get_page_info

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

No annotations are provided, so the description must disclose behavioral traits. It only mentions retrieving 'title, URL, etc.' without specifying scope, caching, or side effects. The term 'etc.' introduces ambiguity, reducing transparency.

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, efficient sentence that conveys the essential purpose without unnecessary words. It follows the principle of front-loading key information.

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 no output schema and a simple tool, the description is vague with 'etc.' and does not enumerate all returned fields (e.g., metadata, maybe more). This leaves the agent uncertain about the exact output structure, especially compared to other similar tools that might have detailed output.

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 tool has no parameters, so schema coverage is 100%. By the rule, a tool with 0 parameters should receive a baseline score of 4 for this dimension. The description adds no parameter information, but none is needed.

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's purpose: 'Get information about the current page (title, URL, etc.)'. It uses a specific verb ('Get') and resource ('information about the current page'), effectively distinguishing it from sibling tools like click_element or navigate_to_url.

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 when to use (when page info is needed) but lacks explicit guidance on when not to use or alternatives. No exclusions or sibling comparisons are provided, making it minimally adequate.

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