Sglang Model Gateway
SGLang Model Gateway (`sgl-model-gateway`, formerly `sgl-router`) — Rust router fronting vLLM/SGLang inference workers on Kubernetes. Trigger on "sgl-model-gateway", "sgl-router", "sglang router", "smg", "amg", "model gateway", "inference gateway", "load balance vllm replicas", "fan out same model", "kubernetes vllm router", "cache-aware routing", "prefix_hash policy", "PD disaggregation router", "--worker-urls", "--service-discovery", "--enable-mesh", "smg_* metrics". Covers: first-class vLLM gRPC backend (`RuntimeType::Vllm`) plus HTTP transparent-proxy for vanilla vLLM; eight policies; air-gapped recipe (gateway ignores `HF_ENDPOINT`, mount tokenizer on PVC); K8s manifests with `model_id` labels + per-model RBAC; three HA mitigations (single+PDB / `sessionAffinity` / `--enable-mesh` CRDT sync); pitfalls (vLLM HTTP discovery registers empty labels, gRPC probes need numeric ports, `sgl_router_*` → `smg_*` rename Dec 2025).

From the source SKILL.md
Target audience: operators running vLLM and/or SGLang inference on Kubernetes, fronting workers with a router that does cache-aware load-balancing, optional prefill-decode disaggregation, and dynamic worker registration. Especially: hosting multiple replicas of the same model behind one address, in air-gapped clusters with local model mirrors (no live huggingface.co).
What this skill does
Sglang Model Gateway is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sglang-model-gateway/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Sglang Model Gateway Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 161,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Sglang Model Gateway skill?
Use Sglang Model Gateway when your Claude Code task falls under the Engineering category — specifically in the backend area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Sglang Model Gateway" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Sglang Model Gateway skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Sglang Model Gateway is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
