invalid arguments for memory_hybrid_search: {e}

Error message

invalid arguments for memory_hybrid_search: {e}

What it means

Argument-deserialization wrapper in the memory_hybrid_search tool's execute: args failed to deserialize into the tool's Args struct (bad types for query/profile/limit/include_breakdown — e.g. limit outside the declared 1–50 is rejected later, but a non-integer fails here). Generic sentinel with the serde detail in `{e}`.

Solutions

1. Include query and namespace strings
2. Use mode values balanced/semantic/lexical/graph_first and limit 1-50
3. Fix malformed JSON
