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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only mentions session handling and lists actions but omits important behavioral traits such as destructive potential, authentication needs (which are in the schema but not the description), rate limits, or error behavior. The description is insufficient for such a complex 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 very concise: two sentences that front-load the purpose and list actions. Every part is essential and there is no wasted text.

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 (25 actions, 8 parameters, no output schema), the description is too brief. It does not explain how steps are structured, error handling, return values, or common usage patterns. While the schema provides parameter details, the description lacks high-level workflow context needed for full understanding.

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 input schema already has 100% coverage with detailed descriptions for all parameters. The main description adds a high-level list of actions but does not deepen parameter understanding beyond what the schema provides. Baseline 3 is appropriate as the schema does the heavy lifting.

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 it is a multi-step interaction workflow and lists all 25 supported actions, making the purpose very specific. It also distinguishes from sibling tools that are single-action (e.g., click_element) by explicitly mentioning the multi-step nature and session handling.

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 usage for multi-step scenarios versus single-action siblings, but it does not explicitly state when to use this tool versus alternatives. It mentions working with existing sessions or ephemeral pages, which provides some context, but lacks clear guidance on exclusions or prerequisites.

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