ncloud_cdss_get_vpc_list

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

The readOnlyHint annotation already covers safety. The description adds the qualifier 'available', implying a filtered list, but doesn't define what 'available' means (e.g., region, subnet availability). It provides some context but lacks depth.

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?

A single, front-loaded sentence that is concise and free of filler. Every word contributes meaning, with 'available' and 'for CDSS cluster creation' adding value.

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 zero-parameter read-only lookup, the description is complete enough. It explains what it returns (a list) and why (CDSS cluster creation). Without an output schema, it could specify return fields, but the simplicity of the tool makes this acceptable.

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?

With zero parameters and 100% schema coverage, there is nothing to explain. The baseline for 0 params is 4, and the description correctly focuses on purpose rather than parameters.

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 states a specific verb ('Get') and resource ('VPC list') with a clear context ('for CDSS cluster creation'). It distinguishes itself from generic VPC tools by targeting CDSS, though it doesn't explicitly differentiate from siblings like ncloud_list_vpcs.

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 phrase 'for CDSS cluster creation' provides clear usage context: use this tool when preparing to create a CDSS cluster. However, it does not mention alternatives or when not to use it, though the CDSS-specific name helps.

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