Spark Control Center — DevOps skill for Claude Code

DevOps community

Web control portal for a DGX Spark (GB10): GPU/thermal tuning verified against the machine's real state, AI app and skills configuration (ComfyUI, opencode, Claude Code), Docker containers and in-brow.

Spark Control Center is a web control portal for a DGX Spark workstation (GB10 chip): tune the machine, configure the AI apps running on it, and manage its Docker containers, all from the browser.

Features

The sidebar has four sections:

GB10 — the home view, labelled dynamically with the detected machine name. GPU and thermal tuning:
- Settings: GPU clock cap, persistence mode, swap, vm.swappiness, thermal monitor
- A switch never lies: every desired setting is compared against what the machine actually reports, with an explicit per-setting state (ok, pending, failed, skipped, diverged, unverified, unset) — some GB10 firmwares silently ignore nvidia-smi -lgc, and a UI that just echoed the request back would be lying
- Only what you set: settings the user never touched are not persisted
- Unprivileged container: it only writes a desired-state JSON that a root systemd oneshot validates against a strict allow-list and applies (details under "GB10 tuning" below)
Apps — reads and surgically edits the configuration of the AI tools installed on the host:
- ComfyUI: the command-line flags in its compose.yaml, and its user scripts
- opencode (opencode.json): default model, limit.context, compaction, skill paths/urls
- Claude Code: settings files, plugins, MCP servers, hooks — read-only except a short whitelist of harmless keys
- Edit pipeline: preview → line diff → warnings → explicit confirmation → atom
