CreateInterface

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

With no annotations, the description carries the full burden. It only states it creates an interface in an 'initial state', but does not disclose side effects, required permissions, or whether existing interfaces can be overwritten. This is insufficient for a mutation 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 redundant phrases like 'Operation: Create. Subject: Interface.' and 'Will be useful for creating interface.' These add no value. The useful information is in the last two sentences, but the overall length is still acceptable.

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 tool has no output schema and no annotations, the description is minimally complete. It conveys the core purpose but lacks details on lifecycle, error conditions, or what 'initial state' means. It suffices for basic understanding.

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 coverage is 100%, so baseline is 3. The description does not add any parameter-level information beyond what the schema provides. It does not explain the role of parameters like transport_request or package_name.

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 the tool creates an ABAP interface, specifying the verb 'create' and the resource 'interface'. It distinguishes this tool from siblings like CreateClass or CreateDataElement by naming the specific object type. The mention of 'initial state' adds context.

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 is provided on when to use this tool versus alternatives like CreateClass or UpdateInterface. There is no mention of prerequisites or when not to use it, leaving the agent without context for tool selection.

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