CreateInterface

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

With no annotations, the description must disclose behavior. It mentions 'initial state' but does not explain permissions, side effects, or whether existing interfaces are overwritten. However, it does confirm the creation action, which is minimal but accurate.

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: Interface.' and 'Will be useful for creating interface' add no value. Could be condensed to one or two sentences.

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?

No output schema is provided, so the description should clarify return values or post-conditions. It only mentions 'initial state' but lacks details on what that means or what the tool returns. Incomplete for a creation tool with multiple parameters.

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 the schema fully documents parameters. The description adds no new meaning beyond the schema; it only repeats that it creates an interface, which is already implied. Baseline score 3 applies.

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 'Create a new ABAP interface in SAP system' and 'Creates the interface object in initial state', specifying the verb (create) and resource (interface), distinguishing it from sibling creation tools for other ABAP objects.

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 like CreateClass or CreateStructure. The phrase 'Will be useful for creating interface' is tautological and does not help the agent decide context.

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