Delete DNS Zone RRSet

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

The annotations already mark the operation as destructive and non-read-only, so the description adds useful context by stating the deletion is permanent and by flagging the change-protection precondition. This goes beyond what annotations alone convey.

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 two short sentences with the primary action front-loaded and the critical precondition immediately after. Every word earns its place and there is no redundant restating of the schema.

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 simple destructive operation with full parameter documentation and safety annotations, the description provides the essential behavioral context: permanence and the change-protection requirement. It could mention related record-level operations, but nothing critical is missing for invoking this tool 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?

The input schema fully describes all three parameters, including the type enum and the id_or_name flexibility. The description does not add additional parameter-level meaning, so the baseline score of 3 is appropriate.

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 names the exact operation — deleting an RRSet from a DNS zone — and adds the important qualifier 'permanently.' This distinguishes it clearly from sibling tools like delete_zone, update_zone_rrset, and remove_zone_rrset_records.

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 implies this tool is for removing an entire RRSet and gives one explicit exclusion: it must not be change-protected. However, it does not point to alternatives such as remove_zone_rrset_records for partial record removal, nor does it explain how to handle a protected RRSet.

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