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

With no annotations provided, the description carries the full burden of behavioral disclosure. It prominently warns that the deletion is DESTRUCTIVE and irreversible, requires authentication, and clarifies that the actual destructive action happens only after executeConfirmedAction is called. This is excellent transparency for a deletion-capable tool.

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 compact and front-loaded: action, danger warning, authentication, required input, and next step all fit in a few sentences. Every sentence contributes necessary operational or safety information without redundant filler.

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 description is sufficiently complete for a mutation tool with no output schema: it covers required input, authentication, return value, and the follow-up action. The only minor gap is that the sessionKey usage is not echoed in the description, though the schema already documents it clearly.

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 coverage is 50%, so the description must compensate at least partially. It adds a required-hostname note with a concrete FQDN example ('ns1.example.com'), which helps clarify expected format. However, it does not explain the semantic relationship to host/glue records beyond that, and it leaves the sessionKey parameter entirely to 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?

States a specific action ('Stage deletion') on a specific resource ('host/glue record'), which clearly distinguishes it from sibling delete tools like deleteDnsRecord, deleteVpsInstance, and deleteSshKey. The verb and object make the tool's purpose immediately understandable.

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 clear operational guidance: authentication is required, hostname is mandatory, the call returns an actionId, and executeConfirmedAction should be called only if the user approves. It does not explicitly contrast this tool with alternative deletion paths, but the staged-deletion workflow is clearly spelled out.

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