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

Beyond the destructive/openWorld annotations, the description discloses the confirmation prompt, what that prompt displays (method, path, body), that responses are always arrays, and that some endpoints incur real charges such as domain renewals and cloud orders. These are exactly the side-effect details an agent cannot infer from the structured fields.

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?

Front-loaded with the core routing statement and the prerequisite describe_endpoint step, with no filler sentences. The parenthetical enumeration of covered resource types is long but earns its place by helping an agent recognize whether its target is in scope.

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 an open-world, destructive, 8-parameter generic client, the description covers routing, prerequisite discovery, path construction, response shape and monetary risk. Because an output schema exists, it correctly omits return-value documentation and spends its length on the hazards instead.

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 75%, and the description adds the base URL that `path` is relative to plus a concrete path example, and clarifies that `body` is an object except for the renew endpoint where it is an array. Pagination and query parameters are left entirely to the schema, which already documents them, so the baseline applies.

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 gives a specific verb and resource (call any ZoneID API v2 endpoint) and immediately scopes it against the dedicated tools it is not meant to replace, listing concrete example domains such as cron, SSH keys and Redis. An agent can tell from the text alone that this is the generic escape hatch rather than one of the typed siblings.

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?

It explicitly states the selection rule ('for everything the dedicated tools don't cover') and prescribes the workflow ordering by requiring describe_endpoint before body construction. It also distinguishes methods behaviourally: GET/OPTIONS run directly, POST/PUT/DELETE trigger confirmation, so the agent knows the cost of choosing each method.

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