get_firmware_version

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

The description adds no behavioral information beyond the readOnlyHint annotation. It simply restates the operation in Chinese. No mention of authentication, response format, or side effects (though none expected).

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, succinct phrase that is easy to parse. It is appropriately sized for a trivial getter.

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 parameterless getter with an output schema, the description is minimally sufficient. However, it lacks contextual guidance (e.g., that it returns the router's own firmware, not AP firmware), which is a small gap given the sibling tool.

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 has zero parameters, and the description appropriately mentions nothing about parameters. The empty schema covers everything, so the description adds no parameter semantics, but none are needed.

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 '获取当前固件版本' clearly states the tool retrieves the current firmware version, matching the tool name. However, it does not explicitly distinguish this from the sibling tool 'get_ap_firmware_versions', which could cause ambiguity about scope (router vs AP).

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 is provided about when to use this tool versus alternatives. The description gives no context for selecting it over related firmware tools.

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