rb209_arable_potato_varieties

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

No annotations are provided, and the description only says 'GET /api/Arable/PotatoVarieties — The full list of available potato varieties'. It does not disclose whether the list is ordered, whether it includes inactive/legacy varieties, whether any authentication is required, or what the output items' shape is. For a read-only reference endpoint with zero annotation support, the description carries the full burden and provides little beyond the endpoint name.

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 a single sentence that names the endpoint, states what it returns, and adds a scoping qualifier. Every word earns its place; nothing is redundant or missing at a high level.

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 zero-parameter lookup endpoint, the description is largely sufficient: an agent can retrieve the full list and knows it is potato-specific. However, the lack of annotations and output schema means the agent does not know what fields each variety will contain, and the sibling relationship to rb209_arable_potato_varieties_by_group is not spelled out. Some practical context is missing but the core operation is clear.

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 tool has zero parameters, and the schema description coverage is 100%. The description appropriately notes the only meaningful condition ('only required for arable potato crops'), which is extra context beyond the empty schema. There are no parameter semantics to explain, so a 4 is appropriate.

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 states a specific verb ('GET') and resource ('the full list of available potato varieties') and adds a scoping note ('only required for arable potato crops'). It does not explicitly distinguish it from the sibling rb209_arable_potato_varieties_by_group, but the 'full list' wording implies the unfiltered version, which is a useful contrast.

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 the use case: fetch the full list when working with arable potato crops. It does not, however, state when to prefer rb209_arable_potato_varieties_by_group or mention that the latter is the filtered alternative, leaving some routing ambiguity among siblings.

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