Skills (8)

• ascendc-api-best-practices

  Verify and explain Ascend C API usage for arithmetic, reduction, data movement, transpose, UB buffers, precision conversion, pipeline synchronization, repeat limits, and host runtime calls. Use when implementing or debugging an Ascend C kernel, resolving alignment or overload errors, reviewing API c

• ascendc-code-review

  Review Ascend C Host, Tiling, Kernel, SIMT, build, and supporting Python changes for correctness, security, compatibility, and performance risks. Use for code snippets, local diffs, pull requests, operator implementations, or focused rule checks where findings must be evidence-based and tied to the

• ascendc-docs-search

  Locate authoritative, version-matched Ascend C and CANN API documentation, headers, implementation examples, compatibility notes, and source references. Use when answering API questions, checking overloads or SoC restrictions, finding operator examples, validating review claims, or resolving differe

• ascendc-env-check

  Inspect an Ascend development or runtime host for CANN environment variables, installed version metadata, toolkit and operator paths, diagnostic tools, and NPU visibility. Use for environment checks, npu-smi or asys diagnostics, CANN setup verification, missing-tool investigation, and read-only tria

• ascendc-npu-status

  Check and compactly monitor whether explicitly requested Ascend NPU devices are idle by reading a versioned env_list.json inventory and querying per-device process memory locally or over SSH. Use before NPU tests or benchmarks, when selecting free devices across hosts, or when a machine-readable res

• ascendc-operator-development

  Develop or migrate complete Ascend C operators across direct kernel launch and registered custom-operator workflows, including OpDef and inference, Host Tiling, Kernel contracts, ACLNN integration, build and package wiring, and staged validation. Use when creating a new operator, converting between

• ascendc-runtime-debug

  Diagnose Ascend C and CANN runtime failures using exact error messages, plog and device logs, launch and stream state, Tiling and kernel dispatch, installed operator packages, and bounded reproduction evidence. Use for ACLNN or ACL return codes, kernel-not-found or Tiling failures, vector or cube ex

• cann-env-setup

  Plan, install, configure, or repair a CANN development environment for Ascend hardware with explicit version and platform compatibility checks. Use when selecting CANN packages, preparing offline or repository-based installation, configuring environment scripts, resolving driver/toolkit/ops mismatch
