/client.js	dsh.client web bundle; registers the panel into the frame-wide shell.overlay slot; polls every 2 s.
Composition	cordis.patch.yml	The dsh.bundle patch layer that inserts the loader entry.

Security

Because it is a system monitor, the host half reads host-wide process, CPU, memory and disk state. To do that it invokes the fixed read-only binaries cat, ps and df via execFileSync with a static argv array (never a shell string), so there is no shell-injection surface and no attacker-controlled input. No data leaves the host, no credentials are read, and every read is read-only.

dsh.so's static scanner flags the node:child_process import as "critical". That is a heuristic signal on the mere presence of process access — not a vulnerability. Process access is intrinsic to a monitoring tool; review the (small) source yourself: the commands are hard-coded, read-only, and argument-confined.

Install

# place this package somewhere, then link it into your web profile:
dsh plugin --profile web add .
# or wire it manually into the profile's bundles + link dependency

Then restart the web app and refresh the page — the panel appears at the top-right.
