get_ap_firmware_versions

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

Annotations declare readOnlyHint=true, so the agent knows this is a safe read. The description adds no behavioral detail beyond the literal read-only fetch (e.g., no mention of what versions are returned or whether it can be called without APs present), but it does not contradict the annotation. With the annotation already covering safety, the minimal description is acceptable.

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, front-loaded Chinese sentence that conveys the tool's purpose with no filler. Every word earns its place; no restructuring is needed.

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 zero-parameter read-only getter with an output schema, this description is adequately complete. It could have clarified whether the list refers to current firmware versions on AP devices or available firmware versions, but the low complexity and presence of an output schema reduce the need for extra context.

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 100% schema coverage (empty object), so there are no parameter semantics the description needs to add. The baseline of 4 applies for a zero-parameter tool.

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 uses a specific verb ('获取' / get) and resource ('AP 固件版本列表'), clearly indicating a list/read operation. It differentiates from sibling mutation tools like restart_ap and upgrade_ap_firmware.

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 such as get_ap_group_config or upgrade_ap_firmware. The sibling list also offers no explicit context, leaving the agent to infer usage from the name alone.

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