rb209_soil_ph_recommendation

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

The description explicitly identifies the call as a GET and says it returns a list, which signals read-only behavior. However, with no annotations, it does not disclose details such as how results are ordered, whether both IDs must correspond to existing records, or what happens on invalid input.

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 compact sentence includes the HTTP method, endpoint path, and return summary with no filler or redundant content. Everything present serves a purpose.

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?

This is a simple two-parameter lookup with no output schema, and the description names the return type. Still, the nature of 'soil ph recommendation level' is vague, and there is no information about cardinality, error behavior, or domain context, making the description adequate but minimal.

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 description coverage is 100%, so the baseline is 3. The description references the parameters only via the URL path and does not add meaning beyond the schema's own descriptions of 'country id' and 'soil type id'.

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 states the operation ('GET') and resource ('SoilPhRecommendation'), plus the return type ('list of soil ph recommendation level'). It is distinguishable from the many sibling RB209 tools by its unique resource, though it does not explicitly contrast itself with any sibling.

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?

There is no guidance on when to use this tool versus the many related RB209 tools, no use-case context, and no exclusions. An agent can only infer usage from the endpoint name and parameters.

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