Look up asteroid or comet data from NASA JPL Small-Body Database by designation, number, or name. Get physical parameters, orbital elements, NEO/PHA flags, and Earth MOID.

Instructions

Asteroid/comet physical + orbital parameters from NASA JPL Small-Body Database by designation, number, or name (e.g. "433 Eros", "1P/Halley", "2024 YR4"). NEO/PHA flags, diameter, albedo, orbit class, eccentricity, period, Earth MOID.

Behavior4/5

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

With no annotations, the description carries the burden. It indicates a read-only query behavior and lists return fields, but omits details like whether it returns a single result or list, or error handling.

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

Conciseness5/5

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

One sentence packed with essential information: resource, source, input formats, and output fields, with no wasted words.

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

Completeness4/5

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

Given the simplicity (one parameter, no output schema), the description covers the tool's purpose and data fields well, though it could mention the return format.

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

Parameters4/5

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

The schema describes the parameter and the description adds concrete examples, enhancing understanding beyond the schema alone.

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

Purpose5/5

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

The description clearly states the tool retrieves physical and orbital parameters from NASA JPL Small-Body Database, with specific examples of input formats and data fields, distinguishing it from sibling space tools.

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

Usage Guidelines4/5

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

While it clearly defines the domain (asteroids/comets) and provides examples, it does not explicitly state when to use this tool over siblings or mention any exclusions.

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