network_reverse_dns

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

With no annotations, the description fails to disclose important behavioral traits such as whether the tool requires network access, any limitations on IP addresses, or the default behavior when omitting the worker_id parameter. It does not mention side effects or error conditions.

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 includes unnecessary 'Menu ID:' prefix and a suggestion to use describe_tool. While functional, it could be tighter. The core information is present but padded.

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?

The tool has no output schema, yet the description only hints at output (hostnames, server names). It does not explicitly state what the tool returns or how to interpret results. The additionalProperties flag is also not addressed. For a simple tool, it lacks completeness.

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 only parameter (worker_id) is fully described in the schema, and the tool description adds no extra meaning. Baseline score of 3 is appropriate given 100% schema coverage.

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 clearly states it performs reverse DNS lookups to convert IP addresses to domain names, which is a specific verb+resource. It distinguishes from sibling DNS tools like network_dns and network_dns_propagation by specifying the reverse operation.

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 does not provide any guidance on when to use this tool vs other DNS tools. It neither mentions prerequisites nor excludes scenarios. The agent has no context to decide between forward and reverse lookup tools.

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