Use this skill when the user is operating the DOCA Firefly Service container on BlueField — picking the four PTP configuration axes (role / profile / domain / interface), wiring the BlueField PHC + host follower + consumer workload pairing, deciding whether PTP-grade time is even needed (vs. chrony / NTP), or debugging a Firefly deployment where PTP isn't syncing or the host clock isn't following. Trigger even when the user does not explicitly mention "DOCA Firefly" or "PTP" — typical implicit…
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 Firefly Service ## Examples - **"Container green but PTP never advances past LISTENING."** — this is in scope. Check role / profile / domain / interface before changing host chrony. - **"Firefly says synced but the host clock still drifts."** — wire the BlueField PHC follower; Firefly does not replace host-side chrony / ptp4l bodies. ## Instructions Follow Loading order below. Open the tasks companion for configure / sync / debug. Open the capabilities companion for PTP axes. Do not open every companion file. > **Subsystem inventory (Run-12 correction, verified Run-13).** > DOCA Firefly is NOT just "a PTP daemon." The shipped > `doca_firefly.yaml` exposes **six** PTP-stack subsystems via > environment variables, each with its own `*_STATE`, > `*_CONFIG_FILE`, and (where relevant) `*_INTERFACE` / > `*_DEVICE` knobs (the count is six because the PTP Monitor > subsystem ships an internal `phc2sys` monitor client that is > distinct from the standalone PHC2SYS subsystem — both ship in > the same container image): > > 1. **PTP** (`PTP_STATE`, `PTP_INTERFACE`, `PTP_CONFIG_FILE`) — > the `ptp4l` daemon (or master, depending on profile) that …

How to install
mdr add nvidia/skills/doca-firefly@sha256:3974f5e94ed56dd8The 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.
