invalid arguments for memory_tree_drill_down: {e}

Error message

invalid arguments for memory_tree_drill_down: {e}

What it means

Argument-deserialization wrapper in the memory_tree_drill_down tool's execute: serde_json::from_value failed to shape the raw args into the tool's request struct (e.g. `node_id` missing or wrong type — the schema requires node_id, with optional query and limit). This is a generic sentinel: the inner serde message is embedded, so read the `{e}` text for the exact field at fault.

Solutions

1. Supply node_id as a string from a prior cover_window/query_source result
2. Check query/limit/max_depth types match the schema
3. Fix malformed JSON in the tool arguments
