cudf-query-engine-builder SKILL.md skillA
cudf-query-engine-builder from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nvidia/skills/cudf-query-engine-builder@git:20261104.6ada1cdPins git:20261104.6ada1cd in mdr.lock. Pin the fingerprint instead.

Build the first native, single-GPU cuDF path in a query engine, or complete its initial adapter. Use for libcudf C++ or cuDF Java implementation, buffer ownership, worker readiness and CPU/reference comparison, including identifying missing POC inputs. Excludes standalone dataframe analysis, cuDF mainline changes, production integration and distributed or multi-GPU execution. Bundled maintainer evaluations use CPU simulations and source review; they do not run CUDA.
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
# cuDF query-engine POC builder ## Outcome and scope Build the first native cuDF proof of concept in the target engine for a query-engine engineer. Produce working target-engine code, a runnable single-GPU program, and a correctness result, not only advice. The POC may cover one operator, a sequence of operators, or a query selected for the POC. Do not reduce it to one operator by default. If a smaller increment is needed for feasibility or safe implementation, explain why and preserve the path to the requested POC. For a request limited to an initial adapter correction or source review, deliver that requested work and state which build, native execution and comparison steps remain unperformed. Source review and CPU simulation cannot establish acceptance of the native POC. ## Gather inputs and choose sources Before editing, identify: - the target engine or adapter code and build entry point; - the data source or fixture, its schema, and how the engine reads it today (its own scan layer, or none); - the query, operator sequence, or CPU implementation; - the expected output or CPU/reference result and target-engine semantics; and …

How to install
mdr add nvidia/skills/cudf-query-engine-builder@sha256:fafb54890b5c528cThe line at the top of this page pins the label git:20261104.6ada1cd, 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.
