trigger_action

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

No annotations are provided, so the description carries the full burden. It discloses the selection method and lack of DOM traversal but does not mention side effects, error behavior, or prerequisites (e.g., element visibility, scrolling, event triggering). This is insufficient for a mutation tool.

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 that conveys the core action, target, and distinguishing feature with no redundant words. It is appropriately concise for a simple interaction tool.

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?

With an output schema present, return values are covered. The description provides the essential invocation details but lacks usage context and behavioral specifics. It leaves ambiguity around parameter combination and side effects, relying on the agent to infer the rest. Adequate but with noticeable gaps.

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?

The schema has 0% description coverage, but the description compensates by mapping 'name' to an HTML id and 'text' to visible text. It clarifies both parameters meaningfully. However, it does not explain what happens if both are provided or that they are optional, missing some nuance.

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 tool clicks a button/link using either an HTML id ('name') or visible text ('text'). It also distinguishes itself from sibling tools by explicitly noting 'without DOM traversal', which differentiates it from other click-related tools.

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 phrase 'by html id (name) or visible text' implies a specific use case, but it does not explicitly name alternatives or exclusion conditions. There is no direct guidance on when to use this tool versus siblings like click or find_element, leaving the agent to infer the appropriate context.

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