rb209_soil_nutrient_indices

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

There are no annotations, so the description carries the full burden of disclosing behavior. It establishes that this is a read-only GET returning a filtered list, but it does not mention response shape, pagination, availability conditions, or any error behavior, which leaves meaningful gaps for an agent deciding how to invoke it.

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?

A single, front-loaded sentence with the endpoint and filter criteria; no redundant or filler text. Every word contributes to describing the tool.

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?

For a simple three-parameter list endpoint with full schema coverage, the description is minimally sufficient. However, with no output schema and many closely related sibling tools, it lacks guidance on how this filtered list relates to rb209_soil_nutrient_indexes or the by-value/by-index variants, so the agent may still need to inspect those tools to choose correctly.

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 coverage is 100%, so the schema already documents all three parameters. The description merely restates the filter-by-IDs idea without adding format, range, or relationship details, which meets the baseline but adds no extra value.

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 names the HTTP verb and resource ('GET /api/Soil/NutrientIndices/...') and states that it returns a filtered list of nutrient indexes filtered by three specific IDs. This is specific enough to identify the operation, though it does not explicitly contrast with the similarly named sibling rb209_soil_nutrient_indexes.

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?

The description implies when to use the tool: when a filtered list of nutrient indexes is needed by nutrient, methodology, and country IDs. However, it offers no explicit when-not-to-use guidance or alternatives, leaving the agent to infer the choice among the many soil nutrient index siblings.

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