Behavior3/5

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

With no annotations provided, the HTTP method 'GET' in the description signals a read-only operation, which is useful behavioral context. However, the description does not disclose potential error cases, authentication requirements, or any other behavior beyond a straightforward fetch. For a simple GET endpoint, this is adequate but not rich.

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?

The description is a single, front-loaded sentence that includes the endpoint, the HTTP method, and the tool's purpose. There is no wasted text or redundant elaboration, making it easy for an agent to quickly parse.

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?

For a one-parameter, read-only lookup tool without an output schema, the description is sufficiently complete. It tells the agent exactly what resource to fetch and how to filter it. The absence of response format details is a minor gap, but the phrase 'Individual soil type' conveys the expected result reasonably well.

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

Parameters3/5

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

Schema description coverage is 100% because the only parameter, soilTypeId, is described as 'The soil type id to filter on'. The description adds little beyond the schema, but it does reinforce the filtering semantics by saying 'filtered by soil type id'. Baseline 3 is appropriate.

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 states a specific HTTP verb and resource ('GET /api/Soil/SoilType/{soilTypeId}') and clearly identifies what the tool does: returns an individual soil type filtered by id. The word 'Individual' helps distinguish this from any collection-style or soil-related sibling tool.

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?

The description implies usage — call this when you need a single soil type by id — but it gives no explicit guidance about when to choose this tool over alternatives, nor any exclusions or context about related soil tools. This is a minor gap since the tool is a simple lookup, but there are many soil-related siblings.

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