Use this skill when the user is doing hands-on deployment, tuning, or evaluation of the DOCA-shipped Zero-Touch RoCE RTT-based Congestion Control (ZTR RTTCC) reference algorithm on a BlueField-3 DPA — wiring `doca_pcc_dev_ztr_rttcc_algo` into the shipped DOCA PCC sample, picking a variant (vanilla / PM / RX-rate / multipath / window-probeless) at DPACC build time, tuning host-set parameters, or diagnosing `DOCA_PCC_DEV_STATUS_FAIL` from the algorithm.

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 (a BlueField-3-generation
device per the README), the BlueField firmware has the
custom-PCC slot enabled, the DPACC compiler is installed at
a matched version per the DOCA Compatibility Policy, and the
user is doing hands-on deployment of the DOCA-shipped ZTR
RTTCC reference algorithm on a BlueField port that
already carries RoCE-v2 traffic — i.e. either deploying it
as the no-config-required baseline, tuning its documented
parameters, or evaluating it against a custom algorithm the
user intends to write. Open TASKS.md if the
user wants to do something (install / configure / build /
modify / run / test / debug / use); open
CAPABILITIES.md when the question is
what does the algorithm express, what are its variants and
parameters, what does it ship vs not ship. If the user has
not installed DOCA yet, route to
doca-setup first; if the user
has not stood up the host-side doca-pcc framework yet,
route to doca-pcc first (this
algorithm is a library consumed by the PCC framework, not
a standalone program); if the user only wants to inspect
PCC counters at runtime without changing the running
algorithm, route to
doca-pcc-counters;
if the user wants to write their own algorithm from
scratch, that is the doca-pcc library plus the public
PCC programming guide — this skill is for the shipped
reference algorithm specifically.
