get_title

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states what the tool does, not how it behaves—such as whether it waits for page load, returns null on missing title, or throws exceptions. For a tool with no annotation support, this is a notable gap.

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 states the exact operation with zero waste. It is as concise as possible while remaining informative.

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 has no parameters and an output schema exists, the description is largely complete. It does not need to explain return values due to the output schema. Minor gaps like prerequisites (e.g., requiring a loaded page) are not stated, but these are inferred from the sibling set and the simple nature of 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?

There are zero parameters, so the schema is trivially covered. Per the rubric, 0 params baseline is 4. The description adds no parameter-specific information (none needed), so this score 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 states a specific verb ('Get') and resource ('title of the current page'), clearly distinguishing it from siblings like get_current_url and get_text. It is immediately obvious what this tool does and how it differs from related browser-read 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 usage context is implicitly clear: it is used to fetch the page title. However, it does not explicitly mention when to prefer this over siblings or any exclusions. For a simple read operation, this is adequate, though not as explicit as providing alternatives.

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