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

No annotations are provided, so the description must inform about behavioral traits. It states navigation of the active browser session but does not mention whether it waits for page load or any potential side effects. This is adequate but lacks detail for a full transparency score.

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?

Two brief sentences deliver the essential information without any extraneous content. Every word contributes to clarity.

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?

For a simple one-parameter tool with no output schema, this description covers the primary function and relationship to a sibling. It provides sufficient context for an agent to decide to use it.

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, and the description only says 'to a URL', which merely reiterates the parameter's type and format. It does not add any new constraints, examples, or nuances beyond what the schema already implies.

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?

Description explicitly states 'navigate the active browser session to a URL', providing a specific verb and resource. It distinguishes itself from the sibling 'open_url' by noting it's an alias-friendly alternative, clarifying its role.

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 mentions it is an alias for 'open_url', giving clear context on when to use this tool as an alternative. However, it does not elaborate on any prerequisites or scenarios where one might be preferred over the other.

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