# Doca Dma

> Use this skill when the user is doing hands-on DOCA DMA programming — bringing up a docadma context, configuring the single docadmataskmemcpy task type, sizing buffers via the docadmacaptaskmemcpy queries, setting LOCALREADONLY / LOCALREADWRITE permissions on source / destination docammap regions (plus docammapexport for cross-peer copies), driving the progress engine, or debugging DOCAERROR returns. Trigger even when the user does not explicitly mention "DOCA DMA" or "docammap" — typical implicit phrasings include "memcpy host buffer to BlueField without using the CPU", "offload a bulk copy to the DPU", "copy returns NOTPERMITTED on first submit", "buffer too big for one DMA task", "task submitted but no completion", or "scatter-gather copy between two memory regions". Refuse and route elsewhere for cross-network copies (DOCA RDMA), producer/consumer messaging (DOCA Comch), DOCA Core / progress-engine internals, or DOCA install — those belong to other skills.
