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

The destructiveHint annotation already signals the destructive nature, but the description does not add any further behavioral context such as irreversibility, impact on associated records, or idempotency. It merely restates the use of zone name, which adds no transparency beyond the annotation.

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 short, but the second sentence ('Delete a DNS Zone using zone name') largely repeats the first, making it redundant. A single sentence would be equally informative without the repetition.

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 destructive tool with no output schema and minimal parameter documentation, the description is insufficient. It does not state that deleting a zone may cascade to all records, whether the operation is reversible, or what response status to expect. The lack of context on these aspects leaves the agent under-informed.

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 0%, so the description must compensate by explaining parameter meaning. The only mention is 'using zone name,' which is merely a restatement of the parameter name and does not clarify its format (e.g., FQDN vs. simple name) or purpose. The required x-request-id and optional x-trace-id are not explained at all.

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 action (Delete) and the resource (DNS zone) in the first clause. It also distinguishes from sibling tools like deleteDnsZoneRecord by specifying 'DNS Zone' rather than a record, making the purpose unambiguous.

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 deleteDnsZoneRecord or bulkDeleteDnsZoneRecords. It lacks any context about prerequisites or situations where deletion should be performed.

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