hcloud_list_firewall_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 the safety profile is covered. The description adds essentially nothing beyond that: it does not mention ordering defaults, the auto-paginate soft-cap behavior, or that only actions scoped to the given firewall are returned.

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?

Two sentences, front-loaded with the core operation, with no filler. The trailing sentence about URI parameters is low value but not harmful, so the definition stays tight without being maximally economical.

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 tool with complete schema documentation and annotations, this is close to adequate. What's missing is disambiguation from the singular get_firewall_action and the broad list_actions siblings, plus any hint about the shape of returned actions, which no output schema covers.

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 every parameter (id, page, per_page, sort, status, auto_paginate) is already documented in structured form. The description's only parameter-related sentence points at "URI parameters" without adding format, defaults, or interaction semantics, so it neither helps nor misleads.

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?

"List Actions for a Firewall" states a specific verb (list) and resource (firewall actions), so the operation is unambiguous. It does not, however, distinguish itself from siblings such as hcloud_list_actions, hcloud_get_firewall_action (singular), or hcloud_get_firewalls_actions (plural scope), so an agent must infer the distinction from names alone.

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?

"Use the provided URI parameters to modify the result" is not a when-to-use rule; it restates that filters exist. There is no guidance about when to pick this over hcloud_get_firewall_action for a single action or hcloud_list_actions for a global listing, and no prerequisites are given.

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