Validate RAP Content

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, which cover the safety profile. The description adds the notion of validation but offers no additional behavioral details, such as what happens on validation failure, whether it returns a report, or any side effects. It does not contradict the annotations.

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 a single sentence with no wasted words. It is front-loaded and easy to read. However, given the tool's complexity, the extreme brevity borders on under-specification rather than conciseness, but it does not contain fluff.

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?

This is a complex tool with 8 parameters, nested objects, and an output schema. The description provides nearly no contextual information beyond the basic purpose. It doesn't explain what 'generated content' refers to, how validation works, or what the expected inputs and outputs are. Even with the output schema available, the description is insufficient for an agent to understand when and how to invoke it correctly.

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 0%, so the description must compensate for explaining the parameters. It does not. The one-sentence description offers no explanation for systemId, generatorId, referenceObjectName, packageName, content, length, offset, or referenceObjectType. The nested 'content' object is especially complex and completely unexplained. Parameter names hint at some semantics, but the description adds no value.

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's purpose: 'Validate RAP initial inputs and optional generated content.' The verb 'Validate' is specific, and the resource is clearly identified as RAP-related inputs/content. This distinguishes it from sibling tools like sap.rap.generate and sap.rap.binding.publish.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention any preconditions, typical workflows, or exclusions. For example, it doesn't say whether to use this before sap.rap.generate or after sap.rap.generate, or how it differs from sap.rap.availability.

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