click

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

Annotations already declare that this is not read-only, is open-world, and is not destructive. The description adds no behavioral context beyond that: it does not say whether clicking waits for actionability, may trigger navigation, or what side effects to expect. The selector syntax it provides is parameter semantics rather than behavioral disclosure.

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 front-loaded sentence with no filler. It efficiently conveys the core action and target formats.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. However, with 0% schema coverage the missing explanation of `double` and the absence of any click behavior detail leave this inadequate for a browser interaction tool.

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 carry the parameter burden. It explains the selector parameter well by naming snapshot refs (e12) and CSS/text forms, but it completely omits the `double` boolean parameter, leaving half the parameters undocumented.

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 states a specific verb (click) and resource (an element), and it specifies acceptable target formats (snapshot ref e12 or CSS/text selector). It does not explicitly distinguish itself from nearby siblings such as hover or type_text, so it is clear but lacks sibling differentiation.

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?

It implies that the tool is used for clicking, but it gives no when-to-use guidance, no exclusions, and no alternatives such as hover or type_text. An agent must infer the selection context from the tool name and sibling list.

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