Each tool has a clearly distinct purpose: defaults-read and defaults-write handle reading and writing specific key-value pairs, find searches for entries containing a word, and list-domains enumerates available domains. There is no overlap or ambiguity between these functions.

The naming is mixed: defaults-read and defaults-write follow a consistent verb-object pattern with hyphens, but find and list-domains use different conventions (single verb vs. verb-noun with hyphen). While readable, this lacks a uniform pattern across all tools.

With 4 tools, the count is reasonable for a macOS defaults management server, covering core operations like read, write, search, and domain listing. It is slightly thin but functional, as additional tools like delete or reset might be useful but are not essential for basic workflows.

The toolset covers essential CRUD-like operations for macOS defaults: read and write handle key-value management, find enables searching, and list-domains provides discovery. A minor gap exists with no explicit delete or update tool, but agents can work around this using defaults-write or other methods.
