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

The description mentions using 'Cloudflare DoH endpoints', which suggests an external dependency and likely a read-only operation. However, with no annotations, it lacks details on safety, side effects, or authorization requirements.

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, concise sentence that front-loads the key information. Every word is meaningful, and there is no redundancy or unnecessary detail.

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 two-parameter tool, the description provides basic context but lacks details on return values, supported record types beyond those listed, and potential limitations. It is adequate but not comprehensive.

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?

With 0% schema description coverage, the description should compensate but does not explicitly explain the 'domain' and 'type' parameters. It hints at possible values for 'type' by listing record types, but offers no additional meaning beyond 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 the tool checks DNS propagation status for specific record types (MX, TXT, A, CNAME) using Cloudflare DoH endpoints. It distinguishes from siblings like 'auditDnsSecurity' which likely focuses on security aspects.

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 provides no guidance on when to use this tool versus alternatives, such as other DNS-related tools like 'auditDnsSecurity' or 'lookupWhois'. No exclusions or prerequisites are mentioned.

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