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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions clicking UI elements but fails to detail critical aspects like error handling (e.g., what happens if the path isn't found), side effects (e.g., whether it triggers modal dialogs or changes application state), or performance considerations (e.g., interaction delays). This leaves significant gaps for a tool that interacts with a UI.

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, efficient sentence that front-loads the core action and target without unnecessary words. Every part earns its place by specifying the verb, resource, and method, making it highly concise and well-structured.

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?

Given the tool's complexity (UI interaction with 2 parameters), no annotations, and an output schema (which might cover return values), the description is minimally adequate but incomplete. It states the basic purpose but misses behavioral details and parameter guidance, leaving room for improvement in context.

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%, so the description must compensate but adds minimal param semantics. It implies 'path' is for visible text labels but doesn't explain the array structure (e.g., hierarchical menu levels) or 'timeout_sec' usage (e.g., waiting for UI elements). With 2 parameters and low coverage, this is inadequate.

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 target ('a menu or menu-like UI path by visible text labels'), making the purpose understandable. It doesn't explicitly distinguish from sibling tools like 'pix4d_click_text' or 'pix4d_send_hotkey', which might offer alternative UI interaction methods, so it falls short of a perfect score.

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?

The description provides no guidance on when to use this tool versus alternatives, such as 'pix4d_click_text' for clicking non-menu text or 'pix4d_send_hotkey' for keyboard shortcuts. It lacks context about prerequisites, like needing the UI to be in a certain state, or exclusions, such as not working on hidden elements.

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