AI Cluster Pre-flight Check
Pre-flight check for GPU cluster nodes — 26 health checks covering GPU, PCIe, RDMA/IB, Docker, IOMMU, NUMA, firewall, and more
AI Cluster Pre-flight Check is a legitimate GPU cluster node health validation tool performing 26 read-only hardware/network diagnostics. No malicious behavior, credential harvesting, or covert data exfiltration found.

Safe to install
No blocking action needed. The eval in check_1_25 should be documented explicitly, and dmidecode/iptables root requirements should be stated in SKILL.md for transparency.

Severity Finding Location
Low
eval on user-supplied SWITCH_CLI_CMD not declared Doc Mismatch
check_1_25 uses eval to execute SWITCH_CLI_CMD directly from the environment. While this is user-supplied input (not injection), SKILL.md documents the SWITCH_* env vars as 'switch CLI command' without explicitly calling out the eval usage or potential for arbitrary command execution if the variable is set to unexpected values.
eval "$SWITCH_CLI_CMD"
→ Document in SKILL.md that SWITCH_CLI_CMD is executed via eval; recommend using SWITCH_HOST + SWITCH_USER for safer SSH-based switch access instead.
 lib/checks.sh:272
Low
Root privilege requirements not declared Doc Mismatch
Several checks invoke commands that typically require root (dmidecode, iptables, setpci, ibstat, perfquery, mlxlink). SKILL.md does not document that root or sudo access is needed for full coverage.
dmidecode -t bios 2>/dev/null | head -30
→ Add a 'Requirements' section noting that root privileges are needed for checks 1.14, 1.16, 1.19, 1.20, 1.21 to pass fully.

Security Positives

✓ No credential harvesting — does not access ~/.ssh, ~/.aws, .env, or iterate os.environ for secrets
✓ No data exfiltration — all output is diagnostic; JSON results printed to stdout for the calling agent
✓ No obfuscation — all shell scripts are plain text, no base64, no eval-of-encoded strings
✓ Docker pulls from official nvidia/cuda and rocm/rocm-terminal images — known-good sources
✓ Cross-node capabilities (SSH, ping) are explicitly declared in the check catalog and documentation
✓ Skippable failure classification is a thoughtful UX feature that reduces false positives
✓ No remote script execution (no curl|bash, wget|sh patterns)
✓ No supply chain risks — no external dependencies beyond bash, jq, and system tools
