pve_get_firewall_rules

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

No annotations are provided, so the description carries the full burden. It only states what the tool returns and the scoping, but does not explicitly mention that it is a read-only operation, any required permissions, or what happens if the VM name is invalid. Given the lack of annotations, more behavioral context is needed.

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, compact sentence that immediately states the resource and scoping. It is front-loaded with the purpose and contains no filler, making it an model of conciseness.

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 annotations and zero parameter documentation, the description is too thin to be fully complete. It fails to explain important behavioral aspects such as required permissions, return format (though an output schema exists), and parameter constraints. More context is necessary for reliable invocation.

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 parameter coverage is 0%, so the description must compensate. It explains that vm_name selects VM-level rules, but it does not describe the expected format of node or vm_name (e.g., name vs. ID), and node is not explained at all. The description offers minimal additional meaning beyond the raw schema.

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 identifies the resource (firewall rules) and the two scopes (node or specific VM). Although the verb 'get' is not explicitly stated in the description, the tool name supplies it. The distinction from sibling tools is clear since none of the siblings deal with firewall rules.

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 clear context on how to use the tool: pass vm_name for VM-level rules, otherwise it operates at node level. It does not mention alternatives, but there are no sibling tools for firewall rules, so the guidance is adequate.

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