hcloud_get_zones_actions

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds that the unfiltered call returns ALL zone actions (a potentially large result set) but says nothing about pagination defaults, sort order, or rate limits beyond what the schema already documents.

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?

Three short lines, front-loaded with the verb and resource, with no redundant prose. Minor noise from anchor-style markdown links ([Zone](#tag/zones), [Actions](#tag/actions)) that carry no meaning for an agent.

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?

There is no output schema and no annotation gaps, and all five optional parameters are documented in the schema, so the basics are covered. What is missing is the context that matters with so many similarly named action-listing siblings: which one to call, and whether results are paginated by default.

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 id, status, sort, page and per_page are all fully documented in the schema. The description's only contribution is the generic phrase "URI parameters," which adds no semantics beyond the schema and is arguably imprecise for query parameters.

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 ("List Actions ... Returns all Zone Actions"), so an agent knows this retrieves the action history for the zones resource. It does not distinguish itself from closely named siblings such as hcloud_list_zone_actions or hcloud_get_zones_actions_id, leaving the agent to guess which listing endpoint applies.

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 only guidance is "Use the provided URI parameters to modify the result," which restates that filtering exists without saying when to filter, when to use this over the per-ID or generic action tools, or what happens with no parameters. No alternatives or exclusions are named.

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