# Doca Common

> 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 docactx lifecycle, discovering docadev / docadevinfo and gating on docacap before trusting a feature, wiring docammap / docabufinventory / docabuf for zero-copy I/O across libraries, driving docape for completions, or DOCA Log's two-tier (--sdk-log-level vs app-side) model. Trigger even when the user does not say "DOCA Common" — typical implicit phrasings include "my tasks submit but nothing completes", "DOCAERRORBADSTATE from docactxstart", "--sdk-log-level does nothing for my DOCALOGDBG lines", "share a buf between docadma and docardma", or "crashes far from the offending line". Refuse and route elsewhere for per-library questions in isolation (load doca-flow / doca-rdma / doca-eth alongside), installing DOCA (doca-setup), or doc lookup (doca-public-knowledge-map).
