list_vm_firewall_rules

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

The description lacks behavioral details beyond listing required parameters. With no annotations, it does not disclose that the operation is read-only, requires permissions, or any potential side effects. The agent must infer from the tool name.

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 very concise at two short sentences plus argument list. It is front-loaded with the purpose and then lists parameters efficiently. However, it may be too minimal in content.

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 simplicity (list operation) and the presence of an output schema (which likely defines return structure), the description is moderately complete. However, it omits details like whether the list is sorted, paginated, or filtered, and does not mention required permissions.

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 input schema has 0% description coverage. The description adds one-line explanations ('The node name', 'The VM ID') which provide minimal context beyond the parameter titles. This adds some value but does not fully compensate for the lack of schema descriptions.

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 the action ('List') and the resource ('firewall rules for a QEMU VM'). The tool name further reinforces this. It does not explicitly distinguish from sibling tools like list_container_firewall_rules, but the specificity is adequate.

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?

No guidance is provided on when to use this tool versus alternatives such as list_cluster_firewall_rules or list_container_firewall_rules. There is no mention of prerequisites, context, or when not to use it.

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