rb209_soil_nutrient_target_index

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

The description only restates that this is a GET operation, which implies read-only behavior, but it does not disclose response shape, error behavior, authentication needs, or any other runtime characteristics. With no annotations provided, the description carries the full burden and does not meet 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?

The description is short and front-loaded with the exact endpoint, making it easy to parse. The human-readable gloss adds a little clarity, though it is somewhat redundant with the word 'GET' already present.

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 lookup with three required IDs, the description gives the essential purpose but nothing else. There is no output schema to clarify the return value, and the description does not explain what a nutrient target index is, what values the result can take, or how it differs from related tools.

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 input schema has 100% coverage with descriptions for all three ID parameters, so the baseline is 3. The description adds no further meaning about how these IDs relate to the target index or what values are valid, but the schema already documents the parameters adequately.

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 clearly identifies the HTTP method and resource path, and states that the tool returns the nutrient target index for the given IDs. It is specific enough to know what operation is performed, but it does not explicitly differentiate this from the many similar soil_nutrient_index 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?

The description provides no guidance on when to use this tool versus the numerous sibling tools such as rb209_soil_nutrient_indices or rb209_soil_nutrient_index_by_index. There is no mention of intended context, prerequisites, or alternatives.

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