panelica_domains_get_v1_domains

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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds the required oauth scope (domains:read) and the HTTP method, which are useful invocation details beyond the annotations. It does not mention pagination or response shape, but for a no-parameter read-only listing this is a modest gap.

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 core action, "List domains", followed by endpoint, category, scope, and read-only status. It is appropriately concise, though "Read-only" and the category line are partially redundant with the annotations and the tool name.

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 zero-parameter, read-only, list operation with rich annotations, the description is minimally adequate. However, there is no output schema and the description does not mention what the returned domain list contains, whether it is paginated, or any scoping semantics, so the agent must assume those details.

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 has zero parameters and an empty input schema, so there is no parameter semantics burden for the description. Per the baseline for tools with no parameters, a score of 4 is appropriate.

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 clearly states the operation: "List domains" with the HTTP endpoint GET /v1/domains and category Domains. It names the specific verb and resource, so there is no ambiguity about what the tool does. However, it does not explicitly distinguish itself from sibling endpoints such as panelica_domains_get_v1_domains_id, so it stops short of full sibling differentiation.

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 provides a required scope (domains:read) and states the operation is read-only, which are prerequisites rather than usage guidance. It gives no indication of when to choose this tool over alternatives like panelica_domains_get_v1_domains_id or panelica_accounts_get_v1_accounts_id_domains.

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