get_spacetrack_satcat

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

No annotations are provided, so the description must fully convey behavioral traits. It mentions the input requirement and env vars but does not disclose if the operation is read-only, has rate limits, or what the output structure looks like. For a query tool, read-only behavior could be inferred but is not stated.

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 very concise: a one-sentence purpose, a brief requirement note, and a bulleted parameter list. Every sentence adds value, and the structure front-loads the key information.

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?

Given no output schema and no annotations, the description covers the tool's purpose, essential parameters, and prerequisites. However, it lacks details on output format, pagination, or error conditions. For a query tool with five parameters, it is adequate but not fully complete.

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 description coverage is 0%, but the description includes a clear 'Args:' section with explanations for each parameter, adding meaning beyond the bare schema. For example, it notes that 'name' is a substring search and 'object_type' has example values. This is valuable, though it could be more detailed (e.g., allowed values for object_type).

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?

Clearly states it queries SATCAT records from SpaceTrack. Among siblings like get_celestrak_satcat and get_gcat_satcat, the name and description indicate the source is SpaceTrack, distinguishing it. However, the description does not explicitly differentiate it from similar sibling 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?

Provides important context: at least one filter must be provided and environment variables are required. However, it does not specify when not to use this tool or suggest alternatives among the many sibling tools that also query satellite catalogs.

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