click_element

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 'with confirmation', hinting at a safety or feedback mechanism, but doesn't elaborate on what confirmation entails (e.g., success/failure response, delays, or side effects). It fails to address critical behaviors like error handling, performance implications, or interaction with browser state, leaving significant gaps.

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 with zero waste: 'Click an interactive element by index with confirmation'. It is front-loaded and appropriately sized for the tool's complexity, making it easy to parse without unnecessary elaboration.

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 (interactive browser operation), lack of annotations, and low schema coverage, the description is incomplete. It doesn't cover parameter meanings, behavioral details, or usage context. While an output schema exists (which might explain return values), the description fails to provide sufficient guidance for safe and effective tool invocation in a browser automation setting.

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%, meaning parameters 'session_id' and 'index' have no descriptions in the schema. The tool description adds no meaning beyond the schema—it doesn't explain what 'session_id' refers to (e.g., browser instance) or how 'index' is defined (e.g., zero-based, element order). With 2 undocumented parameters and no compensation in the description, 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 'Click an interactive element by index with confirmation' states the action (click) and target (interactive element) but is vague about what 'by index' means in practice and doesn't distinguish it from sibling 'click_element_by_xpath'. It provides a basic purpose but lacks specificity about the indexing system or what constitutes an 'interactive element'.

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 explicit guidance on when to use this tool versus alternatives like 'click_element_by_xpath' is provided. The description implies usage for clicking elements via index, but it doesn't specify prerequisites (e.g., needing an active browser session) or exclusions, leaving the agent to infer context from sibling tools.

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