Each tool has a clearly distinct purpose: echo returns input, file_read reads files, file_write writes files, and json_transform applies a JQ-like filter. There is no meaningful overlap or ambiguity among the four tools.

The set mostly follows a predictable snake_case resource_action pattern (file_read, file_write, json_transform). The only minor deviation is echo, which is a bare verb rather than a resource_action name.

Four tools is a well-scoped size for a lightweight utility server. Each tool covers a distinct, useful operation without bloat or redundancy.

The file surface supports read and write but lacks obvious companion operations such as listing, deleting, or checking file existence. The JSON tool supports transformation but not validation or parsing, leaving notable gaps for an agent working in this utility domain.
