System Gui List Menu Bar Items

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is clear. The description adds no behavioral traits, no mention of what menu source is read, and no context about how the listing behaves; it is neutral but empty.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short but earns no place because it merely repeats the tool name. This is under-specification rather than useful conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only listing tool with an output schema, the missing return format is less critical, but the absence of purpose and parameter semantics leaves an agent unable to decide when to invoke it or what the two identifiers control. The description is incomplete, though not dangerously misleading.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description does not explain how bundle_id and application are used or which one to supply. Since the schema provides no parameter descriptions, the tool description should compensate, and it does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description simply restates the tool name ('Delegated Apple domain tool system_gui_list_menu_bar_items exposed through Apple-Tools-MCP') without a verb or resource. It provides no functional statement beyond what the title already conveys, making it a tautology.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No mention of when to use this tool or when to prefer sibling GUI tools like system_gui_click_menu_path or system_gui_type_text. There are no use cases, prerequisites, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
