Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Diagnose CoreWeave NCCL transport and RDMA configuration from supplied logs, Pod resources and ibstat output. Use when multi-node training is slow, NET/Socket appears, or checking whether InfiniBand and GPU Direct RDMA are engaged. Trigger with "coreweave slow training", "is RDMA working", "NCCL fell back to TCP", "GPUDirect RDMA", or "infiniband not used".

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'coreweave-fabric-diagnostics' ] || [ -L ~/.agents/skills/'coreweave-fabric-diagnostics' ]; then echo 'A skill folder named coreweave-fabric-diagnostics already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jeremylongshore/tons-of-skills-marketplace' "$d" && git -C "$d" checkout --quiet '8dc06f02eb00b7d8d1c0e69dfb3add2fd9500979' -- 'plugins/saas-packs/coreweave-pack/skills/coreweave-fabric-diagnostics' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/saas-packs/coreweave-pack/skills/coreweave-fabric-diagnostics' ~/.agents/skills/'coreweave-fabric-diagnostics' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'coreweave-fabric-diagnostics' ~/.claude/skills/'coreweave-fabric-diagnostics' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
