Get Ddns Config

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

Annotations supply readOnlyHint=true, so the safety profile is covered by structured data. The description adds no behavioral context of its own — no note on what configuration is returned, whether it requires the DDNS feature to be enabled, or how it relates to the sibling config endpoint. With annotations present the bar is lower, but this description contributes essentially nothing beyond the name.

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 short sentence with no padding, appropriately sized for a zero-parameter getter. It is front-loaded and wastes nothing, though it is thin enough that the brevity reflects under-specification as much as crispness.

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?

With an output schema present and zero parameters, the description need not explain return values, so the core need is met. The gap is disambiguation: with both 'get_ddns_config' and 'get_dynamic_dns_config' in the sibling set, the agent has no basis from the description to choose 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?

The tool takes zero parameters, so per the rubric the baseline is 4. There is nothing for the description to disambiguate, and the empty schema is unambiguous.

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 gives a clear verb+resource (get DDNS configuration) and an agent can tell it is a read. However, the sibling list contains a near-identical 'get_dynamic_dns_config' tool, and nothing in the description distinguishes the two, nor does it clarify scope (e.g. current DDNS entries vs. global DDNS feature settings).

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?

There is no when-to-use guidance, no prerequisites, and no mention of the obvious alternatives (get_dynamic_dns_config, add_ddns, delete_ddns, get_ddns_log). The agent must infer usage purely from the name.

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