dgx-spark-cli

Agent and CLI for operating an NVIDIA DGX Spark (Grace-Blackwell) workstation — device setup, health/monitoring, and local AI/ML workload management.

What you get

• An agent-first CLI cited from teken (afi-cli) — the runtime package has no third-party dependencies.
• A mesh identity — culture.yaml (suffix + backend) and the matching prompt file (CLAUDE.md for backend: claude).
• The canonical guildmaster skill kit (11 skills) under .claude/skills/, vendored cite-don't-import. See docs/skill-sources.md.
• A build + deploy baseline — pytest, lint, the agent-first rubric gate, and PyPI Trusted Publishing wired into GitHub Actions.

Quickstart

uv sync
uv run pytest -n auto                 # run the test suite
uv run dgx-spark-cli whoami  # identity from culture.yaml
uv run dgx-spark-cli learn   # self-teaching prompt (add --json)
uv run teken cli doctor . --strict    # the agent-first rubric gate CI runs

CLI

Verb	What it does
whoami	Report this agent's nick, version, backend, and model from culture.yaml.
learn	Print a structured self-teaching prompt.
explain <path>	Markdown docs for any noun/verb path.
overview	Read-only descriptive snapshot of the agent.
doctor	Check the agent-identity invariants (prompt-file-present, backend-consistency).
cli overview	Describe the CLI surface itself.

Machine scope (DGX Spark host telemetry)

The Spark is the system, so these read-only verbs sit at the top level:

Verb	What it does
status	Machine-wide scope, anomalies first — the headline.
memory	Unified RAM + swap (the GB10 shares one pool across CPU and GPU).
gpu	Blackwell GB10: utilization, temp, power, clocks, and GPU processes.
disk	Filesystem usage for real block devices (via /proc/mounts + statvfs).
thermal	SoC thermal zones and hwmon sensors (no lm-sensors needed).
containers	Running Docker containers and their health.
network	Interfaces, default route, and reachable addresses.
processes	Top processes by resident memory (via /proc).

They have zero runtime dependencies — kernel telemetry is read from /proc and /sys, while nvidia-smi, docker, and ip are shelled out and degrade gracefully (a missing tool reports available: false and still exits 0). doctor remains the health gate. Because the GB10 has no discrete VRAM, nvidia-smi reports aggregate GPU memory as [N/A]; gpu instead sums per-process compute-app memory so you can see how much of the shared pool the GPU holds.

Every command supports --json. Results go to stdout, errors/diagnostics to stderr (never mixed). Exit codes: 0 success, 1 user error, 2 environment error, 3+ reserved.

Monitoring (monitor) — AI-free webhook watchdog

monitor turns the collectors into a deterministic, always-on watchdog. It evaluates the same numbers against configurable thresholds and POSTs to a generic webhook when a catastrophe condition crosses — and again when it clears (edge-triggered, so a standing condition doesn't spam). No AI, no new dependencies (urllib does the POST).

dgx-spark-cli monitor config --init     # scaffold ~/.config/dgx-spark/monitor.json
export DGX_SPARK_WEBHOOK_URL=https://…  # or put webhook_url in the config
dgx-spark-cli monitor check             # dry run: what's firing right now
dgx-spark-cli monitor test              # POST a synthetic alert
dgx-spark-cli monitor install           # write the systemd --user unit
dgx-spark-cli monitor enable            # start it always-on (+ linger)
dgx-spark-cli monitor status            # service + currently firing alerts

Verb	What it does
monitor check	Evaluate thresholds now (no webhook, no state change).
monitor once	One cycle: evaluate, deliver transitions, update state.
monitor run	Foreground watch loop (the systemd ExecStart).
monitor test	POST a synthetic alert to verify the webhook.
monitor config [--init]	Show resolved config / write a scaffold.
monitor install|enable|disable|status|uninstall	Manage the systemd --user service.

Watches memory %, swap %, disk %, hottest sensor, GPU temp, load-per-core, I/O contention (iowait % + blocked processes), container health, and subsystem availability. Thresholds live in the config (null disables a check); webhook_format is generic (default), slack, or discord.

When monitor run starts (the systemd ExecStart), it POSTs a one-shot "started watching" liveness alert — so a watchdog that silently fails to come up is noticed by the absence of its heartbeat, not just the absence of an alert. A failed startup POST is logged, never fatal. Set notify_on_start: false in the config to disable it.

Make it your own

1. Rename the package spark/ and the dgx-spark-cli CLI/dist name throughout pyproject.toml, the package, tests/, and sonar-project.properties.
2. Edit culture.yaml with your suffix and backend.
3. Rewrite CLAUDE.md for your agent and run /init.
4. Re-vendor only the skills you need from guildmaster (see docs/skill-sources.md).

See CLAUDE.md for the full conventions (version-bump-every-PR, the cicd PR lane, deploy setup).
