ncloud_ncr_create_registry

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

Beyond the destructiveHint=false annotation, the description discloses valuable behavioral constraints: the bucket cannot be reused across registries and dryRun=true provides a preview without creating. It stops short of fully describing return formats or side effects, but the annotation plus these details offer solid transparency.

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 two sentences with no filler. It front-loads the primary purpose and immediately follows with crucial usage constraints, making it easy to scan and act on.

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?

For a create tool with only three parameters and no output schema, the description covers the key operational details: what to provide, a constraint on bucket reuse, and the dryRun option. It does not describe the response object, but the simple nature of the operation keeps this from being a major gap.

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%, and each parameter already has a clear description. The tool description does not add new semantic meaning beyond the schema, so the baseline score of 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 the verb (Create), resource (container registry), and linkage (to an existing Object Storage bucket). It is specific and distinguishable from sibling tools like ncloud_ncr_delete_registry or ncloud_ncr_list_registries.

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 clear context on how to use the tool, including the dryRun preview option and the bucket exclusivity rule. However, it does not explicitly mention when not to use this tool or point to alternative tools for related operations.

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