click

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

With no annotations, the description carries the full burden. It only says 'Click an element on the page' and does not disclose whether the tool waits for element actionability, scrolls into view, throws on missing elements, or any other behavioral traits relevant for browser automation.

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, front-loading the action and target. It is appropriately sized for a simple tool, though it could include more useful context without becoming verbose.

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 no output schema, no annotations, and one parameter, the description is too minimal. It omits key contextual details such as return behavior, error handling, and conditions for a successful click (e.g., element visibility). This is insufficient for an AI agent to reliably invoke the 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 coverage is 100% with a clear description of the 'selector' parameter. The tool description adds no additional parameter semantics, but the schema already documents that it accepts a CSS selector or Playwright text selector, so a baseline 3 is appropriate.

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 element on the page' clearly states the action (click) and the target (an element on the page). It distinguishes from sibling tools since no other tool explicitly performs clicking, though it lacks details like left-click vs. right-click or whether it triggers navigation.

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 guidance is given on when to use this tool vs. alternatives such as 'navigate' or 'apply_selectors'. The description simply states what it does without context on prerequisites or suitable scenarios.

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