ip_dnsforward

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

There are no annotations, so the description carries the behavioral burden. It does explicitly disclose 'read-only', which is a meaningful safety trait for a zero-parameter query, but it says nothing about the output contents, formatting, or any operational context beyond that.

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 very short and contains no filler; the key 'read-only' qualifier is included. It is appropriately sized for a simple no-parameter query, though the phrasing is minimal rather than fully explanatory.

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 zero-parameter, read-only tool, the description is nearly adequate, but it lacks any explanation of what a 'DNS forward table' contains or how this differs from sibling DNS status commands. An agent could invoke it, but may not know why it is the right choice.

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 input schema has zero parameters, so there is no parameter burden to document. The baseline of 4 applies because no parameter descriptions are needed and nothing is left ambiguous.

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 is essentially a noun phrase that restates the tool name ('DNS forward table') with only 'read-only' adding behavior. It does not state a verb such as 'show' or 'get', and it does not distinguish this tool from similar DNS/lookup siblings like show_dns, sys_dnsCacheTbl, or ip_lanDNSRes.

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 ip_dnsforward versus the many DNS-related or table-view sibling tools. No exclusions, alternatives, or context-dependent selection criteria are provided.

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