ip_arp_status

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

No annotations are provided, so the description carries the full burden. The '(read-only)' label is a valuable disclosure that this operation is non-destructive and safe to invoke. However, it does not describe the output format, whether both IPv4/IPv6 entries are shown, or how entries are ordered, leaving some behavioral gaps.

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?

Four words ('ARP table (read-only)') with zero filler. The core resource is front-loaded and the behavioral modifier is delivered in a parenthetical. Every word earns its place.

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 read-only status tool, the description is largely sufficient. With no output schema present, a brief note on what the ARP table entries contain (e.g., IP/MAC/interface) would improve completeness, but the tool's trivial nature keeps this gap minor.

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 no parameter documentation is needed. The description appropriately focuses on the tool's purpose rather than parameters, which is the correct baseline for a parameterless 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 states a specific resource ('ARP table') and its read-only nature, making the tool's function immediately clear. It does not explicitly differentiate from siblings like ip_route_status, ip_session, or dhcp_status, but the distinct 'ARP table' resource is unambiguous.

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 given on when to use this tool versus alternatives. There are no exclusions, no mention of related sibling tools, and no context about scenarios where the ARP table would be needed (e.g., debugging layer-2 resolution issues).

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