nex_browser_disconnect

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

With no annotations, the description must bear the full transparency burden. It discloses one key behavioral trait (does not close the environment) but omits details such as whether the session can be reconnected, what happens to running automation, or the effect of omitting sessionId. This is adequate but minimal.

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, well-structured sentence that front-loads the action and includes the key qualifier. No wasted words; every phrase adds value.

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?

The tool has one optional parameter, no annotations, and no output schema, so the description is the sole source of guidance. It explains the core action but leaves out essential information about sessionId usage, preconditions, and post-disconnect state, making it incomplete for an agent to invoke confidently.

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%, yet the description does not mention the sessionId parameter at all. It provides no guidance on what sessionId refers to, whether it is required, or what happens if omitted. The description completely fails to compensate for the schema's lack of detail.

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 uses a specific verb ('Disconnect') and resource ('automation session') and clearly distinguishes the tool from its sibling nex_close_browsers by stating it does not close the NexBrowser environment. This is a precise, non-tautological description.

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 phrase 'without closing the NexBrowser environment' provides clear context for when to use this tool relative to closing the environment, implying a distinction from nex_close_browsers. However, it does not explicitly name alternatives or state exclusions, so it falls short of a 5.

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