set_hostname

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

With no annotations present, the description carries the full burden of behavioral disclosure. It simply states 'modify' without explaining whether the change takes effect immediately, requires a reboot, or has side effects. This is a significant gap for a write operation.

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 a single, short phrase with no wasted words, making it highly concise and front-loaded. However, its brevity borders on under-specification, though it still serves as a clear, efficient statement of the tool's purpose.

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 simple setter tool, a short description might be acceptable, but this one lacks any behavioral details or parameter constraints. The presence of an output schema reduces the need to explain return values, but the description still feels incomplete without usage context or effect information.

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 schema description coverage is 0%, and the description does not elaborate on the 'hostname' parameter. While the parameter name is somewhat self-explanatory, the description does not provide validation rules, allowed formats, or length constraints, which is necessary when the schema lacks descriptions.

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 '修改路由器主机名' clearly states that the tool modifies the router hostname, using a specific verb and resource. It distinguishes itself from siblings by explicitly targeting the hostname, which is a unique resource among the listed tools. However, it lacks any explicit comparison to alternatives.

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 other configuration tools. There is no mention of prerequisites, conditions, or when not to use it. The user is left without any contextual direction.

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