Pull expert skills into this harness from the Rockie platform catalog (~300 skills across ML training/inference, biology, chemistry, physics, databases, coding). Use BEFORE writing domain guidance from scratch or fumbling an unfamiliar framework — if the task names a library (vLLM, GRPO, TRL, AlphaFold, DuckDB, LAMMPS), check the catalog first. Browse `rockie skill catalog --search X --json`, pull into `.agents/skills/`, invoke immediately. Silently no-ops when the Rockie CLI is absent or logged out.
