monitor_dns_propagation

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

The verb 'Check' implies a read-only operation and the server list adds useful scope, but with no annotations provided the description carries the full burden of behavioral disclosure. It does not explain what the response represents, how server disagreement is handled, or whether there are timeouts/rate limits.

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?

A single, front-loaded sentence communicates the core action and scope without unnecessary words. Every phrase 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?

With no output schema and no annotations, the description leaves important context unstated: how expectedValue is used, what the return status looks like, and when to prefer this over monitor_dns_lookup. It is adequate for a simple check but not complete for an agent needing to choose and invoke it correctly.

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?

Schema description coverage is only 33%, and the description does not compensate. It adds no explanation for recordType or expectedValue, so an agent must infer how those parameters affect propagation checking. The description only reinforces the domain-centric purpose already visible in the schema.

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 a specific verb ('Check'), a specific resource ('DNS propagation'), and the scope ('multiple public DNS servers: Google, Cloudflare, OpenDNS, Quad9'). It is differentiated enough from the sibling monitor_dns_lookup by focusing on propagation across public resolvers, though it does not explicitly name the alternative.

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 use case is implied: check DNS propagation after DNS changes or verify records across public resolvers. However, there is no explicit guidance about when to choose this over monitor_dns_lookup or other DNS-related tools, and no exclusion criteria.

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