Storage Disk Smart

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

No annotations are provided, so the description carries the full behavioral burden. '查看' implies read-only, but nothing states whether any state is touched, what authentication/profile is needed, or what SMART data is returned. For a tool with zero annotation coverage this is thin, though the read-only implication limits the risk.

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?

A single short, front-loaded sentence with zero waste. It is concise, but the brevity borders on under-specification given the ambiguity with sibling disk tools, so it does not reach the top of the range.

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?

An output schema exists, so return values need not be explained, and the schema fully documents parameters. The low-complexity read operation is adequately covered, but the lack of any sibling differentiation or usage context leaves the definition only minimally complete.

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 100%, so all five parameters (disk, host, port, scheme, profile) are already documented in the schema. The description adds no parameter meaning beyond what the schema provides, so the baseline 3 applies.

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 clear verb and resource (查看/查看硬盘 SMART 信息), so the basic purpose is unambiguous. However, it does not differentiate itself from close siblings like storage_disk_health, storage_disk_info, or monitor_disk, which plausibly cover overlapping disk-status territory. An agent cannot tell from the text alone why it should pick this over those.

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 when-to-use, when-not-to-use, or alternative guidance is provided. Given several sibling tools concerning disk health and info, the absence of routing cues is a real gap. The description offers no condition for selecting this tool over storage_disk_health.

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