model-pr-history-knowledgeUse when an SGLang, vLLM, TensorRT-LLM, or TokenSpeed serving/model optimization task needs prior model-family PR evidence. Query and read the PR-driven history docs under model-pr-optimization-history before choosing source paths, fast paths, kernel/fusion ideas, regression risks, or validation lan
llm-pipeline-analysisInspect LLM torch profiler traces at forward-pass, layer, and kernel level. Use when you need layer timings, anchor-kernel boundaries, representative kernel flows, or Perfetto time ranges.
llm-serving-auto-benchmarkFramework-independent LLM serving benchmark skill for comparing SGLang, vLLM, TensorRT-LLM, TokenSpeed, or another serving framework. Use when a user wants to find the best deployment command for one model across multiple serving frameworks under the same workload, GPU budget, and latency SLA.
llm-serving-capacity-plannerParse SGLang/vLLM startup logs to explain GPU memory use and request capacity. Use for KV cache budget, mem-fraction-static comparisons, OOM triage, and max-concurrency estimates.
llm-torch-profiler-analysisAnalyze existing Torch Profiler Chrome traces or capture from SGLang, vLLM, TensorRT-LLM and TokenSpeed servers. Return kernel attribution, overlap opportunities and fusion patterns; use for model dispatch, CUDA Graph gaps, stream contention or exposed kernel tails. Includes existing SGLang Omni tra
model-architecture-diagramReturn public original model architecture diagrams for user-specified LLM, VLM, MoE, diffusion, OCR, and SGLang/sgl-cookbook model families. Use when the user asks for a model structure chart, architecture diagram, or rendered image link for a specific model such as DeepSeek, GLM, Qwen, Kimi, MiniMa
model-compute-simulationBuild an operator-level compute template for an LLM and estimate FLOPs/MFU for a serving shape. Use when you need tensor shapes, per-op FLOPs, kernel-to-op MFU mapping, or parallelism what-if analysis.
sglang-model-day0-supportBuild or audit an evidence-driven SGLang Day-0 support program for a new LLM, VLM, MoE, hybrid-attention, or speculative-decoding model. Use when Codex needs to map a model architecture into SGLang runtime work, design a public support PR DAG, create validation and release gates, sanitize private de
sglang-explainer-videoTurn an SGLang PR (number or URL) or a technical article (Markdown path) into a Chinese explainer video that fully explains every algorithm and code change (length follows the material, no time cap) — natural edge-tts narration, word-synced bilingual 中文/English captions, the orange "SGLang PR 讲解 / S
sglang-prod-incident-triageReplay-first debug flow for SGLang serving problems. Use when a live or recent server shows health-check failures, latency or throughput regressions, queue growth, timeouts, distributed stalls, crash dumps, wrong outputs after deploys, or PD/EP/HiCache issues, and the job is to turn the problem into
torch-profiler-layer-trackAdd verified layer-number guides and compact GPU display lanes to an existing Torch Profiler Chrome JSON trace. Use for L0/L1/... navigation or traces with hundreds of CUDA Graph stream rows. Changes visualization, not runtime streams.
