System Set Finder Path Bar

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

The description discloses no behavioral traits: no mention that this modifies Finder UI state, whether it requires special permissions, whether the change is persistent, or what the side effects are. The annotations only declare openWorldHint, idempotentHint, and destructiveHint as false, so the description carries the full burden and fails to provide any useful behavior context.

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 extremely short and front-loaded, but this is under-specification rather than effective conciseness. It contains only a name restatement and a generic statement about being exposed through Apple-Tools-MCP, neither of which earns its place as useful content.

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 tool that mutates a Finder UI setting, the description is severely incomplete. It does not define what the Finder path bar is, what enabling or disabling it does, or how an agent should determine the desired value. Even though an output schema exists, the missing behavioral and parameter semantics make this definition inadequate for correct invocation.

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 single 'enabled' boolean parameter has no schema description. The tool description does not explain what 'enabled' means, what value to pass, or what the resulting behavior would be. The description adds no meaning beyond the parameter name itself.

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 only restates the tool name ('system_set_finder_path_bar') and says it is a 'Delegated Apple domain tool' exposed through Apple-Tools-MCP. It never states what the tool actually does, such as showing or hiding the Finder path bar. This is essentially a tautology with no actionable purpose information.

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?

There is no guidance on when to use this tool versus alternatives. The sibling list includes similar system_set_* tools such as system_set_finder_status_bar and system_set_show_hidden_files, but the description provides no conditions, exclusions, or selection criteria to differentiate them.

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