jpl_periodic_orbits

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

With no annotations provided, the description carries the full burden of behavioral disclosure but offers none. It doesn't indicate whether this is a read-only query, a computational tool, or a data source; it lacks information on rate limits, authentication needs, output format, or any behavioral traits like pagination 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.

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

The description is under-specified rather than concise—it's a single phrase that fails to convey essential information. While it's brief, it doesn't earn its place by being informative; it lacks structure and front-loading of key details, making it inefficient for agent understanding.

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 the complexity of 11 parameters, no annotations, and no output schema, the description is severely incomplete. It doesn't explain what the tool does, how to use it, or what to expect in return, failing to compensate for the lack of structured data and leaving the agent with insufficient 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 description coverage is 100%, with detailed descriptions for all 11 parameters, so the description doesn't need to add parameter semantics. The description itself provides no additional parameter information, but the schema adequately covers meanings, making a baseline score of 3 appropriate as it doesn't compensate or detract.

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 'JPL Three-Body Periodic Orbits Database' is a tautology that restates the tool name 'jpl_periodic_orbits' without specifying what action the tool performs. It doesn't clarify whether this tool retrieves, searches, lists, or analyzes orbits, nor does it differentiate from sibling tools like 'jpl_horizons' or 'nasa_exoplanet' which might also involve orbital data.

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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention any context, prerequisites, or exclusions, and it fails to reference sibling tools that might handle related data (e.g., 'jpl_horizons' for ephemeris or 'nasa_exoplanet' for exoplanet orbits), leaving the agent without usage direction.

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