pve_list_vm_firewall_rules

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action ('List') without details on permissions required, rate limits, output format (e.g., JSON list), pagination, or error handling. For a read operation in a system with many sibling tools, this is insufficient to inform safe and effective use.

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, direct sentence ('List VM firewall rules') with no unnecessary words. It is front-loaded and efficiently conveys the core action, making it easy to parse quickly without wasted verbiage.

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 complexity of firewall management in a virtualization environment, no annotations, and no output schema, the description is incomplete. It lacks details on behavior, output structure, error cases, and integration with sibling tools, leaving significant gaps for an agent to understand how to use this tool effectively.

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 100% description coverage, clearly documenting 'node' and 'vmid' parameters. The description does not add any semantic details beyond the schema, such as examples or constraints (e.g., node must be online). With high schema coverage, the baseline score of 3 is appropriate, as the schema adequately handles parameter documentation.

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 'List VM firewall rules' clearly states the action ('List') and resource ('VM firewall rules'), making the purpose understandable. However, it lacks specificity about scope (e.g., all rules vs. filtered) and does not differentiate from sibling tools like 'pve_list_container_firewall_rules' or 'pve_list_cluster_firewall_rules', which reduces clarity in a crowded toolset.

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. The description does not mention prerequisites, context (e.g., after creating a rule), or related tools (e.g., 'pve_create_vm_firewall_rule' for adding rules), leaving the agent without usage direction.

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