fusion_export_iges

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

The description discloses the license restriction, which is a behavioral constraint, but does not explain other traits like whether it modifies the document, creates a file, or handles the path parameter. Annotations provide readOnlyHint=false and openWorldHint=true, but the description adds little beyond the restriction.

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 extremely concise, consisting of two sentences with no unnecessary words. It is front-loaded with the tool's purpose and efficient in its use of space.

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?

While the description adequately covers purpose and usage, it is incomplete due to the lack of parameter documentation. For an export tool, understanding the path parameter is crucial. The absence of an output schema is acceptable, but the missing parameter info is a significant 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?

The description does not explain the 'path' parameter at all. With 0% schema description coverage, the description carries the full burden of clarifying parameter semantics, but it fails to do so, leaving the agent guessing about its purpose (likely an output file path).

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 tool exports the whole design to IGES format (.igs), using a specific verb and resource. It distinguishes itself from sibling export tools like fusion_export_step by mentioning the format and license restriction.

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 provides explicit usage guidance: it notes that IGES export is restricted on personal-use Fusion licenses and recommends preferring STEP for CAD interchange. This helps the agent decide when to use this tool versus alternatives.

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