Close browser debug session

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

The description only says 'close', which matches the destructiveHint annotation. It adds no extra behavioral context such as irreversibility, impact on running processes, or cleanup side effects. With annotations present, the bar is lower, but the description provides no value beyond what the annotation already indicates.

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, clear sentence with no fluff. It is appropriately concise for the action, but the lack of additional information trades simplicity for completeness.

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's simplicity (1 param, no output schema), the description is minimal but misses key contextual details: how to identify/obtain the session_id, and the fact that closing is destructive and likely irreversible. The presence of a similar sibling tool also warrants an explicit usage note. The description is under-specified for safe and correct invocation.

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 does not elaborate on the 'session_id' parameter, such as its format or how to obtain it. The name is somewhat self-explanatory, but the description fails to connect it to the act of closing a session or to mention that the ID likely comes from a session creation/list tool.

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 the target (browser debug session created by SuperDev). The term 'browser' distinguishes it from the sibling 'close_debug_session', though it does not explicitly call out that alternative. It is specific and not a tautology.

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 usage guidance is provided. It does not mention prerequisites (e.g., session must exist) or contrast with alternatives like 'close_debug_session'. The description merely restates the tool's purpose without contextual 'when to use' information.

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