Get Kernel Settings

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

The readOnlyHint annotation already declares this is a safe read operation; the description adds nothing beyond that (no scope of settings returned, no side effects, no rate limits). For a zero-parameter getter with annotation coverage this is a minimal but redundant statement.

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?

One short phrase with no wasted words, but it is under-specified rather than genuinely concise — it conveys the minimum and nothing more.

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 described, and there are no parameters. Still, the description gives no hint of which settings group this covers, and against dozens of similar get_*_settings siblings, that omission leaves the agent with limited basis for confident selection.

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 takes zero parameters, so there is nothing for the description to document beyond what the empty schema shows. Baseline 4 applies; no parameter context is 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 states a specific verb (获取/get) and resource (内核参数设置/kernel parameter settings), so an agent knows exactly what the tool retrieves. However, it offers no differentiation from the many sibling get_*_settings tools (e.g., get_basic_settings, get_dns_config), so it does not reach a 5.

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?

There is no guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. It simply names the resource without context for selection.

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