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

Use this skill when the user is doing hands-on host-side DOCA PCC work to load a CUSTOM Programmable Congestion Control algorithm onto a BlueField DPU — creating per-port `doca_pcc` contexts, loading a `dpacc`-compiled `doca_pcc_app` onto the `doca_dev` for the RoCE-bearing port, parameterizing it, walking triple-axis capability discovery (DOCA cap-query + DPA-capable BlueField + firmware custom-PCC slot enabled), or debugging `DOCA_ERROR_*` from `doca_pcc_*`. Trigger even without explicit…
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 PCC ## Examples - **"Loading my own congestion control onto a BF port."** — this is in scope. Stay on host-side `doca_pcc` + a DPACC-built `doca_pcc_app`; do not rewrite the algorithm body here. - **"DOCA_ERROR_NOT_PERMITTED on algorithm load."** — check the firmware custom-PCC slot and DPA exposure before changing the load call. ## Instructions Follow Loading order below. Open the tasks companion for configure / load / debug. Open the capabilities companion for the triple-axis cap query. Do not open every companion file. **Where to start:** This skill assumes DOCA is already installed, the user's BlueField has a DPA processor that the host can see through DOCA, the BlueField firmware has the custom-PCC slot enabled, and the user is doing **hands-on custom PCC work from the host side** — i.e. using `doca-pcc` to load a DPA-side congestion control algorithm onto the BlueField, attach it to a port handling RDMA / RoCE traffic, and parameterize it from the host. Open the tasks companion if the user wants to *do* something (configure / build / modify / run / test / debug); open the capabilities companion when the question is …

How to install
mdr add nvidia/skills/doca-pcc@sha256:0de942d6c9d057ddThe 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.
