nex_browser_close

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

The destructiveHint annotation already signals the destructive nature, and the description's 'Close' is consistent. However, the description adds no additional behavioral context beyond the annotation, such as consequences (e.g., terminated sessions, unsaved data) or relationship to disconnect. It does not contradict annotations.

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 short sentence with no filler or repetition. It is appropriately concise for a simple action, and the 'one or more' phrasing adds necessary scope without clutter.

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 destructive annotation, multiple parameters, and the existence of close-related siblings (disconnect, tab_close), the description is incomplete. It does not address how closing environments differs from disconnecting, what happens to browser processes, or what the expected outcome is, without an output schema.

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%, and the description only says 'one or more' without explaining that windowId refers to the environment identifier(s) or how to obtain them. The optional teamId is not mentioned at all. This minimal hint adds little meaning beyond the schema's type/optionality info.

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 ('Close') and resource ('NexBrowser environments'), and explicitly mentions 'one or more', indicating support for multiple targets. This distinguishes it from related tools like nex_browser_tab_close (tabs) or nex_browser_disconnect (connections).

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?

There is no guidance on when to use this tool versus alternatives like nex_browser_disconnect, nex_browser_tab_close, or nex_browser_open. The description provides no context about prerequisites or typical use cases, leaving the agent to infer distinctions from sibling names.

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