Help users work with the Mooncake Python APIs for distributed storage and high-performance data transfer. Use when working with Mooncake Store (distributed KV cache), Transfer Engine (RDMA/TCP transfers), service setup (master, metadata server), PyTorch tensors in the Store, zero-copy/buffer management, batch operations and replication, or Mooncake EP / Backend (Expert Parallelism). Trigger on questions about MooncakeDistributedStore, TransferEngine, put/get, put_tensor, register_buffer, ReplicateConfig, or the mooncake.store / mooncake.engine / mooncake.pg Python modules.
Run Mooncake pre-PR local validation through scripts/run_ci_test.sh. Use this skill whenever the user wants to validate a branch before opening or submitting a PR, run local CI, run ci test, check changes before PR, reproduce GitHub Actions locally, or force a full pre-submit verification. Trigger on phrases like "提交 PR 前验证", "run ci test", "run local CI", "check my branch", "test before PR", "pre-submit validation", and "reproduce CI locally".
Automatically diagnose Mooncake deployment and runtime issues. Checks services (mooncake_master, metadata server), RDMA devices, environment variables, connectivity, memory limits, and analyzes logs for common error patterns. Use when Mooncake deployment fails, services won't start, connections fail, or you encounter runtime errors like "Error from etcd client", "No matched device found", "Failed to register memory", "NO_AVAILABLE_HANDLE", or any RDMA/networking issues. Also use when user asks to troubleshoot, debug, diagnose, or fix Mooncake problems.
