garageband_click_ui

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

Annotations are absent, so the description must bear full behavioral disclosure. It mentions 'first visible' but does not explain what 'visible' means, what happens if no control is found, or whether the click triggers any side effects. The action is clear, but deeper behavioral traits are missing.

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 a single sentence of 13 words, conveying the core action and matching criteria without any fluff. It is optimally concise and front-loaded.

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 with 3 parameters, no annotations, and no output schema, the description lacks completeness. It does not specify return behavior, error handling (e.g., no matching element), or the meaning of 'visible.' Contextual details are minimal, leaving an agent to guess about edge cases.

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?

The description explains name and role (optional), but does not mention the exact parameter. With 0% schema description coverage, the description should clarify all parameters. The meaning of exact (whether to match exactly) is left to inference, which is insufficient.

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 clearly states the action ('Click') and the resource ('first visible GarageBand UI control matching a name and optional Accessibility role'). It distinguishes from siblings like garageband_click_menu (which likely clicks a menu) and garageband_click_ui_search (which searches then clicks) by specifying the matching criteria.

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 guidance is provided on when to use this tool versus alternatives. With multiple sibling click tools (e.g., garageband_click_menu, garageband_click_ui_path), the description should explicitly state the use case, such as 'Use this when you have a UI element name and want to click the first visible match.'

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