click_element

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

With no annotations, the description carries the full burden for behavioral disclosure. It states the action but does not reveal side effects, required permissions, waiting behavior, or what happens after the click (e.g., whether it returns after page load or handles navigation). The mention of 'JS triggers' hints at interactive behavior but is not a substantive disclosure of risks or guarantees.

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 concise sentence that leads with the primary action and immediately adds a relevant qualifier. Every word earns its place; there is no unnecessary fluff or repetition.

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?

The presence of an output schema covers return values, but the description is still incomplete. It fails to explain the timeout_profile parameter, does not mention error behavior (e.g., element not found), and does not offer guidance on choosing among sibling tools like browser_click or browser_navigate. The use-case qualifier adds some completeness but the overall guidance is minimal for a tool with three parameters and no annotations.

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. It implicitly clarifies 'url' (navigate to this URL) and 'selector' (click this element), but it does not define what format the selector should take (CSS, XPath) and completely ignores 'timeout_profile'. This is insufficient given the lack of schema-level descriptions.

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: 'Navigate to URL and click an element.' It also provides a specific use case ('for JS triggers, expanding sections') that distinguishes it from sibling tools like browser_navigate (navigation only) and browser_click (clicking without navigation). The verb+resource combination is unambiguous.

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 implies when to use the tool by adding 'for JS triggers, expanding sections,' which gives clear context. However, it does not explicitly mention alternatives or state when not to use it. It lacks explicit exclusions or comparisons to browser_click or browser_navigate, but the context is enough to infer typical use.

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