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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, so safety is covered. The description adds nothing beyond them: it doesn't say what happens to the browser session, whether the tab/window closes, or what an agent should expect afterward (unlike close_browser, also a sibling).

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?

A single tight sentence with the action front-loaded and no filler. Brevity is appropriate for a one-parameter tool, though it under-delivers on state-changing context.

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 one-param tool with annotations and no output schema, the description is minimally sufficient to call it. It still leaves open whether a session must exist and how this differs in effect from disconnect_browser or close_browser.

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?

Only one parameter ('address') at 100% schema description coverage, so the schema carries the burden. The description adds no format hints or examples for the address, which is acceptable at this coverage level but not additive.

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?

Names a specific verb ('Stop') and resource ('remote desktop access to a browser'), so the effect is unambiguous. It implicitly pairs with the sibling start_remote_desktop but never names it or states the inverse relationship explicitly, keeping it just under a 5.

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 call this versus alternatives, nor any prerequisite such as an active remote desktop session or connected browser. The agent must infer that start_remote_desktop must have been called first.

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