memory_vector_search: query cannot be empty

Error message

memory_vector_search: query cannot be empty

What it means

The vector search tool parsed its arguments successfully but `query` was an empty (or whitespace-only) string. Because an empty query cannot produce a meaningful embedding, the tool rejects it before loading config or contacting the embedding provider — a semantic input guard that fires even though the shape of the arguments was valid.

Solutions

1. Provide a non-empty search query string
2. Trim input client-side and fall back to a sensible default term instead of sending an empty string
