panelica_domains_get_v1_domains_id_spf

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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, and the description adds a useful authentication requirement ('Required scopes: domains:read') plus 'Read-only'. This reinforces the read-only, side-effect-free behavior without contradicting 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 'List spf', followed by endpoint, category, scopes, and read-only status. It is efficiently structured, though 'Category: Domains' and 'Read-only' add only marginal value when the name and annotations already convey them.

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 simple one-parameter read-only endpoint, the description covers the route, auth scope, and safety profile. However, with no output schema it does not state what the response contains (e.g., the domain's SPF records), which leaves a small but real gap for an agent selecting or invoking the 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 schema has 100% coverage for the single 'id' parameter, so the description doesn't need to explain it. The endpoint /v1/domains/:id/spf echoes that 'id' is a path parameter, but no additional meaning or formatting is provided beyond the schema.

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 'List spf' and gives the exact HTTP path GET /v1/domains/:id/spf, so the verb and resource are identifiable. It does not explicitly differentiate itself from sibling SPF/DKIM tools, but the resource name and read-only verb are enough to avoid confusion.

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?

There is no guidance on when to call this tool instead of related domain tools such as panelica_domains_get_v1_domains_id_dkim or panelica_domains_patch_v1_domains_id_spf. The description mentions required scopes and read-only status, but that is access metadata, not usage routing.

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