pve_create_cluster_firewall_rule

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 but offers minimal information. It states 'Create' which implies a write/mutation operation, but doesn't mention required permissions, whether the rule is applied immediately, potential side effects, or error conditions. For a security-critical tool with 10 parameters, this is insufficient behavioral context.

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 extremely concise at just three words, with zero wasted language. It's front-loaded with the essential action and resource. While it could benefit from additional context, what's present is maximally efficient without redundancy.

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 complex firewall rule creation tool with 10 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what happens after creation, how rules are ordered/prioritized, whether changes are immediate, or what permissions are required. The agent would struggle to use this tool effectively without significant trial and error.

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 the schema already documents all 10 parameters with clear descriptions. The description adds no additional parameter information beyond what's in the schema, which is acceptable given the comprehensive schema coverage. This meets the baseline expectation when the schema does the heavy lifting.

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 verb ('Create') and resource ('cluster firewall rule'), making the purpose immediately understandable. However, it doesn't distinguish this from sibling tools like 'pve_create_vm_firewall_rule' or 'pve_list_cluster_firewall_rules', which would require mentioning the cluster-level scope or contrasting with VM-level 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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites (e.g., needing cluster permissions), when to use it over VM-level firewall rules, or refer to sibling tools like 'pve_list_cluster_firewall_rules' for verification. This leaves the agent without context for proper tool selection.

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