Use this skill whenever the user is doing hands-on DOCA programming on a BlueField DPU or ConnectX NIC and needs the foundation primitives every per-library context rests on — walking the doca_ctx lifecycle, discovering doca_dev / doca_devinfo and gating on doca_*_cap_* before trusting a feature, wiring doca_mmap / doca_buf_inventory / doca_buf for zero-copy I/O across libraries, driving doca_pe for completions, or DOCA Log's two-tier (--sdk-log-level vs app-side) model. Trigger even when the…
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 Common ## Examples - **"Tasks submit but nothing completes."** — start at the progress engine and ctx lifecycle, not a per-library rewrite. - **"DOCA_ERROR_BAD_STATE from doca_ctx_start."** — walk the Common lifecycle order before blaming Flow or RDMA. ## Instructions Follow Loading order below. Open the tasks companion for configure / build / run. Open the capabilities companion for ctx / buf / pe / log. Do not open every companion file. **Where to start:** This skill is the **foundation every DOCA app loads first** — before doca-flow, doca-rdma, doca-eth, doca-comch, or any other higher-level library. Every `doca_<library>_*` context is built on top of `doca_ctx`, every device handle is a `doca_dev` discovered through `doca_devinfo`, every zero-copy buffer is a `doca_buf` from a `doca_buf_inventory` over a `doca_mmap`, every task completion drains through a `doca_pe`, and every log line emits through `doca_log`. Open the capabilities companion when the question is *what does Common express* on this install; open the tasks companion when the user wants to *do* something (configure / build / modify / run / test / debug). If the user has …

How to install
mdr add nvidia/skills/doca-common@sha256:0abe737e1326b2b7The 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.
