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

With no annotations, the description carries the burden of explaining behavior. It discloses the span-dependent 2D/3D output, which is valuable. However, it doesn't mention other behavioral aspects like how the shape integrates into the study or what the output object is, leaving some gaps.

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 a single sentence that efficiently communicates the core function and the key parameter behavior. There is no unnecessary verbosity or repetition of schema details.

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 tool has an output schema, so return-value details are not required in the description. The description captures the main functional behavior (2D vs 3D) and is sufficient for a creation tool with straightforward parameters and sibling context.

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 no descriptions (0% coverage), and the description only clarifies the 'span' parameter's effect. Other parameters like 'code', 'chord', and 'closed_te' are left to inference. This partial compensation is adequate but not comprehensive.

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 NACA 4-digit airfoil' with a specific verb and resource, distinguishing it from sibling tools like create_box or create_cylinder. It also adds the important 3D/2D distinction based on span, making the purpose unambiguous.

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 the tool is for creating NACA airfoils, which is distinct from other shape tools. It doesn't explicitly mention when not to use it, but the context is clear enough for an agent to select it when an airfoil geometry is needed.

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