browser_close_page

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

No annotations are present, so the description carries full burden. It only states 'close' without detailing side effects (e.g., whether the page is removed, memory freed, or any prerequisites). The behavioral impact is under-communicated.

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 short but includes a somewhat redundant Args section. It could be more concise, e.g., 'Close a page by its ID.' Every sentence is short, but the structure is minimal.

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 tool with a single required parameter and no annotations, the description lacks completeness. It does not explain how to obtain page IDs, potential errors, or its relationship to sibling tools like 'browser_list_pages'.

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?

Schema description coverage is 0%, meaning the parameter name 'page_id' is not described. The description adds 'Page ID to close', which is essentially a repetition. No extra semantics like format, source, or valid values are provided.

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 closes a page by ID, using specific verb 'close' and resource 'page'. It distinguishes from sibling 'browser_close' which likely does not take an ID, though the difference is not explicit.

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 is provided on when to use this tool versus alternatives like 'browser_close' or 'browser_list_pages'. The description lacks context for when page ID is known versus when to use other tools.

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