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

The description adds context beyond annotations: it specifies that the tool waits for DOMContentLoaded, which is not covered by the destructiveHint annotation. However, it omits details like error handling, page load failures, or history manipulation, which are relevant for a navigation action.

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, well-structured sentence that efficiently conveys the core action and a key behavioral detail. No unnecessary words.

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 description is minimal but covers the essential functionality for a simple tool with two parameters and limited complexity. It could be improved by mentioning error cases or page load timeouts, but it is adequate for basic use.

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 description does not elaborate on either parameter (url or returnSnapshot), despite schema coverage being only 50%. The schema already describes returnSnapshot, but the description adds no value for understanding parameter usage or constraints.

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 (open URL) and resource (current page), including a specific behavioral detail (wait for DOMContentLoaded). However, it does not explicitly differentiate from sibling tools like open_page or navigate_back, leaving potential ambiguity.

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 on when to use this tool versus alternatives such as open_page, navigate_back, or navigate_forward. The description lacks context on prerequisites or constraints, leaving the agent to infer usage.

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