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

With no annotations, the description carries the full burden. 'Owned native Gmsh GUI' hints at an app-managed process, but nothing is said about side effects of launching a GUI, behavior if one is already open, display/headless requirements, permission needs, or whether the call is blocking.

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. Slightly jargon-y ('owned native') without explanation, but nothing is wasted.

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?

An output schema exists so return values need not be described, and the 'validated checkpoint' precondition is stated. However, for a tool that spawns a GUI process with no annotations and no parameter docs, the remaining behavioral and usage gaps leave it only minimally complete.

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?

One parameter (session_id) at 0% schema description coverage, so the schema adds nothing beyond the name. The description does not explain the session_id at all, though the name is self-explanatory and consistent with sibling tools.

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?

States a concrete verb and resource ('Launch the owned native Gmsh GUI') plus what it renders ('latest validated checkpoint'), which is more specific than a bare 'view' tool. It is reasonably distinguishable from view_capture/view_set/view_close, though it never names them to sharpen the boundary.

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 when-to-use guidance and no explicit alternatives among the crowded view_* sibling cluster (view_status, view_capture, view_set, view_clip). The only usable signal is the implicit precondition that a validated checkpoint must already exist.

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