System Set Finder Status Bar

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

The description adds no behavioral information at all. Annotations say idempotentHint is false and destructiveHint is false, but the description does not explain persistence, side effects, permissions, or what toggling this setting changes. For a setter with no idempotency guarantee, the agent is left without key behavioral 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 short but not usefully concise; its only sentence spends itself on boilerplate about being an exposed delegated tool. Under-specification masks as conciseness because no actual information is delivered.

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?

Even though the tool has a single boolean parameter and an output schema, the agent cannot tell what setting is being changed, whether it is per-user or global, whether it requires permissions, or what a successful invocation entails. The description is inadequate for safe and 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?

Scema description coverage is 0%, so the description must carry parameter meaning, but it does not. The single required boolean 'enabled' is never explained, such as whether true shows the status bar or hides it. The description adds no value beyond the raw schema.

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 in a generic wrapper: 'Delegated Apple domain tool system_set_finder_status_bar exposed through Apple-Tools-MCP.' It never states the actual action, effect, or scope, so it is effectively a tautology. It also does not distinguish this tool from siblings like system_set_finder_path_bar.

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, what prerequisites exist, or how it relates to alternatives such as system_get_finder_settings or system_set_finder_path_bar. The description provides no context for tool selection.

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