create_line_width_section

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

Annotations indicate a mutating operation (readOnlyHint=false) and the description matches by saying 'Create', so there is no contradiction. However, the description does not disclose side effects such as behavior when a section with the same name already exists, coordinate system context, or error conditions. Since the annotations are mostly uninformative false flags, the description carries the burden and adds little beyond the action itself.

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 compact and front-loaded with the action, followed by a clean Args section. The Chinese translations add some redundancy but improve accessibility for bilingual users, and no sentence 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?

For a two-parameter creation tool, the parameter format is well explained, and the tool is probably callable as-is. But the description omits integration context such as whether a model must be active, whether sections are added or replaced, what units are expected, and what happens on invalid input. It is adequate but not complete, especially with no output schema to describe results.

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?

The schema provides only names and types (0% coverage), but the description compensates well by defining 'name' as the section name and giving an explicit format for sec_lines as [[y1, z1, y2, z2, thickness], ...]. It lacks units and coordinate-system details, so it is not a full 5, but it makes the parameters meaningfully actionable.

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 verb 'Create' and the resource 'line-width cross-section', with a helpful Chinese translation. It is specific enough to distinguish this from most sibling section tools, but it does not explicitly differentiate it from create_polygon_section or create_section, so it stops short of 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?

No guidance is provided about when to use this tool versus the many sibling section-creation tools, nor about prerequisites or exclusions. The only implied usage is the tool's name and one-line purpose, which is insufficient given the large set of similar tools.

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