GetDomain

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

No annotations are provided, so the description carries the full behavioral burden. It implies a read-only lookup and describes the payload contents, but says nothing about error behavior for unknown domains, authentication/system prerequisites, or whether results are cached. For an annotation-free tool this is thin.

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 resource and the returned fields, no filler or redundancy. Every clause earns its place.

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?

With no output schema, the description must convey return content, and it lists the key result fields (data type, length, fixed values, conversion exit). It is largely sufficient for a single-parameter lookup, though usage context and failure behavior are absent.

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?

Only one parameter exists and schema coverage is 100%; the schema itself supplies the parameter description plus examples (MATNR, BUKRS, LIFNR). The description adds no additional meaning about the domain_name argument, so it sits at the baseline for fully documented schemas.

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?

States a specific verb ('Retrieve') and resource ('ABAP domain definition') and enumerates the returned content (data type, length, fixed values, conversion exit), which cleanly separates it from sibling getters like GetDataElement or GetTable. It does not explicitly say how it differs from GetDataElement, but the resource is unambiguous.

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 alternatives such as GetDataElement, GetTable, or GetTypeInfo, nor any preconditions (e.g., domain must exist, system must be selected). The agent must infer usage entirely from the name and resource.

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