Create SMTP Auth Profile

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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true and destructiveHint=false, so the write/mutation nature is covered structurally. The description adds essentially nothing beyond that — no mention of required permissions, effect of re-creating an existing profile, or the domain-scoped key semantics.

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?

A single front-loaded sentence with a bolded purpose label and zero filler. It is tight, though the brevity comes partly from deferring content rather than compressing it.

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?

This is a creation tool taking a nested, unrestricted request body, with no output schema and no annotations describing side effects. The description offloads the actual payload contract to an external OpenAPI document, leaving an agent unable to construct a valid call from the definition alone.

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 description coverage is 100% (key = 'Profile mkey', domain = 'Domain name'), so the schema carries the two required parameters and the baseline is 3. The description's reference to the engine OpenAPI adds no field-level detail, and the nested 'settings' body is left as an open object with no semantics anywhere.

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+resource ('Create SMTP Auth Profile'), which is unambiguous on its own. It does not distinguish itself from the sibling CRUD set (smtp_auth.list/get/update/delete), though the verb 'create' makes the intent clear enough to select it.

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?

No when-to-use guidance, prerequisites, or alternative routing is given. The only hint is a pointer to the engine OpenAPI for body fields, which is a documentation deferral rather than usage guidance.

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