List DNS Zone Actions

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

The annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, indicating a safe, read-only operation. The description adds context about the types of actions (imports, TTL changes, protection toggles) but does not disclose additional behavioral traits such as pagination behavior, rate limits, or that it requires a valid zone ID/name. Since annotations cover the core safety profile, the description provides moderate added value.

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 a single sentence of 17 words, perfectly concise and front-loaded with the verb 'List'. Every word adds value, with specific examples but no fluff. It is well-structured and easy to parse.

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?

Given no output schema, the description could explain the structure of the returned data (e.g., 'returns a list of action objects with details like id, status, started_at, finished_at'). It only says 'list all actions', leaving the agent to infer the return format from context or other tools. While not severely incomplete, it is a moderate gap for a tool with five parameters and no output schema.

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%, so the baseline is 3. The description does not add any meaning beyond the schema's parameter descriptions; it only mentions 'specific DNS zone' which maps to the 'id_or_name' parameter already described in the schema. No additional clarification or context for using the parameters is provided.

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 verb 'List' and the resource 'actions performed on a specific DNS zone', with concrete examples like imports, TTL changes, and protection toggles. It distinguishes from sibling tools such as hetzner_list_zones (which lists zones) and hetzner_list_certificate_actions (which lists actions on certificates), making the purpose unambiguous.

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 does not explicitly state when to use this tool over alternatives like other list_*_actions tools or when not to use it. The usage context is implied by the resource 'DNS zone' and the readOnlyHint annotation, but no explicit guidance is provided. It neither gives criteria nor exclusions.

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