hcloud_list_zone_actions

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

The annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the tool returns all Actions for a Zone and that URI parameters modify results, but it omits pagination behavior, auto-pagination soft-cap effects, filtering/sorting behavior, and response characteristics.

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-loads the core purpose: listing Actions for a Zone. The final sentence about URI parameters is weak filler, but overall the definition is appropriately sized with no major structural issues.

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 read-only list operation with full schema coverage and annotations, the description is mostly adequate. However, because there are many action-list siblings and no output schema, it should clarify pagination/auto_paginate behavior or when to choose this endpoint over broader action-listing tools.

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 schema already documents id_or_name, page, per_page, sort, status, and auto_paginate in detail. The description only refers generically to "URI parameters" and adds no meaning beyond the schema, so the baseline score 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 states a specific verb and resource: it lists Actions for a Zone and says it returns all Actions for a Zone. This is clearer than a tautology, but it does not distinguish this tool from close siblings such as hcloud_get_zones_actions or hcloud_list_actions.

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 no guidance on when to use this tool instead of hcloud_list_actions, hcloud_get_zones_actions, or hcloud_get_zone_action. The only usage-like sentence, "Use the provided URI parameters to modify the result," does not explain selection criteria, prerequisites, or exclusions.

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