Use this skill when the user is invoking the DOCA PCC Counters tool — the `pcc_counters.sh` bash script under the DOCA tools directory — to arm and read the fixed firmware/hardware PCC (Programmable Congestion Control) diagnostic counters (CNP, RTT, WRED-drop, etc.) on a ConnectX / BlueField device via mst + the mlx5 debugfs `diag_cnt` interface. The script takes two positional args — `set | query` and an mst device path — with no `--help` or subcommands. Trigger even without "pcc_counters.sh…
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 Counters (`pcc_counters.sh`) ## Examples - **"How do I read the PCC diagnostic counters on this device?"** — this is in scope. Arm then query; do not treat this as PCC algorithm tuning. - **"The script printed ERROR: Bad Device."** — resolve the mst path before assuming firmware is broken. ## Instructions Follow Loading order below. Open the tasks companion for run / debug. Open the capabilities companion for the fixed counter set. Do not open every companion file. **Where to start:** This is a tool skill for invoking `pcc_counters.sh` — a small bash script that arms and reads the device's fixed set of firmware / hardware **PCC diagnostic counters** (CNP count, RTT-perf, WRED-drop, RTT-gen, handled events) through the mlx5 debugfs `diag_cnt` interface. Open the tasks companion and start at `## run` for the canonical `set`-then-`query` sequence, or `## debug` when the user reports *"`ERROR: Bad Device`"*, *"counter stuck at zero"*, or *"the dump is empty"*. Open the capabilities companion when the question is *which counters the script reports and how it reaches them*. If the user has not installed DOCA / MFT yet, route to `doca-setup/SKILL.md` first. …

How to install
mdr add nvidia/skills/doca-pcc-counters@sha256:63c88427fb4822c1The line at the top of this page pins the label git:20261022.a4cf47e, 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.
