hyperpod-node-debugger

hyperpod-node-debugger is a skill for Claude Code from awslabs/agent-plugins. It costs 139 tokens per session (4,861 once invoked), scanned A, original, Apache-2.0.

A diagnostic guide for finding and fixing problems affecting one AWS SageMaker HyperPod cluster node. A node is an individual computer in the cluster, which may run on Kubernetes or the Slurm job scheduler.

In plain words
What is it for?
Use it when a specific node is unhealthy, unresponsive, stuck, marked down or drained, or needs to be considered for replacement.
Why use it?
It helps narrow down whether the problem comes from the node's network, accelerator hardware, storage, memory, scheduler state, or startup scripts. It keeps diagnostics read-only and presents state-changing commands for the customer to run.

About the project

awslabs/agent-plugins is a collection of plugins, skills, instructions, an MCP server, a hook, and a setting that guide AI coding agents in architecting, deploying, and operating software on Amazon Web Services. It is for developers using coding agents such as Claude Code, Codex, and Cursor with AWS projects. The catalogue entries are the repository's own agent workflows and supporting components.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hyperpod-node-debugger scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/check-efa-sg.sh, scripts/check-node-reachability.sh, scripts/check-vpc-config.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HyperPod Node Debugger

Operating policy. Run read-only diagnostics yourself. Never run a command that changes cluster, node, or workload state — present each one as a Suggested command (run this yourself) block and wait for the customer. Destructive order: investigate → reboot → replace (replace destroys root + secondary volumes; not supported on Slurm controller nodes). Never discard training state, logs, or caches on speculation.

IaC note (always include with mutation commands). When you suggest any command that changes cluster, VPC, SG, subnet, or EKS configuration (e.g. authorize-security-group-*, modify-vpc-attribute, update-cluster, kubectl label/cordon/drain, create namespace, set env daemonset), ask the customer first whether the cluster / VPC / SG is managed by Infrastructure-as-Code (CloudFormation, CDK, Terraform, Pulumi). If yes, tell them: "Apply this change in your IaC source first, then deploy through the pipeline — running the command directly will drift from your template and the next stack update may overwrite it." If they need to fix the issue immediately and the IaC change will follow, flag the drift explicitly so they remember to reconcile.

Read-only triage. scripts/triage-cluster.sh (and helpers check-efa-sg.sh, check-node-reachability.sh, check-vpc-config.sh) read state and print each issue as [FAIL] ... → references/node-diagnostics-detail.md § <section>. Catalog of customer-ticket patterns: references/node-issue-catalog.md.


Workflow

  1. Collect cluster name, region, suspect instance ID, exact error string from logs.
  2. Run scripts/triage-cluster.sh (add --node <INSTANCE-ID> to focus one node).
  3. For every [FAIL] / issue entry, Read the referenced section.
  4. Present: what script detected (copy the line verbatim), root cause, exact command(s) with instance/SG IDs filled in, blast radius (e.g. "reboots i-xxx", "wipes volumes on replacement"). For any command that mutates cluster/VPC/SG/EKS state, ask whether the affected resource is IaC-managed and surface the drift warning from the operating-policy note above.
  5. Wait for explicit customer approval. Destructive order: investigate → reboot → replace.
  6. Re-run triage to confirm. Iterate if not cleared.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
