TDQS

A3.7/5.0
Behavior3/5

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

No annotations are present, so the description carries the behavioral disclosure burden. The word 'Click' transparently states the core action, but the description does not disclose coordinate space, whether it synthesizes press/release events, or what return/error behavior to expect. It is minimally adequate but leaves gaps.

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

Conciseness5/5

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

The description is a single, direct sentence with no filler. The key scoping information ('running Godot game window') is front-loaded, and every word earns its place.

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

Completeness3/5

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

For a simple three-parameter input tool with no annotations and no output schema, the description plus schema is minimally callable. However, it leaves out the coordinate system, any mention of the return value, and details about the synthesized click event, so it is complete enough to attempt a call but not fully informative.

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

Parameters3/5

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

Schema description coverage is 100%, so x, y, and button are already documented in the schema. The description adds only the context that the click position is in the game window, which is useful but does not meaningfully extend parameter semantics beyond the schema.

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

Purpose5/5

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

The description uses a specific verb ('Click') and a specific resource ('position in the running Godot game window'), clearly stating what the tool does. It is easily distinguishable from sibling tools like game_mouse_move or game_mouse_drag, even without naming them.

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

Usage Guidelines3/5

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

The description implies the tool is for clicking inside a running Godot game window, which gives some context. However, it does not explicitly say when to prefer this over alternatives such as game_mouse_move, game_mouse_drag, or game_key_press, nor does it give exclusion criteria.

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