Cluster Firewall Settings

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

Annotations already declare destructiveHint=true and readOnlyHint=false, and the description's 'Query/manage' plus 'update_options' is consistent with those. It adds the useful 'elevated' permission note, but it does not explain the consequences of destructive updates, such as whether enabling the firewall can disrupt connectivity.

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 front-loaded sentence with a compact action map; there is no filler. The pipe-separated list is information-dense and fast to parse, though it is slightly less readable than separate bullet lines.

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 multi-action tool with no output schema, the description does not specify which parameters apply to each action or what the read actions return. The schema documents parameter meanings but not the action-parameter binding, which an agent needs for correct invocation; the action list covers basic selection but not full usage.

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 action parameter has no schema description, and the description supplies meaning for all four action values. Other parameters (type, enable, policy_in, policy_out, log_ratelimit) are already documented in the schema, so the description adds value without repeating those details.

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 states 'Query/manage cluster firewall metadata' and enumerates four concrete actions (get_options, update_options, list_macros, list_refs). The resource is clear, and the action list helps distinguish it from sibling tools for rules, aliases, groups, and ipsets, although those siblings are not explicitly named.

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 action list implies when to use the tool—for firewall options, macros, and refs—and flags update_options as '(elevated)'. However, it does not explicitly state exclusions or name alternative tools such as proxmox_cluster_firewall_rule, leaving routing to inference.

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