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

The description explicitly states 'Mutating: changes server state', which aligns with readOnlyHint=false and adds a clear side-effect warning. It also provides required scope 'domains:write', which is useful auth context beyond the annotations. However, it does not disclose error behavior, idempotency consequences (already hinted false), or what happens on duplicate creation.

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 with the core purpose, followed by short labeled metadata lines for HTTP method, category, scope, and mutation effect. No filler is present, though some lines repeat information already inferable from the tool name or annotations.

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 a body whose schema is explicitly not statically declared, the description should compensate by naming essential or common body fields, but it does not. An agent has no way to construct a meaningful create-autoresponder request beyond supplying the domain id, and no return/response expectations are described.

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 100%: 'id' is described as a path parameter and 'body' as the application/json request body, so the schema carries the basic semantics. The description adds no parameter-level detail, and the body remains opaque ('Schema not statically declared'); per the coverage rule, the baseline of 3 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 opens with the verb-resource pair 'Create email autoresponder' and confirms it with the HTTP POST path, so the tool's action and target are unmistakable. It is clearly distinguished from the sibling GET list tool and the DELETE autoresponder tool, and no other POST sibling covers autoresponders.

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 usage by saying 'Create email autoresponder' and labeling itself as mutating, so an agent can infer to call it when an autoresponder needs to be added to a domain. However, it does not explicitly state when to prefer this over reading existing autoresponders (panelica_domains_get_v1_domains_id_email_autoresponders) or removing one (panelica_email_delete_v1_email_autoresponders_id).

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