rb209_field_site_class

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

No annotations are provided, so the description carries the behavioral disclosure burden. It conveys that this is a read-only GET operation returning the site class for the given ID, which is minimal but adequate for a simple lookup. It does not mention error behavior or response format.

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, compact sentence with the HTTP method and resource path front-loaded. It is appropriately sized, though the phrasing 'Site class of site class id provided' is slightly redundant with the endpoint.

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 single-parameter GET lookup with no output schema, the description is nearly sufficient. However, it leaves undefined what a site class represents, what a successful response looks like, and how invalid IDs are handled.

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% and the parameter is self-evidently the ID used to fetch the site class. The description adds no semantic detail beyond the schema, so the baseline score of 3 applies.

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 a specific verb and resource: GET a site class by siteClassId. This differentiates it from list-style siblings like rb209_field_site_classes, though it does not explicitly distinguish itself from rb209_field_site_class_item.

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 sibling tools, such as rb209_field_site_classes or rb209_field_site_class_item. The description provides no context about the domain or selection criteria.

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