CreateDataElement

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

No annotations are provided, so the description bears full responsibility. It mentions 'initial state' but does not explain what that entails (e.g., inactive, needs activation). No disclosure of side effects, required authorizations, or limitations.

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 short but contains redundancy: 'Operation: Create. Subject: DataElement. Will be useful for creating data element.' Repeats the same idea. Could be more concise without losing meaning.

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 17 parameters, no output schema, and no annotations, the description is insufficient. It fails to clarify the creation process lifecycle (e.g., the need for activation, separate update tools for labels) and does not elaborate on critical parameters like transport_request or type_kind.

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 all 17 parameters are already documented in the input schema. The description adds no additional context or clarification beyond what the schema provides, meeting the baseline of 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 explicitly states 'Create a new ABAP data element in SAP system' which clearly indicates the tool's function. It distinguishes from siblings like CreateDomain or CreateTable by naming 'DataElement'. However, the opening line 'Operation: Create. Subject: DataElement.' is somewhat redundant.

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 alternative creation tools (e.g., CreateDomain for domains, CreateStructure for structures). No prerequisites, no exclusions, and no context about transport requirements or activation steps.

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