ddns_enable

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

With no annotations provided, the description carries the behavioral burden. 'write — requires confirmation' meaningfully discloses that this is a mutating operation and that a confirmation step is involved. Still, it does not explain what enabling/disabling DDNS does in practice or how confirmation is obtained, leaving gaps.

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 concise and front-loaded: the core action appears first, with the write/confirmation caveat in a parenthetical. It wastes no words, though it could be slightly more informative about parameters and the confirmation flow.

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 is a write operation with four parameters, no annotations, and no output schema, so the description needs to explain more. The current text covers the basic action and the need for confirmation, but does not explain how the confirmation-related parameters interact, what the expected outcome is, or what prerequisites exist. An agent calling this tool without additional context would be guessing.

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%, so the description must compensate for undocumented parameters. It maps loosely to onoff via 'enable/disable' and hints at confirmation fields via 'requires confirmation', but it does not explain user_code, confirm_token, or confirmation_id. This is insufficient for an agent to confidently supply all 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 and resource: 'Enable/disable DDNS', which clearly identifies the operation this tool performs. It also distinguishes itself from siblings like ddns_show, ddns_log, and ddns_forceupdate by implying status viewing/logging/force-updating are separate actions.

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 verb 'Enable/disable' gives an implicit usage context: use this when toggling the DDNS state. However, it does not explicitly state when to avoid this tool or compare it to alternatives such as ddns_show or ddns_forceupdate. The confirmation note is a hint but not a full usage guide.

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