proxmox_cluster_firewall_rule

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

The description notes that create, update, and delete actions are 'elevated', implying higher privilege requirements. This is a behavioral trait beyond what the schema provides. However, it does not disclose other side effects, such as whether list returns all rules or if updates are partial or full, nor does it mention idempotency or error behaviors.

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 and front-loaded with 'Manage cluster firewall rules'. It is concise but overly terse, compressing multiple actions into a list without structural separation. Every word serves a purpose, but the format could be improved (e.g., using bullet points or separate sentences) for better readability.

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 the tool's complexity (17 parameters, no output schema or annotations), the description is severely incomplete. It does not explain when each action is appropriate, what the return values look like, error conditions, or prerequisites. An agent would struggle to use this tool correctly based solely on the description.

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 schema has very low description coverage (18%), with many parameters lacking meaningful descriptions. The tool description does not add any parameter-level information beyond the action list. For example, 'pos', 'rule_action', and 'type' are not explained in context. The description fails to compensate for the poor schema coverage.

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 'Manage cluster firewall rules' and lists the supported actions (list, get, create, update, delete) with brief explanations. This distinguishes the tool from siblings like proxmox_cluster_firewall (which likely manages firewall options) by focusing on individual rule operations. However, the purpose is conveyed through a list rather than a unified statement.

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 provide any guidance on when to use this tool versus alternatives such as proxmox_cluster_firewall_group or proxmox_guest_firewall_rule. There are no prerequisites, constraints, or examples to help an agent decide between actions or understand typical workflows.

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