Missing 'namespace' parameter

Error message

Missing 'namespace' parameter

What it means

The memory recall tool was invoked without a `namespace` string argument. `namespace` is first in the schema's `required` list (along with `query`) and is read before any search runs, so this is a missing-argument guard: the args object had no `namespace` key or a non-string value, and the store lookup cannot proceed without knowing which namespace to search.

Solutions

1. Include `namespace` in the tool call, e.g. 'global', 'background', 'autocomplete', or 'skill-{id}'
2. Ensure the value is a JSON string, not null or another type
3. Verify required args against the tool schema before invoking
