CreateMetadataExtension

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

With no annotations, the description must bear full burden. It mentions 'initial state' but does not specify activation behavior (though an 'activate' parameter exists), permissions, side effects, or what 'initial state' entails. Incomplete 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?

Three sentences, but the first two ('Operation: Create. Subject: MetadataExtension.') are redundant and tautologically restate the name. The third sentence is the only substantive one. Could be more concise without the 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?

Given the tool complexity (6 params, creation with activation, transport) and lack of output schema, the description fails to provide adequate context about what happens after creation, required transport, or activation defaults. Missing key behavioral details.

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 adds no additional meaning to the parameters; it does not reference or explain any of the six parameters beyond the schema descriptions.

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 action (create) and the resource (ABAP Metadata Extension, with acronym DDLX), making it specific and distinguishable from sibling tools. The additional phrase 'in initial state' adds precision.

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 explicit guidance on when to use this tool versus alternatives (e.g., other Create* tools). No prerequisites, exclusions, or context provided beyond the general creation intent.

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