cluster_firewall_status

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

The description indicates a read operation (no mutations), which is the primary behavioral trait. No annotations are provided, so the description carries the full burden; it does not disclose additional behaviors like authentication needs or return value structure. For a simple read tool this is adequate but minimal.

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 short (two sentences plus an Args line), front-loading the purpose with '[READ]'. Every word serves a purpose, making it efficient. However, the 'Args' block is informal and could be more structured.

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 no output schema, the description should indicate what the tool returns (e.g., a boolean or JSON object). It only mentions reading options 'notably whether it is enabled' but doesn't clarify the return format. For a single-parameter read tool, this is a significant gap.

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?

With 0% schema description coverage, the description must compensate for parameter documentation. It explains that 'target' is a 'Proxmox target name from config', which provides some context but remains vague—no valid values, format, or source are given. This is insufficient for an agent to reliably populate the parameter.

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 it reads 'cluster-wide firewall options', specifically noting whether the firewall is enabled. This distinguishes it from per-VM firewall tools like vm_firewall_rules_list, though it does not explicitly name siblings.

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 description includes a '[READ]' prefix indicating read-only use, but it does not provide explicit guidance on when to use this tool versus alternatives or mention any prerequisites. Context from sibling tools implies cluster-level vs VM-level distinction, but this is not stated.

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