tools_massdns

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

The description discloses no behavioral traits. It does not mention the tool's high-speed DNS querying, potential network noise, required privileges, output behavior, or any side effects. With no annotations provided, the description carries the full burden for transparency, and it completely fails to do so.

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 sentence, which is concise, but it is under-specified rather than appropriately sized. It omits essential details and does not front-load useful information. For a tool with multiple parameters and no annotations, this is over-brevity, not effective conciseness.

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 tool's complexity (MassDNS requires parameters for domain, wordlist, resolvers, and additional arguments), the complete absence of annotations, no output schema, and a one-sentence description, the contextual information is wholly inadequate. The agent cannot understand how to use the tool or what results to expect.

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 four parameters (domain, wordlist, resolvers, additional_args) all with default empty strings and zero description coverage. The description does not attempt to explain the purpose or format of any parameter, leaving the agent without sufficient information to construct correct invocations.

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 'Execute MassDNS resolver.' states a specific action (execute) and resource (MassDNS resolver), but it does not explain what MassDNS does beyond being a resolver. It is minimally clear but lacks detail to distinguish it from sibling DNS tools like subfinder or gobuster, making the purpose somewhat vague.

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. The description does not mention use cases, prerequisites, or scenarios where MassDNS would be preferred over other DNS enumeration tools. No exclusions or alternative tool references are provided.

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