Missing 'flavour' parameter

Error message

Missing 'flavour' parameter

What it means

Required-parameter guard in a memory flavour-listing tool's execute: the `flavour` argument selecting which flavour to query is absent or not a string. The tool is read-only (PermissionLevel::ReadOnly, explicitly pinned) so this fires before any guard/driver access and nothing is written.

Solutions

1. Pass the required "flavour" string from the tool's documented enum
2. Check the tool call included all required fields
