[juanmichelini]

When copying a command like

--repo OpenHands/software-agent-sdk
-f benchmark="terminalbench"
-f sdk_ref="b1235d015b696730ccc1b543e6512402cfc00eab"
-f allow_unreleased_branches="true"
-f eval_limit="1"
-f model_ids="claude-sonnet-4-5-20250929"
-f reason="Direct terminalbench smoke for OpenHands/benchmarks#728 Harbor wrapper stack"
-f eval_branch="main"
-f benchmarks_branch="codex/harbor-covered-wrapper-map"
-f extensions_branch="main"
-f instance_ids=""
-f num_infer_workers=""
-f num_eval_workers=""
-f enable_conversation_event_logging="false"
-f max_retries="3"
-f tool_preset="default"
-f agent_type="default"
-f partial_archive_url=""

it should contain a line --ref {sdk_branch}
