cst_create_polygon_extrude

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

No annotations are provided, so the description must fully convey behavior. It only states the tool creates and extrudes a polygon, but does not disclose whether it modifies existing geometry, whether extrusion is additive or subtractive, how components are managed, or units/coordinate system assumptions.

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 two efficient sentences that convey the core purpose without any redundant or vague wording. Every sentence adds value.

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?

Given the tool is a combination of two operations, the description could explain how the extrusion relates to the polygon (e.g., is height applied along axis after creation?). No output schema exists, but the schema covers inputs sufficiently. Some missing context about material default (PEC) and typical use in antenna design could help.

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%, so baseline is 3. The description adds no additional meaning beyond the schema parameter descriptions (e.g., points, height, axis). It does not provide examples or clarify relationships between parameters.

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 'Create a polygon and extrude it along an axis in CST Studio' as a 'convenience tool combining polygon profile creation and extrusion.' It distinguishes this from siblings like cst_create_polygon3d (polygon only) and cst_create_extrude (generic extrusion) by explicitly combining both operations.

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 mentions it is a 'convenience tool' but provides no guidance on when to use this vs. the separate polygon and extrusion tools, nor any prerequisites or constraints. No when-not-to-use or alternative recommendations are given.

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