DNS_deleteDNSRecordsV1

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

Without annotations, the description must disclose behavioral traits. It only says 'Delete DNS records', which is already implied by the name. It does not mention whether the operation is irreversible, what happens if filters are omitted, or how results are returned. The filtering behavior described is not reflected in the schema, adding opacity.

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 front-loaded with the core action, but it expands on filtering details that are inaccurate given the schema. It could be shorter and more precise. The mention of 'Update zone records' adds value but also extra length. Overall, it is somewhat concise but not optimally structured.

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?

The tool is simple with one parameter, but the description omits important context such as what happens after deletion (e.g., success response), whether the domain must exist, or how to specify records to delete. The contradiction between described filters and actual schema leaves the agent without complete guidance.

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 one parameter 'domain' with 100% coverage, but the description introduces 'name' and 'type' filters that are not part of the schema. This misleads the agent into expecting parameters that do not exist. The description fails to clarify the actual parameter usage or add meaning beyond the schema's 'Domain name'.

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 states 'Delete DNS records' and 'remove specific DNS records', which clearly indicates the tool's purpose. However, it mentions filtering by name and type that are not present in the input schema, causing confusion. The purpose is clear in general but compromised by the mismatch.

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 explicitly instructs to use the 'Update zone records' endpoint when dealing with multiple records of the same name and type and needing to delete only part of them. This provides a clear alternative for a specific edge case, aiding decision-making. However, it lacks guidance on prerequisites or when not to use this tool.

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