End-to-end ONNX PTQ workflow for AMD Quark — for `.onnx` input models (with optional sibling `.onnx_data` external-weights file). Use when the user wants a complete ONNX-to-ONNX pipeline: model intake, quantization planning, calibration-script generation, manifest, and confirmed execution. Trigger for "quantize my .onnx", "run ONNX PTQ end to end", "full ONNX quantization pipeline", "quantize yolov8/resnet50/yolo_nas with XINT8/A8W8/BFP16/MXFP*", "weights-only INT4 for my .onnx LLM", or any request that spans more than one ONNX PTQ step. Not for HuggingFace / safetensors / PyTorch input models — use quark-torch-ptq instead.

quark-env-preflight

amd/Quark

Collect and normalize environment facts (OS, Python, GPU, CUDA/ROCm, container state) before Quark installation or PTQ planning. Use this skill whenever a downstream skill needs confirmed hardware and toolchain facts, when the user mentions their setup, when you need to decide between CUDA/ROCm/CPU install paths, or when any accelerator-related assumption is unconfirmed. Also trigger when the user says things like "check my environment", "what GPU do I have", "is my setup ready for Quark", or before any install/quantization step where hardware facts are missing.

quark-workspace-validate

amd/Quark

Validate workspace shape, model paths, output directories, and repo structure before downstream Quark skills proceed. Use this skill whenever a skill needs confirmed file paths, when the user provides a model path or output directory, when you need to distinguish a local model from a HuggingFace ID, or when any path assumption is unverified. Also trigger for "where should I put outputs", "is my model path right", or before model-intake/export steps.

quark-onnx-debug

amd/Quark

Diagnose failed Quark ONNX installation, calibration, quantization, custom-op compilation, or export attempts. Use when the user reports an error, stack trace, invalid artifact, missing dependency, ORT execution-provider mismatch, silent CPU fallback, OOM during calibration, custom-op load failure (BFPQuantizeDequantize / MXQuantizeDequantize / Extended*), or unexpected quantization results from the ONNX flow. Trigger for "Quark ONNX error", "onnxruntime error", "quantize_static failed", "calibration crashed", "CUDAExecutionProvider not available", "ROCMExecutionProvider not available", "custom op library load failed", "model.onnx larger than 2GB", "external data not found", "AdaRound diverged", "GPTQ ONNX failed", "QuaRot failed", "NPU power-of-2 scale", any Python traceback mentioning quark.onnx / onnxruntime / onnx, or when the user pastes an error message related to Quark ONNX workflows.

quark-onnx-install

amd/Quark

Install or verify the correct ONNX Runtime build (and the `onnx` package) for a user's accelerator backend before Quark's ONNX-to-ONNX flow. Use when the user needs ONNX Runtime set up, reports onnxruntime version conflicts, CPU vs GPU variant mix-ups (only one variant of `onnxruntime*` may be installed at a time), missing CUDA/ROCm execution providers, or when `import onnxruntime` / `import onnx` fails. Trigger for "install onnxruntime", "pip install onnxruntime", "set up onnxruntime for ROCm", "set up onnxruntime for CUDA", "onnxruntime-gpu vs onnxruntime", "onnx version mismatch", "CPU-only onnxruntime installed", "ORT providers list missing CUDAExecutionProvider/ROCMExecutionProvider", or any request to get the correct ONNX Runtime build running. Also trigger when `quark-install` reports that ONNX Runtime is missing or mismatched before proceeding with the ONNX flow.

quark-onnx-model-intake

amd/Quark

Inspect a target ONNX model and prepare metadata for Quark ONNX PTQ planning. Use when the user needs `.onnx` path validation, opset / IR version detection, input/output shape and dtype discovery, op-type histogram, quantizable-op counting, deployment-target compatibility checks (CPU / CUDA / ROCm / AMD NPU CNN / AMD NPU Transformer), or risk assessment before planning PTQ. Trigger for "analyze my ONNX model", "check this onnx model", "what opset is this", "can Quark quantize this .onnx", "is my model NPU-compatible", "does my model already have QDQ", "is my model larger than 2 GB", or when any ONNX quantization step needs model facts that are missing.

quark-onnx-quant-plan

amd/Quark

Build a Quark ONNX PTQ quantization plan from `model_analysis.json` and user intent. Use when the user needs preset selection (XINT8 / A8W8 / A16W8 / BF16 / BFP16 / MX* / MXFP* …), calibration method choice (MinMax / Entropy / Percentile / Distribution / NonOverflow / MinMSE / LayerWisePercentile), algorithm selection (CLE / AdaRound / AdaQuant / BiasCorrection / AutoMixprecision), deployment-target gating (CPU / CUDA / ROCm / AMD NPU CNN / AMD NPU Transformer), op-type include/exclude lists, weights-only INT4 (MatMulNBits) decisions, dynamic vs static quantization, or a draft `quant_plan.json`. Trigger for "what preset should I use for my ONNX model", "choose XINT8 vs A8W8", "plan ONNX PTQ", "INT4 "BFP16 / MXFP4 for my model", "calibration method for Ryzen AI", "should I use AdaRound or AdaQuant", "SmoothQuant alpha", or when the user has a model analysis and needs to decide how to quantize an ONNX model.
