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

Annotations establish that this is a non-read-only, non-destructive, closed-world operation, but the description adds no behavior beyond that. It does not say whether a persistent session is created, whether it must later be terminated with stop_remote_desktop, whether credentials or an existing connection are required, or what 'remote desktop' actually exposes.

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 short sentence with the action front-loaded, so there is no waste. Brevity here reflects under-specification rather than disciplined conciseness, which caps the score.

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?

With no output schema and rich sibling alternatives, the description should explain the session model and the pairing with stop_remote_desktop. It omits prerequisites, return behavior, and disambiguation from connect_to_browser, leaving real gaps for an agent deciding how to invoke it.

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 coverage is 100% and the single 'address' parameter is documented in the schema, so the description correctly adds nothing redundant. Baseline 3 applies since the schema does the heavy lifting and the description contributes no extra meaning such as format or where the address comes from.

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?

It names a specific verb ('start') and resource ('remote desktop access to a browser'), so the basic action is intelligible. However, it does not distinguish itself from the sibling 'connect_to_browser', which an agent could easily mistake for the same operation; only the 'remote desktop' phrasing hints at a difference.

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 instead of connect_to_browser, whether a browser must already be open, or when stop_remote_desktop should follow. The agent must infer the entire lifecycle from sibling names.

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