list_ipv6_static_bindings

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

The readOnlyHint annotation already indicates this is a safe read operation, and the description's 'list' verb is consistent with that. However, the description adds no behavioral context beyond the name, such as what data is returned or any limitations. With annotations covering the safety profile, this is acceptable but not enriched.

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, front-loaded sentence with no wasted words. It is appropriately sized for a simple read-only list operation.

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?

Given the low complexity (0 parameters, read-only, output schema exists), the description is minimally viable. However, it lacks any clarification of what 'static assignments' means in this context (e.g., DHCPv6 vs. prefix delegation), and does not mention related tools. The output schema covers return structure, but usage context is still thin.

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, so the schema fully covers them (100% coverage by virtue of being empty). The description adds no parameter details, but none are needed. Baseline for 0 parameters is 4.

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 '列出 IPv6 前缀静态分配' clearly states a list operation for IPv6 prefix static assignments, which is specific and distinguishable from siblings like list_dhcp_static_bindings. However, it does not explicitly differentiate from similar IPv6-related list tools, preventing a higher score.

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 alternatives such as list_ipv6_neighbors or list_dhcp_static_bindings. There is no mention of context, prerequisites, or exclusion criteria, leaving the agent without direction.

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