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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, and the description mostly repeats this by saying "Read-only." It adds the HTTP endpoint and required scopes as operational context, but does not describe the response contents or any edge behavior, so it adds limited value beyond the annotations.

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 short and front-loaded with the purpose, followed by endpoint, category, scopes, and safety profile in compact lines. It is slightly redundant with the annotations and includes a low-value category line, so it is not a perfect 5.

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 a parameterless read-only configuration getter, the description is essentially complete for invocation: it identifies the resource, endpoint, auth scope requirement, and read-only nature. The lack of an output schema means return fields are not detailed, but the tool's intended response is clear from its name and description.

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 input schema has zero parameters and 100% schema coverage, so there is nothing for the description to clarify. Baseline 4 applies because no parameter documentation is needed.

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 and resource: "Get SMTP relay config." The HTTP GET method and "Read-only." line make it easy to distinguish from the sibling patch tool, though it does not explicitly name that alternative.

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?

Usage is implied by the action verb and resource: call this when you need the current SMTP relay configuration. It does not state when not to use it or explicitly route to panelica_smtp_relay_patch_v1_smtp_relay for modifications.

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