pva-debug
Diagnose and narrowly repair one reproduced NVIDIA PVA operator failure. Use from OpGen or manually for compile, link, cuPVA lifecycle, dataflow, DMA, numerical, EMU-versus-hardware, runtime, or performance failures. Preserve the original evidence and return the repaired source to the caller for a fresh Build-Test.

What this skill does
<!-- SPDX-FileCopyrightText: Copyright (c) 2026 NVIDIA CORPORATION & AFFILIATES. All rights reserved. --> Debug a PVA operator Find one demonstrated cause. Make the smallest safe repair. Do not declare the complete operator passed. Resolve paths SKILLROOT is the absolute directory containing this skill's SKILL.md, after resolving symlinks. Bundled files are relative to that directory. Resolve supplied relative paths against the invocation directory before changing directories. Reuse OpGen's WORKDIR for its reports. For a direct call, use the supplied absolute report path, or resolve the caller's report work directory as WORKDIR. Get the inputs Require: A Doctor report that covers the failed capability. Absolute source and artifact paths, plus a report path or work directory. Caller identity: OpGen or a user with the same complete failure evidence. Failed stage, exact command, return code, full log, and source identity. Smallest known failing input, expected result, and tolerance. SDK version, PVA generation, compiler backend, build mode, and target identity when relevant. EMU and hardware results that already exist. One-based attempt number and maximum attempts for an OpGen call. Return BLOCKED before a source change when required evidence is absent or the attempt number is greater than the maximum. Load the technical basis Require Doctor's public-reference-corpus check to be PASS. Set SDKREFERENCES to the report's absolute sdkreferenceroot. Require a readable index.md and reference-lock.json, a lock SHA-256 matching the report's sdkreferencelocksha256, and the reported SDK version matching this task. If these fields are absent or no longer match, return BLOCKED and request a fresh Doctor report. Do not fall back to an installed package or CWD path. Read the pva-debug route in $SDKREFERENCES/index.md. Before reading Markdown, check its SHA-256 against the lock outputs entry; return BLOCKED on a mismatch. Resolve links relative to each generated file. …
