Cluster Firewall Groups

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

Annotations already indicate readOnlyHint=false, destructiveHint=true, and idempotentHint=true. The description adds that create, update, and delete require elevated permissions, which is useful beyond the annotations. However, it does not disclose side effects, reversibility, or what happens on conflict, so it only moderately supplements the annotation data.

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 compact and front-loads the actions in a pipe-separated format, avoiding unnecessary prose. It is efficient, though the dense single line could be slightly clearer with a more structured presentation. No words are wasted.

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?

With six parameters, no output schema, and many sibling firewall tools, the description is not complete enough for reliable invocation. It fails to explain required parameter relationships (e.g., group needed for get/create/update/delete), optional parameter meanings, return behavior, or side effects. The action list covers part of the needed context but leaves significant gaps.

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 only 17%, so the description must compensate for undocumented parameters. It does clarify the action enum and that 'get' uses a group name, but it leaves delete, digest, rename, and comment unexplained. An agent would not understand the role of digest or rename for update/delete operations.

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 identifies the resource as cluster firewall groups and enumerates concrete actions (list, get, create, update, delete), so an agent can tell what the tool operates on. It is not perfectly specific because 'Manage' is vague, and it does not explicitly differentiate from sibling tools like proxmox_cluster_firewall_rule or proxmox_cluster_firewall_alias, but the resource name and action list are sufficient for basic purpose clarity.

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 about when to choose this tool over its many siblings, such as proxmox_cluster_firewall, proxmox_cluster_firewall_rule, or proxmox_cluster_firewall_ipset. The action list implies usage patterns, but there are no exclusions, preconditions, or alternative tool references.

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