manage_firewall_zone

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

Annotations already indicate destructiveHint=true and idempotentHint=false. The description adds value by explaining the lifecycle (create, then assign networks, then create policies) and the restriction on deleting default zones, which goes beyond the annotations.

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 concise (four sentences) and front-loaded with the primary purpose. Every sentence contributes meaningful information 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 CRUD tool with no output schema, the description adequately explains the concept and workflow. It could mention that zoneId is required for update/delete (implied by schema) or specify return behavior, but overall it is sufficiently complete.

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 100%, with each parameter having a description. The description adds some context (e.g., naming convention 'zone-{purpose}') but does not significantly enhance understanding beyond the schema. Baseline 3 is appropriate.

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 explicitly states the tool creates, updates, or deletes custom firewall zones, with concrete examples ('IoT', 'Guest', 'Cameras'). This clearly distinguishes it from sibling tools like list_firewall_zones (read-only) and manage_firewall_policy (policy management).

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 provides context on when to use the tool (per security boundary) and mentions default zones cannot be deleted. However, it does not explicitly guide when not to use it or compare with alternative tools like list_firewall_zones for inspection or manage_firewall_policy for policies.

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