doca-rdma from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

RDMA data movement on NVIDIA BlueField/ConnectX NICs (RoCE/InfiniBand) with DOCA RDMA, instead of hand-written libibverbs/rdma_cm. Use when the user moves data between processes or hosts over the NIC, or hits "one-sided read returns permission denied", "completions never arrive after submit", "connection callback never fires", atomic compare-and-swap over RoCE, or DOCA_ERROR_FULL on the send queue under burst, even without naming DOCA RDMA. Covers bringing up an RDMA context on a doca_dev…
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
# DOCA RDMA ## Examples - **"Completions never arrive after submit."** — stay on the DOCA RDMA task and progress-engine path. Do not rewrite it as raw verbs. - **"One-sided read returns permission denied."** — check mmap + RDMA permissions and `doca_rdma_cap_*` before changing the task type. ## Instructions Follow Loading order below. Open the tasks companion for configure / build / run. Open the capabilities companion for the task taxonomy and safety policy. Do not open every companion file. ## Non-negotiable: the deliverable uses DOCA RDMA, not raw verbs When this skill is in scope, the user is asking for **DOCA RDMA**. The program you produce **must link `libdoca_rdma` and call the `doca_rdma_*` API** (directly in C/C++, or through a thin FFI/cgo shim from another language). Do **NOT** implement the request with raw `libibverbs` / `librdmacm` / RDMA-CM and call it done. Those move bytes but completely bypass DOCA — which defeats the entire purpose of using this library, loses the DOCA programming model (progress engine, task/ event lifecycle, capability discovery, portability across BlueField/ ConnectX generations), and is the single most common failure mode. …

How to install
mdr add nvidia/skills/doca-rdma@sha256:cce78dadd2101570The line at the top of this page pins the label git:20261028.3d06e7e, 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.
