List Polars

list_polars

Lists Reynolds numbers that have stored polars, letting you check available polar data for an airfoil before reading or analyzing it.

Instructions

List the Reynolds numbers for which stored polars exist.

C2.7/5.0
Behavior2/5

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

No annotations are supplied, so the description carries the full behavioral burden. It implies a read-only enumeration but says nothing about permissions, whether install_dir changes which store is read, or what happens when no polars exist; with no annotations this is a meaningful gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no redundant wording. Its brevity is efficient, though the space saved is spent nowhere useful, which is penalized under other dimensions rather than this one.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The presence of an output schema means return values need not be described, and the tool is simple. However, with zero parameter documentation and no annotations, the definition omits essentials for a tool that requires a 'name' argument and optionally takes an install_dir override.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, yet it never mentions either parameter. It is unstated whether 'name' is an airfoil name and what 'install_dir' controls (a polars data directory override), leaving an agent to guess at required input semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: list the Reynolds numbers for which stored polars exist. That is concrete enough to distinguish it from get_polar (which presumably returns a polar's data), though it never ties the listing to the 'name' input or to siblings like list_libraries.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as get_polar or find_airfoils_by_polar. The agent must infer from the tool name alone that this is a discovery step before fetching a specific polar.

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