CreateDataElement

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

No annotations are provided, so the description carries the full burden of disclosing behavioral traits. It only states it creates in 'initial state,' but does not mention prerequisites (e.g., existing package), side effects, or that activation is typically required. This is insufficient for a creation tool.

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 contains redundancy: 'Operation: Create. Subject: DataElement.' and 'Will be useful for creating data element.' are essentially repetitions of the name. It could be more concise and front-loaded with essential information.

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?

Given the complexity (16 parameters, no output schema) and the presence of many sibling tools, the description fails to provide complete context. It does not explain the creation lifecycle (e.g., need for activation), relationships between parameters, or what 'initial state' means.

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 covers 100% of the 16 parameters with descriptions, so the baseline is 3. The tool description does not add any additional meaning or relationships beyond what the schema already provides, so the score stays at 3.

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 it creates a new ABAP data element in SAP system, and adds that it creates it in initial state. This sufficiently distinguishes from sibling tools like CreateDomain or CreateTable. However, the phrasing 'Operation: Create. Subject: DataElement.' is somewhat robotic.

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 CreateDomain (for underlying domain) or ActivateDataElement (for activation after creation). The description does not provide any when-to-use or when-not-to-use information.

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