put_connection_ddns_provider

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

With no annotations, the description carries full burden but only lists error codes without explaining behavior. It does not disclose whether settings are merged or replaced, what happens on failure, or if there are side effects (e.g., service restart). The error codes hint at possible issues but are not contextualized.

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 very short and front-loaded, but the error code list is not integrated into the narrative. It is concise but misses important information that would make it earn its place.

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 5 parameters, an output schema (exists but not shown), and the complexity of DDNS configuration, the description is too sparse. It does not explain what DDNSConfig encompasses, how the tool interacts with the system, or any required prior states.

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 60% (hostname, password, user have descriptions; provider and enabled do not). The description adds no extra meaning beyond the schema—no details about provider values, enabled default, or parameter constraints. It fails to compensate for the 40% undocumented 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 says 'Set the DDNSConfig', which clearly indicates the verb (set) and resource (DDNSConfig). However, it does not differentiate itself from sibling tools like put_connection_config or get_connection_ddns_provider, missing an opportunity to clarify its specific scope.

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 guidance on when to use this tool versus alternatives. No prerequisites (e.g., need to have DDNS configured), no caution about overwriting existing config, and no mention of when not to use it.

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