launch_gui

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

With no annotations, the description carries the burden of behavioral disclosure. It does convey the key side effect: launching a visible GUI and keeping it driven by subsequent operations. But it omits other behavioral traits an agent may need, such as whether it blocks, whether repeated launches are allowed, or what cleanup/shutdown implications exist.

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?

Two crisp sentences with no filler. The primary action is front-loaded, and the consequential behavioral detail (GUI remains live-driven) follows immediately. Every word earns its place.

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 description is complete for the bare act of launching, and an output schema is present, so return values need not be described. However, with no annotations and zero parameter documentation, an agent cannot fully understand how to control the launch via port or model_path, nor what conditions must hold for the bridge to be 'loaded'. This leaves a meaningful gap.

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%, so the description needed to explain what 'port' and 'model_path' mean and how they affect the launch. It does not mention either parameter at all. While the parameter names are somewhat self-explanatory, the description adds no semantic value beyond the bare names and defaults.

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 ('Launch') and names the resource ('COMSOL desktop GUI') with a distinguishing qualifier ('with the live bridge loaded'). This clearly differentiates it from siblings like connect_gui and shutdown_gui without needing their schemas.

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 description implies use-before-follow-up-operations ('Operations issued afterwards drive the visible GUI in real time'), which gives useful context. However, it does not explicitly state when to prefer this over connect_gui or whether launch_gui is only for first-time startup, leaving the routing partially inferred.

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