add_ddns

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states 'Add DDNS' without explaining side effects, required permissions, validation behavior, or the structure of the created resource. This is insufficient for a mutation tool with 6 parameters.

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 extremely short, but this is under-specification rather than conciseness. It fails to use the available space to convey necessary information, making the tool effectively undocumented.

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 tool has 6 parameters (4 required), no annotations, and an output schema that is not described. The description adds no context about error handling, success indicators, or how this DDNS addition fits into the broader network configuration. It is wholly inadequate for a create operation in a complex system.

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%, meaning the schema provides no descriptions for the 6 parameters. The description offers no parameter explanations, making it impossible for an agent to know what 'provider', 'interface', or 'enabled' mean or how they relate to DDNS configuration.

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 '添加 DDNS' is a direct Chinese translation of the tool name 'add_ddns', restating the name without adding any detail. It does not specify what DDNS means or what resource is being added, failing to distinguish it from siblings like get_ddns_config or delete_ddns.

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 such as get_ddns_config or delete_ddns. There is no mention of prerequisites, use cases, or exclusion scenarios.

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