onboard-arch-precheck SKILL.md skillA
onboard-arch-precheck from hw-native-sys/simpler is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hw-native-sys/simpler/onboard-arch-precheck@git:20261027.6ad2778Pins git:20261027.6ad2778 in mdr.lock. Pin the fingerprint instead.

Detect the host's actual Ascend silicon and refuse mismatched `--platform` onboard hardware test invocations BEFORE any device is locked. MUST invoke this skill before running pytest or task-submit commands that use `--platform a2a3` or `--platform a5` (onboard only — sim variants pass through). Use when invoking onboard hardware tests, repro'ing flaky-test reports, or wrapping pytest in task-submit. Skip for `--platform a2a3sim` / `--platform a5sim` (silicon-agnostic).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Onboard Arch Precheck Gate to prevent running wrong-arch onboard tests on a dev box. CI already handles this (each onboard runner is labeled with its arch and only gets matching jobs). Local hardware work bypasses that protection — this skill restores it. ## Why this exists (DO NOT STRIP — non-obvious failure-mode context) This repo supports two onboard arches: - **`a2a3`** — Ascend 910 family (`Ascend910B*` = Atlas A2 silicon; `Ascend910_93*` = Atlas A3 silicon; both build via `dav-c220` and share `src/a2a3/`) - **`a5`** — different silicon (`Ascend950*` family, builds via `dav-c310`, `src/a5/`) A given dev box has ONE of them. **Running tests built for the wrong arch produces error cascades that look like genuine refactor bugs but aren't.** Typical signatures: | Error code | Surface | Meaning when arch-mismatched | | ---------- | ------- | ---------------------------- | | **507018** (`ACL_ERROR_RT_AICPU_EXCEPTION`) | `aclrtSynchronizeStreamWithTimeout` | AICPU kernel built against the wrong silicon contract faults at runtime; host sees a timeout / aicpu exception. | …

How to install
mdr add hw-native-sys/simpler/onboard-arch-precheck@sha256:a47f2a6e1962696aThe line at the top of this page pins the label git:20261027.6ad2778, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
