set_firewall_settings

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

Discloses that it replaces settings and that no partial updates are allowed, indicating a destructive overwrite. However, no annotations are provided, and the description does not mention permissions, side effects on active connections, or error conditions.

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?

Two concise sentences front-loaded with the core action and a key constraint. No redundant information.

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?

Despite having an output schema, the description lacks context about return values, success/failure indicators, or what 'replace' entails (e.g., immediate effect, need for reboot). For a tool with 8 required boolean parameters, more guidance is needed.

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 coverage is 0%, so description provides no additional meaning for parameters. The parameter names (e.g., 'keep_rules', 'allow_loopback') are somewhat self-explanatory, but the description does not explain their purpose or impact, leaving ambiguity for less obvious ones like 'multicast_dns'.

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?

Description states 'Replace the firewall settings' which is a clear verb and resource. It distinguishes from sibling tools like get_firewall_settings (read) and enable/disable firewall (different action), but could be more explicit about the scope.

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 on when to use this tool versus alternatives like partial updates (not supported) or replacing rules only. Only notes that all fields are required, but lacks context for decision-making.

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