CreateDomain

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

No annotations provided, so description must carry full burden. It only mentions 'creates... in initial state' but does not disclose that activation is performed by default (based on 'activate' parameter defaulting to true). No mention of transport requirements, reversibility, or effects on dependent objects.

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?

Description is verbose with redundant phrases: 'Operation: Create. Subject: Domain.' and 'Will be useful for creating domain.' The core message could be conveyed in one sentence.

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 13 parameters and nested fixed_values array, the description lacks high-level context such as the purpose of fixed values, the interplay between datatype and length, or the necessity of transport requests for non-local packages. The minimal description does not adequately guide an agent on completing complex inputs.

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 has 100% description coverage for all 13 parameters, so baseline is 3. The tool description itself adds no parameter-specific information beyond the schema.

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?

Description clearly states the action ('Create') and the resource ('a new ABAP domain') with specific context ('in SAP system'). It distinguishes from sibling tools like CreateDataElement or CreateClass by naming the specific object type.

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?

No guidance on when to use this tool versus alternatives (e.g., CreateDataElement for data elements, or ActivateDomain for activation). No mention of prerequisites or scenarios where other tools are preferred.

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