List Automatic SSL subscriptions

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered. The description adds real value beyond them: the required scope 'certificates:read' and an explicit negative disclosure that sensitive values (ACME server URL, account ID, EAB KID, EAB HMAC key) are never returned.

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?

Two sentences, front-loaded with the action and returned fields, then the security exclusion and auth requirement. The dense field enumeration is informative rather than filler, though the sentence listing returned fields is long.

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?

With no output schema and no parameters, the description must carry the return-value burden, and it does list the returned fields plus the auth scope and sensitive-field exclusions. It stops short of mentioning ordering or result-size behavior, a minor gap for a zero-argument list tool.

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 tool takes zero parameters, so the baseline of 4 applies. The description does not need to explain any parameter syntax and correctly focuses on scope and output instead.

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 verb (List) and resource (customer-owned Automatic SSL subscriptions) and enumerates exactly which fields are returned. An agent can distinguish it from the singular sibling get_automatic_ssl_subscription without opening any schema.

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 'customer-owned' scoping and field list imply a bulk-enumeration use case, and the conventional list-vs-get split with get_automatic_ssl_subscription is inferable. However, no sibling is named and there is no explicit when-to-use or when-not-to-use guidance.

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