get_celestrak_gp

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

No annotations provided, so description must disclose behavioral traits. It explains the parameters but does not mention error behavior if multiple identifiers are provided, response format, rate limits, or data freshness. The 'limit' parameter implies multiple records but no details on pagination.

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?

Description is concise with a clear, front-loaded purpose statement and well-structured Args list. Each sentence adds value, though the Args section is a bit verbose but necessary given zero schema descriptions.

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?

Covers purpose, constraints, and parameter meanings. However, without an output schema, it lacks description of the return value structure or behavior (e.g., single vs. multiple records, limit semantics). Siblings are many, but only one alternative is referenced.

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 has 0% description coverage, so description fully compensates by providing explicit examples for each parameter (e.g., catnr: NORAD catalog number (e.g. 25544 for ISS), group: Satellite group name (e.g. 'stations', 'active')). Also clarifies that exactly one identifier is required.

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?

Description clearly states the tool looks up GP ephemeris records from CelesTrak, specifying the resource and source. It also emphasizes that exactly one identifier should be used, distinguishing it from listing tools.

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?

Explicitly states to provide exactly one identifier and recommends using list_celestrak_options() to see available groups. However, it does not explicitly differentiate from other query tools among the siblings (e.g., get_celestrak_satcat).

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